Feasibility of new ladle-treated Hadfield steel for mining purposes

NASA Astrophysics Data System (ADS)

El Fawkhry, M. K.

2018-03-01

A debate has arisen over the possibility of using a new ladle-treated Hadfield steel instead of conventional heat-treated Hadfield steel in mining applications. This debate might be solved by identifying the differences between the mechanical properties and strain-hardening properties of conventional heat-treated Hadfield steel and its counterpart ladle-treated Hadfield steel. Tensile and compression tests demonstrated that the ductility of ladle-treated Hadfield steel is similar to that of conventional heat-treated steel. However, the strain-hardening property of the ladle-treated Hadfield steel is almost two times higher than that of the heat-treated Hadfield steel. The results of this study demonstrate that the improvement of the strain-hardening behavior is attributable to the low stacking-fault energy of the main austenite matrix, which results from the high segregation coefficient of carbon and manganese solutes of the main austenite matrix into the new eutectic phase. Superior wear abrasion resistance is a potential consequence of different strain-hardening properties under low and high loads.

Microstructural characteristics of Hadfield steel solidified under high pressure

Samples of Hadfield steel, high manganese austenite steel with 13 wt% manganese and 1.2 wt% carbon, were solidified under a pressure of 6 GPa. The microstructures of the samples were analyzed by metallography and X-ray diffraction. The results indicate that the solidification microstructure of the Hadfield steel was remarkably refined under high pressure. Additionally, the carbide of M23C6 was obtained in the Hadfield steel solidified under high pressure was different from the carbide of M3C obtained by solidification under normal pressure. Furthermore, high pressure promoted the formation of orientational solidified microstructure of the Hadfield steel.

Strain Hardening of Hadfield Manganese Steel

The plastic flow behavior of Hadfield manganese steel in uniaxial tension and compression is shown to be greatly influenced by transformation plasticity phenomena. Changes in the stress-strain (σ-ɛ) curves with temperature correlate with the observed extent of deformation twinning, consistent with a softening effect of twinning as a deformation mechanism and a hardening effect of the twinned microstructure. The combined effects give upward curvature to the σ-ɛ curve over extensive ranges of plastic strain. A higher strain hardening in compression compared with tension appears to be consistent with the observed texture development. The composition dependence of stacking fault energy computed using a thermodynamic model suggests that the Hadfield composition is optimum for a maximum rate of deformation twinning. Comparisons of the Hadfield steel with a Co-33Ni alloy exhibiting similar twinning kinetics, and an Fe-21Ni-lC alloy deforming by slip indicate no unusual strain hardening at low strains where deformation is controlled by slip, but an unusual amount of structural hardening associated with the twin formation in the Hadfield steel. A possible mechanism of anomalous twin hardening is discussed in terms of modified twinning behavior (pseudotwinning) in nonrandom solid solutions.

Ductile-to-Brittle transition in <111> hadfield steel single crystals

NASA Astrophysics Data System (ADS)

Astafurova, E. G.; Chumlyakov, Yu. I.

2010-10-01

The deformation mechanism and the character of fracture of <111> austenitic Hadfield steel single crystals are studied during tension in the temperature range 77-673 K by scanning and transmission electron microscopy. It is found that a change in the fracture mechanism from ductile to brittle fracture according to the fractography criterion takes place at a higher temperature than that determined from a change in the elongation to failure of the single crystals. The ductile-to-brittle transition in the Hadfield steel single crystals is shown to be related to a high level of deforming stresses induced by solid-solution hardening and to mechanical twinning.

The paper is devoted to deformation relief formed on the surface of Hadfield steel while scratching under a linearly increasing load. The deformation relief is analyzed to detect regions with microfracture of the surface layer of Hadfield steel. Crack generation regions coincide with regions of the most intense acoustic emission (AE) signal. Single and multiple slip bands are observed in various grains of the material. As the load increases, slip bands thicken and grains with multiple slip are more frequent.

Mechanism of work hardening in Hadfield manganese steel

NASA Astrophysics Data System (ADS)

Dastur, Y. N.; Leslie, W. C.

