    2008-01-01

    This essay explores different views on the female body articulated within Hebrew medieval texts on women's health care. It also investigates whether texts also integrate women's own perceptions of their bodies, and of their needs and care. I have analysed how this genre of Hebrew literature understood two key issues in the construction of sexed bodies: menstruation and cosmetics.

  2. The virtues of balm in late medieval literature.

    PubMed

    Truitt, Elly R

    2009-01-01

    This article argues that balm, or balsam, was, by the late medieval period, believed to be a panacea, capable of healing wounds and illnesses, and also preventing putrefaction. Natural history and pharmacological texts on balm from the ancient and late antique periods emphasized specific qualities of balm, especially its heat; these were condensed and repeated in medieval encyclopedias. The rarity and cost of balsam, from antiquity through the medieval period, and the high rate of counterfeiting also demonstrate its high demand and significance in medicine and religious ritual. Travel writing and itineraria from the early and central medieval periods added a new layer to ideas about the capabilities of balsam: that it originated from a Christian miracle and was a particularly Christian plant.

  5. Melancholia in medieval Persian literature: The view of Hidayat of Al-Akhawayni

    2014-01-01

    “Melancholia” seems to be the oldest term used to describe the manifestations of depression. Throughout the history of medicine, melancholia has been the focus of consideration of many scholars who have provided varying definitions of this disorder and its manifestations. This continual process has resulted in the gradual development of the concept of melancholia over time. Persian scholars were among the scientists who have studied the melancholia and contributed to its concept. One figure, Al-Akhawayni Bukhari (?-983 AD), a Persian physician whose reputation was based on the treatment of patients with mental problems, investigated this disorder. He described Melancholia and explained its clinical manifestations and treatment methods. Al-Akhawayni provided an early classification of the patients suffering from this disorder. Since the medieval Persian concept of melancholia is not well-known, this paper aims to review Al-Akhawayni’s 10th century knowledge on melancholia which can represent the early concept of this disorder in the Near East.

    2014-01-01

    During the Middle Ages, demonic possession constituted an explanation for an erratic behavior in society. Exorcism was the treatment generally applied to demoniacs and seems to have caused some alleviation in the suffering of mentally distressed people. We have selected and analyzed some cases of demonic possession from thirteenth-century hagiographical literature. In the description of demoniacs we have been able to find traits of psychotic, mood, neurotic, personality disorders and epilepsy. The exorcisms analyzed in our article are the result of literary invention more than the description of a contemporary event. Nevertheless, the writers were witnesses of their time, transferred their knowledge about exorcism and possession in their narrative and presumably incorporated their actual experience with demoniacs.

    The past two decades have witnessed a plethora of studies on the medieval monster. These studies have contributed significantly to our understanding of religion, art, literature, and science in the Middle Ages. However, a tendency to treat the medieval monster in purely symbolic and psychological terms ignores the lived experiences of impaired medieval people and their culture's attitudes toward them. With the aid of recent insights provided by disability studies, this article aims to confront "real" medieval monsters--e.g., physically impaired human beings--in both their human and monstrous aspects.

    2001-12-01

    We have been interested in the cleansing capacity of skin during the recent years. In a paper of ours (1) we presented a few references to Hippocrates' and Galen's ideas on the subject, while the main body of the article was based on the 17th-20th centuries' relative practices. In a second paper (2), we were mainly testing the ancient and Medieval Greek ideas on skin catharsis against some clinical work of ours. In this paper we now present the ideas of the pagan and Byzantine Greek authors (5th cent. BC - 10th cent. AD) on the relationship of the human body to the natural and man-made world. Special emphasis is given to the relationship between purification through the skin and world purification. Based on the similarity of the Empedokles' concept of the four elements and Hippocrates' thesis concerning the four humours, the Earth itself was personified and became a living organism that felt cold, perspired and became dry. Man started to seek a natural explanation for his diseases and alterations of his body functions. Hence, perspiration, fever, urination, headache, stroke, were explained in cosmological terms. Extracts from many medical and non-medical writers, like Empedocles, Hippocrates, Aristotle, Galen, the Fathers of the Church, Meletius latrosophista, Theophilus Protospatharius, Michael Psellus and other sources are presented, in order to show the close relationship between an abundance of diseases and an array of natural phenomena.

They relied heavily on a partial Latin translation of PLATO's Timaeus by Chalcidius (4th century AD), and on a series of encyclopedic treatises associated with the names of Pliny the Elder (ca AD 23-79), Seneca (4 BC-AD 65), Macrobius (fl 5th century AD), Martianus ...

    Psychosomatic sympton of the sinful human soul, progress of natural and progressive wear of the psychic or corporeal machinery, exclusive property of the world of bodies or place of the obligatory link between the intellect and the body, fatigue crosses the philosophical and theological medieval literature. The various treatments of fatigue can, in their turn, serve as symptoms to differentiate the medieval anthropologies. This article presents four of their figures: the anthropology of danger elaborated by Augustin, Greek and Arabe medical diagnosis which is passed on the XIth century, and the readings of Aristotle's psychology by Albert the Great and Thomas Aquinas in the XIIIth century.

    Medieval medicine is not much interested in natural philosophy. Nevertheless, it is based upon clear methodological and epistemological principles, where the word 'nature' is used in several ways. The natural 'virtues' of things--including magical ones--are most important for therapy. Human health is influenced by stars (planets, zodiac) and seasons, and the physician has to take into account such cosmic effects. The chances of healing depend on the patients' 'nature' in relation to the power of illness. A strong nature makes medicine superfluous, an overwhelming disease cannot be beaten. Thus, medicine is limited to 'neutral' situations when supporting the patient makes his 'nature' win.

    2011-01-01

    The medical writings of early medieval western Europe c. 700 – c. 1000 have often been derided for their disorganised appearance, poor Latin, nebulous conceptual framework, admixtures of magic and folklore, and general lack of those positive features that historians attribute to ancient or later medieval medicine. This paper attempts to rescue the period from its negative image. It examines a number of superficially bizarre writings so as to place them in an intellectual and sociological context, and to suggest that the presumed contrast between them and their ancient and later medieval counterparts has been wrongly drawn.

    2009-08-01

    Medieval Islamic scholars wrote a great number of books on the qibla, the Sacred Direction. These books had a huge readership and provided instructions for finding the direction of Mecca by either exact or approximate means. In principle, the qibla was a purely religious subject, but in practice its determination required the use of astronomy as an applied science. As so often, religion and politics had many points of contact and, in this case, it was generally political considerations that prevailed. Finally, the analysis of nautical charts can offer new perspectives. As yet, modern scholarship has not established the link between this area of study and the classical literature on this subject.

    In 2008, after 13 years of preparation, the Generalitat of Catalunya finished the publication of the 10 volumes of the Dietaris de la Generalitat de Catalunya. The Dietaris, as well as a closely related source, the llibre de Jornades 1411/1484 de Jaume Safont, cover the period of 1411 to 1539. In this article, we examine astronomical references contained in these two sources, and place them in their historical context. Our main focus lies on astronomical phenomena that have not previously been published in the astronomical literature. In fact, relatively few astronomical records are accessible in Spanish medieval and early modern history, and our paper intends to fill this gap partially.

  2. THE ORIGIN OF THE CONCEPT OF NEUROPATHIC PAIN IN EARLY MEDIEVAL PERSIA (9TH-12TH CENTURY CE).

    Neuropathic pain is supposed to be a post-renaissance described medical entity. Although it is often believed that John Fothergill (1712-1780) provided the first description of this condition in 1773, a review of the medieval Persian medical writings will show the fact that neuropathic pain was a medieval-originated concept. "Auojae Asab" [Nerve-originated Pain] was used as a medical term in medieval Persian medical literature for pain syndromes which etiologically originated from nerves. Physicians like Rhazes (d. 925 CE), Haly Abbas (d. 982 CE), Avicenna (d. 1037 CE), and Jorjani (d. 1137 CE) have discussed multiple aspects of nerve-originated pain including its classification, etiology, differentiating characteristics, different qualities, and pharmacologic and non-pharmacologic treatments. Recognizing medieval scholars' views on nerve-originated pain can lighten old historical origins of this concept.

    In Dantean cosmography the Universe is described as a series of concentric spheres with all the known planets embedded in their rotation motion, the Earth located at the centre and Lucifer at the centre of the Earth. Beyond these "celestial spheres", Dante represents the "angelic choirs" as other nine spheres surrounding God. The rotation velocity increases with decreasing distance from God, that is with increasing Power (Virtù). We show that, adding Power as an additional fourth dimension to space, the modern equations governing the expansion of a closed Universe (i.e. with the density parameter Ω0 > 1) in the space-time, can be applied to the medieval Universe as imaged by Dante in his Divine Comedy. In this representation, the Cosmos acquires a unique description and Lucifer is not located at the centre of the hyperspheres.

    Melk Abbey, a marvel of European high baroque architecture, is one of the most frequently visited tourist attractions in Austria, attracting 450 000 visitors each year. The monastery's museum presents selected aspects of Benedictine life in Melk since the monastery's foundation in 1089. After the church, the library is the second-most important room in a Benedictine monastery. Due to the wide scientific interests and contacts of the medieval monks, these libraries also contain manuscripts on mathematics, physics and astronomy. In 2009, the International Year of Astronomy (IYA2009), the annual library exhibition was fully dedicated to astronomical manuscripts and early prints from the past 1000 years. Following earlier research work on astronomical manuscripts in Melk's library, we were invited to organise the exhibition. In addition, we also presented a lecture series and provided more background in an accompanying book. Because of positive feedback from the visitors, the exhibition was extended until March 2011. In the two years of its duration, the exhibition was seen by more than 900 000 visitors. In this article, we describe the background to the scientific project, how the exhibition was organised and lessons learned from this project.

  6. Evidence that the Vinland Map is medieval.

    2003-12-01

    The Vinland Map has been proposed to date to the mid-fifteenth century and is significant in showing the north Atlantic area of what is now North America about 50 years before the voyages of Columbus. It has been confirmed by radiocarbon dating that the map was drawn on a fifteenth century parchment; however, controversy regarding the ink of the map has persisted. Analytical studies of the ink of the map have been interpreted to show that the map is a twentieth century forgery because of the presence of carbon and anatase in the ink. However, carbon is known to have been added to medieval iron gallotannate inks, and the presence of anatase in a medieval ink can be explained by examining the process of making medieval inks.

    Islamic scholars of the Middle Ages are often credited with preserving the scientific writings of Antiquity through the Dark Ages of Europe. Saliba argues that the medieval Islamic astronomers did far more—actually correcting and improving on Greek astronomy by creating new mathematical tools to explain the motions of celestial objects. These tools were so useful that Copernicus appears to have borrowed them for use in his heliocentric cosmology. In this new light, the medieval Islamic astronomers played a fundamental role in the scientific revolution that was forged in Europe during the Renaissance.

  8. Sex Differentials in Frailty in Medieval England

    In most modern populations, there are sex differentials in morbidity and mortality that favor women. This study addresses whether such female advantages existed to any appreciable degree in medieval Europe. The analyses presented here examine whether men and women with osteological stress markers faced the same risks of death in medieval London. The sample used for this study comes from the East Smithfield Black Death cemetery in London. The benefit of using this cemetery is that most, if not all, individuals interred in East Smithfield died from the same cause within a very short period of time. This allows for the analysis of the differences between men and women in the risks of mortality associated with osteological stress markers without the potential confounding effects of different causes of death. A sample of 299 adults (173 males, 126 females) from the East Smithfield cemetery was analyzed. The results indicate that the excess mortality associated with several osteological stress markers was higher for men than for women. This suggests that in this medieval population, previous physiological stress increased the risk of death for men during the Black Death to a greater extent than was true for women. Alternatively, the results might indicate that the Black Death discriminated less strongly between women with and without pre-existing health conditions than was true for men. These results are examined in light of previous analyses of East Smithfield and what is known about diet and sexually-mediated access to resources in medieval England. PMID:20853482

    Paris, Harry S.; Amar, Zohar; Lev, Efraim

    2012-01-01

    Background Sweet melons, Cucumis melo, are a widely grown and highly prized crop. While melons were familiar in antiquity, they were grown mostly for use of the young fruits, which are similar in appearance and taste to cucumbers, C. sativus. The time and place of emergence of sweet melons is obscure, but they are generally thought to have reached Europe from the east near the end of the 15th century. The objective of the present work was to determine where and when truly sweet melons were first developed. Methods Given their large size and sweetness, melons are often confounded with watermelons, Citrullus lanatus, so a list was prepared of the characteristics distinguishing between them. An extensive search of literature from the Roman and medieval periods was conducted and the findings were considered in their context against this list and particularly in regard to the use of the word ‘melon’ and of adjectives for sweetness and colour. Findings Medieval lexicographies and an illustrated Arabic translation of Dioscorides' herbal suggest that sweet melons were present in Central Asia in the mid-9th century. A travelogue description indicates the presence of sweet melons in Khorasan and Persia by the mid-10th century. Agricultural literature from Andalusia documents the growing of sweet melons, evidently casabas (Inodorous Group), there by the second half of the 11th century, which probably arrived from Central Asia as a consequence of Islamic conquest, trade and agricultural development. Climate and geopolitical boundaries were the likely causes of the delay in the spread of sweet melons into the rest of Europe. PMID:22648880

    In order to study the special composition of animals used in the medieval medicine of Azerbaijan, a wide range of medieval sources on medicine and pharmacognosy from the collection of the Institute of Manuscripts of the Azerbaijan Academy of Sciences in Baku has been studied. About 40 medieval sources from the 10-18th centuries including 17 manuscripts in Turkic, Persian and Arabic have been selected as the objects of this study. As a result, 150 species of animals described in medieval Azerbaijani books on medicine and pharmacy have been identified. Many of the identified animals are mammals, (47 species or 31% of total number of identified species). The medieval authors describe 12 species of reptiles and 4 species of Amphibians (frogs, toads, salamanders and tree-frogs (Hyla arborea). 15 species of fishes described in medieval manuscripts have been identified. The identified molluscs are cuttlefish (Sepia officinalis), mussel (Mytilus edulis), octopus (Octopus vulgaris) and snail (Helix pomatia). Most crustaceans used in medieval Azerbaijan medicine belong to Decopoda. Medieval manuscripts contain numerous names of various worms and insects (ants, flies, beetles, etc.), however their exact identification is rather difficult. As usual, medieval authors unite a number of species under one name and do not give sufficient information about their morphology. Results of the research create grounds for the idea that the recommendations of the medieval authors on the medicinal application of animals can be applied to modern medicine once they have been experimentally and clinically tested.

    Tremor has been described in traditional systems of medicine throughout history. Persian medicine was one of those systems in medieval times and in it neurology and neurosurgery were also widely practiced and accepted. Based on the main Persian medical manuscripts, the current study focuses on the medieval concept of tremor as an important neurological disorder in order to clarify the development of neurology. Accordingly, three main approaches to the control and treatment of tremor in traditional Persian medicine are considered. First is lifestyle modification. The administration of simple medicines is the second, and the last is the application of compound medicines. Our study shows how much was known about tremor in traditional Persian medicine.

    When Trondheim celebrated its millenium in 1997, this also marked a 1000 year-old medical tradition. In medieval times, sick and disabled people made their pilgrimage to the Nidaros cathedral and the grave of Saint Olav (995-1030). Working from the assumption that every organized society develops rituals and rules to deal with disease and death, we have looked for evidence of what kind of healers one would expect there were in medieval Trondheim up to the reformation in 1537. Sources include reports from archaeological excavations, written material of both medieval and more recent origin, buildings and objects, and living traditions. Three kinds of healer traditions can be identified: The popular and "wise" folk healers were based on traditional pre-Christian mythology and belief in natural forces. The charitable clerics emerged with Christianity. The "professional" wound healers evolved from the needs of the military, later to merge with the early barber surgeons. Traces of scientific traditions, the Salerno school and early European university medicine can be found in local texts, but there is no evidence of any university educated doctor practising in Trondheim before the 17th century.

    A review of the literature shows that origination of biological stones as well as their pathogenesis mostly depend on the environmental factors. As a result, the structural spectrum of such calculi and their chemical composition are highly diversified. It is well known that biological stones are formed mostly in the digestive and urinary tracts. However, it has been demonstrated that this kind of stony structure can be also, though rarely, found in circulatory and reproductive systems, skin, mucosa, and tear ducts. Although in palaeopathology, the list of biological stones is enriched by stony tumours and/or discharges, it is very difficult to uncover the small size deposits in excavation material. In the literature such findings, originating from different countries and centuries, are few. The described stone was found among the bones of an adult individual in the medieval cemetery of Gdańsk (Poland). The SEM, X-ray spectrometer and chemical evaluation revealed that it was a bladder calculus. PMID:25275551

  18. Medieval European medicine and Asian spices.

    PubMed

    Nam, Jong Kuk

    2014-08-01

    This article aimed to explain the reasons why Asian spices including pepper, ginger, and cinnamon were considered as special and valuable drugs with curative powers in the Medieval Europe. Among these spices, pepper was most widely and frequently used as medicine according to medieval medical textbooks. We analyzed three main pharmacology books written during the Middle Ages. One of the main reasons that oriental spices were widely used as medicine was due to the particular medieval medical system fundamentally based on the humoral theory invented by Hippocrates and Galen. This theory was modified by Arab physicians and imported to Europe during the Middle Ages. According to this theory, health is determined by the balance of the following four humors which compose the human body: blood, yellow bile, black bile, and phlegm. Each humor has its own qualities such as cold, hot, wet, and dry. Humoral imbalance was one of the main causes of disease, so it was important to have humoral equilibrium. Asian spices with hot and dry qualities were used to balance the cold and wet European diet. The analysis of several major medical textbooks of the Middle Ages proves that most of the oriental spices with hot and dry qualities were employed to cure diverse diseases, particularly those caused by coldness and humidity. However, it should be noted that the oriental spices were considered to be much more valuable and effective as medicines than the local medicinal ingredients, which were not only easily procured but also were relatively cheap. Europeans mystified oriental spices, with the belief that they have marvelous and mysterious healing powers. Such mystification was related to the terrestrial Paradise.

  19. Medieval European medicine and Asian spices.

    This article aimed to explain the reasons why Asian spices including pepper, ginger, and cinnamon were considered as special and valuable drugs with curative powers in the Medieval Europe. Among these spices, pepper was most widely and frequently used as medicine according to medieval medical textbooks. We analyzed three main pharmacology books written during the Middle Ages. One of the main reasons that oriental spices were widely used as medicine was due to the particular medieval medical system fundamentally based on the humoral theory invented by Hippocrates and Galen. This theory was modified by Arab physicians and imported to Europe during the Middle Ages. According to this theory, health is determined by the balance of the following four humors which compose the human body: blood, yellow bile, black bile, and phlegm. Each humor has its own qualities such as cold, hot, wet, and dry. Humoral imbalance was one of the main causes of disease, so it was important to have humoral equilibrium. Asian spices with hot and dry qualities were used to balance the cold and wet European diet. The analysis of several major medical textbooks of the Middle Ages proves that most of the oriental spices with hot and dry qualities were employed to cure diverse diseases, particularly those caused by coldness and humidity. However, it should be noted that the oriental spices were considered to be much more valuable and effective as medicines than the local medicinal ingredients, which were not only easily procured but also were relatively cheap. Europeans mystified oriental spices, with the belief that they have marvelous and mysterious healing powers. Such mystification was related to the terrestrial Paradise.

    Kashmir has the peculiarity of having written history of almost 5,000 years. However, the description of earthquakes in the archival contents is patchy prior to 1500 a.d. Moreover, recent search shows that there exist certain time gaps in the catalogs presently in use especially at medieval level (1128-1586 a.d.). The presence of different ruling elites in association with socioeconomic and political conditions has in many ways confused the historical context of the medieval sources. However, by a meticulous review of the Sanskrit sources (between the twelfth and sixteenth century), it has been possible to identify unspecified but fair number (eight seismic events) of earthquakes that do not exist in published catalogs of Kashmir or whose dates are very difficult to establish. Moreover, historical sources reveal that except for events which occurred during Sultan Skinder's rule (1389-1413) and during the reign of King Zain-ul-Abidin (1420-1470), all the rediscovered seismic events went into oblivion, due mainly to the fact that the sources available dedicated their interests to the military events, which often tended to overshadow/superimpose over and even concealed natural events like earthquakes, resulting in fragmentary accounts and rendering them of little value for macroseismic intensity evaluation necessary for more efficient seismic hazard assessment.

  2. Views on sexuality in croatian medieval sources.

    We analyzed attitudes towards sexuality during the medieval period in Croatia. For that purpose we investigated numerous medical and literary texts, statutes, and specific natural philosophical work entitled "Lucidar". Contrary to medical books, which had a low impact on the broader community, literary texts were important in spreading messages on sexuality, as well as in shaping medieval mentality and creating sexual taboos. Consequently, a specific perspective and culture influenced rules and practices for community protection, as well as various levels of social systems. Within the three large groups of sources, we selected those typical both in their content (ideas) and forms, and representative in shaping attitudes toward sexuality on our territory. The first group of sources (examples from literary genres) were identified as an important vehicle in transferring messages of morality, moral obligation and sexuality in general. Deeply rooted in Christianity they became a pattern according to which the way of life and value were measured, a specific view toward sexuality was shaped, and notions of stigma and taboo articulated.

    Medieval cosmology was a fusion of pagan Greek ideas and biblical descriptions of the world, especially the creation account in Genesis. Planets, Stars, and Orbs describes medieval conceptions of the cosmos as understood by scholastic theologians and natural philosophers in the universities of western Europe from the thirteenth to the seventeenth centuries. Not only are the major ideas and arguments of medieval cosmology described and analysed, but much attention is paid to the responses of scholastic natural philosophers of the sixteenth and seventeenth centuries to the challenges posed by the new science and astronomy as represented by Copernicus, Tycho Brahe, Galileo and Kepler.

    2013-01-01

    Background and Aims The watermelon, Citrullus lanatus (Cucurbitaceae), is an important fruit vegetable in the warmer regions of the world. Watermelons were illustrated in Mediterranean Antiquity, but not as frequently as some other cucurbits. Little is known concerning the watermelons of Mediterranean Europe during medieval times. With the objective of obtaining an improved understanding of watermelon history and diversity in this region, medieval drawings purportedly of watermelons were collected, examined and compared for originality, detail and accuracy. Findings The oldest manuscript found that contains an accurate, informative image of watermelon is the Tractatus de herbis, British Library ms. Egerton 747, which was produced in southern Italy, around the year 1300. A dozen more original illustrations were found, most of them from Italy, produced during the ensuing two centuries that can be positively identified as watermelon. In most herbal-type manuscripts, the foliage is depicted realistically, the plants shown as having long internodes, alternate leaves with pinnatifid leaf laminae, and the fruits are small, round and striped. The manuscript that contains the most detailed and accurate image of watermelon is the Carrara Herbal, British Library ms. Egerton 2020. In the agriculture-based manuscripts, the foliage, if depicted, is not accurate, but variation in the size, shape and coloration of the fruits is evident. Both red-flesh and white-flesh watermelons are illustrated, corresponding to the typical sweet dessert watermelons so common today and the insipid citron watermelons, respectively. The variation in watermelon fruit size, shape and coloration depicted in the illustrations indicates that at least six cultivars of watermelon are represented, three of which probably had red, sweet flesh and three of which appear to have been citrons. Evidently, citron watermelons were more common in Mediterranean Europe in the past than they are today. PMID:23904443

    Tooth wear is a natural phenomenon and a universal occurrence that has existed from the origin of humankind and depends on the way of life, especially diet. Tooth wear was very serious in ancient populations up to the medieval period. The aim of this paper is to present a global view of tooth wear in medieval times in Europe through different parameters: scoring systems, quantity and direction of wear, gender, differences between maxilla and mandible, relations with diet, caries, tooth malpositions and age.

    Various minerals, metals, clays, and rocks were among the natural medicinal substances used by physicians and pharmacists in early times in different cultures, for example, the ancient civilizations of Egypt and Mesopotamia. Classical physicians such as Hippocrates and Dioscorides mention tens of inorganic medicinal substances in their writings. Many references to minerals and chemicals are also found in the Muslim medical literature of the Eastern and Western Caliphates. The historical research presented in this article focuses on the inorganic substances applied as remedies by the medieval and early Ottoman (7th-17th) inhabitants of the Levant. The article is based upon a literature review covering tens of different historical sources, from the medieval and early Ottoman periods. Relevant information was found in the works of physicians such as al-Tamimi, Benevenutus, Ibn al-Baytar, Daud al-Antaki, and Hayyim Vital. The research revealed evidences of the medicinal uses of fifteen inorganic substances: Alum, Arsenic, Sulphide, Asphalt, Jew's stone, Earth sp., Galena, Haematite, iron, Lead, Pyrite, Salt, Sulphur, Thermal water, Green Vitriol, and Zinc. Inorganic materials comprise 5.2% of the list of medicinal substances. The geographic origin of most of these substances is the Levant, in which two geo-historical centers have been recorded: the Rift Valley and the northern region of the Levant, including upper Galilee, Mount Lebanon and Mount Hermon. A notable tendency to use these substances for treating diseases of the skin, the eyes, the sexual organs, and haemorrhoids was detected. PMID:20329348

    National monuments are at ever-increasing risk of severe and permanent damage. The 3D laser scanning of stone monuments brings a new dimension in the field of cultural heritage by providing means of preserving, visualizing, accessing and analysing some of its most invaluable artefacts. In this article, we present the results obtained with our project "Profilometry of Medieval Irish Stone Monuments" hosted at the Centre for the Study of Human Settlement and Historical Change, NUI Galway. This project aims to create a virtual archive of selected incised stones from 3D scans taken in the field. The raw scans are processed into watertight 3D models and new processing techniques have been developed to enhance the surface features of the stones. Also, textured 3D models of the artefacts have been made available online for the benefit of both the historian community and the broader public. This article focuses on the analysis we performed on the shaft of the east cross at Toureen Peacaun, Co Tipperary, which shows the longest inscription in Ireland with geometrical capitals.

  11. Mechanisms Underlying Early Medieval Droughts in Mesoamerica

    2015-12-01

    Multidecadal drought during the early Medieval Climate Anomaly (MCA, 800-1200 CE) in Mesoamerica has been implicated in the demise of many pre-Columbian societies, including the Maya. The mechanisms behind these droughts, however, are poorly understood. Researchers most often interpret these records as tracking the mean position of the ITCZ, with a southward shifted ITCZ resulting in Mesoamerican drought. This is puzzling, however, because our dynamical understanding of the ITCZ and its role in interhemispheric heat transport would suggest a more northward shifted ITCZ during the MCA. Here, we evaluate two hypotheses to reconcile existing proxies and dynamics. First, we assess whether evidence for dry conditions during the MCA is robust across multiple Mesoamerican proxy records, focusing on the influence of radiometric dating uncertainty on estimates of drought timing. Second, we use control simulations of CCSM4 and HadCM3, as well as a broader synthesis of oceanic and terrestrial proxies, to explore the mechanisms responsible for long-term drought in Mesoamerica. Ultimately, we suggest that a temporary slowdown of the AMOC, either internally or externally forced, combined with local and regional land surface feedbacks can explain these droughts in Mesoamerica.

  12. Representations of Lancet or Phlebotome in Serbian Medieval Art.

    2015-01-01

    The topic of this study are representations of lancet or phlebotome in frescoes and icons of Serbian medieval art. The very presence of this medical instrument in Serbian medieval art indicates its usage in Serbian medical practices of the time. Phlebotomy is one of the oldest forms of therapy, widely spread in medieval times. It is also mentioned in Serbian medical texts, such as Chilandar Medical CodexNo. 517 and Hodoch code, i.e. translations from Latin texts originating from Salerno-Montpellier school. Lancet or phlebotome is identified based on archaeological finds from the Roman period, while finds from the Middle Ages and especially from Byzantium have been scarce. Analyses of preserved frescoes and icons has shown that, in comparison to other medical instruments, lancet is indeed predominant in Serbian medieval art, and that it makes for over 80% of all the representations, while other instruments have been depicted to a far lesser degree. Examination of written records and art points to the conclusion that Serbian medieval medicine, both in theory and in practice, belonged entirely to European traditions of the period. PMID:26727878

    The roots of spine biomechanics reside in the Antiquity and the Medieval and Renaissance periods. A review of historical treatises reveals detailed information regarding this often historically neglected discipline. Ancient medical, philosophical, and physical documents were reviewed, as they pertained to the historical foundation of spine biomechanics. These included medical case reports and observations of nature and motion by ancient philosophers and scientists. These documents heavily influenced the portion of the scientific literature that we now regard as "spine biomechanics" up through the Renaissance. The focus of Part I of this two-part series is placed on the ancient and medieval biomechanics-related literature and on associated literature that influenced the development of the field of modern spine biomechanics.

  14. Women performers and prostitutes in Medieval India.

    2012-01-01

    Music and dance, the esoteric performing arts, were markers of culture in medieval India. A number of these differing forms developed into well-recognized and reputed arts over time. The practitioners were, accordingly, regarded as agents of refinement and culture. At the same time, music and dance were also among the most popular forms of entertainment and physical pleasure. This aspect remained crucial in classifying musicians, singers and dancers as entertainers, alongside prostitutes. While the labelling together might have reduced the status of performers at times, the labelling hardly remained fixed. Certain practitioners, even if involved in practices otherwise considered immoral, could remain within the elite circle, while for others the ‘evil’ characteristics got emphasized. There were, within the class of women who prostituted themselves, courtesans trained in the skills of music and dancing and educated in the fine arts, who were treated more as embodiments of culture. These categories—artists, skilled entertainers, courtesans—were quite fluid, with the boundaries seemingly fused together. Still, there were certainly some distinctions among the categories and those did not totally disappear, affording sanctity and purity to certain kinds of performers and allowing them to claim distinctiveness. Notably, the class of courtesans clearly stood apart from the common prostitutes. The attempt in this article is to look at different categories of women performers and prostitutes, their apparent coalescing boundaries and specialities as a separate group, their societal position, their shifting roles and the changes that affected their status. In this, it is worthwhile to consider the state’s attitude towards them, besides societal views that remained quite diverse.

  15. Medieval monastic mortality: hazard analysis of mortality differences between monastic and nonmonastic cemeteries in England.

    PubMed

    DeWitte, Sharon N; Boulware, Jessica C; Redfern, Rebecca C

    2013-11-01

    Scholarship on life in medieval European monasteries has revealed a variety of factors that potentially affected mortality in these communities. Though there is some evidence based on age-at-death distributions from England that monastic males lived longer than members of the general public, what is missing from the literature is an explicit examination of how the risks of mortality within medieval monastic settings differed from those within contemporaneous lay populations. This study examines differences in the hazard of mortality for adult males between monastic cemeteries (n = 528) and non-monastic cemeteries (n = 368) from London, all of which date to between AD 1050 and 1540. Age-at-death data from all cemeteries are pooled to estimate the Gompertz hazard of mortality, and "monastic" (i.e., buried in a monastic cemetery) is modeled as a covariate affecting this baseline hazard. The estimated effect of the monastic covariate is negative, suggesting that individuals in the monastic communities faced reduced risks of dying compared to their peers in the lay communities. These results suggest better diets, the positive health benefits of religious behavior, better living conditions in general in monasteries, or selective recruitment of healthy or higher socioeconomic status individuals.

  16. Graeco-Roman case histories and their influence on Medieval Islamic clinical accounts.

    PubMed

    Alvarez Millan, C

    1999-04-01

    The medieval Islamic medical tradition was the direct heir of Classical and Hellenistic medicine thanks to an unprecedented movement of translation into Arabic, commentaries and systematizations of Greek scientific texts. In the process of assimilation, not only theoretical principles, but also literary models of presenting medical knowledge were adopted, amongst them the case history. Since the clinical account can be used as a tool for medical instruction as well as an instrument for professional self-promotion, this study seeks to investigate which purpose most motivated Islamic physicians, and to demonstrate the extent to which they were influenced by the stylistic patterns which served them as a model. This article comprises an analysis of the context, literary devices and purpose of case histories of the Epidemics, Rufus of Ephesos and Galen, and compares them with those by the tenth-century Islamic physician Abu Bakr Muhammad b. Zakariya al-Razi. Author of the largest number of case histories preserved within the medieval Islamic medical literature, al-Razi's clinical records constitute an instrument with which to study and expand medical knowledge as well as providing useful material for students' medical training. Although al-Razi fused elements from the sources which served him as a model, he did not emulate Galen's use of the clinical history to assert himself in order to gain authority and prestige, but remained faithful to the Hippocratic essence.

Medieval Islamic clinicians extended the Greco-Roman ideas with substantial contributions to the field of surgery, including tracheostomy. Although Al-Zahrawi (936-1013 CE) stated that he had not heard or read of any Islamic physicians having performed tracheostomy, there is evidence that many prominent Islamic surgeons did practice this lifesaving procedure during medieval times. Throughout the Islamic Golden Age, Muslim physicians advanced the practice of tracheostomy with many modifications of the procedure, instrumentation, and adjuvant medicinal prescriptions.

    Lesions consistent with skeletal tuberculosis were found in 13 individuals from an early medieval skeletal sample from Courroux (Switzerland). One case of Pott's disease as well as lytic lesions in vertebrae and joints, rib lesions and endocranial new bone formation were identified. Three individuals with lesions and one without were tested for the presence of Myobacterium tuberculosis complex (MTBC) ancient DNA (aDNA), and in two cases, evidence for MTBC aDNA was detected. Our results suggest the presence of tuberculosis in the analysed material, which is in accordance with other osteological and biomolecular research that reported a high prevalence of tuberculosis in medieval skeletons.

  1. Saving the Phenomena in Medieval Astronomy

    NASA Astrophysics Data System (ADS)

    Seeskin, K.

    2011-06-01

    Aristotle's theory of motion is based on two principles: (1) all motion to either from the midpoint of the Earth, toward it, or around it, and (2) circular motion must proceed around an immovable point. On this view, the heavenly bodies are individual points of light carried around by a series of concentric spheres rotating at a constant pace around the midpoint of the Earth. But even in Aristotle's day, it was known that this theory had a great deal of difficulty accounting for planetary motion. Ptolemy's alternative was to introduce epicycles and eccentric orbits, thus denying Aristotle's view of natural motion. There was no doubt that Ptolemy's predictions were far better than Aristotle's. But for the medievals, Aristotle's theory made better intuitive sense. Moreover, Ptolemy's theory raised the question of how one sphere could pass through another. What to do? The solution of Moses Maimonides (1138-1204) was to say that it is not the job of the astronomer to tell us how things actually are but merely to propose a series of hypotheses that allow us to explain the relevant data. This view had obvious theological implications. If astronomy could explain planetary motion in an acceptable way, there was reason to believe that the order or structure of the heavens is what it is by necessity. This suggests that God did not exercise any degree of choice in making it that way. But if astronomy cannot explain planetary motion, the most reasonable explanation is that we are dealing with contingent phenomena rather than necessary ones. If there is contingency, there is reason to think God did exercise a degree of choice in making the heavens the way they are. A God who exercises choice is much closer to the God of Scripture. Although Galileo changed all of this, and paved the way for a vastly different view of astronomy, the answer to one set of questions raises a whole different set. In short, the heavenly motion still poses ultimate questions about God, existence, and

    Social representations in later medieval culture have attracted little attention amongst psychologists, pre-dating the development of the so-called 'public sphere' in the eighteenth century. In addition, the association of pre-modern societies with 'traditional' modes of communication in social psychology places implicit limits on areas that may be studied through the lens of social representation theory. This article analyses the way in which knowledge circulated in late medieval society, noting initially the plural nature of representations of events and marginal groups, and the myriad channels through which beliefs were consolidated. In later medieval England perceptions of the past depended on collective and group memory, with customary rights and local histories forged through 'common knowledge', hearsay and the opinions of 'trustworthy men' of the village. The final section of this commentary provides an analysis of testimony from the late medieval church courts, in which witnesses articulated gender ideologies that reflected perceptions drawn from everyday life. Social representations of women were thus deployed in ecclesiastical suits, on the one hand supporting evidence of female witnesses and on the other justifying misogynistic stereotypes of women's behaviour.

    In the period between 400 to 800 AD, also known as the period of the Barbarian invasions, intense migration is documented in the historical record of Europe. However, little is known about the demographic impact of these historical movements, potentially ranging from negligible to substantial. As a pilot study in a broader project on Medieval Europe, we sampled 102 specimens from 5 burial sites in Northwestern Italy, archaeologically classified as belonging to Lombards or Longobards, a Germanic people ruling over a vast section of the Italian peninsula from 568 to 774. We successfully amplified and typed the mitochondrial hypervariable region I (HVR-I) of 28 individuals. Comparisons of genetic diversity with other ancient populations and haplotype networks did not suggest that these samples are heterogeneous, and hence allowed us to jointly compare them with three isolated contemporary populations, and with a modern sample of a large city, representing a control for the effects of recent immigration. We then generated by serial coalescent simulations 16 millions of genealogies, contrasting a model of genealogical continuity with one in which the contemporary samples are genealogically independent from the medieval sample. Analyses by Approximate Bayesian Computation showed that the latter model fits the data in most cases, with one exception, Trino Vercellese, in which the evidence was compatible with persistence up to the present time of genetic features observed among this early medieval population. We conclude that it is possible, in general, to detect evidence of genealogical ties between medieval and specific modern populations. However, only seldom did mitochondrial DNA data allow us to reject with confidence either model tested, which indicates that broader analyses, based on larger assemblages of samples and genetic markers, are needed to understand in detail the effects of medieval migration.

  15. Cultural Trauma and Christian Identity in the Late Medieval Heroic Epic, The Siege of Jerusalem.

    PubMed

    DeMarco, Patricia A

    2015-01-01

    This essay examines scenes of violence in the late medieval poem The Siege of Jerusalem in order to reveal the ways in which trauma is used as the grounds upon which Christian/Jewish difference is established. In particular, I argue that this poem serves as an example of a widespread element in Christian chivalric identity, namely the need to manage the repetitive invocation of Christ's crucifixion (ritually repeated through liturgical and poetic invocation) as a means of asserting both the bodily and psychic integrity of the Christian subject in contrast to the violently abjected figure of the Jewish body. The failure of The Siege protagonist, Wespasian, to navigate the cultural trauma of the crucifixion is contrasted to the successful management of trauma by the martial hero, Tancred, in Tasso's epic, Gerusalemme Liberata, illustrating the range of imaginative possibilities for understanding trauma in pre-modern war literature.

    Leprosy was endemic in Europe until the Middle Ages. Using DNA array capture, we have obtained genome sequences of Mycobacterium leprae from skeletons of five medieval leprosy cases from the United Kingdom, Sweden, and Denmark. In one case, the DNA was so well preserved that full de novo assembly of the ancient bacterial genome could be achieved through shotgun sequencing alone. The ancient M. leprae sequences were compared with those of 11 modern strains, representing diverse genotypes and geographic origins. The comparisons revealed remarkable genomic conservation during the past 1000 years, a European origin for leprosy in the Americas, and the presence of an M. leprae genotype in medieval Europe now commonly associated with the Middle East. The exceptional preservation of M. leprae biomarkers, both DNA and mycolic acids, in ancient skeletons has major implications for palaeomicrobiology and human pathogen evolution.