1981-05-01

When Hadfield manganese steel in the single-phase austenitic condition was strained in tension, in the temperature range - 25 to 300 °C, it exhibited jerky (serrated) flow, a negative (inverse) strain-rate dependence of flow stress and high work hardening, characteristic of dynamic strain aging. The strain rate-temperature regime of jerky flow was determined and the apparent activation energies for the appearance and disappearance of serrations were found to be 104 kJ/mol and 146 kJ/mol, respectively. The high work hardening cannot be a result of mechanical twinning because at -50 °C numerous twins were produced, but the work hardening was low and no twins were formed above 225 °C even though work hardening was high. The work hardening decreased above 300 °C because of the cessation of dynamic strain aging and increased again above 400 °C because of precipitation of carbides. An apparent activation energy of 138 kJ/mol was measured for static strain aging between 300 and 400 °C, corresponding closely to the activation energies for the disapperance of serrations and for the volume diffusion of carbon in Hadfield steel. Evidence from the present study, together with the known effect of manganese on the activity of carbon in austenite and previous internal friction studies of high-manganese steels, lead to the conclusion that dynamic strain aging, brought about by the reorientation of carbon members of C-Mn couples in the cores of dislocations, is the principal cause of rapid work hardening in Hadfield steel.

A detailed investigation of the strain hardening response of aluminum alloyed Hadfield steel

NASA Astrophysics Data System (ADS)

Canadinc, Demircan

The unusual strain hardening response exhibited by Hadfield steel single and polycrystals under tensile loading was investigated. Hadfield steel, which deforms plastically through the competing mechanisms slip and twinning, was alloyed with aluminum in order to suppress twinning and study the role of slip only. To avoid complications due to a grained structure, only single crystals of the aluminum alloyed Hadfield steel were considered at the initial stage of the current study. As a result of alloying with aluminum, twinning was suppressed; however a significant increase in the strain hardening response was also present. A detailed microstructural analysis showed the presence of high-density dislocation walls that evolve in volume fraction due to plastic deformation and interaction with slip systems. The very high strain hardening rates exhibited by the aluminum alloyed Hadfield steel single crystals was attributed to the blockage of glide dislocations by the high-density dislocation walls. A crystal plasticity model was proposed, that accounts for the volume fraction evolution and rotation of the dense dislocation walls, as well as their interaction with the active slip systems. The novelty of the model lies in the simplicity of the constitutive equations that define the strain hardening, and the fact that it is based on experimental data regarding the microstructure. The success of the model was tested by its application to different crystallographic orientations, and finally the polycrystals of the aluminum alloyed Hadfield steel. Meanwhile, the capability of the model to predict texture was also observed through the rotation of the loading axis in single crystals. The ability of the model to capture the polycrystalline deformation response provides a venue for its utilization in other alloys that exhibit dislocation sheet structures.

The competing effects of slip and twinning on the deformation of Hadfield manganese steel single and polycrystals

Hadfield steel is well known for its high strain hardening. However, the mechanism of high strain hardening is still not completely understood. There is a striking paucity of single crystal studies that would allow a superior understanding of the fundamental deformation mechanisms by circumventing the complications associated with grain boundaries. With this need, the present study is aimed at studying Hadfield steel in single and polycrystalline forms. For this purpose, the stress-strain behavior of Hadfield steel (Fe, 12.3% Mn, 1.0 C, in wt.%) single crystals studied for selected orientations ([001], [1¯11], [1¯23], [1¯44] and [1¯5 10]), and for different interstitial contents under tension and compression in the temperature range of 113 K to 293 K. The effect of twinning, slip and stacking faults was revealed in terms of the critical stress levels, and the strain-hardening coefficients. Based on the experimental observations, a model is presented that predicts the orientation, stress direction and solid solution content effects on the critical stress for initiating twinning. Nitrogen was also added to Hadfield steel. Nitrogen was not only proven to be a more effective strengthening agent than carbon in Hadfield steel but also it served as a better trigger for twinning. Stress-strain responses of Hadfield steel were modeled using a viscoplastic self consistent approach. A unique hardening formulation was proposed in the constitutive model incorporating length scales associated with spacing between twin lamellae and grain boundaries. The responses of single crystals and polycrystals with different grain sizes were captured closely with the model. Based on simulations, it was possible to explain unequivocally the upward curvature in stress-strain curves of Hadfield steel. A similar study on the 316L stainless steel single crystals indicated that the addition of nitrogen lead austenitic stainless steel to exhibit deformation mechanisms, orientation and