    ABSTRACT Shotgun metagenomics provides a powerful assumption-free approach to the recovery of pathogen genomes from contemporary and historical material. We sequenced the metagenome of a calcified nodule from the skeleton of a 14th-century middle-aged male excavated from the medieval Sardinian settlement of Geridu. We obtained 6.5-fold coverage of a Brucella melitensis genome. Sequence reads from this genome showed signatures typical of ancient or aged DNA. Despite the relatively low coverage, we were able to use information from single-nucleotide polymorphisms to place the medieval pathogen genome within a clade of B. melitensis strains that included the well-studied Ether strain and two other recent Italian isolates. We confirmed this placement using information from deletions and IS711 insertions. We conclude that metagenomics stands ready to document past and present infections, shedding light on the emergence, evolution, and spread of microbial pathogens. PMID:25028426

    Interrogations and elections were two branches of Arabic judicial astrology made available in Latin translation to readers in western Europe from the twelfth century. Through an analysis of the theory and practice of interrogations and elections, including the writing of the Jewish astrologer Sahl b. Bishr, this essay considers the extent to which judicial astrology was practiced in the medieval west. Consideration is given to historical examples of interrogations and elections mostly from late medieval English manuscripts. These include the work of John Dunstaple (ca. 1390-1453), the musician and astrologer who is known have served at the court of John, duke of Bedford. On the basis of the relatively small number of surviving historical horoscopes, it is argued that the practice of interrogations and elections lagged behind the theory.

    Has the Antilles Subduction Zone produced thrust or outer-rise earthquakes east of Hispaniola? An affirmative answer is suggested by tiered evidence for overwash 120 km south of the Puerto Rico Trench. The evidence comes from Anegada, British Virgin Islands, 200 km east-northeast of San Juan, Puerto Rico. PREVIOUS FINDINGS* suggested that a medieval overwash event had greater geologic effects at Anegada than did a Lisbon(?) event, and that both events outrank recent storms. The medieval overwash, in AD 1200-1450, dislodged brain corals from a reef, moved them as much as 500 m across a shallow subtidal flat, and scattered them as solitary boulders as much as 1000 m inland. Gentler overwash in 1650-1800, called Lisbon(?) because it may represent the 1755 tsunami, laid down a sheet of sand and island-derived shells as much as 1500 m from the north shore. A recent hurricane of category 4 left no durable geologic record other than sandy fans within 40 m of the south shore. NEW FINDINGS reinforce the ranking medieval > Lisbon(?) > storm: (1) The medieval event washed ashore marine shells that the Lisbon(?) event did not. An articulated marine bivalve (Codakia orbicularis), probably deposited live, is part of an overwash fan 400 m inland from Windlass Bight. The shell dates to the same time window as the medieval coral boulders. Additional articulated Codakia shells and a conch shell adjoin the buried base of one of these coral boulders 1500 m south of the fringing reef from which the coral was probably derived. (2) Lisbon(?) overwash used breaches that the medieval event had cut through beach ridges of the north shore. The re-use is marked by sand: on the muddy floor of a partly filled breach, on an organic soil in another such breach, and on a pre-existing fan south of an area of beach-ridge dissection. The buried organic soil, inset into a old breach, is 500 m inland from an area, near Cow Wreck High Point, where young beach ridges may have been breached for the first

    Medieval European urbanization presents a line of continuity between earlier cities and modern European urban systems. Yet, many of the spatial, political and economic features of medieval European cities were particular to the Middle Ages, and subsequently changed over the Early Modern Period and Industrial Revolution. There is a long tradition of demographic studies estimating the population sizes of medieval European cities, and comparative analyses of these data have shed much light on the long-term evolution of urban systems. However, the next step—to systematically relate the population size of these cities to their spatial and socioeconomic characteristics—has seldom been taken. This raises a series of interesting questions, as both modern and ancient cities have been observed to obey area-population relationships predicted by settlement scaling theory. To address these questions, we analyze a new dataset for the settled area and population of 173 European cities from the early fourteenth century to determine the relationship between population and settled area. To interpret this data, we develop two related models that lead to differing predictions regarding the quantitative form of the population-area relationship, depending on the level of social mixing present in these cities. Our empirical estimates of model parameters show a strong densification of cities with city population size, consistent with patterns in contemporary cities. Although social life in medieval Europe was orchestrated by hierarchical institutions (e.g., guilds, church, municipal organizations), our results show no statistically significant influence of these institutions on agglomeration effects. The similarities between the empirical patterns of settlement relating area to population observed here support the hypothesis that cities throughout history share common principles of organization that self-consistently relate their socioeconomic networks to structured urban spaces.

  3. Erecting Sex: Hermaphrodites and the Medieval Science of Surgery.

    PubMed

    DeVun, Leah

    2015-01-01

    This essay focuses on "hermaphrodites" and the emerging profession of surgery in thirteenth- and fourteenth-century Europe. During this period, surgeons made novel claims about their authority to regulate sexual difference by surgically ''correcting" errant sexual anatomies. Their theories about sex, I argue, drew upon both ancient roots and contemporary conflicts to conceptualize sexual difference in ways that influenced Western Europe for centuries thereafter. I argue that a close examination of medieval surgical texts complicates orthodox narratives in the broader history of sex and sexuality: medieval theorists approached sex in sophisticated and varied manners that belie any simple opposition of modern and premodern paradigms. In addition, because surgical treatments of hermaphrodites in the Middle Ages prefigure in many ways the treatment of atypical sex (a condition now called, controversially, intersex or disorders/differences of sex development) in the modern world, I suggest that the writings of medieval surgeons have the potential to provide new perspectives on our current debates about surgery and sexual difference.

  4. Human Parasites in Medieval Europe: Lifestyle, Sanitation and Medical Treatment.

    Parasites have been infecting humans throughout our evolution. However, not all people suffered with the same species or to the same intensity throughout this time. Our changing way of life has altered the suitability of humans to infection by each type of parasite. This analysis focuses upon the evidence for parasites from archaeological excavations at medieval sites across Europe. Comparison between the patterns of infection in the medieval period allows us to see how changes in sanitation, herding animals, growing and fertilizing crops, the fishing industry, food preparation and migration all affected human susceptibility to different parasites. We go on to explore how ectoparasites may have spread infectious bacterial diseases, and also consider what medieval medical practitioners thought of parasites and how they tried to treat them. While modern research has shown the use of a toilet decreases the risk of contracting certain intestinal parasites, the evidence for past societies presented here suggests that the invention of latrines had no observable beneficial effects upon intestinal health. This may be because toilets were not sufficiently ubiquitous until the last century, or that the use of fresh human faeces for manuring crops still ensured those parasite species were easily able to reinfect the population.

    Leprosy was a well-recognized and dreaded disease in medieval Europe. The disease is reported to have reached Germany with the Roman invasion and it was present in Scandinavia in the first centuries AD. This paper estimates and analyzes the frequency of leprosy among adult people buried in one of five medieval cemeteries in the city of Schleswig. Seven different dichotomous osteological lesions indicative of leprosy were analyzed, and it was possible to score at least one of these conditions on 350 adult skeletons (aged 15 or older). The scores were transformed to a statistic indicating the likelihood that the person to whom the skeleton belonged suffered from leprosy. It was found that the frequency of leprosy in the five cemeteries varied between 9 and 44%. Four of the five cemeteries showed frequencies ranging from 35 and 44% and with no statistically significant differences among them. The fifth cemetery showed a significantly lower frequency of leprosy (9%). The distribution of female age at death does not appear to be affected by leprosy status. This means that females experienced a considerably elevated risk of dying once they had contracted leprosy as the disease usually has a mid-adulthood age of onset. In four of the five cemeteries males with leprosy died in higher ages than men without leprosy--in two of the cemeteries the difference was statistically significant. This indicates that leprosy usually added less to the risk of dying among men than among women in medieval Schleswig.

    2011-01-01

    This study explores how medical authorities in medieval Islamic society understood and analyzed Greek authorities on the differences between men and women and their mutual contributions to the process of reproduction. As this research illustrates, such thinkers' interpretations of sex differences did not form a consistent corpus, and were in fact complex and divergent, reflecting, and contributing to, the social and cultural constructs of gender taken up by European authors in the Middle Ages. While some scholars have argued for a "one sex" view of human beings in the medieval period, a close reading of Islamic medical authors shows that the plurality and complexity of ideas about sex differences and the acceptance of the flexibility of barriers between the sexes make it difficult to assume that the biological knowledge about sex differences formed a unitary ideological foundation for a system of gender hierarchy. It is clear, however, that whatever their differences, medieval Islamic discussions of sex differences implicitly or explicitly emphasized the inferiority of the female body.

    Despite the well-known history of hypertension research in the modern era, like many other cardiovascular concepts, main points in the medieval concept of this disease and its early management methods remain obscure. This article attempts to make a brief review on the medieval origin of the concept of this disease from the Hidayat of Al-Akhawayni (?-983 AD). This article has reviewed the chapter of "Fi al-Imtela" (About the Fullness) from the Hidβyat al-Muta'allimin fi al-Tibb (The Students' Handbook of Medicine) of Al-Akhawayni. The definition, symptoms and treatments presented for the Imtela are compared with the current knowledge on hypertension. Akhawayni believed that Imtela could result from the excessive amount of blood within the blood vessels. It can manifest with symptoms including the presence of a pulsus magnus, sleepiness, weakness, dyspnea, facial blushing, engorgement of the vessels, thick urine, vascular rupture, and hemorrhagic stroke. He also suggested some ways to manage al-Imtela'. These include recommendations of changes in lifestyle (staying away from anger and sexual intercourse) and dietary program for patients (avoiding the consumption of wine, meat, and pastries, reducing the volume of food in a meal, maintaining a low-energy diet and the dietary usage of spinach and vinegar). Al-Akhawayni's description of "Imtela," despite of its numerous differences with current knowledge of hypertension, can be considered as medieval origin of the concept of hypertension.

    Diabetes Mellitus is a common metabolic disorder presenting increased amounts of serum glucose and will cover 5.4% of population by year 2025. Accordingly, this review was performed to gather and discuss the stand points on diagnosis, pathophysiology, non-pharmacological therapy and drug management of diabetes this disorder as described in medieval Persian medicine. To this, reports on diabetes were collected and analyzed from selected medical and pharmaceutical textbooks of Traditional Persian Medicine. A search on databases as Pubmed, Sciencedirect, Scopus and Google scholar was also performed to reconfirm the Anti diabetic activities of reported herbs. The term, Ziabites, was used to describe what is now spoken as diabetes. It was reported that Ziabites, is highly associated with kidney function. Etiologically, Ziabites was characterized as kidney hot or cold dystemperament as well as diffusion of fluid from other organs such as liver and intestines into the kidneys. This disorder was categorized into main types as hot (Ziabites-e-har) and cold (Ziabites-e-barid) as well as sweet urine (Bole-e-shirin). Most medieval cite signs of Ziabites were remarked as unusual and excessive thirst, frequent urination and polydipsia. On the management, life style modification and observing the essential rules of prevention in Persian medicine as well as herbal therapy and special simple manipulations were recommended. Current investigation was done to clarify the knowledge of medieval scientists on diabetes and related interventions. Reported remedies which are based on centuries of experience might be of beneficial for- further studies to the management of diabetes. PMID:24741508

    Shotgun metagenomics provides a powerful assumption-free approach to the recovery of pathogen genomes from contemporary and historical material. We sequenced the metagenome of a calcified nodule from the skeleton of a 14th-century middle-aged male excavated from the medieval Sardinian settlement of Geridu. We obtained 6.5-fold coverage of a Brucella melitensis genome. Sequence reads from this genome showed signatures typical of ancient or aged DNA. Despite the relatively low coverage, we were able to use information from single-nucleotide polymorphisms to place the medieval pathogen genome within a clade of B. melitensis strains that included the well-studied Ether strain and two other recent Italian isolates. We confirmed this placement using information from deletions and IS711 insertions. We conclude that metagenomics stands ready to document past and present infections, shedding light on the emergence, evolution, and spread of microbial pathogens. Importance: Infectious diseases have shaped human populations and societies throughout history. The recovery of pathogen DNA sequences from human remains provides an opportunity to identify and characterize the causes of individual and epidemic infections. By sequencing DNA extracted from medieval human remains through shotgun metagenomics, without target-specific capture or amplification, we have obtained a draft genome sequence of an ~700-year-old Brucella melitensis strain. Using a variety of bioinformatic approaches, we have shown that this historical strain is most closely related to recent strains isolated from Italy, confirming the continuity of this zoonotic infection, and even a specific lineage, in the Mediterranean region over the centuries.

Historians of medicine have stressed the academic activities of medical masters as those of conciliation and explanation of authority. I will rather suggest that the explanation of classical authority was not the main aim of the medical masters but, in fact, its very construction. I would like to develop this possibility by analysing the nature of the approach to visual perception in academic medical circles at the end of the thirteenth century and the beginning of the fourteenth century.

    It appears that from medieval period onwards the subjects having practical application were given more importance than the philosophical and theoretical aspects. But the physicians were keen observes and new drugs and information were added and the effect of religion, astrology and other systems is also seen. While the womenfolk used to collect from the nearby forests, drugs that were useful for common ailments, some drugs were also imported from other countries. Specialization in certain diseases or practices was prevalent and the physicians enjoyed a high status and respect in the society. Several such other aspects are dealt with in this article.

    The finds of remains of useful plants in archaeological objects were drawing attention already in the last century. However, it was not until after the World War II, in relation with renovation of historical cores of the towns, when a separate branch of the botany--archaeobotany constituted. In the Czech Republic it was E. Opravil who was the first to become engaged in a systematic archaeobotanical research at the beginning of the 60's. All the vegetal remains--fruits and seeds on the first place as well as pollen grains from prehistoric times to the post-medieval period, are the subjects of archaeobotany. The medieval waste pits are the richest sources of the vegetal remains. They contain a lot of diasporas of cultural as well as wild plants. The remains of useful plants are an authentic document of the vegetal component of diet. Even though some vegetal species, such as for example garlic, onion or stalk-plants, about whose cultivation we are informed from literature, occur only seldom, there appeared also the species not mentioned in literature. All the basic cereals have been known in our country already since the early Middle Ages. Wheat (Triticum aestivum) and rye (Secale cereale), as well as millet (Panicum miliaceum) that, along with buckwheat (Fagopyrum esculentum), were replaced by potatoes in the modern times were the most important. Also leguminous plants were of great importance in the diet even though their charred seeds seldom preserved.

    The finds of remains of useful plants in archaeological objects were drawing attention already in the last century. However, it was not until after the World War II, in relation with renovation of historical cores of the towns, when a separate branch of the botany--archaeobotany constituted. In the Czech Republic it was E. Opravil who was the first to become engaged in a systematic archaeobotanical research at the beginning of the 60's. All the vegetal remains--fruits and seeds on the first place as well as pollen grains from prehistoric times to the post-medieval period, are the subjects of archaeobotany. The medieval waste pits are the richest sources of the vegetal remains. They contain a lot of diasporas of cultural as well as wild plants. The remains of useful plants are an authentic document of the vegetal component of diet. Even though some vegetal species, such as for example garlic, onion or stalk-plants, about whose cultivation we are informed from literature, occur only seldom, there appeared also the species not mentioned in literature. All the basic cereals have been known in our country already since the early Middle Ages. Wheat (Triticum aestivum) and rye (Secale cereale), as well as millet (Panicum miliaceum) that, along with buckwheat (Fagopyrum esculentum), were replaced by potatoes in the modern times were the most important. Also leguminous plants were of great importance in the diet even though their charred seeds seldom preserved. Remains of oil plants such as hemp (Cannabis sativa), flax (Linum usitatissimum) and poppy (Papaver somniferum) preserved well. It was successfully proved that cucumber (Cucumis sativus), among other numerous kinds of vegetables, was introduced by the Slavs already in the 8th century in Moravia and in the 9th century in Bohemia.

    Dryland closed basin lake systems are ideal natural laboratories for model-proxy evaluations of how climate change alters the regional water balance. We use an existing water balance and lake-evaporation model of the Walker Lake Basin, a 1600-year reconstruction of Walker Lake shoreline elevations, and fields from the 20th Century Reanalysis to provide the following insights: 1) The three major historical (post-Little Ice Age) droughts observed in the California-western Nevada region (the 1930s, 1987-1992, and 2012-2015) are comparable in magnitude to the severe droughts of the Medieval Climate Anomaly but not in duration; 2) The atmospheric circulation anomalies associated with these events include poleward deflections of storm tracks and reduced moisture transport into the region; 3) To produce the Medieval lowstands of Walker Lake, precipitation and circulation anomalies comparable to historical droughts must persist for a minimum of 50 years. These insights show how severe historical and ongoing droughts in this region are within the range of natural variability. The 2012-2015 drought is also shown to be exacerbated by recent positive temperature anomalies that may be outside of the range of natural variability. These results can help to improve future water resource planning for the western United States, where ongoing and future changes in climate leading to increased water scarcity will have significant negative impacts on socioeconomic and ecological systems.

    Berlin originated from the two twin cities Berlin and Cölln, which both were founded at the beginning of the 13th century. However the real date of their foundation as well as the origin of the first settlers is still unknown. On the Berlin site the historic city center is still visible in the Nikolaiviertel, but the medieval origin of Cölln disappeared almost completely. In 2007 a large scale excavation, which comprised an area of about 1700m(2) of the historical center of the St. Peters church, recovers the remains of Cölln's first citizens and span a period of 500 years of medieval population. Here we present the first genetic analysis of a fivefold children's burial from excavations in Berlin. The genetic data unveiled next to ancestry and eye color data also the kinship and the gender of the five individuals. Together with the archeological context the new gained information help to shed more light on the possible reasons for this burial.

    Morphological and ultrastructural data from archaeological human bones are scarce, particularly data that have been correlated with information on the preservation of molecules such as DNA. Here we examine the bone structure of macroscopically well-preserved medieval human skeletons by transmission electron microscopy and immunohistochemistry, and the quantity and quality of DNA extracted from these skeletons. DNA technology has been increasingly used for analyzing physical evidence in archaeological forensics; however, the isolation of ancient DNA is difficult since it is highly degraded, extraction yields are low and the co-extraction of PCR inhibitors is a problem. We adapted and optimised a method that is frequently used for isolating DNA from modern samples, Chelex(®) 100 (Bio-Rad) extraction, for isolating DNA from archaeological human bones and teeth. The isolated DNA was analysed by real-time PCR using primers targeting the sex determining region on the Y chromosome (SRY) and STR typing using the AmpFlSTR(®) Identifiler PCR Amplification kit. Our results clearly show the preservation of bone matrix in medieval bones and the presence of intact osteocytes with well preserved encapsulated nuclei. In addition, we show how effective Chelex(®) 100 is for isolating ancient DNA from archaeological bones and teeth. This optimised method is suitable for STR typing using kits aimed specifically at degraded and difficult DNA templates since amplicons of up to 250bp were successfully amplified.

    High-resolution manganese and iron K-edges XANES spectra were collected on several samples of archeological interest: prehistorical paintings and medieval glasses. XANES spectra were collected at the ID21 facility (ESRF, Grenoble, France) using a micro-beam device and at the 11-2 beamline (SSRL, Stanford, USA) using a submillimetric beam. The medieval glasses studied are from gothic glass windows from Normandy (XIVth century). The aim of this study is to help understand the chemical durability of these materials, exposed to weathering since the XIVth century. They are used as analogues of weathered glasses used to dump metallic wastes. These glasses show surficial enrichment in manganese, due to its oxidation from II (glass) to III/IV (surface), which precipitates as amorphous oxy-hydroxides. Similarly, iron is oxidized on the surface and forms ferrihydrite-type aggregates. The prehistorical paintings are from Lascaux and Ekain (Basque country). We choose in that study the black ones, rich in manganese to search for potential evidences of some 'savoir-faire' that the Paleolithic men could have used to realize their paint in rock art, as shown earlier for Fe-bearing pigments. A large number of highly valuable samples, micrometric scaled, were extracted from these frescoes and show large variation in the mineralogical nature of the black pigments used, from an amorphous psilomelane-type to a well-crystallized pyrolusite. Correlation with the crystals morphology helps understanding the know-how of these early artists.

    River response to strong earthquake shaking in mountainous terrain often entails the flushing of sediments delivered by widespread co-seismic landsliding. Detailed mass-balance studies following major earthquakes in China, Taiwan, and New Zealand suggest fluvial recovery times ranging from several years to decades. We report a detailed chronology of earthquake-induced valley fills in the Pokhara region of western-central Nepal, and demonstrate that rivers continue to adjust to several large medieval earthquakes to the present day, thus challenging the notion of transient fluvial response to seismic disturbance. The Pokhara valley features one of the largest and most extensively dated sedimentary records of earthquake-triggered sedimentation in the Himalayas, and independently augments paleo-seismological archives obtained mainly from fault trenches and historic documents. New radiocarbon dates from the catastrophically deposited Pokhara Formation document multiple phases of extremely high geomorphic activity between ˜700 and ˜1700 AD, preserved in thick sequences of alternating fluvial conglomerates, massive mud and silt beds, and cohesive debris-flow deposits. These dated fan-marginal slackwater sediments indicate pronounced sediment pulses in the wake of at least three large medieval earthquakes in ˜1100, 1255, and 1344 AD. We combine these dates with digital elevation models, geological maps, differential GPS data, and sediment logs to estimate the extent of these three pulses that are characterized by sedimentation rates of ˜200 mm yr-1 and peak rates as high as 1,000 mm yr-1. Some 5.5 to 9 km3 of material infilled the pre-existing topography, and is now prone to ongoing fluvial dissection along major canyons. Contemporary river incision into the Pokhara Formation is rapid (120-170 mm yr-1), triggering widespread bank erosion, channel changes, and very high sediment yields of the order of 103 to 105 t km-2 yr-1, that by far outweigh bedrock denudation rates

    In a period of compilation, original observations and expansion (900-1100 A.D.), Persians described new clinical manifestations of the diseases and expanded the earlier knowledge of materia medica. In the epoch of the Arabic language domination in the scientific literature of this period, advent of medical authors to write in Farsi shined in the Persian principalities. Akhawayani Bokhari was by far the most outstanding scholar of the time who wrote one of the earliest pandects of medicine of the period, the Hidayat al-Mutallimin fi al-Tibb (Learner's Guide to Medicine) in new Persian. The Hidayat is a relatively short and simplified digest of medicine at the time providing a glimpse of high level of medical education at the Samanid period (819-999). The present article is a translation of the sections of the Hidayat related to the pulse and its characters and conditions affecting the pulse in an attempt to increase our knowledge of the medicine, and particularly the pulse examination throughout the medieval era.

    The concept of life forms emerging from inanimate matter--spontaneous generation--was widely accepted until the nineteenth century. Several medieval Jewish scholars acknowledged this scientific theory in their philosophical and religious contemplations. Quite interestingly, it served to reinforce diverse, or even opposite, theological conclusions. One approach excluded spontaneously-generated living beings form the biblical account of creation or the story of the Deluge. Underlying this view is an understanding that organisms that generate spontaneously evolve continuously in nature and, therefore, do not require divine intervention in their formation or survival during disastrous events. This naturalistic position reduces the miraculous dimension of reality. Others were of the opinion that spontaneous generation is one of the extraordinary marvels exhibited in this world and, accordingly, this interpretation served to accentuate the divine aspect of nature. References to spontaneous generation also appear in legal writings, influencing practical applications such as dietary laws and actions forbidden on the Sabbath.

    The distribution of wealth in the medieval Hungarian aristocratic society is studied and reported. Assuming the wealth of a noble family to be directly related to the size and agricultural potential of the owned land, we take the number of owned serf families as a measure of the respective wealth. Our data analysis reveals the power-law nature of this wealth distribution, confirming the validity of the Pareto law for this society. Since, in the feudal society, land was not commonly traded, our targeted system can be considered as an experimental realization of the no-trade limit of wealth-distribution models. The obtained Pareto exponent ( α=0.92-0.95) close to 1, is in agreement with the prediction of such models.

    A thermodynamic model of glass durability based on hydration of structural units has been applied to natural glass, medieval window glasses, and glasses containing nuclear waste. The relative durability predicted from the calculated thermodynamics correlates directly with the experimentally observed release of structural silicon in the leaching solution in short-term laboratory tests. By choosing natural glasses and ancient glasses whose long-term performance is known, and which bracket the durability of waste glasses, the long-term stability of nuclear waste glasses can be interpolated among these materials. The current Savannah River defense waste glass formulation is as durable as natural basalt from the Hanford Reservation (10/sup 6/ years old). The thermodynamic hydration energy is shown to be related to the bond energetics of the glass. 69 references, 2 figures, 1 table.

    Cranial trepanation is a practice known since prehistory in various, often geographically distant populations. In this work are presented two early medieval trepaned skulls. The first skull comes from Canosa in Apulia (6th-7th c. AD; according to radiocarbon dating), the second is from Ticineto Alessandrino (5th-8th c. AD). The skull of Canosa shows a single perforation on the bregmatic quadrant of the right parietal, whereas the Ticineto skull presents three lesions of different shapes and sizes. Two perforations are on the left parietal and the other is on the right parietal. The lesions of the Ticineto skull can be referred to a therapeutic operation following a trauma, with survival of the individual. In the Canosa skull the absence of a healing reaction suggests a pathological process, without survival of the subject. Moreover, a particular ritual practice cannot be excluded (i.e. a post-mortem trepanation).

    Historians of medieval and early modern psychiatry have utilized limited source materials in their research. They have focused on printed works, particularly formal treatises by celebrated authors, and neglected manuscript collections. The resulting histories depict early European psychiatric thought as dominated by demonology. Examination of the archives of an early English legal incompetency jurisdiction flatly contradicts this picture. Starting in the 13th century, the English government conducted mental status examinations of psychiatrically disabled individuals, using commonsense, naturalistic criteria of impairment; private, supervised guardians were appointed for such persons. Furthermore, etiological theories entertained by royal officials and laymen relied on physiological and psychological notions of psychiatric illness. These findings raise serious questions about conventional accounts of this period and underline the need for more research using original manuscripts. PMID:371576

    Leprosy used to be a widespread, dreaded disease in Europe during the middle ages, and it still remains an important health problem in some parts of the world today. Herein, we present data on the earliest 'Austrian' (an adult female from the early medieval period) proven to have suffered from leprosy. Manifestations of the disease were first identified during a systematic screening of pathological changes in skeletons recovered from an archaeological site in Pottenbrunn (Lower Austria). In the present study, DNA extracts from selected cranial and postcranial bone samples were investigated using polymerase chain reaction primers specific to the Mycobacterium leprae (M. leprae) repetitive element (RLEP). M. leprae traces were detected in extracts from nasal and palatine bones. Sequence analysis of informative polymorphic sites supports previous reports indicating that European M. leprae strains fall into single nucleotide polymorphism group 3. In summary, these findings put Austria on the map of confirmed leprosy cases in ancient Europe.

    Patterns of water consumption by past human populations are rarely considered, yet drinking behavior is socially mediated and access to water sources is often socially controlled. Oxygen isotope analysis of archeological human remains is commonly used to identify migrants in the archeological record, but it can also be used to consider water itself, as this technique documents water consumption rather than migration directly. Here, we report an oxygen isotope study of humans and animals from coastal regions of Croatia in the Iron Age, Roman, and Early Medieval periods. The results show that while faunal values have little diachronic variation, the human data vary through time, and there are wide ranges of values within each period. Our interpretation is that this is not solely a result of mobility, but that human behavior can and did lead to human oxygen isotope ratios that are different from that expected from consumption of local precipitation.

    Iron-arsenic alloys are described in many medieval chemical recipes as a means to "liquefy" iron. In fact, while such alloys have relatively low melting points, they are not the only examples of iron being known as a liquid metal. There is evidence from the analysis of swords, as well as from written references, that crucible steel, probably imported from the Middle East, was known in Western Europe from the Early Middle Ages. In addition, the "blast furnace", which produced liquid pig iron, is now known from archaeological evidence to have been operated from at least the thirteenth century in Scandinavia. The descriptions of iron-smelting and iron-working given in the accounts written by scholastic alchemists are in fact closely related to the contemporary practices of craftsmen operating iron furnaces.

    Throughout history, illustrations had played a key role in the promotion and evolution of medicine by providing a medium for transmission of scientific observations. Due to religious prohibitions, color drawings of the human body did not appear in medieval Persia and during the Islamic Golden Age. This tradition, however, has been overlooked with the publication of the first color atlas and text of human anatomy, Tashrihi Mansuri (Mansur's Anatomy), by Mansur ibn Ilyas in the fourteenth century AD. Written in Persian and containing several vivid illustrations of the human body, this book gained widespread attention by both scholars and lay persons. In this article, a brief history of Mansur's Anatomy and an English translation of selected sections from this book regarding the heart and blood vessels are presented.

    In Middle Ages Astronomy and Music were included in the four sciences, together with Mathematics and Geometry. From ancient times philosophers thought that harmony lies in the basis of world creation. The Earth was in the centre of the Universe, and the seven planets went around it, the Sun and the Moon in their number. Harmony was also in the basis of music, with seven sounds due to seven planets. It was considered that owing to harmonic rotation cosmic universal music appears, and it is not attainable for human ear as it is used to it. Medieval connoisseurs of music therapy believed that for healing a person his astrological data must first be cleared out, in order to define in which musical mode should sound the melody in order to treat him/her. Comparing music with astrology they considered easier to practise the first one because the celestial luminaries are much higher and farther from people.

    Most work on Islamic medical ethics has been in relation to the physician, yet physicians are only one category of many health-related professionals. In view of its role as mediator between the layman and medication, pharmacy is of perhaps equal importance. In medieval Islam, there seems to have been a clear differentiation between the physician and the pharmacist. However, most of our sources reflect the physician's point of view. A text which uniquely reflects that of the pharmacist is the thirteenth-century Minhaj al-dukkan by al-Kuhin al-'Attar of Cairo. A comparison between the ethical contents of this book, and of similar works aimed at physicians, can indicate what the differences and similarities were between the "good physician" and the "good pharmacist." Interestingly, the language used to define the "go od" professional is religiously neutral--there is nothing to evince a particular identity, beyond a general monotheism, on the part of the writers.

    Archaeological excavations carried out in the Medieval village of Geridu (Sardinia) uncovered several burials dating to the late 13th or the first half of 14th century. Among these individuals, the skeleton of an adult female showing a bilateral abnormal shortness of the fourth metatarsal bone was identified. Bilaterality and absence of other skeletal anomalies allow to rule out an acquired aetiology of the disease and to support a diagnosis of congenital brachymetatarsia. Such a rare deformity has a clinical incidence of 0.02% to 0.05%, with strong predominance of the female gender. To our knowledge, no other cases of brachymetatarsia have been reported in paleopathology so far. PMID:24478252

    A multiple dating study, involving a collaboration between specialists of dating techniques (thermoluminescence (TL) and radiocarbon), historians of art and archaeologists, has been carried out on several early medieval buildings from western France. The early medieval period is not well known especially in France where there is a lack of visible evidence that identifies pre-Romanesque architecture. The majority of buildings to have survived from this period are religious ones, considered important enough to be made of strong, non-perishable material such as stone or brick, as for example the churches of Notre-Dame-sous- Terre in the Mont-Saint-Michel or St Martin in Angers. Due to their significance in architectural history, it is imperative to position them accurately in the chronology of the history of art. Bricks are often used to build up round-headed arches or to reinforce the frame of a wall with bonding courses in those churches. TL dating and archeomagnetic analysis were performed on cores drilled within bricks while radiocarbon dating were undertaken on coals found within mortars. In order to increase the number of data during the early Middle Ages, archeointensity determinations using the classical Thellier technique with anisotropy of thermal remanence and cooling rate corrections were performed. Archaeomagnetic directions were used to recognize the firing position of bricsk during manufacture. Reliable and precise ages were obtained on the church Notre-Dame-sous-Terre; they indicate two phases of building in 950±50AD and 990±50AD. Mean archeointensities obtained on 17 (21) samples from the first (second) phases appears very closed 69.1±1.2 and 68.3±1.6 microTesla. Ages and archeomagnetic results obtained on 4 other sites will be presented and compared to the available data in western Europe.

This paper brings together the known details of their lives, compiled from extant biographies and from internal references in their texts. The primary records of their writings exist in handwritten texts and thereafter in incunabula from the time of the invention of printing in 1476. The record of the lives of these two medieval physicians can be expanded, as here, by the general perspective of the life and times in which they lived. Gilbertus Anglicus, an often-quoted physician-teacher at Montpellier, wrote a seven-folio Compendium medicinae in 1271. He described pioneering procedures used later in the emergent disciplines of anaesthetics, cosmetic medicine and travel medicine. Gilbertus' texts, used extensively in European medical schools, passed in handwritten copies from student to student and eventually were printed in 1510. John of Gaddesden, an Oxford graduate in Arts, Medicine and Theology, wrote Rosa Anglica, published circa 1314. Its detailed text is an exemplar of the mixture of received Hippocratic and Galenic lore compounded by medieval astronomy and religious injunction, which mixture was the essence of medieval medicine. The writings of both these medieval English physicians formed part of the core curriculum that underpinned the practice of medicine for the next 400 years.

  7. The origins of intensive marine fishing in medieval Europe: the English evidence.

    The catastrophic impact of fishing pressure on species such as cod and herring is well documented. However, the antiquity of their intensive exploitation has not been established. Systematic catch statistics are only available for ca.100 years, but large-scale fishing industries existed in medieval Europe and the expansion of cod fishing from the fourteenth century (first in Iceland, then in Newfoundland) played an important role in the European colonization of the Northwest Atlantic. History has demonstrated the scale of these late medieval and post-medieval fisheries, but only archaeology can illuminate earlier practices. Zooarchaeological evidence shows that the clearest changes in marine fishing in England between AD 600 and 1600 occurred rapidly around AD 1000 and involved large increases in catches of herring and cod. Surprisingly, this revolution predated the documented post-medieval expansion of England's sea fisheries and coincided with the Medieval Warm Period--when natural herring and cod productivity was probably low in the North Sea. This counterintuitive discovery can be explained by the concurrent rise of urbanism and human impacts on freshwater ecosystems. The search for 'pristine' baselines regarding marine ecosystems will thus need to employ medieval palaeoecological proxies in addition to recent fisheries data and early modern historical records.

    2014-01-01

    Ibn Sina (980–1037 AD), known by his full name Abu Ali al-Hussain ibn Abdallah ibn Sina and the Latin name ‘Avicenna’, was a Persian scholar who is primarily remembered for his contributions to the science of medicine. He authored Al-Qanun fi al-Tibb (The Canon of Medicine). Sections of his work are devoted to detailed descriptions of a number of infectious illnesses, particularly rabies. Avicenna described rabies in humans and animals and explained its clinical manifestations, route of transmission, and treatment methods. In this article, our goal is to discuss Avicenna’s 11th-century points of view on rabies and compare them with modern medical knowledge. PMID:24533686

    Window glass fragments from four Belgian sites were studied and for a set of eighty-five samples the UV-VIS-NIR transmission spectra were analyzed. This collection contains historical and archaeological finds originating from religious buildings namely the Basilica of Our Lady of Hanswijk in Mechelen (17th-20thc) and the Church of Our Lady in Bruges (16th-20thc) as well as from secular buildings as a private house/Antwerp (18th-1948) and the castle of Middelburg-in-Flanders (1448-17thc). All sites contain material on the hinge point between the medieval and the industrial tradition. The variation in composition of the analyzed samples can be explained by the use of different glassmaking recipes, more specifically the use of different raw materials. The composition of window glass differs essentially in the type of flux, using a potash rich fluxing agent until the post-medieval times and industrial soda from the 19th century onwards. A second difference concerns the iron impurities in the glass. For all fragments a clear compositional classification could be made based on the iron concentration. These conclusions were based on archaeological research and drawn after submitting samples to expensive, complex, time-consuming and destructive chemical analyzing methods. Our study indicates that similar conclusions could be made applying the proposed optical based methodology for plain window glass. As a whole, the obtained results make it possible to cluster the fragments for a particular site based on three different sensing parameters: the UV absorption edge, the color and the presence of characteristic absorption bands. This information helps in identifying trends to date window glass collections and indicating the use of different raw materials, production technologies and/or provenance.

    A large number of ceramic samples (from the 10th to the 19th century), found during the excavation of Sicilian archaeological sites (Syracuse, Caltagirone, Sciacca and Piazza Armerina), have been studied by combining scanning electron microscopy, energy-dispersive X-ray spectrometry and optical microscopy. Attention has been focused on the microchemical and microstructural properties of the painted surfaces to investigate the nature of the enamels and pigments in the decorative layers. The general perspective has been the identification of consistent archeometric criteria, other than the standard stylistic considerations, which can be used for a reliable recognition of the production sites. The results collected for each ceramic typology were used to cluster the different ceramic reference groups in a wide database suitable for a reliable discrimination of the provenance of artefacts. Moreover, the same compositional and microstructural data allow the identification of the raw materials used for pigments. There is evidence of some differences with existing information found in the literature concerning the formulas used in ancient times. Finally, attention has also been devoted to identify the technological aspects of the manufacturing techniques and firing conditions adopted for each typology of glaze coating depending on different ceramic materials .

    Link, Fabian

    2014-01-01

    This article investigates the roots of the sub-discipline medieval archaeology that emerged in German-speaking universities in the 1950s and 1960s. In the 1930s, research practices crucial for the formation of medieval archaeology, such as the investigation of medieval castles and peasant houses, became more prominent in the humanities, especially in the context of vilkisch research. After the Nazis took power in Germany, they encouraged such research because it built a scientific basis for their nationalist policy. This politically motivated funding did not result in a new discipline, in contrast to research fields such as prehistory and folklore studies. In this article, I propose two explanations for why medieval archaeology did not emerge as an interdisciplinary research field in the 1930s and 1940s, even though the course was set for its development. First, for archaeologists, art historians, and regional medieval historians, research objects such as medieval castles were semantically too indeterminate. Archaeologists would investigate a castle as a building completely destroyed and buried under rubble, while art historians would be interested in its building technique, and regional medieval historians in its written record. Second, disciplines that were important for the creation of medieval archaeology, such as prehistoric archaeology, art history, and regional medieval history, structurally did not allow for the emergence of an interdisciplinary research field in the 1930s. In particular, prehistoric archaeology, which was crucial for the development of medieval archaeology, itself was not fully institutionalized at universities in the 1930s. This institutionalization process prevented the emergence and development of an interdisciplinary research field such as medieval archaeology To demonstrate this argument, I draw on two examples of investigations of castles, one in Nazi Germany and the other in the German-speaking part of Switzerland.

  15. The chemistry of gaseous acids in medieval churches in Cyprus

    Loupa, G.; Charpantidou, E.; Karageorgos, E.; Rapsomanikis, S.