A Conversion Electron Mössbauer Spectroscopy, (CEMS), study of phase transformations in a Hadfield steel induced by high rate strains is reported. Hadfield steel samples were impact deformed and the ensuing changes in the magnetic properties at the deformed zone and its surroundings have been studied by CEMS. The CEMS results are compared with wear tests and optical microscopy and show a formation of martensite by impact deformation only at the surface. Martensite is not produced by compression or tensile stresses but appears after wear tests in proportions that depend on the load and velocity conditions of test. The understanding of martensite phase formation and its evolution during deformation processes is also addressed.

Materials Informatics concept using computational intelligence based approaches are employed to bring out the significant alloying additions to achieve grain refinement in cast Hadfield steel. Castings of Hadfield steels used for railway crossings, requires fine grained austenitic structure. Maintaining proper grain size of this component is very crucial in order to achieve the desired properties and service life. This work studies the important variables affecting the grain size of such steels which includes the compositional and processing variables. The computational findings and prior knowledge is used to design the alloy, which is subjected to a few trials to validate the findings.

In this study, Fe-12.50Mn-1.10C-1.70Cr-0.40Mo-0.40Si-0.50(max)P-0.50(max)S (Hadfield alloy) and Fe-28.4Mn-0.86C-1.63Al-0.42Cu-1.80Mo-1.59Si-0.60W (Fermanal alloy) (Wt. %) in the aged condition were compared in terms of its tribological and microstructural properties. The x-ray diffraction (XRD) patterns were refined with the lines of the austenitic γ-phase, Chromium Iron Carbide (Cr2Fe14C), Iron Carbide (Fe2C), and Iron Oxide (Fe0.974O (II)) for the Hadfield alloy, and the lines of the austenitic γ-phase, martensite (M), Mn1.1Al0.9 phase and iron carbide (Fe7C3) for the Fermanal alloy. Mössbauer spectra were fit with two sites for the Hadfield alloy, which displayed as a broad singlet because of the austenitic disordered phase, and had a magnetic hyperfine field distribution, which corresponds to the Cr2Fe14C ferromagnetic carbides found by XRD. There were two paramagnetic sites, a singlet, which corresponds to the austenite disordered phase, and a doublet, which can be attributed to the Fe7C3 carbide. The obtained Rockwell C hardness for aged Hadfield and Fermanal alloys were 43.786 and 50.018 HRc, respectively.

The effect of aluminum on the work hardening and wear resistance of hadfield manganese steel

NASA Astrophysics Data System (ADS)

Zuidema, B. K.; Subramanyam, D. K.; Leslie, W. C.

1987-09-01

A study has been made of the work-hardening and wear resistance of aluminum-modified Hadfield manganese steels ranging in composition from 1.00 to 1.75 Pct carbon and from 0.0 to 4.0 Pct aluminum. Aluminum additions reduced carbon activity and diffusivity in austenites of Hadfield’s composition, increasing the metastable solubility of carbon in Hadfield steel. Aluminum additions inhibited mechanical twinning and, by inference, increased the stacking fault energy of austenite. Increasing carbon in solution in austenite expanded the temperature range over which dynamic strain aging and rapid work hardening occurred. Simultaneous aluminum additions and increased carbon content increased the work-hardening rate and high-stress abrasion resistance of Hadfield steel, but there was an optimum aluminum content beyond which both declined. Maximum work-hardening rate was exhibited by an alloy containing nominally 1.75 Pct C, 13.5 Pct Mn, and 1.3 Pct Al. Improved high-stress abrasion resistance was also found in an alloy containing nominally 1.00 Pct C, 13.5 Pct Mn, and 4.0 Pct Al.