    Indoor and outdoor concentrations of HCl, HNO 3, HCOOH and CH 3COOH were determined in two medieval churches in Cyprus, during July 2003 and March 2004. The high air exchange rate through the open windows and doors led to lower indoor, compared to outdoor, acid concentrations in July 2003. Indoor pollutant emissions and a low air exchange rate resulted in higher indoor compared to outdoors acid concentrations in both churches during March 2004. Indoor to outdoor inorganic acid ratios were higher than the corresponding indoor to outdoor organic acid ratios during July 2003, whilst the opposite trend was observed during March 2004. Direct acid emission from candle burning appears to play a major role in the observed indoor acid concentrations. Emissions of volatile organic compounds from other sources, like humans, cleaning products and incense, led also to formation or depletion of the gaseous acids via homogeneous photochemical, heterogeneous and dark reaction sequences. Chemical reaction pathways were extensively investigated and appear to explain the observed results. The apparent indoor acid deposition velocities ranged between 0.05 and 0.15 cm s -1.

    Paleopathological data provide valuable information about health, longevity and mortality in earlier human populations. We investigated the incidence of spinal pathologies on 54 individuals (1045 vertebrae and 18 sacral bones) that belong to a medieval skeletal series discovered in the Dalheim monastery (Northwest Germany) and compared them with contemporary and recent populations. The skeletons were analyzed with anthropological methods (sex and age determination), by macroscopic inspection, and, if pathologies of the spine and the sacrum were visible, also by X-ray. We investigated evidence of trauma, specific and nonspecific infectious diseases, joint diseases, tumors, and congenital as well as metabolic disorders. Radiocarbon determination of four samples of different specimens was also undertaken revealing a historic dating of ca. 1050 AD. The most common pathological findings were degenerative changes of the spine found in 29 individuals (53.3%). Examples of infections of the spine were rare (0.8% of all vertebrae). There were no cases of traumatic injuries of the spine. The prevalence of spondylosis deformans, the most commonly found type of pathology was found to be higher in the lumbar region, in males as well as in individuals of low stature.

    Urinary stone was first found by human as early as 4900 BC when the Egyptian monks applied emesis, catharsis, diuresis, and diaphoresis for its treatment which, as they claimed, can expel the stones out of the body occasionally. In 2700 BC, definite records on urinary stone were seen in Egytian papyrus which attempted to cure this disorder by sucking method. In the 4(th) century BC, the Greek physician Alexandria mentioned that such stones can be expelled after being smashed. By then, the Greeks recognized the existence of renal stone by describing its manifestations. Sushruta, an ancient Indian royal physician mentioned in 6(th) century BC, the picking up of stones by splints through the urethra and the complications of such disorder in his Sushrutasamhita. He also recommended the removal of stones through the perineal part. Unfortunately, many patients died of such operation. Ancient Roman physicians described such operation circumstantially and the herbs for its treatment in the 1(st) century BC. During the 10(th) century, the Arabian physician Abukasis was the first to advocate the method of smashing stones in the urethra with an instrument he devised. In the period before medieval age, the removal of urinary stones through the perineal incision had been the main method which was so limited an approach due to the lack of anatomical knowledge and antiseptic conception.

    A multi proxy approach was applied in the reconstruction of the architecture of Medieval horse stable architecture, the maintenance practices associated with that structure as well as horse alimentation at the beginning of 13th century in Central Europe. Finally, an interpretation of the local vegetation structure along Morava River, Czech Republic is presented. The investigated stable experienced two construction phases. The infill was well preserved and its composition reflects maintenance practices. The uppermost part of the infill was composed of fresh stabling, which accumulated within a few months at the end of summer. Horses from different backgrounds were kept in the stable and this is reflected in the results of isotope analyses. Horses were fed meadow grasses as well as woody vegetation, millet, oat, and less commonly hemp, wheat and rye. Three possible explanations of stable usage are suggested. The stable was probably used on a temporary basis for horses of workers employed at the castle, courier horses and horses used in battle. PMID:24670874

    Care in the community for insane people today is more a matter of expert provision than communal support. In consequence, although they are no longer confined to hospital, mentally ill people largely remain marginalised in a society that does not have the resources, nor often the inclination, to take responsibility for their care. The experience of insane people in medieval England seems to have been of a different order, as shown by a particularly well documented case dating from 1383. From the late 13th century congenital idiots were protected by law. Care of lunatics, by contrast, was primarily the responsibility of the family. However, where the family could not or was unwilling to provide, provision was made by the crown. Through the instrument of the inquisition, the diagnosis and social circumstances of each case were determined by commissioners in consultation with a local jury and all interested parties, including the subject himself or herself. The best interests of the subject remained a prime concern, and the settlement that was ordained was tried and enforced in law. The process was confined to those with real or personal estate, but it encompassed poor as well as rich and proved, through the close identity of the local community with the process, to be a sophisticated and effective mechanism for maintaining and sustaining insane people. Unlike today, care in the community was a communal activity that ensured a truly public provision for those who could not look after themselves. Images p1711-a Fig 1 PMID:8541770

    An explanation of medieval practices of meat supply and regulation, using examples drawn from the so-called "Zähringer towns" founded by the Dukes of Zähringen: Bern, Burgdorf, Thun, Murten, Freiburg and Rheinfelden. For the town councils it was important to be able to provide the population with sufficient quantities of good-quality meat at fair prices. After the 14th century the slaughtering of animals had to be carried out in public slaughterhouses. Meat could only be sold publicly, at designated butchers' stalls. Meat and organs were checked on a daily basis by the town's meat inspectors, who verified the names under which products were sold, their price, and hygienic conditions, including the absence of tapeworm larvae. In addition to the publicly-regulated meat trade, town dwellers could also buy meat products at the markets, and could raise their own pigs, sheep and goats to be slaughtered in the back alleys. Permission to raise small livestock at home was a privilege granted by the town council. The sale of meat by non-resident peddlers was officially forbidden, but could not be prevented entirely.

    This paper reviews the state of knowledge in the field of optics, mainly in catoptrics and dioptrics, before the birth of modern science and the well-documented contributions of men such as Kepler and Newton. The paper is not intended to be a comprehensive survey of the subject such as one might find in history of science journals; instead, it is aimed at the curious physicist who has probably been taught that nothing much of note was understood about the behaviour of light, beyond outdated philosophical musings, prior to the seventeenth century. The paper will focus on advances during the medieval period between the ninth and fourteenth centuries, in both the east and the west, when the theories of the Ancient Greeks were tested, advanced, corrected and mathematised. In particular, it concentrates on a multivolume treatise on optics written one thousand years ago by the Arab scholar, Ibn al-Haytham, and examines how it influenced our understanding of the nature of reflection and refraction of light. Even the well-informed physicist should find a few surprises here, which will alter his or her view of the debt we owe to these forgotten scholars.

  2. Galeata: chronic migraine independently considered in a medieval headache classification

    2014-01-01

    Background Chronic migraine is a quite recent concept. However, there are descriptions suggestive of episodic migraine since the beginning of scientific medicine. We aim to review main headache classifications during Classical antiquity and compared them with that proposed in the 11th century by Constantine the African in his Liber Pantegni, one of the most influential texts in medieval medicine. Method We have carried out a descriptive review of Henricum Petrum's Latin edition, year 1539. Results Headache classifications proposed by Aretaeus of Cappadocia, Galen of Pergamun and Alexander of Tralles, all of them classifying headaches into three main types, considered an entity (called Heterocrania or Hemicrania), comparable to contemporary episodic migraine. In ninth book of Liber Pantegni, headaches were also classified into three types and one of them, Galeata, consisted on a chronic pain of mild intensity with occasional superimposed exacerbations. Conclusion In Liber Pantegni we have firstly identified, as a separate entity, a headache comparable to that we currently define as chronic migraine: Galeata. PMID:24655582

    There is a unique cluster of four medieval round churches, linked by a simple geometry, on Bornholm Island in the Baltic Sea. Why so many and why so close together? Immediate simple answers are "Just by chance" and "For no reason." Why are the churches round? "Defense." This essay proposes another hypothesis for this unique situation: the churches are astronomical observatories, meant to solve a scientific problem (Is the Earth really spherical?) and a practical problem (How far is it to sail west to the Orient?). The capacity and desire to find answers, together with other practical needs related to astronomy, can better explain these round churches' special architecture. The geometry that connects them fits the ideal pattern with an angular accuracy of 1 minute of a degree. The round churches may be the earliest astronomical observatories in Christian Europe; other hypotheses have been shown to be untenable. Their location provides for a good method to estimate the Earth's extent in the east-west direction, seemingly the earliest such measurements.

    This essay approaches the medieval Hebrew literature on women's healthcare, with the aim of analysing notions and ideas regarding fertility, pregnancy and childbirth, as conveyed in the texts that form the corpus. Firstly, the work discusses the approach of written texts to pregnancy and childbirth as key elements in the explanation of women's health and the functioning of the female body. In this regard it also explores the role of this approach in the creation of meanings for both the female body and sexual difference. Secondly, it examines female management of pregnancy and childbirth as recorded in Hebrew medical literature. It pays attention to both the attitudes expressed by the authors, translators and copyists regarding female practice, as well as to instances and remedies derived from "local" traditions--that is, from women's experience--in the management of pregnancy and childbirth, also recorded in the texts. Finally, the paper explores how medical theories alien to, or in opposition to, Judaism were adopted or not and, at times, adapted to Jewish notions with the aim of eliminating tensions from the text, on the one hand, and providing Jewish practitioners with adequate training to retain their Christian clientele, on the other.

  9. "By expresse experiment": the doubting midwife Salome in late medieval England.

    2015-01-01

    This article examines late medieval English representations of the startling and apocryphal story of Salome, the skeptical midwife who dares to touch, or at least attempt to touch, the Virgin Mary "in sexu secreto" during a postpartum examination at the nativity. Salome's story originated in the second century, but its late medieval iterations are inflected by a culture interested in evaluating and examining sensory evidence, in both medicine and religion. The story appears in sermon collections, devotional texts, the cycle nativity plays, and John Lydgate's Life of Our Lady, and these variations demonstrate the intersection of gender and experience-based knowledge in medical and devotional contexts. Salome's story provides a unique opportunity to study late medieval interpretations of female medicine, materialism, and spirituality.

  10. The Gendered Nose and its Lack: "Medieval" Nose-Cutting and its Modern Manifestations.

    PubMed

    Skinner, Patricia

    2014-01-01

    Time magazine's cover photograph in August 2010 of a noseless Afghan woman beside the emotive strap line, "What happens if we leave Afghanistan," fuelled debate about the "medieval" practices of the Taliban, whose local commander had instructed her husband to take her nose and ears. Press reports attributed the violence to the Pashtun tradition that a dishonored husband "lost his nose." This equation of nose-cutting with tradition begs questions not only about the Orientalist lens of the western press when viewing Afghanistan, but also about the assumption that the word "medieval" can function as a label for such practices. A study of medieval nose-cutting suggests that its identification as an "eastern" practice should be challenged. Rather clearer is its connection with patriarchal values of authority and honor: the victims of such punishment have not always been women, but this is nevertheless a gendered punishment of the powerless by the powerful.

Using data collated from the records of Winchester College this study follows the lives of 2,692 individuals, and analyses adolescent mortality in the sample group for the period 1393-1540. This study of mortality among 10-18 year olds is the first of its kind to produce data for a sample of adolescents in late medieval England, and thereby contributes significant new data to our understanding of late medieval mortality. These data are placed within the context of that obtained for other medieval population samples, most notably with studies of medieval monastic groups.

  12. Solar Influence on Medieval Megadroughts in the Greater Near East

    2014-12-01

    Recent surveys of medieval era chronicles provide calendar accurate information of years of unusual, extreme weather and climate events in areas surrounding the eastern Mediterranean, between the mid-A.D. 10th century and end of the 11th century. Put together, these documents show that the region was simultaneously afflicted by unprecedented sever and persistent droughts in Egypt's Nile Valley and by unusually cold and dry winters associated with crop failure and loss of pasture areas in present-day Iraq and Iran, and in historical Khurasan. We show that this documentary information is consistent with the annually dated Nile summer flood record as measured at the Cairo Nilometer site and within acceptable dating accuracies with much more coarsely resolved regional paleoclimate proxies. We furthermore note that the timing of these events coincided with the Oort Grand Solar Minimum that reached its peak between A.D. 1040 and 1080. Given the scientific evidence for the impact of solar minima on sea surface temperatures in the equatorial Pacific and how the latter affect the intensity of the African summer monsoon, we argue that the Oort Solar Minimum forced the frequent failure of the Nile summer floods resulting in dearth and famine in Egypt. Furthermore, the simultaneous cold and dry winters in the northern Near East are also consistent with the hypothesized solar minimum influence on the North Atlantic Oscillation and on the intensity of the Siberian High. This interpretation underscores the sensitivity of the climate system to variations in solar irradiance, particularly on multi-decadal time scales, to their role in regional processes, and their impact on human history and may help understand other rapid Mediterranean cooling events that occured during the Holocene.

    The Himalayas and their foreland belong to the world's most earthquake-prone regions. With millions of people at risk from severe ground shaking and associated damages, reliable data on the spatial and temporal occurrence of past major earthquakes is urgently needed to inform seismic risk analysis. Beyond the instrumental record such information has been largely based on historical accounts and trench studies. Written records provide evidence for damages and fatalities, yet are difficult to interpret when derived from the far-field. Trench studies, in turn, offer information on rupture histories, lengths and displacements along faults but involve high chronological uncertainties and fail to record earthquakes that do not rupture the surface. Thus, additional and independent information is required for developing reliable earthquake histories. Here, we present exceptionally well-dated evidence of catastrophic valley infill in the Pokhara Valley, Nepal. Bayesian calibration of radiocarbon dates from peat beds, plant macrofossils, and humic silts in fine-grained tributary sediments yields a robust age distribution that matches the timing of nearby M>8 earthquakes in ~1100, 1255, and 1344 AD. The upstream dip of tributary valley fills and X-ray fluorescence spectrometry of their provenance rule out local sediment sources. Instead, geomorphic and sedimentary evidence is consistent with catastrophic fluvial aggradation and debris flows that had plugged several tributaries with tens of meters of calcareous sediment from the Annapurna Massif >60 km away. The landscape-changing consequences of past large Himalayan earthquakes have so far been elusive. Catastrophic aggradation in the wake of two historically documented medieval earthquakes and one inferred from trench studies underscores that Himalayan valley fills should be considered as potential archives of past earthquakes. Such valley fills are pervasive in the Lesser Himalaya though high erosion rates reduce

    Phototrophic microorganisms are important primary producers on hard rock substrata as well as on building facades. These eukaryotic microalgae and cyanobacteria, along with lichens, have also been recognized as important factors for rock weathering and stone decay. The rock substratum itself mostly provides extreme environmental conditions. Composition and diversity of sub-aeric phototrophic microbial communities is up to now poorly understood. Here we present a comparative study addressing the composition of algal biofilms on sandstone substrata based on the analysis of rDNA clone libraries from environmental samples and enrichment cultures. From a W-exposed, shaded wall area of a medieval castle ruin (Burg Gleichen, Thuringia, Germany cf. Hallmann et al., 2011), green algae like Prasiococcus, Prasiola and Elliptochloris could be retrieved. A ESE, sun-exposed wall section was colonized mainly by Apatococcus, Phyllosiphon and the lichen alga Trebouxia and Myrmecia. Accordingly, cyanobacterial communities show clear differences between both wall areas: the sun exposed area was dominated by Synechococcus-like organisms while on the W-exposed area cyanobacteria were almost absent. Just a few species, in particular Stichococcus-related strains, are ubiquitous in both areas. It is obvious that, apart from few generalists, different species colonize the wall areas that are situated in close vicinity, but provide different microclimatic conditions. These differences are discussed in view of biogenic weathering phenomena: certain microalgal species colonize crusts and scales along fracture planes and may contribute to rapid detachment and turnover of dimension stone surfaces.

    Compositional characterization of limestone from sources known to medieval craftsmen and from the monuments they built can be used in conjunction with stylistic and iconographic criteria to infer geographic origin of sculptures that have lost their histories. Limestone from 47 quarrying locations in France and from numerous medieval monuments have been subjected to neutron activation analysis (NAA) to form the nucleus of the Brookhaven Limestone Database. Even though the method and techniques of NAA are well established, this paper briefly summarizes the parameters and experimental conditions useful for determining those concentration variables for which limestone from different sources exhibits significant and reproducible differences.

    1996-01-01

    Relying on their patients' complaints, medieval physicians did not discriminate theoretically between sickness and health. As for the types of illness, there were two different concepts of disease: The semiotic tracts (sphygmology, uroscopy, hematoscopy) describe signs of dyscrasia and locus affectus, while the medical handbooks combine symptoms like fever, pain, nausea, constipation etc. with the signs of pulse, urine and blood. The term "diagnosis" should be used only for this latter type of disease. Because of the ancient model of humoral pathology and because of the deductive construction of symptomatology, "medieval" illnesses cannot be compared with "ours".

  17. Padua and the Stars: Medieval Painting and Illuminated Manuscripts

    Canova, G. M.

    2011-06-01

    In the Middle Ages, the University of Padua was one of the most prominent centre for astrological studies in Europe. The Paduan doctor and philosopher, Pietro d'Abano, who lived in the first decades of the 14th century, was the main figure in this field. At the end of the 13th century, during a long stay in Paris, he got in contact with the new astrological doctrines flourished after the translation into Latin of Ptolemy's and Arab's works in Spain. Thus, when he went back to Padua, he published several studies on the influence of celestial bodies on human life and human physical characteristics and psychology. These ideas deeply affected the Paduan society of the 14th century and, consequently, the most important painters chose or were asked to evoke the images of stars, planets, and their properties. This adventure began with Giotto who shows a surprising interest in celestial bodies in the Scrovegni Chapel where he represented a comet, and soon after he produced a cycle of astrological paintings on the vault of the Palazzo della Ragione in the Public Palace of Padua. Unfortunately, in 1420, these paintings were destroyed in a fire, but the magnificent cycle of astrological frescoes realized soon after on the walls of the same room gives us some clues on Giotto's work and shows us the complexity of the Medieval astrological science. Other astrological paintings, still preserved, were realized by the painters of the Carrarese Court such as Guariento, who painted the planets and their influences on human ages in the church of the Eremitani, and Giusto dei Menabuoi who represented a superb zodiac around a realistic map of Earth in the Cathedral Baptistery. So Padua really became the capital of astrological painting in Europe. Other evidence of the astrological image in the Veneto Region, between the 14th and 15th centuries, can be found in the manuscripts illuminated in the milieu of the University of Padua and in the first books printed in Venice.

    2013-12-01

    The population history of the East Slavs is complicated. There are still many unanswered questions relating to the origins and formation of the East Slavic gene pool. The aims of the current study were as follows: (1) to assess the degree of biological affinity in medieval East Slavic tribes and to test the hypothesis that East Slavic peoples have a common origin; (2) to show their genetic connections to the autochthonous populations of the northern part of Eastern Europe (Baltic and Finno-Ugric tribes); and (3) to identify a genetic continuity between the bearers of Chernyakhov culture and medieval Eastern Slavs. In this study, nonmetric cranial trait data for medieval East Slavic tribes and comparative samples from unrelated groups were examined. Analyzes of phenotypic differentiation were based on Nei's standard genetic distance and hierarchical GST statistics. The results obtained suggest that the genetic affinity of the East Slavic tribes is due not only to inter-tribal gene flow, but is, more importantly, a result of their common population history. Evidence of gene flow from the Baltic and Finno-Ugric groups was showed in the gene pool of Eastern Slavs, as was genetic continuity between medieval East Slavic tribes and the populations of the preceding Chernyakhov culture. These findings support a "generalizing" hypothesis of East Slavic origin, in which a Slavic community was formed in some particular ancestral area, and subsequently spread throughout Eastern Europe.

    2014-01-01

    Within late medieval learned medicine, natural death functioned both as a theoretical concept and as a goal for practice. Late medieval commentaries on Avicenna's Canon are used as source material in this study, in order to investigate the ways in which these learned medical authors envisaged natural death. The findings are compared to descriptions of natural death by natural philosophers, and to ideals of dying in broader medieval culture. According to the physicians, natural death was caused by the extinction of innate heat, due to a lack of innate moisture. They discussed natural death in relation to regimen, as the right regimen protected the body's heat and moisture, and thus helped a patient to keep natural death aloof. So, in order to think about natural death, the physicians turned to the whole of life, during which heat dried out moisture and regimens ought to be followed. By contrast, natural philosophers tended to focus on the moment of death itself. The comparison of natural death with the Good Death in broad medieval culture highlights the amoral nature of the natural death.

  14. Drought as a Catalyst for Early Medieval European Subsistence Crises and Violence

    2016-04-01

    Tree-ring records provide one of most reliable means of reconstructing past climatic conditions, from longer-term multi-decadal fluctuations in temperature and precipitation to inter-annual variability, including years that experienced extreme weather. When combined with written records of past societal behaviour and the incidence of major societal stresses (e.g., famine, disease, and conflict), such records hold the potential to shed new light on historical interactions between climate and society. Recent years have seen the continued development of long dendroclimatic reconstructions, including, most recently the development of the Old World Drought Atlas (OWDA; Cook et al., 2015) which for the first time makes available a robust reconstruction of spring-summer hydroclimatic conditions and extremes for the greater European region, including the entirety of the Dark Ages. In this paper, we examine the association between hydroclimatic extremes identified in the OWDA and well-dated reports of severe drought in early medieval European annals and chronicles, and find a clear statistical correspondence, further confirming the accuracy of the OWDA and its importance as an independent record of hydroclimatic extremes, a resource that can now be drawn upon in both paleoclimatology and studies of climatic impacts on human society. We proceed to examine the association between hydroclimatic extremes identified in the OWDA and the incidence of a range of major societal stresses (scarcity and famine, epidemic disease, and mass human mortality) drawn from an exhaustive survey of early medieval European annals and chronicles. The outcome of this comparison firmly implicates drought as a significant driver of major societal stresses during early medieval times. Using a record of the violent killings of societal elites recorded on a continuous annual basis in medieval Irish monastic annals, we further examine the role of hydroclimatic extremes as triggers in medieval violence

  15. Mercury and sulphur among the High Medieval alchemists: from Rāzī and Avicenna to Albertus Magnus and pseudo-Roger Bacon.

    PubMed

    Newman, William R

    2014-11-01

    This essay challenges the often expressed view that the principles of metals, namely mercury and sulphur, were generally viewed by alchemists as being of a 'metaphysical' character that made them inaccessible to the tools and operations of the laboratory. By examining a number of Arabo-Latin and Latin alchemical texts in circulation before the end of the thirteenth century, the author presents evidence that most alchemists of the period considered mercury and sulphur to be materials subject to techniques of purification in the same way that naturally occurring salts and minerals could be freed of their impurities or dross. The article also points to the immense influence of Avicenna and Albertus Magnus in formulating the theory that mercury and sulphur were compounds of different materials, containing both fixed and unfixed components. Finally, the author briefly examines the relationship between this materialist approach to the principles and the chymical atomism of early modern authors who were deeply aware of medieval alchemical literature.

    We retrieved 34 medieval ovicaprine remains, from three archaeological sites of central Italy dating to about 1000 years old, and analyzed them using mitochondrial DNA. We compared the reconstructed haplogroups with modern sheep samples from Europe and the Middle East and sequences from the literature. In modern sheep, haplogroup HA is present in countries with access to the Mediterranean and close to the domestication center, whereas it is very rare or absent in the rest of Europe. The haplogroup HB was predominant in ancient samples (90%), whereas haplogroup HA was found at 10%. Ancient haplogroups match the present distribution in modern sheep in Italy, indicating that the current proportion of HA/HB was already established in the Middle Ages and is not the result of subsequent events such as selective breeding practices.

  18. The Impact of Devegetated Dune Fields on North American Climate During the Late Medieval Climate Anomaly

    2011-01-01

    During the Medieval Climate Anomaly, North America experienced severe droughts and widespread mobilization of dune fields that persisted for decades. We use an atmosphere general circulation model, forced by a tropical Pacific sea surface temperature reconstruction and changes in the land surface consistent with estimates of dune mobilization (conceptualized as partial devegetation), to investigate whether the devegetation could have exacerbated the medieval droughts. Presence of devegetated dunes in the model significantly increases surface temperatures, but has little impact on precipitation or drought severity, as defined by either the Palmer Drought Severity Index or the ratio of precipitation to potential evapotranspiration. Results are similar to recent studies of the 1930s Dust Bowl drought, suggesting bare soil associated with the dunes, in and of itself, is not sufficient to amplify droughts over North America.

    It is known long since that a number of exceptional and highly impressive astronomical events have been represented in Medieval artworks. We just remember the Bayeux Tapestry and Giotto's The Adoration of the Magi in the Scrovegni Chapel in Padua, representing the P/Halley comet transits of 1067 and 1301, respectively, while The Apparition of Star to Magi fresco in the San Pietro in Valle Abbey in Ferentillo (1182) has been suggested to represent the 1181 supernova. However, no systematic survey of figurative Medieval and Renaissance art has been performed to date, in order to analyzing the role of transient astronomical events as inspiration sources of artworks in these epochs. In this work, we analyze a significant number of artworks, dated between the 9th and 16th century and representing figurative elements in some way connected with astronomy, in order to evaluate if they have been influenced by coeval extraordinary astronomical events.

    The link between hygiene and the concept of transmission of infective diseases was established earlier than the birth of microbiology, thanks to the studies of two neglected physicians of maternity clinic, Ignác Fülöp Semmelweis and Oliver Holmes, in the mid-1800s. Surprisingly, centuries earlier, a medieval women physician, Trotula de Ruggiero, introduced for the first time the notion of diseases’ prevention, highlighting the importance of the association of personal hygiene, balanced nutrition and physical activity for better health. Moreover, she was particularly concerned of hands hygiene for the midwives during child birth, to preserve the good health of both the mother and the baby. She practiced inside the medieval Medical School of Salerno, whose main text, the “Regimen Sanitatis Salerni” has an entire part dedicated to hygiene, providing hygienic precepts that anticipate the concepts derived from the revolutionary discoveries in medical science only centuries later.

    In this paper we present a model based on the principles of Linked Data that can be used to describe the interrelationships of images, texts and other resources to facilitate the interoperability of repositories of medieval manuscripts or other culturally important handwritten documents. The model is designed from a set of requirements derived from the real world use cases of some of the largest digitized medieval content holders, and instantiations of the model are intended as the input to collection-independent page turning and scholarly presentation interfaces. A canvas painting paradigm, such as in PDF and SVG, was selected based on the lack of a one to one correlation between image and page, and to fulfill complex requirements such as when the full text of a page is known, but only fragments of the physical object remain. The model is implemented using technologies such as OAI-ORE Aggregations and OAC Annotations, as the fundamental building blocks of emerging Linked Digital Libraries. The model and implementation are evaluated through prototypes of both content providing and consuming applications. Although the system was designed from requirements drawn from the medieval manuscript domain, it is applicable to any layout-oriented presentation of images of text.

Fragmentary details of his life and medical influence are known from seven books, particularly his extensive (163 chapters) text Lilium Medicine and from Chaucer's reference to him in the Canterbury Tales. Chaucer lists Bernard de Gordon as one whose writings were part of the core curriculum of the best-trained European doctors of medieval Europe. Bernard de Gordon was one of that small group of medieval physicians who reverently followed Galenic lore which had endured for a thousand years yet who began to challenge its details and to experiment clinically with new methods of treatment. In his writings, Bernard de Gordon made the first reference to spectacles and to the hernial truss. His writings also contained detailed desiderata for the ethical best practice of medicine of his day, extending the principles of both Hippocrates and Haly ibn Abbas. Unlike many of the surviving writings of other medieval medical teachers, his texts have within them a tone of humility and acknowledged fallibility. Bernard de Gordon holds a small but significant place in the evolving pre-Renaissance chronology of medical professionalism.

    A new 2400-year paleoclimate reconstruction from Chesapeake Bay (CB) (eastern US) was compared to other paleoclimate records in the North Atlantic region to evaluate climate variability during the Medieval Climate Anomaly (MCA) and Little Ice Age (LIA). Using Mg/Ca ratios from ostracodes and oxygen isotopes from benthic foraminifera as proxies for temperature and precipitation-driven estuarine hydrography, results show that warmest temperatures in CB reached 16-17. ??C between 600 and 950. CE (Common Era), centuries before the classic European Medieval Warm Period (950-1100. CE) and peak warming in the Nordic Seas (1000-1400. CE). A series of centennial warm/cool cycles began about 1000. CE with temperature minima of ~. 8 to 9. ??C about 1150, 1350, and 1650-1800. CE, and intervening warm periods (14-15. ??C) centered at 1200, 1400, 1500 and 1600. CE. Precipitation variability in the eastern US included multiple dry intervals from 600 to 1200. CE, which contrasts with wet medieval conditions in the Caribbean. The eastern US experienced a wet LIA between 1650 and 1800. CE when the Caribbean was relatively dry. Comparison of the CB record with other records shows that the MCA and LIA were characterized by regionally asynchronous warming and complex spatial patterns of precipitation, possibly related to ocean-atmosphere processes. ?? 2010.

    Droughts in the western U.S. in the past 200 years are small compared to several megadroughts that occurred during Medieval times. We reconstruct duration and magnitude of extreme droughts in the northern Sierra Nevada from hydroclimatic conditions in Fallen Leaf Lake, California. Stands of submerged trees rooted in situ below the lake surface were imaged with sidescan sonar and radiocarbon analysis yields an age estimate of ˜1250 AD. Tree-ring records and submerged paleoshoreline geomorphology suggest a Medieval low-stand of Fallen Leaf Lake lasted more than 220 years. Over eighty more trees were found lying on the lake floor at various elevations above the paleoshoreline. Water-balance calculations suggest annual precipitation was less than 60% normal from late 10th century to early 13th century AD. Hence, the lake's shoreline dropped 40-60 m below its modern elevation. Stands of pre-Medieval trees in this lake and in Lake Tahoe suggest the region experienced severe drought at least every 650-1150 years during the mid- and late-Holocene. These observations quantify paleo-precipitation and recurrence of prolonged drought in the northern Sierra Nevada.

We reconstruct duration and magnitude of extreme droughts in the northern Sierra Nevada from hydroclimatic conditions in Fallen Leaf Lake, California.

    Typical engineering methods utilized to calculate stresses on a roof structure involve simplifying assumptions that render a complex non-linear structure a simple and basic determinate beam. That is, instead of considering the composite action of the entire roof structure, the engineer evaluates only a single beam that is deemed conservatively to represent an affected rafter or top chord of a truss. This simplification based on assumptions of a complex problem is where significant conservatism can be introduced. Empirical data will be developed to evaluate this issue. Simple wood beams will be tested to failure. More complex and complete sections of roof structures that include composite action will also be tested to failure. The results can then be compared. An initial step in this process involves a literature review of any work that has been performed on roof structure composite action. The following section summarizes the literature review that was completed.

    The present study showed that ancient parasite eggs, not commonly present in soil samples from medieval Korean tombs, have been found in a very limited number of cases that satisfy certain archaeological requirements. In our paleo-parasitological examination of soil samples from medieval tombs encapsulated by a lime soil mixture barrier (LSMB), parasite eggs were more commonly detected in tombs that contained remains with clothes, hair, or brain tissue, though samples from not all such tombs contained eggs. Nonetheless, there was a close correlation between the preservation of certain types of cultural or human remains and the presence of ancient parasite eggs within medieval Korean LSMB tombs. Such remains, therefore, could be regarded as a strong predictor of well-preserved ancient parasite eggs in soil samples from LSMB tombs. PMID:19954260

    The articular-eminence inclination is an important element in the biomechanics of the temporomandibular joint and the entire masticatory system; however, very little is known about this inclination in archaeological human populations. Therefore, the aim of this study was to determine the values of, in addition to the differences between, the articular-eminence inclination in medieval and contemporary human populations. The study was carried out on two dry skull groups. The first group consisted of 14 dry skulls from the medieval culture group Bijelo Brdo (BB) of East Croatia, and the other consisted of 137 recent dry skulls from the osteologic collection of the Institute of Anatomy (IA) in Zagreb. All BB skulls were dentulous, whereas the IA skulls were divided into dentulous and edentulous groups. The articular-eminence inclination was measured in relation to the Frankfurt horizontal plane on digital images of the skull's two lateral views using AutoCAD computer software. The mean value of the articular-eminence inclination in the BB sample group (49.57°) was lower, with a statistical significance (p<0.01), than those of the IA dentulous (61.56°), the IA edentulous (62.54°), and all the combined IA (61.99°) specimens. Because the values of the articular-eminence inclination can vary a lot with reference to the number of specimens and the different methods used for measuring, the obtained values yield only orientational information. Further investigations including a larger number of medieval specimens are needed to confirm the results obtained from this study. PMID:22721644

    The Central European Watershed divides the Rhine-Main catchment and the Danube catchment. In the Early Medieval period, when ships were important means of transportation, Charlemagne decided to link both catchments by the construction of a canal connecting the Schwabian Rezat and the Altmühl rivers. The artificial waterway would provide a continuous inland navigation route from the North Sea to the Black Sea. The shortcut is known as Fossa Carolina and represents one of the most important Early Medieval engineering achievements in Europe. Despite the important geostrategic relevance of the construction it is not clarified whether the canal was actually used as a navigation waterway. We present new geophysical data and in situ findings from the trench fills that prove for the first time a total length of the constructed Carolingian canal of at least 2300 metres. We have evidence for a conceptual width of the artificial water course between 5 and 6 metres and a water depth of at least 60 to 80 cm. This allows a crossing way passage of Carolingian cargo scows with a payload of several tons. There is strong evidence for clayey to silty layers in the trench fills which reveal suspension load limited stillwater deposition and, therefore, the evidence of former Carolingian and post-Carolingian ponds. These findings are strongly supported by numerous sapropel layers within the trench fills. Our results presented in this study indicate an extraordinarily advanced construction level of the known course of the canal. Here, the excavated levels of Carolingian trench bottoms were generally sufficient for the efficient construction of stepped ponds and prove a final concept for a summit canal. We have evidence for the artificial Carolingian dislocation of the watershed and assume a sophisticated Early Medieval hydrological engineering concept for supplying the summit of the canal with adequate water.

    Sea surface temperature (SST), salinity, and flux of terrigenous material oscillated on millennial time scales in the Pleistocene North Atlantic, but there are few records of Holocene variability. Because of high rates of sediment accumulation, Holocene oscillations are well documented in the northern Sargasso Sea. Results from a radiocarbon-dated box core show that SST was approximately 1°C cooler than today approximately 400 years ago (the Little Ice Age) and 1700 years ago, and approximately 1°C warmer than today 1000 years ago (the Medieval Warm Period). Thus, at least some of the warming since the Little Ice Age appears to be part of a natural oscillation.

    An examination of the, apparently meteoritic, object, anciently called the Palladium after the Greek goddess Pallas Athene, is presented, as discussed in various ancient and early medieval sources. Although made of wood, the Palladium was believed to have fallen from the sky. In myths, it was a powerful totemic object, first at the legendary city of Troy, then later at Rome, and had magically protective properties associated with it. Despite its implausibly meteoritic nature, the Palladium can be suggested as supporting the case for ancient meteorite worship.

Spandrels of post-medieval buildings (late XVI to early XX century) have been analysed, with emphasis on morphological characteristics according to chronological indicators. Results of the experimentation on scaled models (1:10) are discussed and the better behaviour of historical masonry typologies on respect to the modern one is highlighted. Comparison with theoretical formulations of ultimate shear resistance are provided too.

The research has led to the first identification of lapis lazuli in a blue pigment pottery glaze; the identification was confirmed for six other shards from the same site. The brown—black pigment in these shards could not be identified.

    Determination of copper concentrations in Greenland ice dated from seven millennia ago to the present showed values exceeding natural levels, beginning about 2500 years ago. This early large-scale pollution of the atmosphere of the Northern Hemisphere is attributed to emissions from the crude, highly polluting smelting technologies used for copper production during Roman and medieval times, especially in Europe and China. This study opens the way to a quantitative assessment of the history of early metal production, which was instrumental in the development of human cultures during ancient eras. 27 refs., 1 fig., 2 tabs.

    Digital methods, tools and algorithms are gaining in importance for the analysis of digitized manuscript collections in the arts and humanities. One example is the BMBF-funded research project "eCodicology" which aims to design, evaluate and optimize algorithms for the automatic identification of macro- and micro-structural layout features of medieval manuscripts. The main goal of this research project is to provide better insights into high-dimensional datasets of medieval manuscripts for humanities scholars. The heterogeneous nature and size of the humanities data and the need to create a database of automatically extracted reproducible features for better statistical and visual analysis are the main challenges in designing a workflow for the arts and humanities. This paper presents a concept of a workflow for the automatic tagging of medieval manuscripts. As a starting point, the workflow uses medieval manuscripts digitized within the scope of the project Virtual Scriptorium St. Matthias". Firstly, these digitized manuscripts are ingested into a data repository. Secondly, specific algorithms are adapted or designed for the identification of macro- and micro-structural layout elements like page size, writing space, number of lines etc. And lastly, a statistical analysis and scientific evaluation of the manuscripts groups are performed. The workflow is designed generically to process large amounts of data automatically with any desired algorithm for feature extraction. As a result, a database of objectified and reproducible features is created which helps to analyze and visualize hidden relationships of around 170,000 pages. The workflow shows the potential of automatic image analysis by enabling the processing of a single page in less than a minute. Furthermore, the accuracy tests of the workflow on a small set of manuscripts with respect to features like page size and text areas show that automatic and manual analysis are comparable.

    In this work, microspectrofluorimetry was for the first time applied to the identification of the red organic lakes that are characteristic of the lavish illuminations found in 15(th) century books of hours. Microspectrofluorimetry identified those red paints, ranging from opaque pink to dark red glazes, as brazilwood lakes. An unequivocal characterization was achieved by comparison with reference paints produced following recipes from the medieval treatise The Book on How to Make Colours, and was further confirmed by fiber optic reflectance spectroscopy (FORS). For these treasured cultural objects, microspectrofluorimetry and FORS proved to be the only techniques that could identify, in situ or in microsamples, the chromophore responsible for the pinkish hues: a brazilein-Al(3+) complex. Additionally, a multi-analytical approach provided a full characterization of the color paints, including pigments, additives, and binders. Microspectroscopic techniques, based on infrared and X-ray radiation, enabled us to disclose the full palette of these medieval manuscripts, including the elusive greens, for which, besides malachite, basic copper sulfates were found; Raman microscopy suggested a mixture of brochantite and langite. Infrared analysis proved invaluable for a full characterization of the additives that were applied as fillers or whites (chalk, gypsum, and white lead) as well as the proteinaceous and polysaccharide binders that were found pure or in mixture.

    Metallurgical characterization of a sword blade fragments dating from the second half of the 15th century found in central Slovenia was performed in order to determine its chemical composition, microstructure, microhardness, and to obtain insight into the methods of manufacture of a late-medieval Messer sword. As the artefact was broken, examinations were limited to six very small fragments that were allowed to be removed from the cutting edge, core and the back of the blade. Light optical microscopy, scanning electron microscopy, energy dispersive X-ray spectroscopy, energy dispersive X-ray fluorescence spectrometry, differential scanning calorimetry, thermodynamics approach and Vickers micro-hardness tests were employed to analyze the microstructure and mechanical properties. The results show that the sword was manufactured from a single wrought iron billet. The surface of the sword was carburized. No evidence of quenching was found. The ferritic microstructure is concentrated in the core, and the pearlitic in the outer layer of the blade. All metal fragments contained non-metallic inclusions that were derived mostly from slag and some from hammer scale. - Highlights: • A metallurgical characterization of a medieval sword blade has been performed. • The carbon content decreased from the surface to the core of the blade. • The dominant microstructure in the outer layer is pearlite and in the core is ferrite. • The presence of lump shaped and elongated non-metallic inclusions was observed. • The sword was manufactured from a single wrought iron billet.

  11. Alchemical poetry in medieval and early modern Europe: a preliminary survey and synthesis. Part II - Synthesis.

    2011-03-01

    This article provides a preliminary description of medieval and early modern alchemical poetry composed in Latin and in the principal vernacular languages of western Europe. It aims to distinguish the various genres in which this poetry flourished, and to identify the most representative aspects of each cultural epoch by considering the medieval and early modern periods in turn. Such a distinction (always somewhat artificial) between two broad historical periods may be justified by the appearance of new cultural phenomena that profoundly modified the character of early modern alchemical poetry: the ever-increasing importance of the prisca theologia, the alchemical interpretation of ancient mythology, and the rise of neo-Latin humanist poetry. Although early modern alchemy was marked by the appearance of new doctrines (notably the alchemical spiritus mundi and Paracelsianism), alchemical poetry was only superficially modified by criteria of a scientific nature, which therefore appear to be of lesser importance. This study falls into two parts. Part I provides a descriptive survey of extant poetry, and in Part II the results of the survey are analysed in order to highlight such distinctive features as the function of alchemical poetry, the influence of the book market on its evolution, its doctrinal content, and the question of whether any theory of alchemical poetry ever emerged. Part II is accompanied by an index of the authors and works cited in both parts. PMID:21797075

    Traumatic injuries can be used as general indicators of activity patterns in past populations. This study tests the hypothesis that contemporaneous (10th-12th century) rural and urban populations in medieval Poland will have a significantly different prevalence of non-violent fractures. Traumatic injuries to the post-cranial skeleton were recorded for 180 adults from rural Giecz and for 96 adults from urban Poznań-Śródka. They were statistically analyzed by body region and individual skeletal element. Results reveal that Giecz had a significantly higher rate of trunk fractures than Poznań-Śródka (Fisher's exact, p<0.05). In particular, rib and vertebral fractures were more common in Giecz males and females than in their Poznań-Śródka counterparts. Traumatic injuries in the extremities were comparable between the two samples, suggesting similar risks of trauma to these regions. These results indicate that in early medieval Poland, activities associated with a rural lifestyle resulted in more injuries. These stress or accidental fractures, which are related to a high-risk setting, were not consistent with an urban lifestyle. Overall, agricultural populations like Giecz were engaged in a laborious lifestyle, reflected in a variety of injuries related to repetitive, high-risk activities. Although urban populations like Poznań engaged in craft specialization participated in repetitive activities, their lifestyle resulted in lesser fracture-risk.

    We present a rare case of infratentorial mastoid trepanation, by drilling, from medieval Croatia. An artificial ante-mortal opening was found in a male skeleton from the 11th century cemetery Zvonimirovo. It was placed roughly at the intersection of the Frankfurt's plane and the midline of the right mastoid. The right posterior parietal of the deceased also exhibited a callus-like formation consistent with the linear cranial fracture. Our aim was to investigate by computed tomography (CT) a possible presence of otopathology--a chronic middle ear infection--MEI/mastoiditis or cholesteatoma. On the other hand, both standard radiography and CT were employed in a cranial fracture diagnostic agreement. The generated CT scans confirmed the presence of an artificial hole running into a well defined trepanne canal connected with the antrum. The presence of otopathology was not established. The radiography and CT substantiated the presence of a linear posterior parietal discontinuity--without displacement, in front of the right lambdoid suture. From the medical point of view, it would be unusual to perform infratentorial--mastoid trepanation for reasons of treating supratentorial trauma, i.e. possible posttraumatic acute subdural hematoma (PTASDH). However, since there was a lack of CT evidence of osteolysis in ME, there is a possibility of medieval trepanation procedure performed for reasons of posttraumatic treat- ment. To our best knowledge, usually, ancient trepanations described in Croatian bioarchaeology and all over the world are supratentorial and do not always reveal such sophisticated surgical techniques.

    Traumatic injuries can be used as general indicators of activity patterns in past populations. This study tests the hypothesis that contemporaneous (10th–12th century) rural and urban populations in medieval Poland will have a significantly different prevalence of non-violent fractures. Traumatic injuries to the post-cranial skeleton were recorded for 180 adults from rural Giecz and for 96 adults from urban Poznań-Śródka. They were statistically analyzed by body region and individual skeletal element. Results reveal that Giecz had a significantly higher rate of trunk fractures than Poznań-Śródka (Fisher’s exact, p<0.05). In particular, rib and vertebral fractures were more common in Giecz males and females than in their Poznań-Śródka counterparts. Traumatic injuries in the extremities were comparable between the two samples, suggesting similar risks of trauma to these regions. These results indicate that in early medieval Poland, activities associated with a rural lifestyle resulted in more injuries. These stress or accidental fractures, which are related to a high-risk setting, were not consistent with an urban lifestyle. Overall, agricultural populations like Giecz were engaged in a laborious lifestyle, reflected in a variety of injuries related to repetitive, high-risk activities. Although urban populations like Poznań engaged in craft specialization participated in repetitive activities, their lifestyle resulted in lesser fracture-risk. PMID:26068106

  15. Two medieval plague treatises and their afterlife in early modern England.

    This study of an adaptation of the popular John of Burgundy plague treatise by Thomas Moulton, a Dominican friar, ca. 1475, and a translation of the so-called Canutus plague treatise by Thomas Paynell, printed 1534, shows how the medieval traditions they represent were carried forward, well into the sixteenth century, and also subjected to change in light of religious, moral, and medical concerns of early modern England. The former had a long life in print, ca. 1530-1580, whereas Paynell's translation exists in one printed version. Moulton's adaptation differs from its original and from the Canutus treatise in putting great emphasis on the idea that onsets of plague were acts of divine retribution for human sinfulness. In this respect, Moulton reshaped the tradition of the medieval plague treatise and anticipated the religious and social construction of plague that would take shape in the first half of the sixteenth century. Its long history in print indicates that Moulton's treatise expressed the spirit of that construction and probably influenced the construction as well. The contrasting histories of the two treatises attest not only to the dramatic change brought about by religious and social forces in the sixteenth century, but to a growing recognition of the value of the printing press for disseminating medical information-in forms that served social and ideological ends.

  16. Medieval and Renaissance anatomists: the printing and unauthorized copying of illustrations, and the dissemination of ideas.

    The vanguard that began to question Galenic anatomical dogma originated in northern Italy in the latter half of the thirteenth century, and not coincidentally this was where human dissection was introduced, which in turn eventually fostered the origins of realistic anatomical illustration in the late fifteenth century. With the advent of the printing press and moveable type at this time, printed books began to supersede hand-copied medieval manuscripts, and labor-intensive techniques were soon developed to integrate text and illustrations on the printed page. The same technology was used to pirate the illustrations of prior authors with varying fidelity. Specific medieval and Renaissance anatomical illustrations can often be traced from their inceptions through different stages of development to the final printed images, and then through subsequent pirated versions in various abridgements or other compendia. The most important milestone in the development of anatomy and anatomical illustration was the publication in 1543 by Andreas Vesalii of De humani corporis fabrica (On the Fabric of the Human Body), commonly referred to simply as the Fabrica. With this work, Vesalii succeeded in coordinating a publication production team (author, artists, block cutters, publisher, and typesetters) to achieve an unprecedented integration of scientific discourse, medical illustration, and typography. However, despite Vesalii's valiant efforts to prevent unauthorized duplication, the illustrations from the Fabrica were extensively plagiarized. Although Vesalii found such piracy frustrating and annoying, the long-term effect was to make Vesalii's ideas known to a wider readership and to help solidify his own revolutionary contributions to anatomy.

    In this work, microspectrofluorimetry was for the first time applied to the identification of the red organic lakes that are characteristic of the lavish illuminations found in 15(th) century books of hours. Microspectrofluorimetry identified those red paints, ranging from opaque pink to dark red glazes, as brazilwood lakes. An unequivocal characterization was achieved by comparison with reference paints produced following recipes from the medieval treatise The Book on How to Make Colours, and was further confirmed by fiber optic reflectance spectroscopy (FORS). For these treasured cultural objects, microspectrofluorimetry and FORS proved to be the only techniques that could identify, in situ or in microsamples, the chromophore responsible for the pinkish hues: a brazilein-Al(3+) complex. Additionally, a multi-analytical approach provided a full characterization of the color paints, including pigments, additives, and binders. Microspectroscopic techniques, based on infrared and X-ray radiation, enabled us to disclose the full palette of these medieval manuscripts, including the elusive greens, for which, besides malachite, basic copper sulfates were found; Raman microscopy suggested a mixture of brochantite and langite. Infrared analysis proved invaluable for a full characterization of the additives that were applied as fillers or whites (chalk, gypsum, and white lead) as well as the proteinaceous and polysaccharide binders that were found pure or in mixture.

    In a comparison among numerical models of storms and tsunamis, only tsunami waves of nearby origin manage to wash over an area where coral heads of medieval age are scattered hundreds of meters inland from the north shore of Anegada, British Virgin Islands. This low-lying island faces the Puerto Rico Trench 120 km to the north. The island's north shore, fringed by a coral reef 100-1200 m offshore, displays geological evidence for two levels of overwash. The medieval overwash, dated to AD 1200-1450, was the higher one. It is evidenced by scores of coral boulders scattered hundreds of meters inland. Some of them crossed the area of the modern storm berm at Soldier Wash, continued across a broad limestone rise 3-4 m above sea level, and came to rest on lower ground farther inland. Coral heads in four other areas, also medieval or older, came to rest hundreds of meters inland from beach ridges now 2-4 m above sea level. The later, lower-elevation overwash, dated to AD 1650-1800, laid down a sheet of sand and shell that extends as much as 1.5 km inland. The hypothetical causes for each event, tested by numerical modeling, include (1) category IV and V hurricanes that differ in surge and wave heights; (2) the 1755 Lisbon earthquake or hypothetical medieval predecessor, at M 8.7 and M 9.0; (3) M 8.4 thrust earthquake along the Puerto Rico Trench between Hispaniola and Anegada; (4) M 8.7 thrust along the Puerto Rico Trench between Tortola and Antigua; (5) M 8.0 earthquake from normal faulting on the outer rise north of Anegada. The model output includes extent of onshore flooding, depth and velocity of overland flow, and energy lost by tsunami and hurricane waves as they cross the reef and continue across a shallow subtidal flat to Anegada's north shore. For the medieval overwash, the modeling is most conclusive in testing various explanations for the coral boulders inland of Soldier Wash. The simulated hurricane waves do not wash inland of the storm berm; the height of

    Aim To investigate the usefulness of humerus measurement for sex determination in a sample of medieval skeletons from the Eastern Adriatic Coast. Additional aim was to compare the results with contemporary female population. Methods Five humerus measurements (maximum length, epicondylar width, maximum vertical diameter of the head, maximum and minimum diameter of the humerus at midshaft) for 80 male and 35 female medieval and 19 female contemporary humeri were recorded. Only sufficiently preserved skeletons and those with no obvious pathological or traumatic changes that could affect the measurements were included. For ten samples, analysis of DNA was performed in order to determine sex using amelogenin. Results The initial comparison of men and women indicated significant differences in all five measures (P < 0.001). Discriminant function for sex determination indicated that as much as 85% of cases could be properly categorized, with better results in men (86%) than women (80%). Furthermore, the comparison of the medieval and contemporary women did not show significant difference in any of the measured features. Sex results obtained by anthropological and DNA analysis matched in all 10 cases. Conclusion The results indicate that humerus measurement in Croatian medieval population may be sufficient to determine the sex of the skeleton. Furthermore, it seems that secular changes have not substantially affected contemporary population, suggesting that the results of this study are transferable to contemporary population as well.

    2009-02-01

    This study attempts to address the issue of relative living standards in Portuguese medieval and early 20th century periods. Since the growth of children provides a good measure of environmental quality for the overall population, the skeletal growth profiles of medieval Leiria and early 20th century Lisbon were compared. Results show that growth in femur length of medieval children did not differ significantly from that of early 20th century children, but after puberty medieval adolescents seem to have recovered, as they have significantly longer femora as adults. This is suggestive of greater potential for catch-up growth in medieval adolescents. We suggest that this results from distinct child labor practices, which impact differentially on the growth of Leiria and Lisbon adolescents. Work for medieval children and adolescents were related to family activities, and care and attention were provided by family members. Conversely, in early 20th century Lisbon children were more often sent to factories at around 12 years of age as an extra source of family income, where they were exploited for their labor. Since medieval and early 20th century children were stunted at an early age, greater potential for catch-up growth in medieval adolescents results from exhausting work being added to modern adolescent's burdens of disease and poor diet, when they entered the labor market. Although early 20th century Lisbon did not differ in overall unfavorable living conditions from medieval Leiria, after puberty different child labor practices may have placed modern adolescents at greater risk of undernutrition and poor growth.

    Although the connection between head and stomach and hence the condition known as "gastric headache" was well known to the ancients, it has received little attention since the early 20th century. Herein, we review the teachings of the medieval Persian physicians about the gastric headache along with the related signs, symptoms, types and causes. The medieval Persian scholars adopted the main ideas of the gastric headache from predecessors in the ancient Greece and Rome, added substantial sub-categories and details to the earlier descriptions and therapeutic options. The medieval Persian physicians' contributions to the concept of gastric headache influenced beyond doubt the later accounts of this condition.

    The purpose of this study is to obtain demographic data regarding the medieval population buried at the Yuigahama-minami site in Kamakura, Japan, and to detect a secular trend in the life expectancy of Japanese population over the last several thousand years. The Yuigahama-minami skeletal sample consists of 260 individuals, including 98 subadults (under 20 years old) and 162 adults. A Yuigahama-minami abridged life-table analysis yielded a life expectancy at birth (e0) of 24.0 years for both sexes, a life expectancy at age 15 years (e15) of 15.8 years for males, and an e15 of 18.0 years for females. The reliability of the estimated e0 was confirmed by analysis of the juvenility index. Demographic profiles comparing the Yuigahama-minami series with other skeletal series indicated that both the survivorship curve and life expectancy of the Yuigahama-minami sample are similar to those of the Mesolithic-Neolithic Jomon population, but are far lower than those of the early modern Edo population. These comparisons strongly suggest that life expectancy changed little over the thousands of years between the Mesolithic-Neolithic Jomon and medieval periods, but then improved remarkably during the few hundred years between the medieval period and early modern Edo period. The short-lived tendency of the Yuigahama-minami sample does not contradict the archaeological hypothesis of unsanitary living conditions in medieval Kamakura. This is the first investigation to address the demographic features of a medieval population in Japan, and will help refine our understanding of long-term trends in the demographic profiles of inhabitants of Japan.

    In contrast to investigations on soil variability, electromagnetic induction (EMI) instruments have been used rarely for archaeogeophysical prospection. Nevertheless, the potential of EMI sensors to record simultaneously electrical and magnetic soil properties is a major asset. In non-saline environments the measured apparent electrical conductivity (ECa) mainly relates to soil texture (primarily clay), whereas the apparent magnetic susceptibility (MSa) is often heavily influenced by anthropogenic soil disturbances and iron containing material. The latest generations of multi-receiver EMI sensors allow recording the ECa and MSa of multiple soil volumes simultaneously, enabling the three-dimensional (3D) reconstruction of the natural and anthropogenic soil composition. Using a multi-receiver EMI instrument, we surveyed in detail an area of 8 ha located within a 25 km2 wetland area in the north of Belgium. The ECa data indicated a heterogeneous environment with accumulated peat, sandy outcrops and lacustrine marl. Within these sediments multiple traces of anthropogenic ditch systems were clearly visible. In addition, a number of regularly arranged punctual structures were detected with the MSa measurements. Based on these observations, two excavation trenches were positioned over the most characteristic anomalies to gain detailed insight into the archaeological features and the stratigraphy of the site. It appeared that most structures could be related to a medieval environment composed of ditches and brick fundaments of larger constructions associated with an adjacent monastery. To reconstruct the detected medieval landscape, the multi-layered EMI dataset was combined with the excavation data through an inversion procedure. While from one excavation trench stratigraphical information was used to calibrate this landscape model, geometrically correct profile information was used from the other trench to test the validity of the model. Finally, the multi-layered MSa

    At present, there are numerous millennial-length northern hemisphere reconstructions. However, only a small sub-set utilise just tree-ring data. Despite the theoretical ideal of the multi-proxy approach for producing large scale reconstructions, there still exist many problems with implementing such studies; (1) they generally do not take into account the varying seasonality of the climate signal that each constituent proxy record contains, resulting in a composite reconstruction that is a seasonal melange which is often calibrated to annual temperatures and (2) all non-tree-ring proxy archives contain small to substantial dating uncertainties that at best affords capture of temperature variations at decadal or longer time scales. These two problems conspire against the multi-proxy experiment for the robust attribution of climate forcing and characterizing the full spectrum of natural variability. We suggest that focusing on tree-ring based reconstructions will substantially improve our understanding of past climate variability as they are precisely dated and have the potential to reconstruct warm season temperatures on inter-annual to multi-centennial time scales. We present the development of an updated and expanded collection of published temperature sensitive tree-ring series (both ring-width and ring-density) for the Northern Hemisphere, which can be used not only to improve our understanding of past large-scale temperature changes but also to identify regions where currently too few data exist. Our main goals are; (1) enumerate the unique qualities of ring-width and maximum latewood density chronologies, especially for assessing volcanic forcing and seasonal response; and (2) compare the spatial robustness of gridded reconstructions, especially during the supposed warm medieval period and the more recent, but better represented, Little Ice Age. Currently, large scale single series NH temperature reconstructions do not agree well with climate model output

    This essay challenges the often expressed view that the principles of metals, namely mercury and sulphur, were generally viewed by alchemists as being of a 'metaphysical' character that made them inaccessible to the tools and operations of the laboratory. By examining a number of Arabo-Latin and Latin alchemical texts in circulation before the end of the thirteenth century, the author presents evidence that most alchemists of the period considered mercury and sulphur to be materials subject to techniques of purification in the same way that naturally occurring salts and minerals could be freed of their impurities or dross. The article also points to the immense influence of Avicenna and Albertus Magnus in formulating the theory that mercury and sulphur were compounds of different materials, containing both fixed and unfixed components. Finally, the author briefly examines the relationship between this materialist approach to the principles and the chymical atomism of early modern authors who were deeply aware of medieval alchemical literature.

    Global temperatures are known to have varied over the past 1500 years, but the spatial patterns have remained poorly defined. We used a global climate proxy network to reconstruct surface temperature patterns over this interval. The Medieval period is found to display warmth that matches or exceeds that of the past decade in some regions, but which falls well below recent levels globally. This period is marked by a tendency for La Niña-like conditions in the tropical Pacific. The coldest temperatures of the Little Ice Age are observed over the interval 1400 to 1700 C.E., with greatest cooling over the extratropical Northern Hemisphere continents. The patterns of temperature change imply dynamical responses of climate to natural radiative forcing changes involving El Niño and the North Atlantic Oscillation-Arctic Oscillation.

    Sea surface temperature (SST), salinity, and flux of terrigenous material oscillated on millennial time scales in the Pleistocene North Atlantic, but there are few records of Holocene variability. Because of high rates of sediment accumulation, Holocene oscillations are well documented in the northern Sargasso Sea. Results from a radiocarbondated box core show that SST was {approximately} 1{degree}C cooler than today {approximately} 400 years ago (the Little Ice Age) and 1700 years ago, and {approximately} 1{degree}C warmer than today 1000 years ago (the Medieval Warm Period). Thus, at least some of the warming since the Little Ice Age appears to be part of a natural oscillation. 39 refs., 4 figs., 1 tab.

He made great inroads in the art of translation in the Islamic world. In addition to his own translations, Johannitius put significant effort into training pupils and passing knowledge about translation to succeeding generations. He was also a great writer, compiling over 100 books on different subjects, especially medical. Among his own works, the illustrious Kitab al-Ashr Maqalat fil-Ayn (Ten Treatises on the Eye) contains the oldest known illustration of the structure of the eye. It served as the primary source for Galen's theory of vision and subsequent use by Western scholars. PMID:24913848

    Studies of past human-landscape interactions rely upon the integration of archaeological, biological and geological information within their geographical context. However, detecting the often ephemeral traces of human activities at a landscape scale remains difficult with conventional archaeological field survey. Geophysical methods offer a solution by bridging the gap between point finds and the surrounding landscape, but these surveys often solely target archaeological features. Here we show how simultaneous mapping of multiple physical soil properties with a high resolution multi-receiver electromagnetic induction (EMI) survey permits a reconstruction of the three-dimensional layout and pedological setting of a medieval reclaimed landscape in Flanders (Belgium). Combined with limited and directed excavations, the results offer a unique insight into the way such marginal landscapes were reclaimed and occupied during the Middle Ages. This approach provides a robust foundation for unravelling complex historical landscapes and will enhance our understanding of past human-landscape interactions.

    A paleoseismological study of the medieval Kamenka fortress in the northern part of the Issyk-Kul Lake depression, northern Tien Shan in Kyrgyzstan, revealed an oblique slip thrust fault scarp offsetting the fortification walls. This 700 m long scarp is not related to the 1911 Kebin Earthquake (Ms 8.2) fault scarps which are widespread in the region. As analysis of stratigraphy in a paleoseismic trench and archaeological evidence reveal, it can be assigned to a major twelfth century a.d. earthquake which produced up to 4 m of oblique slip thrusting antithetic to that of the nearby dominant faults. The inferred surface rupturing earthquake apparently caused the fortress destruction and was likely the primary reason for its abandonment, not the Mongolian Tatar invasions as previously thought.

    Geomorphic footprints of past large Himalayan earthquakes are elusive, although they are urgently needed for gauging and predicting recovery times of seismically perturbed mountain landscapes. We present evidence of catastrophic valley infill following at least three medieval earthquakes in the Nepal Himalaya. Radiocarbon dates from peat beds, plant macrofossils, and humic silts in fine-grained tributary sediments near Pokhara, Nepal's second-largest city, match the timing of nearby M > 8 earthquakes in ~1100, 1255, and 1344 C.E. The upstream dip of tributary valley fills and x-ray fluorescence spectrometry of their provenance rule out local sources. Instead, geomorphic and sedimentary evidence is consistent with catastrophic fluvial aggradation and debris flows that had plugged several tributaries with tens of meters of calcareous sediment from a Higher Himalayan source >60 kilometers away.

Accelerator Mass Spectrometer analyzed 14C radiocarbon age constraints from six detrital charcoal samples ranging between 1688 B.C. and A.D. 1152 are consistent with the great medieval earthquake of A.D. 1255 that is interpreted to have produced a minimum observed fault slip of ~5 m in the trench exposure. Recalibration of radiocarbon ages from previous studies at Harmutty, Nameri, and Marha in the eastern Himalaya using Bayesian statistical analyses further substantiates the possibility that the A.D. 1255 earthquake might have ruptured the Himalayan front over a length of ~800 km from ~85.87° to 93.76°E longitudes.

    Memory and dementia are historical ideas that preceded the development of modern neuroscientific, psychogeriatric and medical approaches to aging and cognitive impairment. This article explores the value of such historical ideas in order to understand the discourses and metaphors by which Western thought has individualized memory as the guarantor of rational personhood, while at the same, treating memory decline as a threat to healthy and successful aging. Discussion focuses on the relationship between memory and the body in the classical and medieval ars memoria (the art of memory) and in the early modern philosophies of personhood, particularly the work of John Locke. Conclusions consider the significance of Western culture's history of embodied memory as it moved from cosmic to individual to neurocognitive sites for our wider views about the treatment of dementia.

    Among the first three manuscripts written in Persian, Akhawayni’s Hidayat al-muta’allemin fi al-tibb was the most significant work compiled in the 10th century. Along with the hundreds of chapters on hygiene, anatomy, physiology, symptoms and treatments of the diseases of various organs, there is a chapter on sleep paralysis (night-mare) prior to description and treatment of epilepsy. The present article is a review of the Akhawayni’s teachings on sleep paralysis and of descriptions and treatments of sleep paralysis by the Greek, medieval, and Renaissance scholars. Akhawayni’s descriptions along with other early writings provide insight into sleep paralysis during the Middle Ages in general and in Persia in particular. PMID:22701323

    Geomorphic footprints of past large Himalayan earthquakes are elusive, although they are urgently needed for gauging and predicting recovery times of seismically perturbed mountain landscapes. We present evidence of catastrophic valley infill following at least three medieval earthquakes in the Nepal Himalaya. Radiocarbon dates from peat beds, plant macrofossils, and humic silts in fine-grained tributary sediments near Pokhara, Nepal’s second-largest city, match the timing of nearby M > 8 earthquakes in ~1100, 1255, and 1344 C.E. The upstream dip of tributary valley fills and x-ray fluorescence spectrometry of their provenance rule out local sources. Instead, geomorphic and sedimentary evidence is consistent with catastrophic fluvial aggradation and debris flows that had plugged several tributaries with tens of meters of calcareous sediment from a Higher Himalayan source >60 kilometers away.

  1. What is “colonial” about medieval colonial medicine? Iberian health in global context

    Colonial medicine is a thriving field of study in the history of nineteenth- and twentieth-century medicine. Medicine can be used as a lens to view colonialism in action and as a way to critique colonialism. This article argues that key debates and ideas from that modern field can fruitfully be applied to the Middle Ages, especially for the early empires of Spain and Portugal (mid-fourteenth to mid-sixteenth centuries). The article identifies key modern debates, explores approaches to colonization and colonialism in the Middle Ages and discusses how medieval and modern medicine and healthcare could be compared using colonial and postcolonial discourses. The article ends with three case studies of healthcare encounters in Madeira, Granada and Hispaniola at the end of the fifteenth century. PMID:26550030

    Analysis of enamel hypoplasia frequencies for two medieval populations representing the earliest and latest Christian periods of ancient Nubia reveals important diachronic shifts in childhood stress. The mean frequency for hypoplastic bands among the early Christians is 4.2, while the late Christian sample has a mean frequency of 3.7. In addition, the earlier Christians show a prolongation of hypoplastic occurrences through childhood corresponding to a prolonged period of intensified childhood mortality. The modal time interval between hypoplastic occurrences is also shorter for the early Christian children. A comparison of hypoplasia frequencies by sex also reveals a pattern of considerable interest. Females show both lower frequencies of hypoplasias as well as a delay in onset. The diachronic differences are consistent with other indications from paleopathology and paleodemography that childhood stress decreased in later Christian times. The sex differences suggest that during the infancy and early childhood females were more resilient than their male counterparts.

    Proxy reconstructions suggest that peak global temperature during the past warm interval known as the Medieval Climate Anomaly (MCA, roughly 950-1250 AD) has been exceeded only during the most recent decades. To better understand the origin of this warm period, we use model simulations constrained by data assimilation establishing the spatial pattern of temperature changes that is most consistent with forcing estimates, model physics and the empirical information contained in paleoclimate proxy records. These numerical experiments demonstrate that the reconstructed spatial temperature pattern of the MCA can be explained by a simple thermodynamical response of the climate system to relatively weak changes in radiative forcing combined with a modification of the atmospheric circulation, displaying some similarities with the positive phase of the so-called Arctic Oscillation, and with northward shifts in the position of the Gulf Stream and Kuroshio currents. The mechanisms underlying the MCA are thus quite different from anthropogenic mechanisms responsible for modern global warming.

    Background Historical records suggest that multiple burial sites from the 14th–16th centuries in Venice, Italy, were used during the Black Death and subsequent plague epidemics. Methodology/Principal Findings High throughput, multiplexed real-time PCR detected DNA of seven highly transmissible pathogens in 173 dental pulp specimens collected from 46 graves. Bartonella quintana DNA was identified in five (2.9%) samples, including three from the 16th century and two from the 15th century, and Yersinia pestis DNA was detected in three (1.7%) samples, including two from the 14th century and one from the 16th century. Partial glpD gene sequencing indicated that the detected Y. pestis was the Orientalis biotype. Conclusions These data document for the first time successive plague epidemics in the medieval European city where quarantine was first instituted in the 14th century. PMID:21423736

    The medieval physician, translator and author Abū Zayd Ḥunayn ibn Isḥāq al-'Ibādī, best known in the West as Johannitius, is considered the best translator of Greek texts, particularly medical writings, into Arabic. He made great inroads in the art of translation in the Islamic world. In addition to his own translations, Johannitius put significant effort into training pupils and passing knowledge about translation to succeeding generations. He was also a great writer, compiling over 100 books on different subjects, especially medical. Among his own works, the illustrious Kitab al-Ashr Maqalat fil-Ayn (Ten Treatises on the Eye) contains the oldest known illustration of the structure of the eye. It served as the primary source for Galen's theory of vision and subsequent use by Western scholars.

    2011-01-01

    In recent years, historians of medicine in the Middle Ages have tried to decode narratives of health and illness in their original context, attempting to uncover the meanings they may have had for the original audiences, rather than simply using these narratives to plot disease incidence. This article is a study of health, illness and traumatic injury in the chronicles of Fernão Lopes, who wrote in Portugal in the first half of the fifteenth century, focusing on the events of 1383–5, a period of civil war and foreign invasion. Arguing that Lopes made use of a series of medical ‘emplotments’ to construct his history, this study approaches medieval medicine in as broad a sense as possible engaging with the role of moral and bodily health in a dramatic tale of political ambition and national resurgence.

    A set of fragments of metallic artefacts from the medieval period excavated from Ciudad Real in Spain has been studied. The objects are gilded copper buckles with a champlevé enamelling decoration. The composition of predominantly blue-coloured enamels has been analysed using three non-destructive techniques, SEM-EDAX (scanning electron microscopy coupled with energy-dispersive X-ray analysis), X-ray fluorescence (XRF) and PIXE (particle-induced X-ray emission). Analyses show that Co is responsible for the blue colour. The results of the two techniques are compared, as well as the main components which constitute the enamel. Analyses suggest that Cu is responsible for red colour.

    2015-05-01

    The earliest church murals of the first stone churches in Finland were painted at the time when Christianity had only just become the official faith in the region and the old ethnic religion was still widely practiced. The 'pagan' motifs of these Early Medieval Finnish church murals reflect the complexity of the religious beliefs in this transition phase. The church actively transformed the festivals of the vernacular religion by giving Christian meanings to the symbols and rituals, as well as by replacing the ethnic deities with Christian figures. The solar symbolism and the calendrical motifs of the church murals are interpreted as imagery largely based on the Christianized remnants of the pre-Christian annual festivals. The earliest church murals thus provide important insight into the pre-Christian religious beliefs of late Iron Age Finland. Many of the motifs and symbols represented in the murals are related to the annual fertility cult and the solar goddess as one of its central figures.

  11. Signs and senses: diagnosis and prognosis in early medieval pulse and urine texts.

    PubMed

    Wallis, F

    2000-08-01

    The character of early medieval medical manuscripts makes it difficult to generalize about the nature of medical knowledge in this period. In order to reconstitute one field of medical science, namely diagnosis and prognosis, while avoiding the pitfalls of unjustified generalization, this essay limits itself to reconstructing the understanding of pulse and urine inspection available in a particular place and time: the Italian monastery of Monte Cassino at the end of the first millennium. The available texts reveal little about the rationale behind these bedside techniques; indeed, pulse and urine seem to be signs without any semiotics, any underlying theory. The clue to this paradox is the fact that these texts see pulse and urine as primarily prognostic rather than diagnostic. Prognosis was understood to be analogous to forms of intuition, judgement, revelation, and prophecy that operated outside the logic of causality. Hence a fully rationalized semiotics was not regarded as necessary for effective medical practice.

    The paper presents the results of a reconstruction of the 3D model of a dome and of a medieval fresco, collapsed after an earthquake and now reconstructed in significant portions, to offer to the visitors a possible reconstruction of the lost masterpiece of medieval art. After the earthquake the collapsed dome was replaced by means of a concrete sphere connected with the survived portions of the old dome's timber. The old dome shape and the fresco were virtually reconstructed thanks to a set of historical pictures obtained by Italian, USA and German archives; those images have been calibrated and oriented by using modern digital photogrammetric approach and a realistic 3D model of the old inner surface of the dome has been realised. By using a LiDAR survey the 3D model of the apse and of the dome, has been set up and the boundaries between original and new structures have been reconstructed by visual evidences.The new dome has been virtually erased and the old dome with the fresco 3D model inserted allowing the reconstruction of the apse as it was before the earthquake. This virtual 3D model has been used to realise a 1:1 scale model of the old dome where the restorers fit some parts of the old fresco fragments recovered just after the earthquake, cleaned and classified. The fresco images correctly oriented inside the reconstructed dome have been projected on plane surfaces by using azimuthal orthographic projections of small portions of the dome in order to reduce the geometric deformations and to allow the mosaicking of these small planes onto a spherical surface.

    The early medieval site Thunau am Kamp consists of a hill fort and a settlement with large burial ground at the bank of river Kamp. All these features are under archaeological investigation since many years. The settlement comprises many pit houses, some with stratigraphic order. Every pit house was equipped with at least one cupola oven and/or a hearth or fireplace. Sometimes the entire cupola was preserved. The site was occupied during the 9th and 10th AD according to potshards which seem to indicate two phases: In the older phase ovens were placed in the corner of the houses while during the younger phase they are found in the middle of the wall. In order to increase the archaeomagnetic data base 14 ovens have been sampled. They fill the temporal gap in the data base for Austria around 900 AD. Laboratory treatment included alternation field and thermal demagnetisations as well as rock magnetic experiments. The baked clay with was formed from a loess sediment has preserved stable directions. Apart from one exception the mean characteristic remanent magnetization directions are concentrated around 900 AD on the early medieval part of the directional archaeomagnetic reference curve of Austria (Schnepp & Lanos, GJI, 2006). Using this curve archaeomagnetic dating with RenDate provides ages between 800 and 1100 AD which are in agreement with archaeological dating. In one case archaeomagnetic dating is even more precise. Together with the archaeological age estimates and stratigraphic information the new data have been included into the database of the Austrian curve. It has been recalculated using a new version of RenCurve. The new data confine the curve and its error band considerably in the time interval 800 to 1100 AD. The curve calibration process also provides a probability density distribution for each structure which allows for posterior dating. This refines temporal errors considerably.

    The vanguard that began to question Galenic anatomical dogma originated in northern Italy in the latter half of the thirteenth century, and not coincidentally this was where human dissection was introduced, which in turn eventually fostered the origins of realistic anatomical illustration in the late fifteenth century. With the advent of the printing press and moveable type at this time, printed books began to supersede hand-copied medieval manuscripts, and labor-intensive techniques were soon developed to integrate text and illustrations on the printed page. The same technology was used to pirate the illustrations of prior authors with varying fidelity. Specific medieval and Renaissance anatomical illustrations can often be traced from their inceptions through different stages of development to the final printed images, and then through subsequent pirated versions in various abridgements or other compendia. The most important milestone in the development of anatomy and anatomical illustration was the publication in 1543 by Andreas Vesalii of De humani corporis fabrica (On the Fabric of the Human Body), commonly referred to simply as the Fabrica. With this work, Vesalii succeeded in coordinating a publication production team (author, artists, block cutters, publisher, and typesetters) to achieve an unprecedented integration of scientific discourse, medical illustration, and typography. However, despite Vesalii's valiant efforts to prevent unauthorized duplication, the illustrations from the Fabrica were extensively plagiarized. Although Vesalii found such piracy frustrating and annoying, the long-term effect was to make Vesalii's ideas known to a wider readership and to help solidify his own revolutionary contributions to anatomy.

Parasite eggs, identified as eggs of Opisthorchis felineus, were found in the samples from the pelvic area of a one year old infant buried at the site. Presence of these eggs in the soil samples from the infant's abdomen suggests that he/she was infected with opisthorchiasis and imply consumption of undercooked fish. Ethnographic records collected among the population of the northern part of Western Siberia reveal numerous cases of feeding raw fish to their children. Zeleniy Yar case of opisthorchiasis suggests that this dietary custom has persisted from at least medieval times. PMID:26602874

    In 1912, 68 medieval crania were excavated from a cave at Safed in the eastern Mediterranean and brought to the United Kingdom. It is only recently that these skulls have been studied for evidence of disease. One adult individual demonstrates multiple lesions of the cranial vault, compatible with treponematosis. Radiocarbon dating suggests the year of death to be between 1290-1420 AD. This range equates to the mamluk period, just after the crusades. This is the oldest dated case of treponematosis in the Middle East, and the first to confirm its presence there before the epidemiologically important transatlantic voyage of Christopher Columbus. The finding has significant implications for our understanding of the introduction of the disease to the Middle East and of the medieval diagnosis of ulcerating skin conditions by medical practitioners in the Mediterranean world.

    A panel of cattle bones excavated from the 1000-year-old Viking Fishamble Street site in Dublin was assessed for the presence of surviving mitochondrial DNA (mtDNA). Eleven of these bones gave amplifiable mtDNA and a portion of the hypervariable control region was determined for each specimen. A comparative analysis was performed with control region sequences from five extant Nordic and Irish cattle breeds. The medieval population displayed similar levels of mtDNA diversity to modern European breeds. However, a number of novel mtDNA haplotypes were also detected in these bone samples. In addition, the presence of a putative ancestral sequence at high frequency in the medieval population supports an early post-domestication expansion of cattle in Europe. PMID:10091250

    Premature burial (taphophobia) is an ancient fear, but it became especially common in 18th and 19th century Europe and may have a modern-day counterpart. Examination of a well-documented case from medieval Persia reveals the importance of funeral practices in the risk of actual premature burial and sheds light on the question of why taphophobia became so prevalent in Europe during the early industrial revolution period. The medieval Persian case was attributed to hysterical paralysis (conversion). We discuss the relationship between hysterical paralysis and premature burial more generally and show that although understanding of conversion syndrome remains incomplete, modern knowledge and practices have limited the risk of any similar tragedy today.