Deformation relief evolution during sliding friction of Hadfield steel single crystal

NASA Astrophysics Data System (ADS)

Lychagin, D. V.; Filippov, A. V.; Novitskaya, O. S.; Kolubaev, A. V.; Sizova, O. V.

2017-12-01

The paper deals with the evolution of the deformation relief formed on lateral faces of single crystals of Hadfield steel during dry sliding friction. The use of single crystals with the predetermined orientation enables to analyze the development of shear systems subject to the duration of tribological tests. As the test duration increases, slip bands are curved and thicken in the near-surface region. After 24 hours of friction, single crystals of Hadfield steel demonstrate the maximum hardening. Afterwards, the wear process begins, which is followed by the repeated strain hardening of the specimens. After 48 hours of friction, the height of the deformation relief nearly halves on all of the three faces, as compared to that observed after 24 hours of friction. Differences in the propagation height of slip bands on the faces occur due to the uneven running-in as well as the complex involvement pattern of shear systems into the deformation process.

Structural and phase transformations in Hadfield steel upon frictional loading in liquid nitrogen

NASA Astrophysics Data System (ADS)

Korshunov, L. G.; Sagaradze, V. V.; Chernenko, N. L.

2016-08-01

Structural transformations that occur in 110G13 steel (Hadfield) upon sliding friction in liquid nitrogen (-196°C) have been investigated by metallographic, electron-microscopic, and X-ray diffraction methods. The frictional action was performed through the reciprocating sliding of a cylindrical indenter of quenched 110G13 steel over a plate of the studied steel. A like friction pair was immersed into a bath with liquid nitrogen. It has been shown that the Hadfield steel quenched from 1100°C under the given temperature conditions of frictional loading retains the austenitic structure completely. The frictional action forms in a surface layer up to 10 μm thick the nanocrystalline structure with austenite grains 10-50 nm in size and a hardness 6 GPa. Upon subsequent low-temperature friction, the tempering of steel at 400°C (3 h) and at 600°C (5 min and 5 h) brings about the formation of a large amount (tens of vol %) of ɛ (hcp) martensite in steel. The formation of this phase under friction is supposedly a consequence of the reduction in the stacking fault energy of Hadfield steel, which is achieved due to the combined action of the following factors: low-temperature cooling, a decrease in the carbon content in the austenite upon tempering, and the presence of high compressive stresses in the friction-contact zone.

The methods of transmission electron microscopy (TEM) and electron diffraction are used to study the carbides precipitated in Hadfield steel Mn13 during 2-h aging at 475°C. It is shown that carbides of types (Fe, Mn, Cr)23C6 and mixed (Fe, Mn, Cr)7C3 + (Fe, Mn, Cr)3C precipitate simultaneously over austenite grain boundaries. The data on precipitation of M23C- and M7C3-type carbides in a Hadfield steel after water quenching and aging are pioneer ones. Strict orientation relations of the M23C6 carbides and of the austenite matrix are determined.

The influence of severe plastic deformation by high pressure torsion on structure and mechanical properties of Hadfield steel single crystals

NASA Astrophysics Data System (ADS)

Zakharova, G. G.; Astafurova, E. G.

2010-07-01

Hadfield steel single crystals have been deformed by high pressure torsion at room temperature (P=5GPa) for 1, 2, 3 revolutions. The resulting microstructure has been studied by means of transmission electron microscopy (TEM) and X-ray analysis. The size of fragments decreases with increasing number of revolutions due to interaction of slip dislocations, microbands and thin twins. As a result of severe plastic deformation, the microhardness of the Hadfield steel has been increased, and a portion of epsilon, α' martensite has been found.