    2014-09-01

    Enamel thickness has been linked to functional aspects of masticatory biomechanics and has been demonstrated to be an evolutionary plastic trait, selectively responsive to dietary changes, wear and tooth fracture. European Late Paleolithic and Mesolithic hunter-gatherers mainly show a flat wear pattern, while oblique molar wear has been reported as characteristic of Neolithic agriculturalists. We investigate the relationships between enamel thickness distribution and molar wear pattern in two Neolithic and medieval populations. Under the assumption that dietary and/or non-dietary constraints result in directional selective pressure leading to variations in enamel thickness, we test the hypothesis that these two populations will exhibit significant differences in wear and enamel thickness patterns. Occlusal wear patterns were scored in upper permanent second molars (UM2) of 64 Neolithic and 311 medieval subadult and adult individuals. Enamel thickness was evaluated by microtomography in subsamples of 17 Neolithic and 25 medieval individuals. Eight variables describing enamel thickness were assessed. The results show that oblique molar wear is dominant in the Neolithic sample (87%), while oblique wear affects only a minority (42%) of the medieval sample. Moreover, in the Neolithic molars, where buccolingually directed oblique wear is dominant and greatest enamel lost occurs in the distolingual quadrant, thickest enamel is found where occlusal stresses are the most important-on the distolingual cusp. These results reveal a correlation between molar wear pattern and enamel thickness that has been associated to dietary changes. In particular, relatively thicker molar enamel may have evolved as a plastic response to resist wear.

    The medieval period in Europe was a time of unprecedented social complexity that affected human diet. The diets of certain subgroups-for example, children, women, and the poor-are chronically underrepresented in historical sources from the medieval period. To better understand diet and the distribution of foods during the medieval period, we investigated stable carbon and nitrogen isotope ratios of 30 individuals from Trino Vercellese, Northern Italy (8th-13th c.). Specifically, we examined diet differences between subgroups (males and females, and high- and low-status individuals), and diet change throughout the life course among these groups by comparing dentine and bone collagen. Our results show a diet based on terrestrial resources with input from C(4) plants, which could include proso and/or foxtail millet. Diets of low-status males differ from those of females (both status groups) and of high-status males. These differences develop in adulthood. Childhood diets are similar among the subgroups, but sex- and status-based differences appear in adulthood. We discuss the possibility of cultural buffering and dietary selectivity of females and high-status individuals.

This paper reports the study of mitochondrial DNA (mtDNA) in ancient samples from the 9th-12th centuries originating from the cemeteries discovered in Nitra-Šindolka and Čakajovce, located in western Slovakia (Central Europe). This geographical region is interesting to study because its medieval multi-ethnic population lived in the so-called contact zone of the territory of the Great Moravian and later Hungarian state formations. We described 16 different mtDNA haplotypes in 19 individuals, which belong to the most widespread European mtDNA haplogroups: H, J, T, U and R0. Using comparative statistical and population genetic analyses, we showed the differentiation of the European gene pool in the medieval period. We also demonstrated the heterogeneous genetic characteristics of the investigated population and its affinity to the populations of modern Europe.

  5. Medieval Loess Constraints On the Climate Effect of Dust Aerosols In the Great Plains of North America

    2011-12-01

    Loess deposits in the Great Plains of North America, together with tree ring records, suggest the occurrence of medieval megadroughts within the past millenium when rainfall was below average over several decades. Loess results from the deposition of dust aerosols, created by wind erosion, perhaps following vegetation loss after extended drought. Dust aerosols have been previously shown to exacerbate the absence of rainfall during the twentieth century Dust Bowl, reinforcing the drought and loss of vegetation. Ocean temperatures in the equatorial Pacific make the predominant contribution to hydroclimate variability in this region, but dust may have had an amplifying effect during the medieval drought once the vegetation loss was sufficiently extensive. Here, we describe GCM experiments with dust aerosols created by wind erosion over medieval sources within North America. Our goal is twofold: first, to calculate the climate effect of dust, which is believed to reduce precipitation during the Dust Bowl. Second, we calculate dust deposition for comparison to the observed thickness of loess deposits. This comparison serves as a constraint upon the total dust mobilization and the aerosol effect upon precipitation, both of which depend upon the incompletely known source extent and its productivity.

    Recently reported studies on the medieval mummies in Korea have been regarded as an invaluable source for studying the physical characteristics of medieval Koreans. However, since the reported medieval mummies were re-buried by their descendants without any scientific investigations, the development of a brief, non-invasive investigation technique was desperately needed among the researchers in Korea. In this regard, we tried to apply high-quality multi-detector computed tomography (MDCT) with three-dimensional (3D) reconstructions and multi-planar reformat (MPR) to investigate Korean mummies. In our study, after 1.25 or 2.5mm thin slice axial images were taken, 3D reconstruction and MPR were performed to get more accurate information about internal organs. In this trial, we successfully showed high-quality images for the brain, muscles, bones, heart and liver. During various trials for getting selected organs, we could make the 3D reconstructed images of them. Since we could show that the current MDCT technique could be useful for obtaining high-quality 3D reconstructed images of the internal organs of Korean mummies, this technique will be used in forthcoming similar cases, which could not be investigated using invasive techniques.

    This papers aims to precisely locate the medieval arches of the so called Avignon's (Saint Bénézet) Bridge (South France) and to reconstruct the fluvial dynamics of the Rhone River from Early Medieval Times to the 19th century. Until now, just four remnant arches are still visible (near Avignon) and it is estimated that 22 arches (which represents a total length of approximately 920 meters) were built to span over one of the largest French Rivers. The late roman and early mediaeval dates of several foundation poles extracted from the river bed might suggest the existence of an earlier bridge, though it remains uncertain if any of such an earlier structure was still visible when the first mediaeval bridge was built. The mediaeval bridge was erected from 1177 until 1185 (in less than 10 years), but modified a few decades later when stone arches were erected, thus raising the road level substantially. The structure of the bridge being vulnerable, seasonal floods proved a neverending threat and cause of damage which was frequently repaired with masonry or wood. Final abandon of the edifice could be placed in the late 1660s - Early 1670s according to historical sources. Questions arose about the location of the "lost arches" and evident flood events dated back to the Little Ice Age (e.g. 1500 to 1850) could be responsible of the partial destruction of the bridge. Few archaeological, architectural, historical and palaeoenvironmental works have been undertaken in order to determine the precise shape of the Saint Bénézet Bridge at certain stages of its history. Since 2010, a joint team composed by laboratories affiliated to the French Public Research Centre (CNRS) and to Universities of Avignon and of Aix-Marseille 1 is trying to link the different phases of constructions/destructions of the monument with the fluvial dynamics of the Rhone River for the concerned period (ANR PAVAGE). The geoarchaeological approach adopted comprises bathymetric surveys (SONAR and

    Objectives This work was designed to adapt Geographical Information System-based spatial analysis to the study of historical epidemics. We mapped "plague" deaths during three epidemics of the early 15th century, analyzed spatial distributions by applying the Kulldorff's method, and determined their relationships with the distribution of socio-professional categories in the city of Dijon. Materials and Methods Our study was based on a database including 50 annual tax registers (established from 1376 to 1447) indicating deaths and survivors among the heads of households, their home location, tax level and profession. The households of the deceased and survivors during 6 years with excess mortality were individually located on a georeferenced medieval map, established by taking advantage of the preserved geography of the historical center of Dijon. We searched for clusters of heads of households characterized by shared tax levels (high-tax payers, the upper decile; low-tax payers, the half charged at the minimum level) or professional activities and for clusters of differential mortality. Results High-tax payers were preferentially in the northern intramural part, as well as most wealthy or specialized professionals, whereas low-tax payers were preferentially in the southern part. During two epidemics, in 1400–1401 and 1428, areas of higher mortality were found in the northern part whereas areas of lower mortality were in the southern one. A high concentration of housing and the proximity to food stocks were common features of the most affected areas, creating suitable conditions for rats to pullulate. A third epidemic, lasting from 1438 to 1440 had a different and evolving geography: cases were initially concentrated around the southern gate, at the confluence of three rivers, they were then diffuse, and ended with residual foci of deaths in the northern suburb. Conclusion Using a selected historical source, we designed an approach allowing spatial analysis of

    Recent studies have indicated some evidence for a link between climate variability and plague (Yersinia pestis) dynamics in Central Asia and during most of the 20th century. An intensification of plague outbreaks via population peaks in its host-species, the great gerbil (Rhombomys opimus) and its fleas (Xenopsylla spp) has been found to occur during periods of warmer spring and wetter summer climate. This is important, as human epidemics of plague ultimately originate in its wildlife reservoirs. Given the fact that Medieval Europe was strongly devastated by the Black Death - the second pandemic after the Justinian plague ~540AD, and that the worldwide highest quality and quantity of climate proxy data exist for Europe, we here present, for the first time, a holistic approach to enhance understanding of the mid-14th century Black Death. This is of primary importance not only for medical/epidemiological research, but also for other scientific communities, because the Black Death disease had a sustainable impact on the socio-economic development, culture, art, and religion of Medieval Europe. Palaeoclimatic records of annually resolved European temperature and drought variability are compiled, a high-resolution time-series of anthropogenic deforestation is utilized, documentary archives of socio-economic relevance are considered, and the animal-born plague bacterium is placed in the ecological web. Considering the European/North Atlantic sector and the last millennium, periods of high solar radiation and reduced volcanic activity shift the North Atlantic Oscillation into a generally positive mode, yielding towards warmer temperatures and an intensification of the hydrological cycle. We now argue that increased internal circulation resulted in an overall wetter and warmer climate ~1350AD, which most likely was able to promote the prevalence of existing and widespread Yersinia pestis bacillus. Resulting outbreaks of bubonic plague could have been also supported by the

    Medieval Climate Anomaly (MCA) terrestrial proxy records (speleothem, NW Scotland; tree rings, Morocco) from close to the centres of action of the winter North Atlantic Oscillation (NAO) indicate that the MCA was characterized by a pervasive positive phase of the NAO(1). Spatial gradients across Europe in this MCA synoptic climatological interpretation were analyzed using the Proxy Surrogate Reconstruction approach based on general circulation model simulations. Changes in pervasive NAO phase result in synoptic shifts in surface pressure, wind fields and precipitation. It is hypothesized that these NAO changes are associated with oceanic responses/feedbacks including upwelling intensity and heat transport via the Atlantic Meridional Overturning Circulation (AMOC). Positive (negative) phases of the NAO are associated with enhanced (reduced) AMOC. We review high quality palaeoceanographic data from the North Atlantic covering the last 1000 years to test this hypothesis. These data include proxies for sea surface temperature, bottom water temperature, sea ice cover, upwelling intensity and reconstructions of ocean hydrographic variability, including Gulf Stream outflow, North Atlantic Deep Water return flow and the position of the oceanic Polar Front. Palaeoceanographic data are consistent with the hypothesis that the MCA (Little Ice Age, LIA) was characterized by more (less) intense AMOC. However, there are multiple datasets, including the Na ion ice core proxy from the Greenland Ice Sheet(2), that indicate enhanced storminess across the North Atlantic during the LIA. These data conflict with the hypothesis in that enhanced winter storminess (cyclone frequency) should correspond to the NAO positive rather than negative phase. A possible explanation of this problem has been provided by ensemble simulations of the cyclone-resolving Climate Community System Model (CCSM) coupled ocean-atmosphere general circulation model for the Maunder Minimum (LIA)(3). These indicate

    At the beginning of the Medieval Climate Anomaly, in the ninth and tenth century, the medieval eastern Roman empire, more usually known as Byzantium, was recovering from its early medieval crisis and experiencing favourable climatic conditions for the agricultural and demographic growth. Although in the Balkans and Anatolia such favourable climate conditions were prevalent during the eleventh century, parts of the imperial territories were facing significant challenges as a result of external political/military pressure. The apogee of medieval Byzantine socio-economic development, around AD 1150, coincides with a period of adverse climatic conditions for its economy, so it becomes obvious that the winter dryness and high climate variability at this time did not hinder Byzantine society and economy from achieving that level of expansion. Soon after this peak, towards the end of the twelfth century, the populations of the Byzantine world were experiencing unusual climatic conditions with marked dryness and cooler phases. The weakened Byzantine socio-political system must have contributed to the events leading to the fall of Constantinople in AD 1204 and the sack of the city. The final collapse of the Byzantine political control over western Anatolia took place half century later, thus contemporaneous with the strong cooling effect after a tropical volcanic eruption in AD 1257. We suggest that, regardless of a range of other influential factors, climate change was also an important contributing factor to the socio-economic changes that took place in Byzantium during the Medieval Climate Anomaly. Crucially, therefore, while the relatively sophisticated and complex Byzantine society was certainly influenced by climatic conditions, and while it nevertheless displayed a significant degree of resilience, external pressures as well as tensions within the Byzantine society more broadly contributed to an increasing vulnerability in respect of climate impacts.

    In the Northern Hemisphere, most mountain glaciers experienced their largest extent in the last millennium during the Little Ice Age (1450 to 1850 CE, LIA), a period marked by colder hemispheric temperatures than the Medieval Climate Anomaly (950 to 1250 CE, MCA), a period which coincided with glacier retreat. Here, we present a new moraine chronology based on (36)Cl surface exposure dating from Lyngmarksbræen glacier, West Greenland. Consistent with other glaciers in the western Arctic, Lyngmarksbræen glacier experienced several advances during the last millennium, the first one at the end of the MCA, in ~1200 CE, was of similar amplitude to two other advances during the LIA. In the absence of any significant changes in accumulation records from South Greenland ice cores, we attribute this expansion to multi-decadal summer cooling likely driven by volcanic and/or solar forcing, and associated regional sea-ice feedbacks. Such regional multi-decadal cold conditions at the end of the MCA are neither resolved in temperature reconstructions from other parts of the Northern Hemisphere, nor captured in last millennium climate simulations.

    Nine burials excavated from the Magdalen Hill Archaeological Research Project (MHARP) in Winchester, UK, showing skeletal signs of lepromatous leprosy (LL) have been studied using a multidisciplinary approach including osteological, geochemical and biomolecular techniques. DNA from Mycobacterium leprae was amplified from all nine skeletons but not from control skeletons devoid of indicative pathology. In several specimens we corroborated the identification of M. leprae with detection of mycolic acids specific to the cell wall of M. leprae and persistent in the skeletal samples. In five cases, the preservation of the material allowed detailed genotyping using single-nucleotide polymorphism (SNP) and multiple locus variable number tandem repeat analysis (MLVA). Three of the five cases proved to be infected with SNP type 3I-1, ancestral to contemporary M. leprae isolates found in southern states of America and likely carried by European migrants. From the remaining two burials we identified, for the first time in the British Isles, the occurrence of SNP type 2F. Stable isotope analysis conducted on tooth enamel taken from two of the type 3I-1 and one of the type 2F remains revealed that all three individuals had probably spent their formative years in the Winchester area. Previously, type 2F has been implicated as the precursor strain that migrated from the Middle East to India and South-East Asia, subsequently evolving to type 1 strains. Thus we show that type 2F had also spread westwards to Britain by the early medieval period. PMID:23638071

    The Late Medieval Period was a decisive period in the history of medicine. It was then that medical education was integrated into the universities that were coming into existence and when medicine made its transition from a menial trade to a regulated profession with a statutory basis of learning and graduation. It was also then that the necessities of understanding the fabric of the body was realized; for the first time in history, the study of anatomy and of human dissection were incorporated into the medical curriculum. This was a defining change whose subsequent expansion and evolution would bring about the study of function (physiology) and changes in disease (pathology). Few advances were made in the study of the kidney, which was considered part of the venous circulation, whose function was subservient to that of nutrition in eliminating excess fluid. Uroscopy flourished and reached unrealistic levels of dominance in the diagnosis, treatment, and prognostication of any and all diseases, especially in the hands of quacks and charlatans. Alchemy, a mysterious pseudo-science, blossomed into a discipline that nurtured experimentation and laid the rudimentary foundations of scientific study, chemistry, and pharmacology. It was also then that surgery took form as a specialty that actually provided much of the medical care of the period including that of the principal diseases of the kidney, obstruction and calculi, and thereby laid the foundations of what in time would become urology.

    Anatomy has a long history that started with dissection of animals and then expanded and flourished thanks to dissections performed on human bodies. Artists had a crucial role in uncovering the secrets of human anatomy. While most studies have focused on the influence of famous Renaissance artists on human anatomy studies, the anatomical drawings by pre-Renaissance artists and local craftsmen have remained in their shadow. One of the most popular artistic genres in which complete or parts of human skeletons appear is the Dance of Death (Danse Macabre). This article is an anthropological study of two medieval Dance of Death frescoes that are unusual in being relatively early as well as accurately datable. A comparative morphological analysis of the two late 15th century works present in Istria has been conducted. The two works were painted by two local masters and show how the artists filled the gaps in their knowledge of human anatomy mostly with insights into animal bones and imagination. Their artworks, even though only 16 years apart, demonstrate substantial differences in the representation of the skeletons. The article argues that the history of medicine and of art could make good use of osteology and physical anthropology in attempts to define and understand how anatomical knowledge developed among pre-Renaissance and post-Renaissance artists and local people.

    To date, no estimates of the long-term effect of cranial vault fractures on the risk of dying have been generated from historical or prehistoric skeletons. Excess mortality provides a perspective on the efficacy of modern treatment, as well as the human cost of cranial injuries largely related to interpersonal violence in past populations. Three medieval to early modern Danish skeletal samples are used to estimate the effect of selective mortality on males with cranial vault injuries who survived long enough for bones to heal. The risk of dying for these men was 6.2 times higher than it was for their uninjured counterparts, estimated through a simulation study based on skeletal observations. That is about twice the increased risk of dying experienced by modern people with traumatic brain injuries. The mortality data indicate the initial trauma was probably often accompanied by brain injury. Although the latter cannot be directly observed in skeletal remains, it can be inferred through the relative risks of dying. The ability to identify the effects of selective mortality in this skeletal sample indicates it must be taken into account in paleopathological research. The problem is analogous to extrapolating from death register data to modern communities, so epidemiological studies based on mortality data have the same inherent possibility of biases as analyses of ancient skeletons.

    The climatic mechanisms driving the shift from the Medieval Warm Period (MWP) to the Little Ice Age (LIA) in the North Atlantic region are debated. We use cosmogenic beryllium-10 dating to develop a moraine chronology with century-scale resolution over the last millennium and show that alpine glaciers in Baffin Island and western Greenland were at or near their maximum LIA configurations during the proposed general timing of the MWP. Complimentary paleoclimate proxy data suggest that the western North Atlantic region remained cool, whereas the eastern North Atlantic region was comparatively warmer during the MWP—a dipole pattern compatible with a persistent positive phase of the North Atlantic Oscillation. These results demonstrate that over the last millennium, glaciers approached their eventual LIA maxima before what is considered the classic LIA in the Northern Hemisphere. Furthermore, a relatively cool western North Atlantic region during the MWP has implications for understanding Norse migration patterns during the MWP. Our results, paired with other regional climate records, point to nonclimatic factors as contributing to the Norse exodus from the western North Atlantic region. PMID:26665173

    2010-06-01

    In the 1480s Dominican humanist Filippo de' Barbieri published an illustration of a supposedly ancient female seer called the 'Sybilla Chimica', whose prophetic text repeated the words of the ninth-century astrologer Abu Ma'shar. In tracing the origins of Barbieri's astrological Sibyl, this article examines three sometimes interlocking traditions: the attribution of an ante-diluvian history to the science of the stars, the assertion of astrology's origins in divine revelation, and the belief in the ancient Sibyls' predictions of the birth of Christ and other Christian truths. Medieval authors from the twelfth century on began to cite these traditions together, thereby simultaneously authorizing the use of astrology to predict religious changes and blurring the categories of natural and supernatural as applied to human understanding. This blending of astrology and prophecy appears notably in works by such authors as John of Paris, John of Legnano, Johannes Lichtenberger, and Marsilio Ficino. Ultimately the trajectory that produced Barbieri's astrological Sibyl would lead to a wave of astrological apocalyptic predictions in the sixteenth and seventeenth centuries, as well as to the harnessing of astrology for the defense of the faith in the form of an astrological natural theology, sacralizing science as well as nature.

  2. Social inequality and death as illustrated in late-medieval death dances.

    Mackenbach, J P

    1995-01-01

    Late-medieval murals and books of the then-popular "dances of death" usually represented the living according to their social standing. These works of art thus provide an interesting opportunity to study the relationship between social inequality and death as it was perceived by the works' commissioners or executers. The social hierarchy in these dances of death is mostly based on the scheme of the three orders of the feudal society; variations relate to the inclusion of female characters, new occupations, and non-Christian characters. Many dances of death contain severe judgments on highplaced persons and thus seem to be expressions of a desire for greater social equality. However, a more thorough analysis reveals that the equality of all before death that these dances of death proclaimed held nothing for the poor but only threatened the rich. Because of a lack of reliable data, it is not yet completely clear whether during the late Middle Ages all were indeed equally at risk for premature mortality. Available evidence, however, suggests that the clergy and nobility actually had a higher life expectancy than people placed lower in the social hierarchy. Despite modern changes in the perception of, and knowledge about, social inequality and mortality, these dances of death still capture the imagination, and they suggest that the phenomenon of socioeconomic inequalities in mortality could be used more to emphasize contemporary moral messages on social inequality.

    In the Northern Hemisphere, most mountain glaciers experienced their largest extent in the last millennium during the Little Ice Age (1450 to 1850 CE, LIA), a period marked by colder hemispheric temperatures than the Medieval Climate Anomaly (950 to 1250 CE, MCA), a period which coincided with glacier retreat. Here, we present a new moraine chronology based on 36Cl surface exposure dating from Lyngmarksbræen glacier, West Greenland. Consistent with other glaciers in the western Arctic, Lyngmarksbræen glacier experienced several advances during the last millennium, the first one at the end of the MCA, in ~1200 CE, was of similar amplitude to two other advances during the LIA. In the absence of any significant changes in accumulation records from South Greenland ice cores, we attribute this expansion to multi-decadal summer cooling likely driven by volcanic and/or solar forcing, and associated regional sea-ice feedbacks. Such regional multi-decadal cold conditions at the end of the MCA are neither resolved in temperature reconstructions from other parts of the Northern Hemisphere, nor captured in last millennium climate simulations.

    Sex determination based on discriminant function analysis of skeletal measurements is probably the most effective method for assessment of sex in archaeological and contemporary populations due to various reasons, but it also suffers from limitations such as population specificity. In this paper standards for sex assessment from the femur and tibia in the medieval Irish population are presented. Six femoral and six tibial measurements obtained from 56 male and 45 female skeletons were subjected to discriminant function analysis. Average accuracies obtained by this study range between 87.1 and 97%. The highest level of accuracy (97%) was achieved when using combined variables of the femur and tibia (maximum diameter of femoral head and circumference at tibial nutrient foramen), as well as two variables of the tibia (proximal epiphyseal breadth and circumference at nutrient foramen). Discriminant functions using a single variable provided accuracies between 87.1 and 96% with the circumference at the level of the tibial nutrient foramen providing the best separation. High accuracy rates obtained by this research correspond to the data recorded in other studies thus confirming the importance of discriminant function analysis in assessment of sex in both archaeological and forensic contexts.

These include large temperature excursions during the Little Ice Age (???1400-1900 AD) and the Medieval Warm Period (???800-1300 AD) possibly related to changes in the strength of North Atlantic thermohaline circulation (THC). Evidence is presented for a long period of sustained regional and North Atlantic-wide warmth with low-amplitude temperature variability between ???450 and 1000 AD. In addition to centennial-scale temperature shifts, the existence of numerous temperature maxima between 2200 and 250 years BP (average ???70 years) suggests that multi-decadal processes typical of the North Atlantic Oscillation (NAO) are an inherent feature of late Holocene climate. However, late 19th and 20th century temperature extremes in Chesapeake Bay associated with NAO climate variability exceeded those of the prior 2000 years, including the interval 450-1000 AD, by 2-3??C, suggesting anomalous recent behavior of the climate system. ?? 2002 Elsevier Science B.V.

The social hierarchy in these dances of death is mostly based on the scheme of the three orders of the feudal society; variations relate to the inclusion of female characters, new occupations, and non-Christian characters. Many dances of death contain severe judgments on highplaced persons and thus seem to be expressions of a desire for greater social equality. However, a more thorough analysis reveals that the equality of all before death that these dances of death proclaimed held nothing for the poor but only threatened the rich. Because of a lack of reliable data, it is not yet completely clear whether during the late Middle Ages all were indeed equally at risk for premature mortality. Available evidence, however, suggests that the clergy and nobility actually had a higher life expectancy than people placed lower in the social hierarchy. Despite modern changes in the perception of, and knowledge about, social inequality and mortality, these dances of death still capture the imagination, and they suggest that the phenomenon of socioeconomic inequalities in mortality could be used more to emphasize contemporary moral messages on social inequality.

    Laser-induced breakdown spectroscopy (LIBS) technique is expected to be one of the most preferred techniques in archaeology research since it does not disrupt the structural and chemical form of archaeological samples, and it is considered virtually nondestructive analysis method. In this work, LIBS is used for analyses of glaze, paint, and clay of medieval ceramics collected from East Plain Cilicia, Osmaniye Province during archaeological survey. Transparent glazed and colour-painted ceramics of the Islam and Byzantine pottery traditions are analysed to detect distinctive and common features of the chemical compositions of their glazes. The spectral lines of Islamic and Byzantine glazes indicate that their structures are same. However, strontium (Sr) is determined in the transparent glaze of Islamic ceramics. Elemental composition and homogeneity of paint on one of the sample are determined by LIBS analysis. Colour changes are related with composition differences of the paint content in the archaeological ceramic. In addition, the clay classification of archaeological ceramics taken from the Yapılıpınar mounds, Taşlıhöyük mounds, and Örenşehir ancient sites is done using PCA and PLS-DA chemometric techniques. According to the results of the classification, Yapılıpınar mounds terracotta ceramics differ from those of Taşlıhöyük and Örenşehir ancient sites.

  8. Cranial vault trauma and selective mortality in medieval to early modern Denmark

    To date, no estimates of the long-term effect of cranial vault fractures on the risk of dying have been generated from historical or prehistoric skeletons. Excess mortality provides a perspective on the efficacy of modern treatment, as well as the human cost of cranial injuries largely related to interpersonal violence in past populations. Three medieval to early modern Danish skeletal samples are used to estimate the effect of selective mortality on males with cranial vault injuries who survived long enough for bones to heal. The risk of dying for these men was 6.2 times higher than it was for their uninjured counterparts, estimated through a simulation study based on skeletal observations. That is about twice the increased risk of dying experienced by modern people with traumatic brain injuries. The mortality data indicate the initial trauma was probably often accompanied by brain injury. Although the latter cannot be directly observed in skeletal remains, it can be inferred through the relative risks of dying. The ability to identify the effects of selective mortality in this skeletal sample indicates it must be taken into account in paleopathological research. The problem is analogous to extrapolating from death register data to modern communities, so epidemiological studies based on mortality data have the same inherent possibility of biases as analyses of ancient skeletons.

    In the Northern Hemisphere, most mountain glaciers experienced their largest extent in the last millennium during the Little Ice Age (1450 to 1850 CE, LIA), a period marked by colder hemispheric temperatures than the Medieval Climate Anomaly (950 to 1250 CE, MCA), a period which coincided with glacier retreat. Here, we present a new moraine chronology based on 36Cl surface exposure dating from Lyngmarksbræen glacier, West Greenland. Consistent with other glaciers in the western Arctic, Lyngmarksbræen glacier experienced several advances during the last millennium, the first one at the end of the MCA, in ~1200 CE, was of similar amplitude to two other advances during the LIA. In the absence of any significant changes in accumulation records from South Greenland ice cores, we attribute this expansion to multi-decadal summer cooling likely driven by volcanic and/or solar forcing, and associated regional sea-ice feedbacks. Such regional multi-decadal cold conditions at the end of the MCA are neither resolved in temperature reconstructions from other parts of the Northern Hemisphere, nor captured in last millennium climate simulations.

    Anatomy has a long history that started with dissection of animals and then expanded and flourished thanks to dissections performed on human bodies. Artists had a crucial role in uncovering the secrets of human anatomy. While most studies have focused on the influence of famous Renaissance artists on human anatomy studies, the anatomical drawings by pre-Renaissance artists and local craftsmen have remained in their shadow. One of the most popular artistic genres in which complete or parts of human skeletons appear is the Dance of Death (Danse Macabre). This article is an anthropological study of two medieval Dance of Death frescoes that are unusual in being relatively early as well as accurately datable. A comparative morphological analysis of the two late 15th century works present in Istria has been conducted. The two works were painted by two local masters and show how the artists filled the gaps in their knowledge of human anatomy mostly with insights into animal bones and imagination. Their artworks, even though only 16 years apart, demonstrate substantial differences in the representation of the skeletons. The article argues that the history of medicine and of art could make good use of osteology and physical anthropology in attempts to define and understand how anatomical knowledge developed among pre-Renaissance and post-Renaissance artists and local people.

    The rapid Arab-Islamic conquest during the early Middle Ages led to major political and cultural changes in the Mediterranean world. Although the early medieval Muslim presence in the Iberian Peninsula is now well documented, based in the evaluation of archeological and historical sources, the Muslim expansion in the area north of the Pyrenees has only been documented so far through textual sources or rare archaeological data. Our study provides the first archaeo-anthropological testimony of the Muslim establishment in South of France through the multidisciplinary analysis of three graves excavated at Nimes. First, we argue in favor of burials that followed Islamic rites and then note the presence of a community practicing Muslim traditions in Nimes. Second, the radiometric dates obtained from all three human skeletons (between the 7th and the 9th centuries AD) echo historical sources documenting an early Muslim presence in southern Gaul (i.e., the first half of 8th century AD). Finally, palaeogenomic analyses conducted on the human remains provide arguments in favor of a North African ancestry of the three individuals, at least considering the paternal lineages. Given all of these data, we propose that the skeletons from the Nimes burials belonged to Berbers integrated into the Umayyad army during the Arab expansion in North Africa. Our discovery not only discusses the first anthropological and genetic data concerning the Muslim occupation of the Visigothic territory of Septimania but also highlights the complexity of the relationship between the two communities during this period.

    2016-04-01

    Sex determination based on discriminant function analysis of skeletal measurements is probably the most effective method for assessment of sex in archaeological and contemporary populations due to various reasons, but it also suffers from limitations such as population specificity. In this paper standards for sex assessment from the femur and tibia in the medieval Irish population are presented. Six femoral and six tibial measurements obtained from 56 male and 45 female skeletons were subjected to discriminant function analysis. Average accuracies obtained by this study range between 87.1 and 97%. The highest level of accuracy (97%) was achieved when using combined variables of the femur and tibia (maximum diameter of femoral head and circumference at tibial nutrient foramen), as well as two variables of the tibia (proximal epiphyseal breadth and circumference at nutrient foramen). Discriminant functions using a single variable provided accuracies between 87.1 and 96% with the circumference at the level of the tibial nutrient foramen providing the best separation. High accuracy rates obtained by this research correspond to the data recorded in other studies thus confirming the importance of discriminant function analysis in assessment of sex in both archaeological and forensic contexts.

    The climatic mechanisms driving the shift from the Medieval Warm Period (MWP) to the Little Ice Age (LIA) in the North Atlantic region are debated. We use cosmogenic beryllium-10 dating to develop a moraine chronology with century-scale resolution over the last millennium and show that alpine glaciers in Baffin Island and western Greenland were at or near their maximum LIA configurations during the proposed general timing of the MWP. Complimentary paleoclimate proxy data suggest that the western North Atlantic region remained cool, whereas the eastern North Atlantic region was comparatively warmer during the MWP-a dipole pattern compatible with a persistent positive phase of the North Atlantic Oscillation. These results demonstrate that over the last millennium, glaciers approached their eventual LIA maxima before what is considered the classic LIA in the Northern Hemisphere. Furthermore, a relatively cool western North Atlantic region during the MWP has implications for understanding Norse migration patterns during the MWP. Our results, paired with other regional climate records, point to nonclimatic factors as contributing to the Norse exodus from the western North Atlantic region. PMID:26665173

    As can be made evident chiefly by their comparative numerical examination, the Egyptian pyramids (the step pyramids being excluded for the present purpose) have been, from the beginning up to the Egyptian fashion in early Imperial Rome, designed and built with the additional intention of physically manifesting a volume of pi x 10k x (average value) 0.96824 cm3, where k is either a positive integer or zero, and where pi is a short product, following very restrictive formation rules which to some extent are traceable in the papyrus Rhind, of prime numbers. Conceptually (but not really as to the Hin at least) this establishes the capacity units 1 [2]Heqat = 9682.4 cm3 and 1 Hin = 484.12 cm3 already for the Old Kingdom. It is shown further that the Attic Medimnos as introduced in the course of finishing Solon's reforms is identical with the Egyptian volume system's standard unification: pisigma = 2 x 3 x 5 x 7 x 11 x 23, and k = 0, so that 1 Medimnos = about 51443 cm3. Accordingly and by means of some adjacent considerations a Kotyle / Cotyla of 269 cm3 +/- 1 cm3 is established for the Hellenistic, early Arabic, and Medieval Latin medicine. PMID:16425844

    Recently, a number of mummified brains obtained from the remains of medieval Joseon Koreans have been subjected to biological investigations. Although the morphology of the organs had been perfectly maintained on gross examination, we still do not know how well biomolecules such as DNA were preserved. In the present study, the preservation status of remnant DNA in mummified brain tissue was determined by means of comparisons with corresponding DNA taken from the femurs of the same subjects. Quantifiler analysis revealed that DNA from the mummified brain was less fragmented than that contained in the femurs. The better preservation status of the brain DNA was shown also in MiniFiler assays: the number of short tandem repeat (STR) locus profiles for the mummified brain was far higher than in the case of the femur bones. In the case of the mtDNA analysis, longer DNA fragments (821 bp) could be successfully amplified with brain samples, whereas only shorter PCR amplicons (221-263 bp) were seen with the femur samples. Indeed mummified brain tissue, if discovered in amounts suitable for ancient DNA analysis, promises to be the preferred source for genetic analysis of individuals from pre-modern Korean tombs.

    Yellow decoration effects in stained glasses using silver staining were first applied in the beginning of the 14th century. The glass piece being decorated was usually painted on its side intended to be facing the exterior environment, and then fired to temperatures between 500 and 650 °C, resulting in colours ranging from pale lemon to deep orange. Stained glass fragments painted by this process and belonging to the Convento de Cristo, in Tomar, Portugal, were characterised using micro-PIXE, and complemented with other analytical techniques, namely UV-Vis spectroscopy and XRF. Preliminary analysis showed that a mixture of Ag and Cu was used for the production of the yellow staining. In order to understand this staining process and the influence of the firing temperature on the resulting colours, several soda and potash glasses with compositions similar to those of medieval glasses were produced and characterised. The role played by the addition of Cu in the final colours was also investigated.

    In the 1480s Dominican humanist Filippo de' Barbieri published an illustration of a supposedly ancient female seer called the 'Sybilla Chimica', whose prophetic text repeated the words of the ninth-century astrologer Abu Ma'shar. In tracing the origins of Barbieri's astrological Sibyl, this article examines three sometimes interlocking traditions: the attribution of an ante-diluvian history to the science of the stars, the assertion of astrology's origins in divine revelation, and the belief in the ancient Sibyls' predictions of the birth of Christ and other Christian truths. Medieval authors from the twelfth century on began to cite these traditions together, thereby simultaneously authorizing the use of astrology to predict religious changes and blurring the categories of natural and supernatural as applied to human understanding. This blending of astrology and prophecy appears notably in works by such authors as John of Paris, John of Legnano, Johannes Lichtenberger, and Marsilio Ficino. Ultimately the trajectory that produced Barbieri's astrological Sibyl would lead to a wave of astrological apocalyptic predictions in the sixteenth and seventeenth centuries, as well as to the harnessing of astrology for the defense of the faith in the form of an astrological natural theology, sacralizing science as well as nature.

    In course of the archaeological survey of Ayasuluk/Ephesos region (Turkey), a shaft well situated at the area of an extensive medieval bathing complex was excavated. In the stratum corresponding to the reign Mehmed II the well-preserved skeletons of two humans, an equine and a canine were recovered. Anthropological analysis of the human skeletons indentified two males aged 22 (± 3) and 36 (± 5) years. The skeleton of the younger individual showed signs of various antemortal conditions, including a well-healed fraction of right arc of the fifth lumbar vertebra, and a marked asymmetry of the shoulder joints. The older individual exhibited significant peri/postmortem injuries at the elbows, with evident signs of peeling and external burning. Also, the few elements of the cranium recovered showed also indications of burning. Archaeozoological characterization of the complete skeletons of the equine and canine established evidence of well cared-for animals of high value. The time of disposal of this group coincides with uprising of the formerly ruling Aydnoullar clan against the Ottomans in power. The human individuals recovered from the well may have been members of Aydnoullar tribe or men in service of the latter, suffering severe torture and/or mutilation for siding with the rebels after defeat.

    The study is focused on villages that are abandoned throughout the Basilicata from the 13th to the 15th century (Masini 1998), which is an emblematic case of abandonment of settlements in Late Middle Ages, which was a very common phenomenon throughout the whole Europe, attracting the interest of several historians and archaeologists (Demians d'Archimbaud 2001) The aim of the present study is to offer a contribution to knowledge of the medieval Basilicata's landscapes and settlement's dynamics with a multidisciplinary approach, derived from the rescue archeology: we have integrated the documentary sources with the use of spatial analysis and predictive models (Danese et al. 2009). The preventive archeology was born to conciliate the protection of archeological heritage, in evidence and potential, with the needs of urban design and planning. It is of fundamental importance, for a reliable evaluation of archaeological potential (identifying invisible traces) to use innovative diagnostic technologies: geophysical prospections, remote sensing (Lasaponara & Masini 2010; Lasaponara et al. 2016) and spatial analysis for the creation of predictive models. The latter are used to accomplish operational purposes but also for the historical landscape reconstruction (Danese et al. 2013; 2014). They contribute to analyse settlements and their dynamics on the basis of definite method and parameters. Thanks to predictive models it is possible, in fact, to start off by information of well-known archeological sites and use this knowledge as an empiric test for understand which elements have influenced their localization in the space. The relationships among natural environment, social context and position site are analysed in order to make clear the rules of settlement. These rules are then used into the model (Podobnikar et al. 2001). In this work the employed methodology is Spatial Analysis, in order to subdivide the territory based on its importance respect to a given function

    I realize after having gone over this material that I have done a sort of deconstruction of Dante's Divine Comedy which putatively attempts to raise the human vision to transcendent heights and to focus love on the love of God, but which along the way indulges in the very human aspects of pity, compassion, music, poetry, and the other arts, as well as reason and puzzlement. In this sense the poem is also an exposition of the value of the higher human faculties, which contrasts at times rather vividly with the apparently harsh autocratic fates that are assigned to some characters--who do not seem quite deserving of what is inflicted upon them. Here we have a collision between absolute faith in the judgment of God and human reason and compassion which sometimes seems to be unable to justify these judgments. In spite of the fact that Dante is trying to adhere to orthodox theology throughout, it is clear that his poetic soul has great difficulty in avoiding the depiction of characters for whom he has a secret sympathy. The central point of this study of The Divine Comedy is to emphasize how Dante, almost in spite of himself, expressed empathy and understanding for a variety of unfortunates either in the Inferno or in the Purgatorio. Virgil even scolds him for his compassion, arguing that God's justice is always correct and if God is angry at someone and punishes him or her, Dante should also be angry and not compassionate. Dante tries, but he cannot quite manage to do it. Translated into modern terminology, we can learn from this report of a medieval "psychoanalysis" an important lesson in our clinical work. Rigid adherence to rules such as those Freud himself proclaimed (although he never followed them), for instance in his famous demand that one be always opaque to the patient, and/or rigid adherence to one or another psychoanalytic theory, must be understood as a form of countertransference, a character flaw in the analyst.

    As stated in the NAS STR Report, "regional and large-scale reconstructions of changes in other climatic variables, such as precipitation, over the last 2,000 years would provide a valuable complement to those made for temperature." In this context, we focus on the 'Medieval Mega-drought Hypothesis', which is based on radiocarbon dating of dead trees and stumps found underwater in Sierra Nevada lakes and streambeds, and states that century-long dry periods caused lakes to retreat and streams to dry up, with the most recent mega-droughts happening during medieval times. While several paleoclimatic records support this hypothesis, some do not, and the possibility exists that geomorphic processes, such as landslides caused by seismic events, were responsible for the presence of trees and stumps under current bodies of water. Given the relevance of this hypothesis, not only for sustainable water management but also for social stability and security, it is necessary to test it beyond reasonable doubt. One way to do so is by measuring the location, orientation, and time of origin of underwater trees, to determine if they were transported or grew in situ. For example, during 2005 wood samples were retrieved from submerged trees at Fallen Leaf Lake, California. The trees had been previously located and documented using an ROV that can obtain high resolution color video, and collect small surface samples using a gripper, down to a water depth of about 150 m. For tree-ring dating, a reference chronology from AD 543 to 2003 was developed using live and dead western juniper trees located near the lake. One underwater sample, i.e. a branch cross section that included 69 rings, was then dated to AD 1085-1153. This shows that it is feasible to obtain calendar dates and continuous ring-width series from underwater trees in the Sierra Nevada. Submerged trees in Fallen Leaf Lake were mapped in summer 2006 using an EdgeTech 4200 side-scan system capable of decimeter resolution. The 5

    We attempted to confirm the resemblance of a local medieval population and to reconstruct their contribution to the formation of the modern Polish population at the DNA level. The HVR I mtDNA sequence and two nuclear alleles, LCT-13910C/T SNP and deltaF508 CFTR, were chosen as markers since the distribution of selected nuclear alleles varies among ethnic groups. A total of 47 specimens were selected from a medieval cemetery in Cedynia (located in the western Polish lowland). Regarding the HVR I profile, the analyzed population differed from the present-day population (P = 0.045, F(st) = 0.0103), in contrast to lactase persistence (LP) based on the LCT-13910T allele, thus indicating the lack of notable frequency changes of this allele during the last millennium (P = 0.141).

    We attempted to confirm the resemblance of a local medieval population and to reconstruct their contribution to the formation of the modern Polish population at the DNA level. The HVR I mtDNA sequence and two nuclear alleles, LCT-13910C/T SNP and deltaF508 CFTR, were chosen as markers since the distribution of selected nuclear alleles varies among ethnic groups. A total of 47 specimens were selected from a medieval cemetery in Cedynia (located in the western Polish lowland). Regarding the HVR I profile, the analyzed population differed from the present-day population (P = 0.045, F(st) = 0.0103), in contrast to lactase persistence (LP) based on the LCT-13910T allele, thus indicating the lack of notable frequency changes of this allele during the last millennium (P = 0.141). The sequence of the HVR I mtDNA fragment allowed to identify six major haplogroups including H, U5, T, K, and HV0 within the medieval population of Cedynia which are common in today's central Europe.

    The carbon dioxide contributing to binder formation during the set of a lime mortar reflects the atmospheric 14C content at the time of construction of a building. For this reason, the 14C dating of mortars is used with increasing frequencies in archaeological and architectural research. Mortars, however, may also contain carbonaceous contaminants potentially affecting radiocarbon dating. The Centre for Isotopic Research on Cultural and Environmental heritage (CIRCE) of the Second University of Naples (SUN) has recently obtained some promising results in mortar radiocarbon dating thanks to the development of a procedure (i.e. CryoSoniC/Cryo2SoniC) aiming to eliminate exogenous C contamination that may occur in a mortar. The construction history of the UNESCO World Heritage Site of Modena (Italy) is still controversial and represents a challenging case study for the application of absolute dating methodologies for different reasons. From the point of view of 14C dating, for example, given the high percentage of carbonate aggregates composing these samples, Modena mortars represent an experimental test particularly indicative of exogenous carbon sources suppression ensuring methodology accuracy. In this paper several AMS Radiocarbon dates were carried out on lime lumps with the aim to: (i) verify procedure accuracy by a comparison of the results obtainable from lime lumps dated after different treatments (i.e. bulk lime lumps vs. CryoSoniC purified lime lumps); (ii) compare different building phases absolute chronology for the medieval UNESCO site of Modena, with that assumed by historical sources in order to assess preliminary the 14C dating feasibility for of the site. Historical temporal constraints and mortar clustering, based on petrography, have been applied to define a temporal framework of the analyzed structure. Moreover, a detailed petrographic characterization of mortars was used both as a preliminary tool for the choice of samples and to infer about the

    Many of the largest wildfires in US history burned in recent decades, and climate change explains much of the increase in area burned. The frequency of extreme wildfire weather will increase with continued warming, but many uncertainties still exist about future fire regimes, including how the risk of large fires will persist as vegetation changes. Past fire-climate relationships provide an opportunity to constrain the related uncertainties, and reveal widespread burning across large regions of western North America during past warm intervals. Whether such episodes also burned large portions of individual landscapes has been difficult to determine, however, because uncertainties with the ages of past fires and limited spatial resolution often prohibit specific estimates of past area burned. Accounting for these challenges in a subalpine landscape in Colorado, we estimated century-scale fire synchroneity across 12 lake-sediment charcoal records spanning the past 2,000 y. The percentage of sites burned only deviated from the historic range of variability during the Medieval Climate Anomaly (MCA) between 1,200 and 850 y B.P., when temperatures were similar to recent decades. Between 1,130 and 1,030 y B.P., 83% (median estimate) of our sites burned when temperatures increased ∼0.5 °C relative to the preceding centuries. Lake-based fire rotation during the MCA decreased to an estimated 120 y, representing a 260% higher rate of burning than during the period of dendroecological sampling (360 to -60 y B.P.). Increased burning, however, did not persist throughout the MCA. Burning declined abruptly before temperatures cooled, indicating possible fuel limitations to continued burning. PMID:26438834

    The spatial-temporal distribution of late Holocene temperature changes over the last 2000 yr is still being defined. The high Arctic is often represented by the borehole tem-perature records from GISP and Dye 3. These both show a distinct, but different magni-tude, Medieval warm interval from ~500 to ~1200 AD, with two cold intervals after 1500 AD. However small glaciers in the high Arctic appear reflect a more complex late Holo-cene pattern. On the eastern coast of Greenland two ice caps record a warm interval from 400 AD to 600 AD but cooling after that. These ice caps, Istorvet ,on the coast beside the cold East Greenland Current, and Bregne ice cap, ~ 100 km inland, have yielded organic remains from > 50 sites. A preliminary interpretation is that the organic remains record the last time these ice caps were as small or smaller than the present configuration. Exposure ages show these ice caps reached their post glacial maximum extent within the last 1000 yr. The Istorvet ice cap is thought to show initial cooling at ~AD 884 and an advance to within 500 m of the Little Ice Age extent at AD 1022 and its fullest extent at 1125 AD. Core sediments suggest that extent was maintained until 1750 AD. Results from the inland site indicate a retracted ice cap from AD 1054 to 1393, followed by expansion. Although some of these events appear to have correlative events recorded in SST or sea ice near Iceland. Taken together they appear to have a different signature than lo-cations further south. This may indicate that temperature patterns at high latitudes are only partly coupled with those at lower latitudes.

    To better characterize the climate variability of the last millennium in the high Andes, we analysed the pollen content of a 1100-yr-old sediment core collected in a bog located at 3800 m a.s.l. in the páramo in the Eastern Cordillera in Ecuador. An upslope convective index based on the ratio between cloud transported pollen from the andean forest to the bog (T) and Poaceae pollen frequencies, related to the edaphic moisture of the páramo (P), was defined to distinguish the atmospheric moisture from the soil moisture content of the páramo. Results showed that between 900 AD and 1230 AD, the Medieval Climate Anomaly interval was warm and moist with high T/P index linked to a high ENSO variability and a weak South American Summer Monsoon (SASM) activity. Between 1230 and 1650 AD, a dry climate prevailed characterized by an abrupt decrease in the T/P index related to lower ENSO variability with significant impact on the floristic composition of the páramo. During the Little Ice Age, two phases were observed, first a wet phase between 1650 and 1750 AD linked to low ENSO variability in the Pacific and warm south equatorial Atlantic SSTs favored the return of a wet páramo, and a cold and dry phase between 1750 and 1810 AD associated with low ENSO variability and weak SASM activity resulting in drying of the páramo. The Current Warm Period marks the beginning of a climate characterized by high convective activity, the highest in the last millennium, and weaker SASM activity modifying the water stock of the páramo. Our results show that the páramo is progressively loosing its capacity for water storage and that the variability of both tropical Pacific and Atlantic SSTs matters for Andean climate patterns although many teleconnection mechanisms are still poorly understood.

  16. Medieval Warm Interval documented as drought in the northeastern US -implications for our future?

    The Northeastern United States comprise 5% of the total area of the US yet contain nearly 18% of the US population, including the densely settled metropolitan areas of New York, Philadelphia, and Boston. As such, the demands on the region's water resources are severe. Historical records include only one major drought in the last half-century, which occurred in the 1960s - it was considered severe but only lasted a few years. However, recent reconstructions from tree rings, pollen, and charcoal, extend the record and reveal the occurrence of numerous droughts over the last millennium, the severity and duration of which have not been experienced by modern society. For example, a "Megadrought" has been documented during the Medieval Warming Interval (MWI) from analysis of core samples collected in Piermont Marsh, NY, which makes even the recent droughts of the western US seem minor by comparison. Charcoal data from other NY marshes (Iona Marsh, 41 N, 74 W; Tivoli Bay, 43 N, 55 W) suggest that this drought was a regional phenomenon. Similar evidence of a MWI drought in peatlands as far north as the Great Heath, Maine (44 N, 67 W) indicates the entire Northeast suffered water shortages. Examination of drought records from upland lakes nearby indicate the MWI was only one of a series of droughts throughout the Holocene that the region has experienced. Comparison with coastal tree ring records various other records suggests that conditions may have extended as far south as Roanoke, Virginia. A similar extreme drought today would devastate those living in the Northeastern US who have been lulled into complacency by the current pluvial. Severe, prolonged droughts are the most expensive natural disasters affecting our planet, with damage in the US alone reaching US$6-8 billion annually. By coupling information from paleoarchives, current climate forcing mechanisms, and climate models, we will explore the mechanisms of megadroughts during the Holocene and the implications for

    Frankincense, the oleogum resin from Boswellia sp., has been an early luxury good in both Western and Eastern societies and is particularly used in Christian funerary and liturgical rites. The scant grave goods in late medieval burials comprise laterally perforated pottery vessels which are usually filled with charcoal. They occur in most regions of western Europe and are interpreted as incense burners but have never been investigated with advanced analytical techniques. We herein present chemical and anthracological results on perforated funerary pots from 4 Wallonian sites dating to the 12-14th century AD. Chromatographic and mass spectrometric analysis of lipid extracts of the ancient residues and comparison with extracts from four Boswellia species clearly evidence the presence of degraded frankincense in the former, based on characteristic triterpenoids, viz. boswellic and tirucallic acids, and their myriad dehydrated and oxygenated derivatives. Cembrane-type diterpenoids indicate B. sacra (southern Arabia) and B. serrata (India) as possible botanical origins. Furthermore, traces of juniper and possibly pine tar demonstrate that small amounts of locally available fragrances were mixed with frankincense, most likely to reduce its cost. Additionally, markers of ruminant fats in one sample from a domestic context indicate that this vessel was used for food preparation. Anthracological analysis demonstrates that the charcoal was used as fuel only and that no fragrant wood species were burned. The chars derived from local woody plants and were most likely recovered from domestic fires. Furthermore, vessel recycling is indicated by both contextual and biomarker evidence. The results shed a new light on funerary practices in the Middle Ages and at the same time reveal useful insights into the chemistry of burned frankincense. The discovery of novel biomarkers, namely Δ2-boswellic acids and a series of polyunsaturated and aromatic hydrocarbons, demonstrates the high

    Background and Aims Beginning in the last two decades of the 14th century, richly illuminated versions of the Tacuinum Sanitatis, the Latin translation of an 11th-century Arabic manuscript known as Taqwim al-Sihha bi al-Ashab al-Sitta, were produced in northern Italy. These illustrated manuscripts provide a window on late medieval life in that region by containing some 200 full-page illustrations, many of which vividly depict the harvest of vegetables, fruits, flowers, grains, aromatics and medicinal plants. Our objective was to search for and identify the images of taxa of Cucurbitaceae and Solanaceae. Methods We have located all reported illustrated Tacuinum Sanitatis and similar or related manuscripts, searched through printed or electronic reproductions of them, categorized six of them that display full-page illustrations as archetypic, and established the identity of the Cucurbitaceae and Solanaceae appearing in these six manuscripts. Key Results and Conclusions Of the Cucurbitaceae, Cucumis sativus (short-fruited cucumbers), Cucumis melo (including round as well as elongate melons), Citrullus lanatus (both sweet watermelons and citrons), and Lagenaria siceraria (including bottle-shaped as well as long gourds), are illustrated. Of the Solanaceae, Solanum melongena (egg-shaped purple aubergines) and Mandragora sp. (mandrake) are illustrated. These depictions include some of the earliest known images of cucumber, casaba melon (Cucumis melo Inodorous Group) and aubergine, each of which closely resembles an extant cultivar-group or market type. Overall, the botanically most accurate images are in the version of the Tacuinum located in the Österreichische Nationalbibliothek, Vienna, cod. ser. n. 2644. Similarities and differences in botanical accuracy among the images of Cucurbitaceae and Solanaceae in the six archetypal Tacuinum manuscripts suggest to us that another illustrated Tacuinum, now lost, may have antedated and served as a model or inspiration for the

    Apotropaic observances-traditional practices intended to prevent evil-were not uncommon in post-medieval Poland, and included specific treatment of the dead for those considered at risk for becoming vampires. Excavations at the Drawsko 1 cemetery (17th-18th c. AD) have revealed multiple examples (n = 6) of such deviant burials amidst hundreds of normative interments. While historic records describe the many potential reasons why some were more susceptible to vampirism than others, no study has attempted to discern differences in social identity between individuals within standard and deviant burials using biogeochemical analyses of human skeletal remains. The hypothesis that the individuals selected for apotropaic burial rites were non-local immigrants whose geographic origins differed from the local community was tested using radiogenic strontium isotope ratios from archaeological dental enamel. 87Sr/86Sr ratios ( = 0.7112±0.0006, 1σ) from the permanent molars of 60 individuals reflect a predominantly local population, with all individuals interred as potential vampires exhibiting local strontium isotope ratios. These data indicate that those targeted for apotropaic practices were not migrants to the region, but instead, represented local individuals whose social identity or manner of death marked them with suspicion in some other way. Cholera epidemics that swept across much of Eastern Europe during the 17th century may provide one alternate explanation as to the reason behind these apotropaic mortuary customs, as the first person to die from an infectious disease outbreak was presumed more likely to return from the dead as a vampire.

    Many of the largest wildfires in US history burned in recent decades, and climate change explains much of the increase in area burned. The frequency of extreme wildfire weather will increase with continued warming, but many uncertainties still exist about future fire regimes, including how the risk of large fires will persist as vegetation changes. Past fire-climate relationships provide an opportunity to constrain the related uncertainties, and reveal widespread burning across large regions of western North America during past warm intervals. Whether such episodes also burned large portions of individual landscapes has been difficult to determine, however, because uncertainties with the ages of past fires and limited spatial resolution often prohibit specific estimates of past area burned. Accounting for these challenges in a subalpine landscape in Colorado, we estimated century-scale fire synchroneity across 12 lake-sediment charcoal records spanning the past 2,000 y. The percentage of sites burned only deviated from the historic range of variability during the Medieval Climate Anomaly (MCA) between 1,200 and 850 y B.P., when temperatures were similar to recent decades. Between 1,130 and 1,030 y B.P., 83% (median estimate) of our sites burned when temperatures increased ∼0.5 °C relative to the preceding centuries. Lake-based fire rotation during the MCA decreased to an estimated 120 y, representing a 260% higher rate of burning than during the period of dendroecological sampling (360 to −60 y B.P.). Increased burning, however, did not persist throughout the MCA. Burning declined abruptly before temperatures cooled, indicating possible fuel limitations to continued burning. PMID:26438834

    Published annual-to-decadal resolution stalagmite δ18O records since AD 900 from six caves (Dongge, Furong, Heshang, Buddha, Shihua and Wanxiang) in China were analyzed to detect temporal and spatial variability of the East Asian Summer Monsoon strength which strongly affects wet/dry conditions in eastern China. The empirical mode decomposition method (Huang et al., 1998) was used to obtain trends of the six cave records. After the base trend was determined, δ18O anomalies of each record were computed by subtracting the base trend. Mean δ18O anomaly values of the detrended time series for each cave record were calculated for four periods: (1) medieval warm period (MWD, AD 900 - 1250), (2) little ice age phase-1 (LIA-1, AD 1250 -1550), (3) little ice age phase-2 (LIA-2, AD 1550 - 1850), and (4) modern period (MD-1, AD 1850 - 2000). From these anomalies, the temporal and spatial variability of wet/dry conditions has been identified. Positive values of the mean δ18O anomalies indicating drier conditions appeared in lower Yangtze River Drainage Area and Southeast Coast Area during MD-1, LIA-1 and MWD, whereas negative values existed in North, South and Yangtze areas of the eastern China. The results agree with Dryness/Wetness index reconstructed by Chinese historic records in general. These results illustrate that wet and dry conditions in different regions of the eastern China could be opposite under the monsoon influence, so that no single speleothem δ18O record could represent monsoonal climate in this vast region. The climatic patterns in the monsoonal region can either warm/wet (cold/dry) or cold/wet (warm/dry) on annual-to-centennial scales. A 128-yr periodic cycle exists in all six cave records, whereas 64-yr and 42-yr periodicities appear in the Shihua, Heshang and Dongge records. These cycles may reflect the influence of the solar activity on the East Asian Summer Monsoon.

    2014-01-01

    Background Habitat fragmentation has accelerated within the last century, but may have been ongoing over longer time scales. We analyzed the timing and genetic consequences of fragmentation in two isolated lake-dwelling brown trout populations. They are from the same river system (the Gudenå River, Denmark) and have been isolated from downstream anadromous trout by dams established ca. 600–800 years ago. For reference, we included ten other anadromous populations and two hatchery strains. Based on analysis of 44 microsatellite loci we investigated if the lake populations have been naturally genetically differentiated from anadromous trout for thousands of years, or have diverged recently due to the establishment of dams. Results Divergence time estimates were based on 1) Approximate Bayesian Computation and 2) a coalescent-based isolation-with-gene-flow model. Both methods suggested divergence times ca. 600–800 years bp, providing strong evidence for establishment of dams in the Medieval as the factor causing divergence. Bayesian cluster analysis showed influence of stocked trout in several reference populations, but not in the focal lake and anadromous populations. Estimates of effective population size using a linkage disequilibrium method ranged from 244 to > 1,000 in all but one anadromous population, but were lower (153 and 252) in the lake populations. Conclusions We show that genetic divergence of lake-dwelling trout in two Danish lakes reflects establishment of water mills and impassable dams ca. 600–800 years ago rather than a natural genetic population structure. Although effective population sizes of the two lake populations are not critically low they may ultimately limit response to selection and thereby future adaptation. Our results demonstrate that populations may have been affected by anthropogenic disturbance over longer time scales than normally assumed. PMID:24903056

    The study is focused on villages that are abandoned throughout the Basilicata from the 13th to the 15th century (Masini 1998), which is an emblematic case of abandonment of settlements in Late Middle Ages, which was a very common phenomenon throughout the whole Europe, attracting the interest of several historians and archaeologists (Demians d'Archimbaud 2001) The aim of the present study is to offer a contribution to knowledge of the medieval Basilicata's landscapes and settlement's dynamics with a multidisciplinary approach, derived from the rescue archeology: we have integrated the documentary sources with the use of spatial analysis and predictive models (Danese et al. 2009). The preventive archeology was born to conciliate the protection of archeological heritage, in evidence and potential, with the needs of urban design and planning. It is of fundamental importance, for a reliable evaluation of archaeological potential (identifying invisible traces) to use innovative diagnostic technologies: geophysical prospections, remote sensing (Lasaponara & Masini 2010; Lasaponara et al. 2016) and spatial analysis for the creation of predictive models. The latter are used to accomplish operational purposes but also for the historical landscape reconstruction (Danese et al. 2013; 2014). They contribute to analyse settlements and their dynamics on the basis of definite method and parameters. Thanks to predictive models it is possible, in fact, to start off by information of well-known archeological sites and use this knowledge as an empiric test for understand which elements have influenced their localization in the space. The relationships among natural environment, social context and position site are analysed in order to make clear the rules of settlement. These rules are then used into the model (Podobnikar et al. 2001). In this work the employed methodology is Spatial Analysis, in order to subdivide the territory based on its importance respect to a given function

  16. Alchemical poetry in medieval and early modern Europe: a preliminary survey and synthesis. Part I--Preliminary survey.

    Kahn, Didier

    2010-11-01

    This article provides a preliminary description of medieval and early modern alchemical poetry composed in Latin and in the principal vernacular languages of western Europe. It aims to distinguish the various genres in which this poetry flourished, and to identify the most representative aspects of each cultural epoch by considering the medieval and early modern periods in turn. Such a distinction (always somewhat artificial) between two broad historical periods may be justified by the appearance of new cultural phenomena that profoundly modified the character of early modern alchemical poetry: the ever-increasing importance of the prisca theologia, the alchemical interpretation of ancient mythology, and the rise of neo-Latin humanist poetry. Although early modern alchemy was marked by the appearance of new doctrines (notably the alchemical spiritus mundi and Paracelsianism), alchemical poetry was only superficially modified by criteria of a scientific nature, which therefore appear to be of lesser importance. This study falls into two parts. Part I provides a descriptive survey of extant poetry, and in Part II the results of the survey are analysed in order to highlight such distinctive features as the function of alchemical poetry, the influence of the book market on its evolution, its doctrinal content, and the question of whether any theory of alchemical poetry ever emerged. Part II is accompanied by an index of the authors and works cited in both parts. PMID:21465995

    Leprosy was rare in Europe during the Roman period, yet its prevalence increased dramatically in medieval times. We examined human remains, with paleopathological lesions indicative of leprosy, dated to the 6th-11th century AD, from Central and Eastern Europe and Byzantine Anatolia. Analysis of ancient DNA and bacterial cell wall lipid biomarkers revealed Mycobacterium leprae in skeletal remains from 6th-8th century Northern Italy, 7th-11th century Hungary, 8th-9th century Austria, the Slavic Greater Moravian Empire of the 9th-10th century and 8th-10th century Byzantine samples from Northern Anatolia. These data were analyzed alongside findings published by others. M. leprae is an obligate human pathogen that has undergone an evolutionary bottleneck followed by clonal expansion. Therefore M. leprae genotypes and sub-genotypes give information about the human populations they have infected and their migration. Although data are limited, genotyping demonstrates that historical M. leprae from Byzantine Anatolia, Eastern and Central Europe resembles modern strains in Asia Minor rather than the recently characterized historical strains from North West Europe. The westward migration of peoples from Central Asia in the first millennium may have introduced different M. leprae strains into medieval Europe and certainly would have facilitated the spread of any existing leprosy. The subsequent decline of M. leprae in Europe may be due to increased host resistance. However, molecular evidence of historical leprosy and tuberculosis co-infections suggests that death from tuberculosis in leprosy patients was also a factor.

    Atlantic cod (Gadus morhua) vertebrae from archaeological sites were used to study the history of the Icelandic Atlantic cod population in the time period of 1500-1990. Specifically, we used coalescence modelling to estimate population size and fluctuations from the sequence diversity at the cytochrome b (cytb) and Pantophysin I (PanI) loci. The models are consistent with an expanding population during the warm medieval period, large historical effective population size (NE), a marked bottleneck event at 1400-1500 and a decrease in NE in early modern times. The model results are corroborated by the reduction of haplotype and nucleotide variation over time and pairwise population distance as a significant portion of nucleotide variation partitioned across the 1550 time mark. The mean age of the historical fished stock is high in medieval times with a truncation in age in early modern times. The population size crash coincides with a period of known cooling in the North Atlantic, and we conclude that the collapse may be related to climate or climate-induced ecosystem change.

    Jung held an informal seminar for a limited number of students after the end of the Eranos Conference in August, 1943. All traces of this seminar were lost until the notes taken on it by one of the students, Alwine von Keller, were found in 2006. Jung's talk consisted of a psychological commentary on a series of images in the medieval Codex Palatinus Latinus 1993, attributed to Opicinus de Canistris (1296-c.1352), a fourteenth-century Italian clergyman, mystic, miniaturist, and cartographer. Jung interpreted Opicinus' images as a series of mandalas in which the Shadow, the dark principle, does not manage to be integrated into a balanced system. Opicinus tried to settle this division into opposites, which constitutes the main problem in modern times, while remaining inside the system of Christian doctrine. However, he did not succeed in his attempt to integrate the principle of the Shadow on the doctrinal level because he was not aware of the very same division in his own unconscious. Our article points out the features in the seminar where Jung seemed to show much more originality in his interpretation than other psychoanalytic studies on Opicinus or other analytical-psychological readings of medieval Christian art.

    Due to low durability, Northern European medieval glass undergoes the action of the atmospheric environment leading in some cases to a state of dramatic deterioration. Modification features varies from a simple loss of transparency to a severe material loss. In order to understand the underlying mechanisms and preserve this heritage, fundamental research is necessary too. In this optic, field exposure of analogues and original stained glass was carried out to study the early stages of the glass weathering. Model glass and original stained glass (after removal of deterioration products) were exposed in real conditions in an urban site (Paris) for 48 months. A regular withdrawal of samples allowed a follow-up of short-term glass evolution. Morphological modifications of the exposed samples were investigated through conventional and non destructive microscopy, using respectively a Scanning Electron Microscope (SEM) and an Interferometric Microscope (IM). This latter allows a 3D quantification of the object with no sample preparation. For all glasses, both surface recession and build-up of deposit were observed as a consequence of a leaching process (interdiffusion of protons and glass cations). The build-up of a deposit comes from the reaction between the extracted glass cations and atmospheric gases. Instead, surface recession is due mainly to the formation of brittle layer of altered glass at the sub-surface, where a fracture network can appear, leading to the scaling of parts of this modified glass. Finally, dissolution of the glass takes place, inducing the formation of pits and craters. The arithmetic roughness (Ra) was used as an indicator of weathering increase, in order to evaluate the deterioration state. For instance, the Ra grew from few tens of nm for pristine glass to thousands of nm for scaled areas. This technique also allowed a precise quantification of dimensions (height, depth and width) of deposits and pits, and the estimation of their overall

    Paleoclimate reconstructions of different global climate modes over the last 1000 years provide the basis for testing the relative roles of forced and unforced variability climate system, which can help us improve projections of future climate change. The Medieval Climate Anomaly (MCA) has been characterized by a combination of persistent La Niña-like conditions, a positive North Atlantic Oscillation (+NAO), and increased Atlantic Meridional Overturning Circulation (AMOC). The northern tropical Atlantic is sensitive to each of these climate patterns, but not all of them have the same regional fingerprint in the modern northern tropical Atlantic. The relative influence of different processes related to these climate patterns can help us better understand regional responses to climate change. The regional response of the northern tropical Atlantic is important because the tropical Atlantic Ocean is a large source of heat and moisture to the global climate system that can feedback onto global climate patterns. This study presents new coral Sr/Ca and δ18O data from the northern tropical Atlantic (Anegada, British Virgin Islands). Comparison of the sub-fossil corals that grew during the 13th and 14th Centuries with modern coral geochemical data from this site indicates relatively cooler mean conditions with a decrease in the oxygen isotopic composition of the water consistent with lower salinities. Similar average annual cycles between modern and sub-fossil Sr/Ca indicate no change in seasonal temperature range, but a difference in the relative phasing of the δ18O seasonal cycles indicates that the fresher mean conditions may be due to a more northerly position of the regional salinity front. This localized response is consistent with some, but not all of the expected regional responses to a La Niña-like state, a +NAO state, and increased AMOC. Understanding these differences can provide insight into the relative importance of advection versus surface fluxes for

  5. Dating Post-Medieval Archaeology: Which Global Geomagnetic Field Model to use?

    The scientific dating of Post-Medieval archaeology (16th Century onwards) is problematic as most methods cannot provide any better resolution than may be apparent from contextual or stylistic considerations. As high resolution global geomagnetic field models exist for this period, archaeomagnetism offers the possibility of bi-decadal dating of burnt in situ structures, with implications for the management of cultural heritage. The question arises as to which global geomagnetic field model is most appropriate for this dating? Should the high resolution historical field model, gufm (Jackson et al., 2000, Four centuries of geomagnetic secular variation from historical records, Phil. Trans. Roy. Soc. Lond. A, 358, 957- 90.) which covers the period 1590-1990 AD and is based on data from ship's logs be used, or should an archaeomagnetic model such as GMADE2K.2 (Lodge & Holme, 2008, Developing a global geomagnetic field model for archaeomagnetic dating in Europe for the last 2000 years (updating GMADE2K.1 to GMADE2K.2), Geophys. Res. Abstr., 10, Abstract EGU2008-A-03470) be used? In general a higher accuracy can be expected from the historical model, but the modeling strategy for gufm is aimed at investigating the magnetic field evolution at the core-mantle boundary, whilst GMADE2K.2 is developed to serve as an archaeomagnetic dating tool. If we compare secular variation curves in Europe for declination at this time, then the two models agree very well. For inclination however, there is a discrepancy pre-1800 AD between the two models, with the historical model tending to higher inclinations. Here we study the possible causes of this discrepancy: How reliable are the early historical inclination data? How reliable is the historical model at this time - is the inclination being affected by the domination of declination data? Finally, are the archaeomagnetic data systematically low, possibly caused by undetected magnetic refraction? The advantage of constructing global

    Osteoporosis has become a growing health concern in developed countries and an extensive area of research in skeletal biology. Despite numerous paleopathological studies of bone mass, few studies have measured bone quality in past populations. In order to examine age- and sex-related changes in one aspect of bone quality in the past, a study was made of trabecular bone architecture in a British medieval skeletal sample. X-ray images of 5-mm-thick coronal lumbar vertebral bone sections were taken from a total of 54 adult individuals divided into three age categories (18-29, 30-49, and 50+ years), and examined using image analysis to evaluate parameters related to trabecular bone structure and connectivity. Significant age-related changes in trabecular bone structure (trabecular bone volume (BV/TV), trabecular number (Tb.N), trabecular separation (Tb.Sp), and anisotropic ratio (Tb.An)) were observed to occur primarily by middle age with significant differences between the youngest and two older age groups. Neither sex showed continuing change in trabecular structure between the middle and old age groups. Age-related changes in bone connectivity (number of nodes (N.Nd) and node-to-node strut length (Nd.Nd)) similarly indicated a change in bone connectivity only between the youngest and two older age groups. However, females showed no statistical differences among the age groups in bone connectivity. These patterns of trabecular bone loss and fragility contrast with those generally found in modern populations that typically report continuing loss of bone structure and connectivity between middle and old age, and suggest greater loss in females. The patterns of bone loss in the archaeological samples must be interpreted cautiously. We speculate that while nutritional factors may have initiated some bone loss in both sexes, physical activity could have conserved bone architecture in old age in both sexes, and reproductive factors such as high parity and extended periods

    To better characterize the climate variability of the last millennium in the high Andes, we analyzed the pollen content of a 1150-yr-old sediment core collected in a bog located at 3800 m a.s.l. in the páramo in the eastern Cordillera in Ecuador. An upslope convective index based on the ratio between cloud transported pollen from the Andean forest to the bog (T) and Poaceae pollen frequencies, related to the edaphic moisture of the páramo (P), was defined. This index was used to distinguish changes in the atmospheric moisture from the soil moisture content of the páramo and their associated patterns of interdecadal El Niño-Southern Oscillation (ENSO) variability and South American summer monsoon (SASM) activity. Results show that between 850 and 1250 AD, the Medieval Climate Anomaly interval was warm and moist with a high transported pollen/Poaceae pollen (T/P) index linked to high ENSO variability and weak SASM activity. Between 1250 and 1550 AD, a dry climate prevailed, characterized by an abrupt decrease in the T/P index and therefore no upslope cloud convection, related to lower ENSO variability and with significant impact on the floristic composition of the páramo. During the Little Ice Age, two phases were observed: first, a wet phase between 1550 and 1750 AD linked to low ENSO variability in the Pacific and warm south equatorial Atlantic sea surface temperatures (SSTs) favored the return of a wet páramo, and then a cold and dry phase between 1750 and 1800 AD associated with low ENSO variability and weak SASM activity resulted in drying of the páramo. The current warm period marks the beginning of a climate characterized by high convective activity - the highest in the last millennium - and weaker SASM activity modifying the water storage of the páramo. Our results show that the páramo is progressively losing its capacity for water storage and that the interdecadal variability of both tropical Pacific and Atlantic SSTs matter for Andean climate

    Despite the immense impact that large, modern North American droughts, such as those of the 1930s and 1950s, have had on economic, social, aquacultural, and agricultural systems, they are smaller in duration and magnitude than the multidecadal megadroughts that affected North America, in particular the western United States, during the Medieval Climate Anomaly (MCA, ~ 900-1300 AD) and the Little Age (LIA, ~1450-1850 AD). Although various proxy records have been used to reconstruct the timing of these MCA and LIA megadroughts in the western United States, there still exists great uncertainty in the magnitude and spatial coherence of such droughts in the Pacific Northwest region, especially on decadal to centennial timescales. This uncertainty motivates the following study to establish a causal link between the climate forcing that induced these megadroughts and the spatiotemporal response of regional North American hydroclimates to this forcing. This study seeks to establish a better understanding of the influence of tropical Pacific and North Atlantic SSTs on North American drought during the MCA and LIA. We force NCAR's Community Atmospheric Model version 5.1.1 (CAM 5) with prescribed proxy-reconstructed tropical Pacific and North Atlantic SST anomalies from the MCA and LIA, in order to investigate the influence that these SST anomalies had on the spatiotemporal patterns of drought in North America. To isolate the effects of individual ocean basin SSTs on the North American climate system, the model experiments use a variety of SST permutations in the tropical Pacific and North Atlantic basin as external forcing. In order to quantify the spatiotemporal response of the North American climate system to these SST forcing permutations, temperature and precipitation data derived from the MCA and LIA model experiments are compared to lake sediment isotope and tree ring-based hydroclimate reconstructions from the Pacific Northwest.

    The Chapel of Pécsvárad is one of the best preserved and oldest medieval stone monument in South Hungary. It dates back to the 11th century. The interior of the chapel is decorated with wall paintings, which are later and probably originating from the late 12th century. The wall painting is partly preserved and it is located on an interior stone wall of the chapel facing to the East. The wall painting shows various forms of damage from salt efflorescence to chipping. The current research provides information on the in situ and laboratory analyses of salts, plasters, pigments and stone material suggesting mechanisms of decay that lead to partial loss of the painting. Both on site techniques and laboratory analyses were performed. Imaging techniques such as UV luminescence and IR thermography were used to identify the moist and salt covered zones on the wall surface. Portable moisture meter were also applied to map the wet zones in the interior and also at the external part of the chapel. Schmidt hammer and Duroscop were used for testing the surface strength of stone. Laboratory tests were focused on mineralogical and chemical compositional analyses. Small samples of stone, mortar, plaster and pigments were tested by optical microscopy, SEM-EDX, XRD and Thermogravimetric analyses. According to our tests the chapel was predominantly made of porous limestone and sandstone. Laboratory analyses proved that the major salt responsible for the damage of external walls are gypsum and halite, while in the interior part higher amount of halite and significant amount of sodium-nitrate were found besides gypsum. The painted layers are on Byzantine-type of plaster with organic compounds (plant fragments) and with a substrate layer rich in calcium carbonate. The identified pigments are dominantly earth pigments such as iron-oxide containing red and yellow (ochre) and green earth. A unique preservation of ultramarine blue in Hungary was found on the wall painting. The partial

    The end of the Roman period in many parts of north-western Europe coincided with severe population decline and collapsing trade routes. To what extent the long-distance transport routes changed from Roman to early-medieval periods and what their exact nature was, is generally unknown. Only few historical sources are available for this period, and archaeological records complex. Traditionally, research on the long-distance exchange of goods therefore generally has focussed on the spatial analyses of archaeologically recognizable goods (e.g. jewellery, religious artefacts). Although these endeavours greatly increase our understanding of long-distance trade networks, they probably in itself do not represent the full spectrum of common exchange networks and transport routes. By using a dendroarchaeological approach we were able to analyse long-distance transport routes of imported timber in the Roman and early-medieval Netherlands. By combining the provenance of exogenous timbers with data on modelled Roman and early-medieval route networks, we were able to reconstruct: (a) Roman and early-medieval trade networks in structural timbers, (b) changing transport routes in structural timbers and (c) model spatially shifting frequent-travel zones in the research area.

    High-resolution palaeoclimate reconstructions are essential to identify possible influences of climate variability on landscape evolution and landscape-related cultural changes (e.g., shifting settlement patterns and long-distance trade relations). North-western Europe is an ideal research area for comparison between climate variability and cultural transitions given its geomorphological diversity and the significant cultural changes that took place in this region during the last two millennia (e.g., the decline of the Roman Empire and the transition to medieval kingdoms). Compared to more global climate records, such as ice cores and marine sediments, terrestrial climate proxies have the advantage of representing a relatively short response time to regional climatic change. Furthermore for this region large quantity of climate reconstructions is available covering the last millennium, whereas for the first millennium AD only few high resolution climate reconstructions are available. We compiled climate reconstructions for sites in North-western Europe from the literature and its underlying data. All these reconstructions cover the time period of AD 1 to 1000. We only selected data with an annual to decadal resolution and a minimum resolution of 50 years. This resulted in 18 climate reconstructions from different archives such as chironomids (1), pollen (4), Sphagnum cellulose (1), stalagmites (6), testate amoebae (4), and tree-rings (2). The compilation of the different temperature reconstructions shows similar trends in most of the records. Colder conditions since AD 300 for a period of approximately 400 years and warmer conditions after AD 700 become apparent. A contradicting signal is found before AD 300 with warmer conditions indicated by most of the records but not all. This is likely the result of the use of different proxies, reflecting temperatures linked to different seasons. The compilation of the different precipitation reconstructions also show similar

  15. Eclipses in the Middle East from the Late Medieval Islamic Period to the Early Modern Period. Part 1: The observation of six lunar eclipses from the Late Medieval Islamic Period

    This paper deals with the analysis of data obtained from observations of two sets of three lunar eclipses in the Late Medieval Islamic Period. The first trio consists of the lunar eclipses of 7 March 1262, 7 April 1270 and 24 January 1274, observed by Muḥyī al-Dīn al-Maghribī; from the Maragha Observatory (in north-western Iran), and the second includes those of 2 June and 26 November 1406, and 22 May 1407, observed by Jamshīd Ghiyāth al-Dīn al-Kāshī from Kāshān (in central Iran). The results are that al-Maghribī's values for the magnitudes of these eclipses agree excellently with modern data, and his values for the times when the maximum phases occurred agree to within five minutes with modern values. Al-Kāshī's values for the times of the maximum phases show a rather larger divergence from modern data, varying from about ten minutes to about one hour. The errors in all six values both astronomers computed from their own solar parameters for the longitude of the Sun at the instant of the opposition of the Moon to the Sun in these eclipses remain below ten minutes of arc. The motivation for doing these observations was to measure the lunar epicycle radius r in the Ptolemaic model. Al-Maghribī achieved r = 5;12 and al-Kāshī r ∼ 5;17,1 in terms of the radius of an orbit of R = 60 arbitrary units. It is argued that comparing with modern theory, neither of these two medieval values can be considered an improvement on Ptolemy's value of r = 5;15.

    In this contribution, the results of some integrated geophysical prospecting (magnetometric and GPR) are exposed. This work has been performed in collaboration between archaeologists and geophysicists within the research project "History and Global Archaeology of the Rural Landascapes in Italy, between Late Antiquity and Medieval period. Integrated systems of sources, methodologies, and technologies for a sustainable development", financed by the Italian Ministry for Instruction, University and Research MIUR. In particular, the archaeological sites of Badia and San Giovanni in Malcantone, both in the Apulia Region (eastern-southern Italy) have been prospect. The sites have been identified on the basis of available documents, archaeological surveys and testimonies. In particular, we know that in Badia [1] it was probable the presence of an ancient roman villa of the late ancient period (strongly damaged by the subsequent ploughing activities). Whereas in San Giovanni there is still, today, a small chapel (deconsecrated) that was likely to be part of a previous larger church (probably a basilica of the early Christian period) restricted in the subsequent centuries (probably in more phases). The Saracen raids of the XVI centuries made the site ruined and abandoned. In both sites integrated prospecting have been performed [2-6] with a the integration of archaeological, magnetometer and a GPR data have provided some interesting results, allowing to overcome the difficulties relative to an extensive GPR prospecting, that could not be performed because of the intrinsic superficial roughness and/or the intensive ploughing activities. The prospecting activities, in particular, have added elements that seem to confirm the main archaeological hypothesis that motivate their performing, as it will be show at the conference.

    2013-06-01

    The article seeks out the regulations about public health in the oldest medieval statutes of fourteen cities of the eastern Croatian Adriatic coast, between the thirteenth and sixteenth century. The research revealed numerous examples of direct or indirect ways of protecting public health. Through the analyzed documents, a noteworthy relationship between public morality and public health can be noted. The described rules are important as a reflection of awareness about public health as a condition of survival and progress in the past. They witness a progressive transition from an original common law into a written law as well as the impact that religion had in influencing people's general opinion and lifestyle in light of public health problems.

  19. Late Holocene flood probabilities in the Black Hills, South Dakota with emphasis on the Medieval Climate Anomaly

    2015-01-01

    A stratigraphic record of 35 large paleofloods and four large historical floods during the last 2000 years for four basins in the Black Hills of South Dakota reveals three long-term flooding episodes, identified using probability distributions, at A.D.: 120–395, 900–1290, and 1410 to present. During the Medieval Climate Anomaly (~ A.D. 900–1300) the four basins collectively experienced 13 large floods compared to nine large floods in the previous 800 years, including the largest floods of the last 2000 years for two of the four basins. This high concentration of extreme floods is likely caused by one or more of the following: 1) instability of air masses caused by stronger than normal westerlies; 2) larger or more frequent hurricanes in the Gulf of Mexico and Atlantic Ocean; and/or 3) reduced land covering vegetation or increased forest fires caused by persistent regional drought.

    The Pope John XXI, named Pedro Rebuli Guiliani, was born in Lisbon, Portugal, around 1215. Known as Petrus Hispanus, Master Jullian, Peter of Spain, among other names. Besides medical studies, he studied Theology , Aristotelic Physics and Metaphysics at the University of Paris. He was named Professor of Medicine and Ophthalmology at the University of Sienna in 1247. In addition to several works about medicine, logic, and phylosophy, he authored the Tesaurus Pauperum ("Treasure of the Poor"), a prescription handbook of home-made, simple and cheap remedies. He was archbishop of Braga and Cardinal in 1272 and 1273, respectively. Elected Pope in 1276, he died tragically on May 20, 1277.

  1. The stars and the state: Astronomy, astrology, and the politics of natural knowledge in early medieval Japan

    NASA Astrophysics Data System (ADS)

    Buhrman, Kristina Mairi

    This dissertation examines the social factors involved in the practices of observational astrology (Ch. tianwen, Jp. tenmon ) and calendrical astronomy (Ch. lifa, Jp. rekihō) at the Japanese court. The production and monopolization of astrological and astronomical knowledge had, from the time of the Han Dynasty in China, been part of the state bureaucracy and one of the signs of legitimate rule. In the seventh century, Japan too had imported and implemented these state sciences of the Chinese-style imperium. However, by the twelfth century, while state control of astronomical knowledge continued to operate at a surface level, within the Japanese court bureaucracy dissent and debate reigned. A number of lineages and factions cooperated or competed over astronomical and astrological facts, which resulted in a situation where there was no unified "truth" about the stars accepted by the majority of elite members of the court. The political fragmentation and factionalism that characterized the early medieval Japanese state was also to be found in knowledge about the natural world circulating at court. The major reason for this fragmentation of knowledge was the diversity of the population that produced this same knowledge, a population that did not share either a common identity or definition of practice. Astrological and astronomical knowledge was no longer produced solely by the technical bureaucrats whose offices had been established in the eighth-century Chinese-style law codes (Jp. ritsuryō)—instead, these officials contested with other legitimate but non-official purveyors of natural knowledge: Buddhist monks and court scholars and mathematicians prominent among them. Furthermore, the statements of fact produced by all three of these factions were subject to critique and revision by members of the top echelon of the court bureaucracy, the elite nobility. Clearly there were no

    2010-01-01

    David Macht already stated that in several ancient languages the same term is used for kidneys and testes. "Preparation or elaboration of the semen was considered to be one of the functions of the kidneys in man". In the Bible, however, this confusion does not exist, at least not on the anatomical level. Together with the heart, the kidneys are paradigmatic of the innermost organs, wherefrom result their metaphoric association in being the seat of emotions and of wisdom. Some of these aspects will be delineated in the present study, briefly in Bible and Talmud, while stressing medieval Jewish sources, including the works of Shabtai Donnolo, Judah Halevi, Shem-Tov Falaquera, and Meir ibn Aldabi.

  3. Bim from Laser SCANS… not Just for Buildings: Nurbs-Based Parametric Modeling of a Medieval Bridge

    Building Information Modelling is not limited to buildings. BIM technology includes civil infrastructures such as roads, dams, bridges, communications networks, water and wastewater networks and tunnels. This paper describes a novel methodology for the generation of a detailed BIM of a complex medieval bridge. The use of laser scans and images coupled with the development of algorithms able to handle irregular shapes allowed the creation of advanced parametric objects, which were assembled to obtain an accurate BIM. The lack of existing object libraries required the development of specific families for the different structural elements of the bridge. Finally, some applications aimed at assessing the stability and safety of the bridge are illustrated and discussed. The BIM of the bridge can incorporate this information towards a new "BIMonitoring" concept to preserve the geometric complexity provided by point clouds, obtaining a detailed BIM with object relationships and attributes.

    The early medieval era is also called the Islamic Golden Age because of the significant rise in sciences, including medicine. Abū Bakr Rabi' ibn Ahmad Akhawayni Bukhāri (better known as Akhawayni) was one of the notable medical practitioners in his lifetime. His fame was in neuroscience and he became known as Pezeshk-e-Divanegan (Physician to the Insane). His only surviving book, Hidāyat al-Muta'allimin fi al-Tibb (The Students' Handbook of Medicine), is the first medical textbook in Persian, after Islam. Akhawayni gathered and categorized available knowledge on neuropsychiatry and added his own. He was the first to describe sleep paralysis and to suggest pragmatic rather than supernatural treatment. He was also the first to present fever cure and his descriptions of meningitis (Lisarghos in Hidāyat), mania, psychosis (Malikhulia), dementia (Ghotrab), etc., are close to current concepts.

  5. Stable isotope ratio analysis of breastfeeding and weaning practices of children from medieval Fishergate House York, UK.

    2013-11-01

    Rib collagen of 51 juveniles and 11 adult females from the late medieval Fishergate House cemetery site (York, UK) were analyzed using nitrogen and carbon stable isotope ratio analysis to determine the weaning age for this population and to reconstruct diet. The juveniles' ages ranged from fetal to 5-6 years, while the females were of reproductive age. Previous researchers suggested that the children from Fishergate House might have been weaned later than the medieval British norm of 2 years, based on a mortality peak at 4-6 years of age. The results show weaning was complete by 2 years of age, agreeing with previous British weaning studies. The adult female δ(15) N values have a mean of 11.4‰ ± 1.1‰ and the δ(13) C values have a mean of -19.4‰ ± 0.4‰. These findings are consistent with previous isotopic studies of female diet in York during this period, though slightly lower. The weaned juvenile nitrogen values were found to be higher than the adult females (12.4‰ ± 1.0‰ for δ(15) N and -19.7‰ ± 0.5‰ for δ(13) C), which might indicate a dependence on higher trophic level proteins such as marine fish or pork. Marine fish is considered a high status food and children are considered low-status individuals at this time, making this a particularly interesting finding. Weaning does not appear to coincide with peak mortality, suggesting environment factors may be playing a larger role in child mortality at Fishergate House.

  6. Frequency and patterning of bone trauma in the late medieval population (13th-16th century) from Dugopolje, southern Croatia.

    PubMed

    Novak, Mario; Slaus, Mario

    2012-07-01

    The aim of this paper is to test the hypothesis of an increased level of interpersonal violence in Dugopolje during the late medieval period as testified by written sources. In order to accomplish this, an analysis and comparison of frequencies and patterning of long bone and craniofacial fractures between sex and age categories in the Dugopolje skeletal sample was performed. In total 209 excellently preserved adult skeletons were analysed: 111 males and 98 females. The total long bone fracture frequency is 1.5% (29/1910) with a significantly higher frequency in males compared to females. Most of the long bone injuries occurred as a result of accidents, probably due to rugged mountainous terrain, while a certain portion of trauma resulted from deliberate violence. Significantly higher fracture frequencies in males could be a result of a strict sexual division of labour where males performed more physically demanding and risky tasks, as witnessed by historical sources. 26 out of 119 complete adult crania (21.8%) exhibit skeletal trauma with significantly higher frequencies in males. Perimortem trauma was observed in one individual while antemortem healed sharp force lesions were registered in five individuals (all males). The predominance of frontal craniofacial injuries, as well as the presence ofperimortem trauma and sharp force lesions, suggests the presence of deliberate violence in this community. Although the indicators of deliberate violence were recorded predominantly in males, suggesting that intentional violence in Dugopolje was exclusively males' prerogative, the presence of nasal fracture in a female skeleton might point to a male towards female violence. Presented bioarchaeological data are in accordance with the written documents thus corroborating the claims of an increased level of deliberate interpersonal violence in the late medieval population from Dugopolje.

  7. Socio-cultural factors in dental diseases in the Medieval and early Modern Age of northern Spain.

    2012-02-01

    The aim of this study is to present, discuss and compare the results of pathological conditions in teeth from skeletal remains found in the northern part of the Iberian Peninsula (Spain) in four Medieval cemeteries (late 15th century) and three cemeteries from the Modern Age (late 18th century). The final objective was to evaluate the impact of socioeconomic and cultural changes that took place during the early Modern Age in Spain, on oral health. Dental caries and antemortem tooth loss were considered as indicators of dental disease. A significant increase of both dental caries and antemortem tooth loss occurred in Modern Age individuals when compared to Medieval values, as reported for other regions. Increased trade with other continents may explain this deterioration of dental health, as food exchanges (mainly with America) contributed to diet changes for the overall population, including higher carbohydrate consumption (introduction of potatoes) at the expense of other vegetables. A sex-specific increase of dental disease with age, and a significantly higher prevalence of carious lesions in Modern Age females than in males, were also found. These changes can be explained by women having had limited access to dental care after the Middle-Modern Age transition, as a consequence of socio-cultural and political changes. In these changes, an increasing influence of the Catholic Church in Spanish society has to be noted, as it can contribute to the explanation of the unequal dental health of men and women. Women were socially excluded from dental care by regulations inspired by religious precepts.

  8. Medieval herbal iconography and lexicography of Cucumis (cucumber and melon, Cucurbitaceae) in the Occident, 1300–1458

    PubMed Central

    Paris, Harry S.; Janick, Jules; Daunay, Marie-Christine

    2011-01-01

    Background The genus Cucumis contains two species of important vegetable crops, C. sativus, cucumber, and C. melo, melon. Melon has iconographical and textual records from lands of the Mediterranean Basin dating back to antiquity, but cucumber does not. The goal of this study was to obtain an improved understanding of the history of these crops in the Occident. Medieval images purportedly of Cucumis were examined, their specific identity was determined and they were compared for originality, accuracy and the lexicography of their captions. Findings The manuscripts having accurate, informative images are derived from Italy and France and were produced between 1300 and 1458. All have an illustration of cucumber but not all contain an image of melon. The cucumber fruits are green, unevenly cylindrical with an approx. 2:1 length-to-width ratio. Most of the images show the cucumbers marked by sparsely distributed, large dark dots, but images from northern France show them as having densely distributed, small black dots. The different size, colour and distribution reflect the different surface wartiness and spininess of modern American and French pickling cucumbers. The melon fruits are green, oval to serpentine, closely resembling the chate and snake vegetable melons, but not sweet melons. In nearly all manuscripts of Italian provenance, the cucumber image is labelled with the Latin caption citruli, or similar, plural diminuitive of citrus (citron, Citrus medica). However, in manuscripts of French provenance, the cucumber image is labelled cucumeres, which is derived from the classical Latin epithet cucumis for snake melon. The absence of melon in some manuscripts and the expropriation of the Latin cucumis/cucumer indicate replacement of vegetable melons by cucumbers during the medieval period in Europe. One image, from British Library ms. Sloane 4016, has a caption that allows tracing of the word ‘gherkin’ back to languages of the geographical nativity of C

    The European Middle Ages inherited star names and constellations from Roman antiquity, mostly via Latin literary texts. When, from the 11th century onwards, Arabic texts and instruments became available, figures and vocabulary at first where not compatible with this tradition. The example of an excerpt from Pseudo-Hyginus De Astronomia shows, how a Roman text on the constellations was revised and supplemented with the names of the astrolabe-stars to combine the two different traditions.

  11. Impact of industrialization: comparative study of child health in four sites from medieval and postmedieval England (A.D. 850-1859).

    PubMed

    Lewis, Mary E

    2002-11-01

    The morbidity and mortality profiles of 831 non-adult skeletons from four contrasting sites in medieval and postmedieval England were compared to assess whether urbanization and later industrialization, had a detrimental effect on the health of the inhabitants. Failure in the population's ability to adapt to these environments should be evident in the higher rates of mortality, retarded growth, higher levels of stress, and a greater prevalence of metabolic and infectious disease in the urban groups. Non-adult skeletons were examined from Raunds Furnells in Northamptonshire, from St. Helen-on-the-Walls and Wharram Percy in Yorkshire, and from Christ Church Spitalfields in London. Results showed that a greater number of older children were being buried at the later medieval sites and that the skeletal growth profiles of the medieval urban and rural children did not differ significantly. A comparison of the growth profiles of St. Helen-on-the-Walls (urban) and Spitalfields (industrial) showed that the Spitalfields children were up to 3 cm shorter than their later medieval counterparts. At Spitalfields, cribra orbitalia and enamel hypoplasias occurred during the first 6 months of life, and 54% of the non-adults had evidence of metabolic disease. It is argued that differences in the morbidity and mortality of non-adults from urban and rural environments did exist in the past, but that it was industrialization that had the greatest impact on child health. Environmental conditions, urban employment, socioeconomic status, and changes in weaning ages and infant feeding practices contributed to differences in health in rural, urban, and industrial environments.

  13. Bone fractures as indicators of intentional violence in the eastern Adriatic from the antique to the late medieval period (2nd-16th century AD).

    2012-09-01

    To test the historically documented hypothesis of a general increase in deliberate violence in the eastern Adriatic from the antique (AN; 2nd-6th c.) through the early medieval (EM; 7th-11th c.) to the late-medieval period (LM; 12th-16th c.), an analysis of the frequency and patterning of bone trauma was conducted in three skeletal series from these time periods. A total of 1,125 adult skeletons-346 from the AN, 313 from the EM, and 466 from the LM series-were analyzed. To differentiate between intentional violence and accidental injuries, data for trauma frequencies were collected for the complete skeleton, individual long bones, and the craniofacial region as well as by type of injury (perimortem vs. antemortem). The results of our analyses show a significant temporal increase in total fracture frequencies when calculated by skeleton as well as of individuals exhibiting one skeletal indicator of deliberate violence (sharp force lesions, craniofacial injuries, "parry" fractures, or perimortem trauma). No significant temporal increases were, however, noted in the frequencies of craniofacial trauma, "parry" fractures, perimortem injuries, or of individuals exhibiting multiple skeletal indicators of intentional violence. Cumulatively, these data suggest that the temporal increase in total fracture frequencies recorded in the eastern Adriatic was caused by a combination of factors that included not only an increase of intentional violence but also a significant change in lifestyle that accompanied the transition from a relatively affluent AN urban lifestyle to a more primitive rural medieval way of life.

  14. Evidence for the Continued Use of Medieval Medical Prescriptions in the Sixteenth Century: A Fifteenth-Century Remedy Book and its Later Owner.

    PubMed

    Connolly, Margaret

    2016-04-01

    This article examines a fifteenth-century remedy book, Oxford, Bodleian Library, Rawlinson c. 299, and describes its collection of 314 medieval medical prescriptions. The recipes are organised broadly from head to toe, and often several remedies are offered for the same complaint. Some individual recipes are transcribed with modern English translations. The few non-recipe texts are also noted. The difference between a remedy book and a leechbook is explained, and this manuscript is situated in relation to other known examples of late medieval medical anthologies. The particular feature that distinguishes Oxford, Bodleian Library, Rawlinson c. 299 from other similar volumes is the evidence that it continued to be used during the sixteenth century. This usage was of two kinds. Firstly, the London lawyer who owned it not only inscribed his name but annotated the original recipe collection in various ways, providing finding-aids that made it much more user-friendly. Secondly, he, and other members of his family, added another forty-three recipes to the original collection (some examples of these are also transcribed). These two layers of engagement with the manuscript are interrogated in detail in order to reveal what ailments may have troubled this family most, and to judge how much faith they placed in the old remedies contained in this old book. It is argued that the knowledge preserved in medieval books enjoyed a longevity that extended beyond the period of the manuscript book, and that manuscripts were read and valued long after the advent of printing.

  15. The stars and the state: Astronomy, astrology, and the politics of natural knowledge in early medieval Japan

    NASA Astrophysics Data System (ADS)

    Buhrman, Kristina Mairi

    This dissertation examines the social factors involved in the practices of observational astrology (Ch. tianwen, Jp. tenmon ) and calendrical astronomy (Ch. lifa, Jp. rekihō) at the Japanese court. The production and monopolization of astrological and astronomical knowledge had, from the time of the Han Dynasty in China, been part of the state bureaucracy and one of the signs of legitimate rule. In the seventh century, Japan too had imported and implemented these state sciences of the Chinese-style imperium. However, by the twelfth century, while state control of astronomical knowledge continued to operate at a surface level, within the Japanese court bureaucracy dissent and debate reigned. A number of lineages and factions cooperated or competed over astronomical and astrological facts, which resulted in a situation where there was no unified "truth" about the stars accepted by the majority of elite members of the court. The political fragmentation and factionalism that characterized the early medieval Japanese state was also to be found in knowledge about the natural world circulating at court. The major reason for this fragmentation of knowledge was the diversity of the population that produced this same knowledge, a population that did not share either a common identity or definition of practice. Astrological and astronomical knowledge was no longer produced solely by the technical bureaucrats whose offices had been established in the eighth-century Chinese-style law codes (Jp. ritsuryō)—instead, these officials contested with other legitimate but non-official purveyors of natural knowledge: Buddhist monks and court scholars and mathematicians prominent among them. Furthermore, the statements of fact produced by all three of these factions were subject to critique and revision by members of the top echelon of the court bureaucracy, the elite nobility. Clearly there were no

    Tropical sea surface temperature (SST) has been implicated as a driver of climate changes during the Medieval Climate Anomaly (MCA, 950-1300 A.D.) but little data exists from the tropical oceans during this time period. We collected three modern and seven sub-fossil Diploria strigosa coral colonies from an overwash deposit on Anegada, British Virgin Islands (18.73 °N, 63.33 °W) in order to reconstruct climate in the northeastern Caribbean and Tropical North Atlantic during the MCA. The first step in our reconstruction was to verify the climate signal from this species at this site. We sub-sampled the modern corals along thecal walls with an average sampling resolution of 11-13 samples per year. Sr/Ca ratios measured in the sub-samples were calibrated to temperature using three different calibration techniques (ordinary least squares, reduced major axis, and weighted least squares (WLS)) on the monthly data that includes the seasonal cycles and on the monthly anomaly data. WLS regression accounts for unequal errors in the x and y terms, so we consider it the most robust technique. The WLS regression slope between gridded SST and coral Sr/Ca is similar to the previous two calibrations of this species. Mean Sr/Ca for each of the three modern corals is 8.993 × 0.004 mmol/mol, 9.127 × 0.003 mmol/mol, and 8.960 × 0.007 mmol/mol. These straddle the mean Diploria strigosa Sr/Ca found by Giry et al., (2010), 9.080 mmol/mol, at a site with nearly the same mean SST as Anegada (27.4 °C vs. 27.5 °C). The climatological seasonal cycles for SST derived from the modern corals are statistically indistinguishable from the seasonal cycles in the instrumental SST data. The coral-based seasonal cycles have ranges of 2.70 × 0.31 °C, 2.65 × 0.08 °C and 2.71 × 0.53 °C. These results indicate that this calibration can be applied to our sub-fossil coral data. We applied the WLS calibration to monthly-resolution Sr/Ca data from multiple sub-fossil corals dating to the medieval

  17. Did medieval trade activity and a viral etiology control the spatial extent and seasonal distribution of Black Death mortality?

    PubMed

    Bossak, Brian H; Welford, Mark R

    2009-06-01

    Recent research into the world's greatest recorded epidemic, the Medieval Black Death (MBD), has cast doubt on Bubonic Plague as the etiologic agent. Prior research has recently culminated in outstanding advances in our understanding of the spatio-temporal pattern of MBD mortality, and a characterization of the incubation, latent, infectious, and symptomatic periods of the MBD. However, until now, several mysteries remained unexplained, including perhaps the biggest quandary of all: why did the MBD exhibit inverse seasonal peaks in mortality from diseases recorded in modern times, such as seasonal Influenza or the Indian Plague Epidemics of the early 1900 s? Although some have argued that climate changes likely explain the observed differences between modern clinical Bubonic Plague seasonality and MBD mortality accounts, we believe that another factor explains these dissimilarities. Here, we provide a synthetic hypothesis which builds upon previous theories developed in the last ten years or so. Our all-encompassing theory explains the causation, dissemination, and lethality of the MBD. We theorize that the MBD was a human-to-human transmitted virus, originating in East-Central Asia and not Africa (as some recent work has proposed), and that its areal extent during the first great epidemic wave of 1347-1350 was controlled hierarchically by proximity to trade routes. We also propose that the seasonality of medieval trade controlled the warm-weather mortality peaks witnessed during 1347-1350; during the time of greatest market activity, traders, fairgoers, and religious pilgrims served as unintentional vectors of a lethal virus with an incubation period of approximately 32 days, including a largely asymptomatic yet infectious period of roughly three weeks. We include a description of the rigorous research agenda that we have proposed in order to subject our theory to scientific scrutiny and a description of our plans to generate the first publicly available

  18. Leadership in literature.

    2006-03-01

    Business students nowadays are not, for the most part, poets. A growing proportion come to business school with a background in investment banking or management consulting and an undergraduate business major, rather than a degree in the arts and sciences. MBA students are already very familiar with business. A number of scholars and businesspeople have begun to question the scientific model that dominates business research and teaching. Formalized management tools work well enough if you're studying techniques for financial valuation, but less so when you're studying leadership and organizational behavior. Some argue that students could learn a lot more about these subjects if they took a course in literature. Examples from fiction can be as instructive as any business textbook. HBR senior editor Diane Coutu recently met with Joseph Badaracco, Jr., for a wide-ranging discussion of what leaders can learn from literature. For the past decade, Badaracco, the John Shad Professor of Business Ethics at Harvard Business School, has used classical literature to provide well-rounded, complex pictures of leaders in all walks of life-particularly leaders whose psychological and emotional challenges parallel those of senior executives. Fiction provides some of the most powerful and engaging case studies ever written. Unlike contemporary management literature, which is relentlessly upbeat, classical literature is unsparingly realist. Leaders often struggle and sometimes fail-and the stakes are high. When business leaders read about the conflicts of literary characters, they can better understand their own circumstances. We pay far too little attention to the inner lives of leaders. Business school courses seem to suggest that you can treat executives like lab animals and control their behavior through their environment. But behaviorism is not enough. Literature suggests that leaders should learn more about themselves if they want to succeed.

  12. The improbable but unexceptional occurrence of megadrought clustering in the American West during the Medieval Climate Anomaly

    NASA Astrophysics Data System (ADS)

    Coats, Sloan; Smerdon, Jason E.; Karnauskas, Kristopher B.; Seager, Richard

    2016-07-01

    The five most severe and persistent droughts in the American West (AW) during the Common Era occurred during a 450 year period known as the Medieval Climate Anomaly (MCA—850-1299 C.E.). Herein we use timeseries modeling to estimate the probability of such a period of hydroclimate change occurring. Clustering of severe and persistent drought during an MCA-length period occurs in approximately 10% of surrogate timeseries that were constructed to have the same characteristics as a tree-ring derived estimate of AW hydroclimate variability between 850 and 2005 C.E. Periods of hydroclimate change like the MCA are thus expected to occur in the AW, although not frequently, with a recurrence interval of approximately 11 000 years. Importantly, a shift in mean hydroclimate conditions during the MCA is found to be necessary for drought to reach the severity and persistence of the actual MCA megadroughts. This result has consequences for our understanding of the atmosphere-ocean dynamics underlying the MCA and a persistently warm Atlantic Multidecadal Oscillation is suggested to have played an important role in causing megadrought clustering during this period.

    2013-01-01

    We investigated the decayed historical church window glasses of two Catalonian churches, both under Mediterranean climate. Glass surfaces were studied by scanning electron microscopy (SEM), energy dispersive spectrometry (EDS), and X-ray diffraction (XRD). Their chemical composition was determined by wavelength-dispersive spectrometry (WDS) microprobe analysis. The biodiversity was investigated by molecular methods: DNA extraction from glass, amplification by PCR targeting the16S rRNA and ITS regions, and fingerprint analyses by denaturing gradient gel electrophoresis (DGGE). Clone libraries containing either PCR fragments of the bacterial 16S rDNA or the fungal ITS regions were screened by DGGE. Clone inserts were sequenced and compared with the EMBL database. Similarity values ranged from 89 to 100% to known bacteria and fungi. Biological activity in both sites was evidenced in the form of orange patinas, bio-pitting, and mineral precipitation. Analyses revealed complex bacterial communities consisting of members of the phyla Proteobacteria, Bacteroidetes, Firmicutes, and Actinobacteria. Fungi showed less diversity than bacteria, and species of the genera Cladosporium and Phoma were dominant. The detected Actinobacteria and fungi may be responsible for the observed bio-pitting phenomenon. Moreover, some of the detected bacteria are known for their mineral precipitation capabilities. Sequence results also showed similarities with bacteria commonly found on deteriorated stone monuments, supporting the idea that medieval stained glass biodeterioration in the Mediterranean area shows a pattern comparable to that on stone.

  14. Efficient removal of foxing from a medieval Ptolemaic map using a molecular fluorine laser at 157 nm

    Cefalas, A. C.; Sarantopoulou, E.; Kollia, Z.

    In this communication, we have used a molecular fluorine laser at 157 nm to remove foxing marks, for the first time, from a medieval Ptolemaic map published in 1580 AD. By applying laser-ablation experimental techniques, the absorption coefficient and the threshold-energy fluence of the paper manuscript were determined . The absorption coefficient at 157 nm was found to be one order of magnitude higher than at 248 nm. There was no evidence of oxidising of the paper substrate following laser treatment of foxing areas at 157 nm (yellowish colour). In order to investigate the basic photo-chemical mechanism of the photo-dissociation dynamics of the paper's cellulose fibres under vacuum ultraviolet irradiation, we applied mass-spectroscopic techniques. Mass spectroscopy reveals that there is breaking of the molecular bonds of the cellulose, even at low laser energy at 157 nm. The cellulose monomer is disintegrated into small photo-fragments, which fly apart with supersonic speed. There were no photo-fragments observed for m/e higher than 32 amu (atomic mass units of m/e). Fragments with two carbon atoms have a relatively higher probability to be dissociated from the parent cellulose molecule than heavier ones. These experimental findings suggest that the bound potential excited electronic states of the parent molecule correlate with dissociative excited electronic states of the molecular photo-fragments at 7.8 eV (λ=157 nm), in agreement with previous results for various organic polymers of similar chemical structure.

    Two sediment cores from Piermont Marsh, located in the southern Hudson River Valley, provide a well-dated bi-decadal record of vegetation, climate, land use, and fire frequency. The classic Medieval Warm Period is evident through striking increases in charcoal and Pinus dominance from A.D.800-1350, paralleling records southward along the Atlantic seaboard. Higher inputs of inorganic sediment during this interval suggest increased watershed erosion during drought conditions. Increases in Picea and Tsuga with corresponding decreases in Liquidambar, coupled with increasing organic percentages due to cooler, moister conditions indicate the presence of the Little Ice Age. European impact is manifested by increased weedy plant cover (i.e., Ambrosia, Plantago, and Rumex), decline in arboreal pollen due to land clearance, and increase in inorganic particles to the watershed. Radionuclide dating using Cs-137 and Pb-210 from the southern end of the marsh shows that little disturbance of sediments has occurred, adding validity to the high resolution results and supporting the sedimentation rates obtained using radiocarbon dating. Comparison with other marsh records in the Hudson River estuary shows general agreement in chronology with interesting differences in species changes and sedimentation rates.

    The West Siberia Lowland is the most carbon-rich northern wetland region, holding an important portion of total northern peatland carbon (70 Gt of 270-450 Gt C) mainly in the southern lowland (44 Gt) in very large peatlands. The largest of these, the Great Vasyugan Bog complex, spans 63,252 km2 and alone holds ~11 Gt C. Our previous work has shown that recent-past growth of WSL peat C pool has been greatest in southern WSL in large peatlands close to the southern limit of peatland distribution. In this study, we investigate a Great Vasyugan site to investigate peat carbon sensitivity in two ways: 1) assess past changes in vegetation, species-specific 13C geochemistry, and rate of carbon accumulation relative to recent-past climate variation, and 2) assess the relative lability of this deep peat C through laboratory incubations. Carbon accumulation over the last 2000 years, a period of relatively consistent vegetation and litter inputs but variable local hydrology, reached a maximum between 1150 and 1350 AD during Medieval Climate Anomaly conditions. A carbon accumulation minimum occurred between about 1350 and 1550 AD. Regardless of depth, age, or rate of carbon burial, deep peat from between 30 and 230 cm below the surface showed a similar rate of potential aerobic respiration that changed little over 42 days of incubation. Taken together, these data suggest that in some peatlanlds warmer and hydrologically-variable conditions can promote long-term belowground carbon storage.

    For a preliminary test of 14C dating of cremated human remains, we have collected charred bone and wood-charcoal fragments from cremated remains contained in cinerary urns that had been excavated from medieval Buddhist cemetery at the Hoenji temple in Aichi prefecture, central Japan. More than 230 urn vessels were discovered from the excavated area of ca. 14 m wide and 14 m long. The identification of charred bone or charcoal fragments among the remains was performed by observation of surface appearance, inspection of fine structures by a microscope, bubble formation during the HCl treatments in preparing target material for AMS 14C dating, carbon and nitrogen contents, δ13C and δ15N values of the fragments. All 14C ages obtained for the samples that were identified as charred bone remains were almost consistent with the archeological age estimated based on typological analysis of respective urns. On the other hand, some 14C ages for the remains identified as wood charcoal, which had been produced from firewood or a wooden coffin during the cremation, were not consistent with archeological estimation, shifting toward older 14C ages, most probably as the result of old wood effect.

    Although recent historical ecology studies have extended quantitative knowledge of eastern Baltic cod (Gadus morhua) exploitation back as far as the 16th century, the historical origin of the modern fishery remains obscure. Widespread archaeological evidence for cod consumption around the eastern Baltic littoral emerges around the 13th century, three centuries before systematic documentation, but it is not clear whether this represents (1) development of a substantial eastern Baltic cod fishery, or (2) large-scale importation of preserved cod from elsewhere. To distinguish between these hypotheses we use stable carbon and nitrogen isotope analysis to determine likely catch regions of 74 cod vertebrae and cleithra from 19 Baltic archaeological sites dated from the 8th to the 16th centuries. δ13C and δ15N signatures for six possible catch regions were established using a larger sample of archaeological cod cranial bones (n = 249). The data strongly support the second hypothesis, revealing widespread importation of cod during the 13th to 14th centuries, most of it probably from Arctic Norway. By the 15th century, however, eastern Baltic cod dominate within our sample, indicating the development of a substantial late medieval fishery. Potential human impact on cod stocks in the eastern Baltic must thus be taken into account for at least the last 600 years. PMID:22110675

    Italian medieval and Renaissance manuscript cuttings and miniatures from the Victoria and Albert Museum were analyzed by Raman microscopy to compile a database of pigments used in different periods and different Italian regions. The palette identified in most manuscripts and cuttings was found to include lead white, gypsum, azurite, lazurite, indigo, malachite, vermilion, red lead, lead tin yellow (I), goethite, carbon, and iron gall ink. A few of the miniatures, such as the historiated capital “M” painted by Gerolamo da Cremona and the Petrarca manuscript by Bartolomeo Sanvito, are of exceptional quality and were analyzed extensively; some contained unusual materials. The widespread usage of iron oxides such as goethite and hematite as minor components of mixtures with azurite is particularly notable. The use of a needle-shaped form of iron gall ink as a pigment rather than a writing material was established by both Raman microscopy and x-ray fluorescence spectroscopy for the Madonna and Child by Franco de’ Russi.

  1. XAFS study of copper and silver nanoparticles in glazes of medieval middle-east lustreware (10th-13th century)

    It has recently been shown that lustre decoration of medieval and Renaissance pottery consists of silver and copper nanoparticles dispersed in the glassy matrix of the ceramic glaze. Here the findings of an X-ray absorption fine structure (XAFS) study on lustred glazes of shards belonging to 10th and 13rd century pottery from the National Museum of Iran are reported. Absorption spectra in the visible range have been also measured in order to investigate the relations between colour and glaze composition. Gold colour is mainly due to Ag nanoparticles, though Ag+, Cu+ and Cu2+ ions can be also dispersed within the glassy matrix, with different ratios. Red colour is mainly due to Cu nanoparticles, although some Ag nanoparticles, Ag+ and Cu+ ions can be present. The achievement of metallic Cu and the absence of Cu2+ indicate a higher reduction of copper in red lustre. These findings are in substantial agreement with previous results on Italian Renaissance pottery. In spite of the large heterogeneity of cases, the presence of copper and silver ions in the glaze confirms that lustre formation is mediated by a copper- and silver-alkali ion exchange, followed by nucleation and growth of metal nanoparticles.

  2. The medieval metal industry was the cradle of modern large-scale atmospheric lead pollution in northern Europe

    There is great concern for contamination of sensitive ecosystems in high latitudes by long-range transport of heavy metals and other pollutants derived from industrial areas in lower latitudes. Atmospheric pollution of heavy metals has a very long history, and since metals accumulate in the environment, understanding of present-day pollution conditions requires knowledge of past atmospheric deposition. The authors use analyses of lead concentrations and stable lead isotopes ({sup 206}Pb/{sup 207}Pb ratios) of annually laminated sediments from four lakes in northern Sweden to provide a decadal record of atmospheric lead pollution for the last 3000 years. There is a clear signal in the sediments of airborne pollution from Greek and Roman cultures 2000 years ago, followed by a period of clean conditions 400--900 A.D. From 900 A.D. there was a conspicuous, permanent increase in atmospheric lead pollution fallout, The sediments reveal peaks in atmospheric lead pollution at 1200 and 1530 A.D. comparable to present-day levels. These peaks match the history of metal production in Europe. This study indicates that the contemporary atmospheric pollution climate in northern Europe was established in Medieval time, rather than in the industrial period. Atmospheric lead pollution deposition did not, when seen in a historical perspective, increase as much as usually assumed with the Industrial Revolution.

    Analysis of DNA from archeological remains is a valuable tool to interpret the history of ancient animal populations. So far most studies of ancient DNA target mitochondrial DNA (mtDNA), which reveals maternal lineages, but only partially the relationships of current breeds and ancient populations. In this study we explore the feasibility of nuclear DNA analysis. DNA was extracted from 1000-years old cattle bone collected from Ferento, an archeological site in central Italy. Amplification of 15 microsatellite FAO-recommended markers with PCR products yielded genotypes for four markers. Expected heterozygosity was comparable with values of modern breeds, but observed heterozygosity was underestimated due to allelic loss. Genetic distances suggested a position intermediate between (1) Anatolian, Balkan, Sicilian and South-Italian cattle and (2) the Iberian, North-European and Central-European cattle, but also a clear relationship with two central-Italian breeds, Chianina and Romagnola. This suggests that these breeds are derived from medieval cattle living in the same area. Our results illustrate the potential of ancient DNA for reconstructing the history of local cattle husbandry.

    Since natural textiles usually originate from short-lived organisms, they can represent a useful material to date samples from historical periods with a good accuracy. In this work, we present a set of radiocarbon measurements on medieval textile relics: two woollen habits and a pillow traditionally associated with St. Francis of Assisi, the saint patron of Italy. The strategy in choosing samples for radiocarbon dating is first discussed and the procedures for measurements - performed at the 3 MV Tandetron accelerator of Laboratorio di Tecniche Nucleari per i Beni Culturali (LABEC), Florence - are described; AMS results for the two frocks showed that only one of them, presently kept in the church of St. Francis in Cortona, is compatible with the Saint's period of life, as is the pillow also kept in Cortona. Another frock attributed to St. Francis appears to date from at least 80 years after his death. However, the goal of these measurements was not a bare authentication/disconfirmation of the relics; they just represent an example of how scientific analysis can integrate with humanistic studies. Indeed, AMS results, combined with a thorough analysis of the textiles typologies, confirmed the historical hypotheses based on documentary studies and on tradition. The overall conclusions contributed to the decisions taken for conservation, and have as a whole enhanced the religious importance of the relics.

    There are written some doctrines about growth image of embryo and fetus, hygiene for woman on each month during pregnancy period etc. in ancient Chinese medical book the Taichan Shu, which compiled over 2200 years ago. Following results were obtained by a study on the transition doctrines from that of Taichan Shu to those of medieval Chinese and Japanese medical books such as the Zhubing Yuanhou Lun, the Qianjin Fang and the Ishin Po. (1) Doctrines about growth and hygiene on embryo and fetus had been developed on each coming book from the contents of the Taichan Shu descent. Doctrines about hygiene were mainly for pregnant woman, and some methods of them were told by using figure image and the five elements theory in the part. (2) There could be found additional doctrines about meridian and internal organs theory in the Zhubing Yuanhou Lun, the Qianjin Fang and the Ishin Po. And those additional doctrines were made under the influence of the Maijing and the Suwen. New doctrines about hygiene for pregnant woman found in the Qianjin Fang and the Ishin Po also have relationships with meridian and internal organs theory. (3) Growing organs of embryo and fetus described in the Zhubing Yuanhou Lun and the Qianjin Fang correspond with the internal organs theory. Purpose of those descriptions is estimated to be equipped much more organs for embryo and fetus than those of the Taichan Chu.

    Infrared reflectography, i.e. the use of images taken with infrared light, is currently applied in the field of cultural heritage mainly for paintings analysis to reveal the presence of underdrawings or alterations. Its use in archaeology for deciphering faded signs (texts, images, tattoos, etc.) is a lot more limited and in most cases no or simple data analysis and elaboration is performed. Here we show that infrared reflectography taken by using a wide spectral response (wavelength range from 400 to 2200 nm) VIDICON image acquisition system together with adequate post-elaboration, taking advantage from advanced techniques for data analysis (wavelet decomposition) and image registration and fusion, is able to produce high-quality ‘C&IR’ images. Such images can be obtained in a relatively easy way using the same hardware configuration generally used for infrared reflectographic analysis of paintings. The application to a medieval capsella (a small wooden relics container) from Cimitile, Italy, has shown that these results are of great interest for archaeologists.

    Several optimization techniques have been applied to the solution of the thermal unit commitment problem. They range from heuristics such as complete enumeration to the more sophisticated ones such as Augmented LaGrangian. The heuristics have even reappeared as expert systems. The problem to solve is the optimal scheduling of generating units over a short-term horizon, typically 168 hours. This paper is an overview of the literature in the unit commitment field over the past twenty five years.

    In this article it is argued that feelings are all important to the function of literature. In contradiction to music that is concerned with the inwardness of humankind, literature has, because of language, the capacity to create fictional worlds that in many respects are similar to and related to the life world within which we live. One of the most important reasons for our emotional engagement in literature is our empathy with others and our constant imagining and hypothesizing on possible developments in our interactions with them. Hence, we understand and engage ourselves in fictional worlds. It is further claimed and exemplified, how poetic texts are very good at rhetorically engage and manipulate our feelings. Finally, with reference to the important work of Ellen Dissanayake, it is pointed out that the first kind of communication in which we engage, that between mother and infant, is a kind of speech that positively engages the infant in a dialogue with the mother by means of poetic devices.

The recipes are organised broadly from head to toe, and often several remedies are offered for the same complaint. Some individual recipes are transcribed with modern English translations. The few non-recipe texts are also noted. The difference between a remedy book and a leechbook is explained, and this manuscript is situated in relation to other known examples of late medieval medical anthologies. The particular feature that distinguishes Oxford, Bodleian Library, Rawlinson c. 299 from other similar volumes is the evidence that it continued to be used during the sixteenth century. This usage was of two kinds. Firstly, the London lawyer who owned it not only inscribed his name but annotated the original recipe collection in various ways, providing finding-aids that made it much more user-friendly. Secondly, he, and other members of his family, added another forty-three recipes to the original collection (some examples of these are also transcribed). These two layers of engagement with the manuscript are interrogated in detail in order to reveal what ailments may have troubled this family most, and to judge how much faith they placed in the old remedies contained in this old book. It is argued that the knowledge preserved in medieval books enjoyed a longevity that extended beyond the period of the manuscript book, and that manuscripts were read and valued long after the advent of printing.

  15. A medieval fallacy: the crystalline lens in the center of the eye

    2016-01-01

    Objective To determine whether, as most modern historians have written, ancient Greco-Roman authors believed the crystalline lens is positioned in the center of the eye. Background Historians have written that statements about cataract couching by Celsus, or perhaps Galen of Pergamon, suggested a centrally located lens. Celsus specifically wrote that a couching needle placed intermediate between the corneal limbus and the lateral canthus enters an empty space, presumed to represent the posterior chamber. Methods Ancient ophthalmic literature was analyzed to understand where these authors believed the crystalline lens was positioned. In order to estimate where Celsus proposed entering the eye during couching, we prospectively measured the distance from the temporal corneal limbus to the lateral canthus in 30 healthy adults. Results Rufus of Ephesus and Galen wrote that the lens is anterior enough to contact the iris. Galen wrote that the lens equator joins other ocular structures at the corneoscleral junction. In 30 subjects, half the distance from the temporal corneal limbus to the lateral canthus was a mean of 4.5 mm (range: 3.3–5.3 mm). Descriptions of couching by Celsus and others are consistent with pars plana entry of the couching needle. Anterior angulation of the needle would permit contact of the needle with the lens. Conclusion Ancient descriptions of anatomy and couching do not establish the microanatomic relationships of the ciliary region with any modern degree of accuracy. Nonetheless, ancient authors, such as Galen and Rufus, clearly understood that the lens is located anteriorly. There is little reason to believe that Celsus or other ancient authors held a variant understanding of the anatomy of a healthy eye. The notion of the central location of the lens seems to have arisen with Arabic authors in 9th century Mesopotamia, and lasted for over 7 centuries. PMID:27114699

    Parafunctional activities associated with the stomatognathic system include lip and cheek chewing, nail biting, and teeth clenching. Bruxism can be classified as awake or sleep bruxism. Patients with sleep bruxism are more likely to experience jaw pain and limitation of movement, than people who do not experience sleep bruxism. Faulty occlusion is one of the most common causes of bruxism that further leads to temporomandibular joint pain. Bruxism has been described in various ways by different authors.

    The published literature on cosmic electrons is summarized. The primary and secondary sources of cosmic electrons are discussed, and the propagation of the electrons in the interstellar medium is studied with respect to energy loss mechanisms, age distributions, and spectral modifications during flight. Various portions of the electron and positron spectra are then considered in relation to problems of astrophysics. New information is presented on such topics as the origin of low-energy positrons, the decay kinematics of the pi-mu-e process, the application of age distributions for nuclear cosmic rays to cosmic electrons, and the possibility of nonidentical sources for cosmic electrons and protons.

  18. Interdisciplinary landscape research in a medieval mound in one of the oldest Dutch towns, Vlaardingen, the Netherlands

    2013-04-01

    In Medieval times the city of Vlaardingen (the Netherlands) was strategically located on the confluence of three rivers, the Meuse, the Merwede and the Vlaarding. A church of early 8th century was already located here. In a short period of time Vlaardingen developed into an international trading place, the most important place in the former county of Holland. Starting from the 11th century the river Meuse threatened to flood the settlement, and as a reaction to it inhabitants started to raise the surface. This resulted eventually in an enormous mound, surface: 200 by 250 meter, built up in a four to five meter thick sequence of clay and manure in which organic rests of former occupation are extremely well preserved, e.g. wooden posts, mesh walls, but also leather objects. Early 2002 graves were found in the city centre, dating 1000-1050, in which not only the wooden coffins, but also the straw that covered the deceased. In human teeth DNA appeared to be well preserved, classified as the oldest in the nation, turning the church hill into a large database of human DNA. To secure the future of this vulnerable soil archive currently an extensive interdisciplinary research (mechanical drilling, grain size, TGA, archeological remains, osteology, hydrology, dating methods, micromorphology, microfauna, molluscs, diatoms) has started in 2011 to gain knowledge on the internal structure of the mound as well as on the well-preserved nature of the archaeological evidence. In this presentation the results of this large-scale project are demonstrated in a number of cross-sections with interrelated geological and archaeological stratification. Results of GSA (including end-member analysis EMMA), TGA, XRF and micromorphology analyses are presented. Distinction between natural and anthropogenic layering is made on the occurrence of chemical elements phosphor and potassium. Results of this research are also applied in the construction of the 3D model of the subsurface (this session

    Microthermometric investigations of silicate-melt inclusions and electron microprobe analyses were conducted on experimentally homogenized silicate-melt inclusions and on the host clinopyroxenes from 4 scoria samples of different layers from the Mt. Somma-Vesuvius medieval eruption (Formazione di Terzigno, 893 A.D.). The temperature of homogenization, considered the minimum trapping temperature, ranges from 1190 to 1260??5 ??C for all clinopyroxene-hosted silicate melt inclusions. The major and minor-element compositional trends shown by Terzigno scoria and matrix glass chemical analysis are largely compatible with fractional crystallization of clinopyroxene and Fe-Ti oxides. Sulfur contents of the homogenized silicate-melt inclusions in clinopyroxene phenocrysts compared with that in the host scoria show that S has been significantly degassed in the erupted products; whereas, Cl has about the same abundance in the inclusions and in host scoria. Fluorine is low (infrequently up to 800 ppm) in the silicate-melt inclusions compared to 2400 ppm in the bulk scoria. Electron microprobe analyses of silicate-melt inclusions show that they have primitive magma compositions (Mg# = 75-91). The composition of the host clinopyroxene phenocrysts varies from typical plinian-related (Mg#???85) to non-plinian related (Mg#???85). The mixed source of the host clinopyroxenes and primitive nature of the silicate-melt inclusions implies that these phenocrysts, in part, may be residual and/or have a polygenetic origin. The similar variation trends of major and minor-elements between homogenized silicate-melt inclusions from the Terzigno scoria, and silicate-melt inclusions in olivine and diopside phenocrysts from plinian eruptions (Marianelli et al., 1995) suggest that the trapped inclusions represent melts similar to those that supplied the plinian and sub-plinian magma chambers. These geochemical characteristics suggest that the Vesuvius magmatic system retained a vestige of the most

    During the past ~8000 years the Baltic Sea has experienced three distinct intervals of hypoxia, of which the last one is still ongoing. These intervals are characterized by enhanced sedimentary organic matter burial and enrichment of redox-sensitive metals, such as molybdenum and iron. The first two of these intervals occurred during the Holocene Thermal Maximum (HTM) and the Medieval Climate Anomaly (MCA), two phases with high temperatures and changed precipitation patterns. Studies focussing on the Holocene sedimentary record of the Baltic Sea aim at clarifying the causes of the initiation, evolution and termination of these hypoxic intervals, as well as their consequences. This information could help to potentially aid in finding solutions for the mitigation of present-day hypoxia in the Baltic Sea. The factors contributing to hypoxia development during the HTM and MCA are still debated. Here we present data from a core retrieved during Integrated Ocean Drilling Program (IODP) Expedition 347 in the Landsort Deep basin, the deepest basin of the Baltic Sea at 463m water depth. Sediments were analysed at a high resolution using inorganic geochemical and (mainly marine) palynological proxies. Dinoflagellate cyst (dinocyst) assemblages and total elemental compositions provide clues on the role of salinity in enhancing stratification, ultimately causing hypoxia. During the onset of the HTM changes in salinity, as indicated by the palynology, closely follow changes in sedimentary organic carbon burial and trace metal concentrations. This suggests that stratification was an important cause of hypoxia during the HTM. In contrast, the palynology suggests that reduced stratification did not contribute to re-oxygenation during the termination of the HTM. We did not observe major changes in the palynology throughout the hypoxic interval of the MCA. Our results thus suggest that changes in salinity did not cause the onset and termination of hypoxia during the MCA.

    Ruminant milk and dairy products are important food resources in many European, African, and Middle Eastern societies. These regions are also associated with derived genetic variants for lactase persistence. In mammals, lactase, the enzyme that hydrolyzes the milk sugar lactose, is normally down-regulated after weaning, but at least five human populations around the world have independently evolved mutations regulating the expression of the lactase-phlorizin-hydrolase gene. These mutations result in a dominant lactase persistence phenotype and continued lactase tolerance in adulthood. A single nucleotide polymorphism (SNP) at C/T-13910 is responsible for most lactase persistence in European populations, but when and where the T-13910 polymorphism originated and the evolutionary processes by which it rose to high frequency in Europe have been the subject of strong debate. A history of dairying is presumed to be a prerequisite, but archaeological evidence is lacking. In this study, DNA was extracted from the dentine of 36 individuals excavated at a medieval cemetery in Dalheim, Germany. Eighteen individuals were successfully genotyped for the C/T-13910 SNP by molecular cloning and sequencing, of which 13 (72%) exhibited a European lactase persistence genotype: 44% CT, 28% TT. Previous ancient DNA-based studies found that lactase persistence genotypes fall below detection levels in most regions of Neolithic Europe. Our research shows that by AD 1200, lactase persistence frequency had risen to over 70% in this community in western Central Europe. Given that lactase persistence genotype frequency in present-day Germany and Austria is estimated at 71-80%, our results suggest that genetic lactase persistence likely reached modern levels before the historic population declines associated with the Black Death, thus excluding plague-associated evolutionary forces in the rise of lactase persistence in this region. This new evidence sheds light on the dynamic evolutionary

    River landscapes are, since they are cultivated and inhabited by humans, among the most densely populated areas in the world. These landscapes provide fertile substrates, natural resources (e.g. food, raw materials), and abundant water routes for long-distance transport. However, these wet and dynamic landscapes often pose challenges to the people. In the past this sometimes even led to the relocation of production areas and settlements to more suitable areas. In the fluvial dominated part of the Rhine-Meuse delta, The Netherlands, the late-Roman and early-medieval periods (AD 270 - 1050) are characterized by both cultural changes (e.g. in demography, settlement location) and environmental changes (river avulsions, changes in flooding frequency). In the delta plain, the relatively high and dry natural levees were most favourable for habitation. The extension and relative elevation of these important landscape units has recently been mapped in high detail, exploring the distribution of settlements on these landscape units and the changing patterns of settlements through time is the next step. To perform this, we need to integrate the geomorphological reconstructions with archaeological datasets. We have applied a multidisciplinary approach by integrating new high-resolution palaeoenvironmental reconstructions with archaeological datasets. Our aims were to: 1) determine the spatial distribution of settlements on geomorphological landscape units, and 2) explore changes in human-environment interactions from the late Roman period to the Early Middle Ages. In this contribution, we present the first results of these analyses. Integrating these datasets is an important step towards further understanding of the relative contribution of (and the interaction between) environmental and cultural factors in determining settlement distribution in the Rhine-Meuse delta.

    Early Medieval England is described historically as a time when people migrated from the Continent to English shores. This study tests the hypothesis that those buried in the Bowl Hole cemetery, Bamburgh, Northumberland were nonlocally born, because of its royal status. Ninety-one male and female adult, and nonadult, skeletons were studied. Isotope ratios of strontium ((87) Sr/(86) Sr) and oxygen (δ(18) O) were generated for 78 individuals (28 females, 27 males, five "adults," 18 nonadults). The mean Sr value for human enamel was 0.71044, standard deviation (sd) 0.001, and the mean O (δw) value is -5.9‰, sd 1.6‰. Additionally, animal tooth enamel (mean Sr value 0.710587, sd 0.001; mean O value -6.5‰, sd 1.5‰), local soil (mean Sr value 0.709184, sd 0.0006), snail shells (mean Sr value 0.708888, sd 0.0001), and soil samples from a 5 km transect heading inland (mean Sr value 0.709121, sd 0.0003), were analyzed for an indication of the isotopic composition of bioavailable Sr in the modern environment and to assess the impact of sea-spray; water samples from a well, local rivers, and standing water were analyzed for local δ(18) O values (mean O value -6.4‰, relative to VSMOW, sd 2.8‰). Over 50% of those buried at Bamburgh were nonlocal. All ages and both sexes produced "nonlocal" signatures; some suggested childhood origins in Scandinavia, the southern Mediterranean or North Africa. Stature and other indicators of health status indicated differences in quality of life between local and migrant groups. These differences did not extend to burial practices.

    The objective of this paper is: (a) to present a rating scale for the evaluation of the musculoskeletal stress markers; (b) to analyze the medieval population from Cedynia in terms of the degree of expression and frequency of the musculoskeletal stress markers. The presented rating scale was developed based on the variability of the morphology of muscle attachment sites, observed in the skeletal material from Cedynia (102 males and 99 females). The scale encompasses 10 musculoskeletal stress markers located on the scapula, humerus, radius, femur and tibia. The system reflects three degrees (1, 2, 3) of complexity of the muscle attachment sites morphology. The analysis of asymmetry and sexual dimorphism of the musculoskeletal stress markers was made based on the chi2 (Pearson) statistics or chi2 statistics for 2 x 2 tables. Moderate degree (2) of muscle attachment site complexity is the most frequent degree of musculoskeletal stress markers development in the population from Cedynia. Low (1) and high (3) complexity of muscle attachment site are the most seldom observed categories. No statistically significant differences between the frequencies of the musculoskeletal stress markers on the bones of the right and left side of the skeleton were noted in females. Also in males the differences found were not statistically significant. Only in the case of deltoid tuberosity (H2) p = 0.052 oscillating around the threshold value may suggest existence of a statistically significant difference in the degree of expression of this stress marker on the bone of the right and left side of the skeleton. On the bones of the right side of the skeleton dimorphic differences were observed in the glenoid tuberosity (S2), bicipital groove (H1), pronator teres origin (R2), tibial tuberosity (T1), soleal crest (T2) and linea aspera (F2). On the bones of the left side of the skeleton dimorphic differences were noted for the bicipital groove (H1), pronator teres origin (R2) and glenoid

    High-resolution δ18O data (yearly) since AD 900 from six caves (Dongge, Furong, Heshang, Wanxiang, Buddha, Shihua) in China was analyzed to detect decadal and centennial variability of wet/dry in the Asian Monsoon region. The empirical mode decomposition method (Huang et al., 1998) was used to obtain trends for the six cave data. The nine-year running average was conducted on the detrened data (Δδ18O, called anomaly) to filter out high-frequency fluctuation such as the interannual variability. Mean values of anomaly for each cave were calculated for 5 periods: (1) medieval warm period (MWD, AD 900 -AD 1100), (2) little ice age phase-1 (LIA-1, AD 1250 - AD 1550), (3) little ice age phase-2 (LIA-2, AD 1550 - AD 1850), (4) modern period-1 (MD-1, AD 1850 - AD 1950), and (5) modern period-2 (MD-2, AD 1950-2000). Anomalies in MWP and LIA-2 has opposite signs: negative anomaly (strong monsoon) in MWP and positive anomaly (weak monsoon) in LIA-2 in (Dongge, Wanxiang) cave data otherwise in (Budda, Furong, Heshang, Shihua) cave data. In LIA-1, all the six caves have positive anomalies (weak monsoon). In MD-1 (AD 1850-AD 1950), all the six caves have negative anomalies; and in MD-2 (AD 1950 - AD 2000), all the caves except Buddha have negative anomalies. It implies strong monsoon with global warming trend. Spectral analysis was also conducted on the detrended data of the six caves. The above observational studies show the following results: (1) Monsoon strength has spatial variations; (2) Stronger monsoon occurred under both warm and cold climatic conditions. One should not use the relationship of warm condition, i.e., stronger summer monsoon to interpret monsoonal climates in short time scales (less than centennial scale); and (3) Monsoon strengthening continues.

    Photons, electrons and protons beams applied to the scientific investigation of archaeological materials provide complementary information for characterising the state of preservation and the provenance of the objects. Investigations were carried out on medieval silver coins of the "Friesacher Pfennig" and the "Tiroler Kreuzer" from the Kunsthistorisches Museum Vienna and the Oesterreichische Nationalbank. Techniques employed were EDXRF, SEM/EDX and PIXE. By determining the trace elements of the alloys it was possible to assign coins to their mint. The results outline advantages and disadvantages of EDXRF, SEM/EDX and PIXE when applied to corroded objects.

    Reconstructing late-Holocene hydroclimatic variations can be useful to understand the sensitivity of peatland soil carbon (C) to climate change (Bunbury et al., 2012). We reconstructed water table depth (WTD), using testate amoebae, for a four-core north to south transect of the James Bay Lowland and Boreal Shield of Ontario, Canada, and compared WTD to long-term apparent rate of C accumulation (LARCA). The three southern sites indicate that WTD fluctuated relative to the mean, with a wetter Medieval Climate Anomaly (MCA) and drier Little Ice Age (LIA) (Fig. 1). However, the most northern site recorded a wet LIA and dry MCA (Fig. 1). All four cores recorded drying coincident with modern warming (Fig. 1). Increased Medieval moisture detected in the three southern sites is consistent with a geographic pattern of precipitation anomalies associated with La Niña-like conditions, which cause drought in the American southwest and central plains regions coupled with increased moisture in the Pacific Northwest and north of the Great Lakes (Feng et al., 2008; Seager et al., 2008). Despite the hydroclimatic sensitivity of the region, we observed no consistent relationship between variations in WTD and LARCA from the same cores. At these particular sites, at least, C accumulation has not been sensitive to the range of climatic variability associated with the MCA, LIA and recent warming. Bunbury, J., Finkelstein, S.

    The hypothesis of this study was that a multidisciplinary, activity rich science curriculum based around science fiction literature, rather than a conventional text book would increase student engagement with the curriculum and improve student performance on standards-based test instruments. Science fiction literature was chosen upon the basis of previous educational research which indicated that science fiction literature was able to stimulate and maintain interest in science. The study was conducted on a middle school campus during the regular summer school session. Students were self-selected from the school's 6 th, 7th, and 8th grade populations. The students used the science fiction novel Maurice on the Moon as their only text. Lessons and activities closely followed the adventures of the characters in the book. The student's initial level of knowledge in Earth and space science was assessed by a pre test. After the four week program was concluded, the students took a post test made up of an identical set of questions. The test included 40 standards-based questions that were based upon concepts covered in the text of the novel and in the classroom lessons and activities. The test also included 10 general knowledge questions that were based upon Earth and space science standards that were not covered in the novel or the classroom lessons or activities. Student performance on the standards-based question set increased an average of 35% for all students in the study group. Every subgroup disaggregated by gender and ethnicity improved from 28-47%. There was no statistically significant change in the performance on the general knowledge question set for any subgroup. Student engagement with the material was assessed by three independent methods, including student self-reports, percentage of classroom work completed, and academic evaluation of student work by the instructor. These assessments of student engagement were correlated with changes in student performance

    Compadrazgo, "coparenthood," is a traditional ritual fictive kinship system that provides a network of mutually supportive relationships in the Mexican American culture. A literature search of CINAHL, Medline, PsychoInfo, and Web of Science was used to identify peer-reviewed journals and original sources. Keywords included comadre, compadrazgo, fictive kin, social support, Mexican, and Mexican American. Additional resources were identified through a focused review of references. Findings from this study indicate knowledge about compadrazgo, is limited to the social organization, historical practices, and a preliminary description of the compadres role. Minimal information is available about the relationship between compadrazgo, and health, and variations in roles and responsibilities of compadrazgo, participants. Frequency of enactment of compadrazgo, responsibilities and barriers to the enactment of social support by compadres remain unknown. Variations in practice have not been explored. Nursing implication include the recommended ways that compadrazgo, can be encouraged or promoted in patient care. PMID:22267550

    In this paper, we present new data from 226Ra-230Th dating and archaeomagnetism with the aim of improving the knowledge of the flank eruptions that occurred at Mt Etna during the Greek-Roman and Early Medieval periods, as defined in the new geological map of the volcano. The combination of the two dating techniques demonstrates that three major flank eruptions occurred on the lower north and west flanks during Greek-Roman epochs, producing large scoria cones and extensive lava flows. In particular, the Mt Ruvolo and Mt Minardo events highly impacted the territory of the west flank, notably by damming the Simeto River. The new data of the Millicucco and Due Monti lava flows, on the lower north-east flank, indicate a younger age than their stratigraphic ages quoted in the 2011 geological map, since they occurred around 700 and 500 AD, respectively. None of the large flank eruptions occurring on the lower slopes of Etna during the Early Medieval age are reported in the historical sources. Overall, our paper shows that a comprehensive assessment of eruptions at Mount Etna in the last three millennia can only be achieved through a multidisciplinary approach.

    Due to the variability of the Little Ice Age (LIA) and Medieval Climatic Anomaly (MCA), several climatic forcing mechanisms have been invoked to enlighten the issue. The focus of this study is on the influence of the solar activity proxy (Total Solar Irradiance) during the LIA and MCA in a high altitude Lake Salda in south-western Anatolia. In order to understand this, we recovered 5 gravity cores with various lengths and from various locations in the lake. We used high-resolution multi proxy approach which includes Itrax XRF scanner at a resolution of 2mm, Multi Sensor Core Logger (MSCL) at a resolution of 5 mm and TOC/TIC analysis at a resolution of 30 mm. 210Pb-137Cs methods were employed for dating and afterwards were tuned with solar activity proxy (Total Solar Irradiance) data for age improvement. As a result, the sediment records cover the last millennium. We have observed the effect of the solar activity throughout the LIA and MCA in Lake Salda, with wet and dry spells corresponding to high and low TSI respectively. In addition, the Dalton Minimum, Maunder Minimum, Spörer Minimum, Wolf Minimum, the Medieval Maximum and the Oort Minimum have been observed.

    Peatland vegetation is controlled primarily by the depth of the water table, making peat paleovegetation a useful climate archive. We applied a biochemical approach to quantitatively estimate the plant sources of peat carbon based on (1) neutral sugar compositions of Sphagnum, vascular plants, and lichens and (2) lignin phenol compositions of vascular plants. We used these biochemical indices to characterize vegetation change over the last 2000 years in four peat cores from the West Siberian Lowland (Russia) to investigate climate change during the Medieval Climate Anomaly and Little Ice Age. The vegetation was dominated by Sphagnum in all four cores, but was punctuated by several rapid but transient transitions to vascular plant dominance in the two cores from the southern West Siberian Lowland (<60°N latitude). Lichen contributions were evident at the end of the Medieval Climate Anomaly and during the Little Ice Age in the two cores from northern West Siberian Lowland (>60°N), possibly indicating permafrost development. However, there was no evidence for sustained vegetation change in response to either climatic event in cores from southern West Siberian Lowland. This suggests that these climatic events were relatively mild in the southern West Siberian Lowland, although the sensitivity of bog plant communities to climate change remains poorly understood.

    This second paper on medieval descriptions and doctrines of stroke reviews concepts outlined by famous Muslim physicians of the Middle Ages such as Rhazes, Haly Abbas, Avicenna, and Averroes. Contrary to a popular belief, Islamic neurological texts represent not only a bridge between ancient and western medieval medical knowledge, but also document remarkable advancements. Whereas statements on diagnosis and prognosis lack originality, the endeavors of physician-philosophers and medical authors led to substantial additions and important changes in theory. Such modifications include the integration of ventricular doctrine and particularly the attempt to unify Aristotelian and Galenic tenets which resulted in a complex discussion about the seats and causes of apoplexy. The fairly simple model handed down by Galenists of the Byzantine period was replaced by more detailed classifications, which proposed "cerebral" as well as "vascular" origins of the disease without suggesting a "cerebrovascular" etiology. Islamic therapeutic strategies included dietetic, pharmacological and surgical elements. The use of the cautery in "chronic apoplexy" was a special feature of Arabic surgery. PMID:11623841

  5. Provenance determination of buntsandstein artefacts from the early-medieval dorestad trading site (the Netherlands): an example of the significance of geological-mineralogical analysis in archaeology

    Mader, Detlef; Kars, Henk

    From the Early-Medieval Dorestad trading site (The Netherlands) which flourished between AD 700 and 850, artefacts made of a variety of rock types were excavated. The rich suite of Early-Medieval object types includes querns, mortars, weights, rotating grindstones, cup-like objects and a Roman altar stone which are partly or completely made of Buntsandstein raw material. Other Early-Medieval artefacts such as whetstones, sarcophagi, touchstones and wells do not consist of Buntsandstein material at all. The suite of Late-Medieval objects which is found at the same place includes sarcophagi, cannon-balls, mortars, roofing-tiles, disc-shaped objects and ornamental stones which exclusively consist of materials other than Buntsandstein rocks. The provenance regions of the various lithofacies comprise near, moderately far and very remote areas. Petrographical analysis of the Buntsandstein samples deriving from both artefacts and accompanying stones without working traces makes it possible to distinguish nine rock types. Rock types I and II which occur most frequently are assigned to the Middle Buntsandstein Karlstal-Schichten and the Upper Buntsandstein Kyllburg-Schichten and Voltziensandstein of the Eifel, respectively. Rock type III which is only represented by two rotating grindstones among the artefacts is correlated with the Middle Buntsandstein Solling-Folge in the Solling. The other rock types cannot be assigned to specific provenance regions, but these are quantitatively of very minor importance. In the light of the petrographical results, the distribution of lithologies among the Buntsandstein artefacts from Dorestad is shown to vary with object type which indicates several source areas for the material deriving from the Buntsandstein; this could imply that the material was already partially introduced in worked condition to Dorestad. The presence of the large Roman altar fragment, however, suggests that a considerable amount of the artefacts consisting of Eifel

    As part of the Filtration task EM-31, WP-2.3.6, which is a joint effort between Savannah River National Laboratory (SRNL) and the Pacific Northwest National Laboratory (PNNL), tests were planned to evaluate crossflow filtration in order to the improve the use of existing hardware in the waste treatment plants at both the Department of Energy (DOE) Savannah River Site (SRS) and Hanford Site. These tests included experiments to try different operating conditions and additives, such as filter aids, in order to create a more permeable filter cake and improve the permeate flux. To plan the SRNL tests a literature review was performed to provide information on previous experiments performed by DOE laboratories, and by academia. This report compliments PNNL report (Daniel, et al 2010), and is an attempt to try and capture crossflow filtration work performed in the past that provide a basis for future testing. However, not all sources on crossflow filtration could be reviewed due to the shear volume of information available. In this report various references were examined and a representative group was chosen to present the major factors that affect crossflow filtration. The information summarized in this review contains previous operating conditions studied and their influence on the rate of filtration. Besides operating conditions, other attempted improvements include the use of filter aids, a pre-filtration leaching process, the backpulse system, and various types of filter tubes and filter coatings. The results from past research can be used as a starting point for further experimentation that can result in the improvement in the performance of the crossflow filtration. The literature reviewed in this report indicates how complex the crossflow issues are with the results of some studies appearing to conflict results from other studies. This complexity implies that filtration of mobilized stored waste cannot be explained in a simple generic sense; meaning an empirical

    Southern California has a Mediterranean-type climate characterized by warm, dry summers associated with the seasonal position of the North Pacific High and cool, wet winters primarily associated with cyclonic storms originating in the high latitude North Pacific. Extreme precipitation events in the region are associated, however, with strong zonal flow that brings warm, moist tropical air across the Pacific (atmospheric rivers). Here we present an ultra-high resolution reconstruction of riverine input (via scanning XRF elemental composition of bulk sediments) into Santa Barbara Basin during the Medieval Climate Anomaly (MCA) and transition into the Little Ice Age (LIA) from a series of kasten cores collected in 2009 by the RV Sproul. We compare precipitation shifts in the region with the response of marine biota to ocean circulation change during the same interval to demonstrate that not all droughts in the America Southwest are associated with the same atmospheric and ocean circulation conditions. Droughts are expressed in Santa Barbara Basin sediments by low concentrations of elements associated with lithogenic sediment (Ti, K, Al and Fe) and were centered at 890, 980, 1140 and 1450 AD. The SBB droughts of the MCA were interrupted by flood events at ˜1270 AD and ˜1380 AD ± 15 which were associated with a dramatic increase in the abundance of the subpolar planktonic foraminiferal sp. Neoglobogerina pachyderma (sinistral). Although variable, this interval dominated by a foraminiferal species preferring water <10°C lasted from ˜1275 to 1340 AD with a brief return to dominantly subtropical planktonic foraminferal species between 1340 and 1400 AD before the foraminiferal assemblage shifted toward cooler subpolar species again until >1500 AD. Of the major Native American population declines during the MCA coincident with drought conditions (990-1060 AD, 1135-1170 AD and 1276-1297 AD) in the Western US (Benson et al., 2007), only the last decline associated with

    The temporomandibular joint (TMJ) is one of the most complex joints in the human body. The anatomical configuration of the TMJ allows for a large range of mandibular movements as well as transmission of masticatory forces and loads to the skull base. The measurements of the TMJ's anatomical structures and their interpretations contribute to the understanding of how pathological changes, tooth loss, and the type of diet (changing throughout human history) can affect biomechanical conditions of the masticatory system and the TMJ. The human TMJ and its constituent parts are still the subject of extensive investigation and comparisons of measurement methods are being made in order to determine the most precise and suitable measurement methods. The aim of this study has been to examine the morphology of skeletal components of TMJ of an early medieval population (EMP) in Croatia and to compare measured values with TMJ values of the contemporary Croatian population (CP) using various methods of measurement. The study was performed on 30 EMP specimens - human dry skulls, aged from 18 to 55 years, and 30 CP human dry skulls, aged from 18 to 65 years. Only fully preserved specimens (in measured areas) were included. The articular eminence (AE) inclination was measured in relation to the Frankfurt horizontal using two methods. Also, the AE height (glenoid fossa depth) and the length of the curved line - highest to the lowest point of the AE were measured. Measurements were performed on lateral skull photographs, panoramic radiographs and lateral cephalograms using VistaMetrix software on skull images. The results were statistically analyzed using SPSS statistical software. No statistically significant differences were obtained for AE parameters between the EMP and CP populations independent of age and gender. However, statistically significant (p<0.05) differences were revealed when comparing results of three different measuring methods. It could not be determined which of

    Peatlands are among the largest reservoirs of terrestrial carbon (C) in the northern hemisphere. Understanding how this carbon pool will respond to climate changes is critical to assessing potential earth-system feedbacks. Peatland C accumulation is controlled by the relative rates of production and decomposition, and the rate of these processes is affected by many factors, including temperature, hydrology, and vegetation. In order to better understand the potential influences of past climate change on C accumulation, we developed a coupled study of peatland paleohydrology and C accumulation from a Sphagnum-dominated peatland located in a glaciated valley south of the Alaska Range in southcentral Alaska. Past responses of this peatland to well-documented climate and temperature changes, like the Medieval Climate Anomaly (MCA) at 1000-600 cal yr BP and Little Ice Age (LIA) at 600-100 cal yr BP, were investigated using water-table depths inferred from testate amoebae and C accumulation rates calculated from loss-on-ignition and 14C-dating analyses. Although warmer temperatures, like those experienced in Alaska during the MCA, might be expected to result in lower water tables and reduced C accumulation, our results indicate that the peatland C accumulation rate during the MCA (~150 gC/m2/yr) was about three times greater than during the LIA (~50 gC/m2/yr). Also, reconstructed water-table depths indicate relatively wet conditions on the peatland during the MCA, suggesting that this region may have experienced increased precipitation during this time, or increased melting of glaciers. Although glacier meltwater was not hydrologically connected to the peatland, it may have led to greater relative humidity that mediated potential drying associated with warmer temperatures. We found that the average ash-free bulk density values during the MCA (0.128 g/cm3) were lower than the average values during the LIA (0.172 g/cm3), consistent with our reconstructed water-table depths

  10. Charcot in contemporary literature.

    PubMed

    Goetz, Christopher G

    2006-03-01

    Charcot and his medical observations remain an enduring topic of scientific study in neurology, but he is also the topic of modern literary works. This essay examines the depiction of Jean-Martin Charcot (1825-1893) as a character in late-twentieth-century literature as an index of the contemporary nonmedical literary public's interest in neurology and Charcot. It focuses on three contemporary works that involve Charcot as a central figure with comparison between primary source documents and the rendered context, character development, and plot lines of these literary works. The two French novels [Slumbers of Indiscretion and Dr. Charcot of the Salpêtrière] and one American play [Augustine (Big Hysteria)] approach Charcot and neurology with differing levels of historical accuracy. All create a figure of authority, each with a different coloration of the balance between power and its abuse. Two focus almost exclusively on his work with hysteria and inaccurately amplify Charcot's concern with symbolic sexual conflict as the origin of hysteria and fictionalize more extensive interactions with Freud than historical documents support. The three works demonstrate that Charcot retains an enduring fascination with an enigmatic personality, a controversial career, and a pivotal role in the development of studies involving the brain and behavior. Neurologists should not look to these works as replacements for more seriously composed historical studies, but as enrichments anchored in the imaginative possibilities of Charcot and his fin de siècle era.

  13. Warm & wet or warm & dry? - A tree-ring based drought reconstruction from the European lowlands with emphasis on the medieval climate anomaly

    Recent advances in reconstructing natural drought variability in Europe, such as the 'Old world drought atlas' (Cook et al., 2015), have sharpened our picture of historical hydroclimatic variability. However, our knowledge lacks high spatial resolution, especially for the northern non-arid regions. For example, it is still under debate if the so called medieval climate anomaly (MCA; ~950-1300 AD), a period of warm temperatures comparable to the contemporary warm phase, was likewise accompanied by increased drought occurrence, or, on the contrary, was rather wet (e.g. Kress et al., 2014). Here, we present a new millennial long drought reconstruction based on a unique dataset of tree rings from historical and modern beech wood from the northeastern European lowlands. Beech has a stable and strong regional summer drought signal over the calibration period of instrumental data (r>0.7 with drought index PDSI over 1900-2010) which, in contrast to other species such as oak, is consistent irrespective of the site/soil conditions the trees grew in. It can be assumed that during medieval times beech wood was available locally and not traded long distances. This strongly reduces the possibility that the new reconstruction mixes different signals of the possibly high spatial variability of precipitation. The extremely high replication of our chronology for the period 1000-1300 AD (peak in town foundations in NE-Germany) with more than 600 series enables a direct comparison with the well replicated recent period 1800-2010. In contrast to the results of Kress et al. (2014) for the Swiss Alps, but in accordance with the 'Old world drought atlas', our first results point at a rather dry and warm MCA in NE-Germany. In addition they support the observation that the hydroclimate of the twentieth century was highly variable compared with the last millennium. References Cook ER, Seager R, Kushnir Y, et al.