2018-03-01

An austenitic Hadfield steel was roll-bonded with a 1.8-GPa-strength-grade martensitic hot-press-forming (HPF) steel to fabricate a multi-layer steel (MLS) sheet. Near the Hadfield/HPF interface, the carburized and decarburized layers were formed by the carbon diffusion from the Hadfield (1.2%C) to HPF (0.35%C) layers, and could be regarded as kinds of very thin multi-layers of 35 μm in thickness. The tensile test and fractographic data indicated that the MLS sheet was fractured abruptly within the elastic range by the intergranular fracture occurred in the carburized layer. This was because C was mainly segregated at prior austenite grain boundaries in the carburized layer, which weakened grain boundaries to induce the intergranular fracture. In order to solve the intergranular facture problem, the MLS sheet was tempered at 200 °C. The stress-strain curve of the tempered MLS sheet lay between those of the HPF and Hadfield sheets, and a rule of mixtures was roughly satisfied. Tensile properties of the MLS sheet were dramatically improved after the tempering, and the intergranular fracture was erased completely. In particular, the yield strength up to 1073 MPa along with the high strain hardening and excellent ductility of 32.4% were outstanding because the yield strength over 1 GPa was hardly achieved in conventional austenitic steels.

The results of experimental research into dry sliding friction of Hadfield steel single crystals involving registration of acoustic emission are presented in the paper. The images of friction surfaces of Hadfield steel single crystals and wear grooves of the counterbody surface made after completion of three serial experiments conducted under similar conditions and friction regimes are given. The relation of the acoustic emission waveform envelope to the changing friction factor is revealed. Amplitude-frequency characteristics of acoustic emission signal frames are determined on the base of Fast Fourier Transform and Short Time Fourier Transform during the run-in stage of tribounits and in the process of stable friction.

Microstructure in Worn Surface of Hadfield Steel Crossing

NASA Astrophysics Data System (ADS)

Zhang, F. C.; Lv, B.; Wang, T. S.; Zheng, C. L.; Li, M.; Zhang, M.

In this paper a failed Hadfield (high manganese austenite) steel crossing used in railway system was studied. The microstructure in the worn surfaces of the crossing was investigated using optical microscopy, scanning electron microscopy, transmission electron microscopy and Mössbauer spectroscopy. The results indicated that a nanocrystallization layer formed on the surface of the crossing served. The formation mechanism of the nanocrystalline is the discontinuous dynamic recrystallization. The energy for the recrystallization nucleus formation originates from the interactions between the twins, the dislocations, as well as twin and dislocation. High-density vacancies promoted the recrystallization process including the dislocation climb and the atom diffusion.

Friction-induced structural transformations of the carbide phase in Hadfield steel

2015-08-01

Structural transformations of the carbide phase in Hadfield steel (110G13) that occur upon plastic deformation by dry sliding friction have been studied by methods of optical metallography, X-ray diffraction, and transmission electron microscopy. Deformation is shown to lead to the refinement of the particles of the carbide phase (Fe, Mn)3C to a nanosized level. The effect of the deformation-induced dissolution of (Fe, Mn)3C carbides in austenite of 110G13 (Hadfield) steel has been revealed, which manifests in the appearance of new lines belonging to austenite with an unusually large lattice parameter ( a = 0.3660-0.3680 nm) in the X-ray diffraction patterns of steel tempered to obtain a fine-lamellar carbide phase after deformation. This austenite is the result of the deformation-induced dissolution of disperse (Fe, Mn)3C particles, which leads to the local enrichment of austenite with carbon and manganese. The tempering that leads to the formation of carbide particles in 110G13 steel exerts a negative influence on the strain hardening of the steel, despite the increase in the hardness of steel upon tempering and the development of the processes of the deformation-induced dissolution of the carbide phase, which leads to the strengthening of the γ solid solution.

2004-06-01

On single crystals of Hadfield steel (Fe-13Mn-1.3C, Fe-13Mn-2.7Al-1.3C, wt.%) the systematical investigations of deformation mechanisms - slip and twinning, stages of plastic flow, strain hardening coefficient depending on orientation of tensile axis have been carried out by methods of optical and electron microscopy, x-ray analysis. Is has been shown that the combination of low stacking fault energy (γ{SF}=0.03J/m^2) with high concentration of carbon atoms in aluminium-free steel results in development of the mechanical twinning at room temperature in all crystal orientations. The new type of twinning with formation of extrinsic stacking fault has been found out in [001] single crystals. Experimentally it has been established that alloying with aluminium leads to increase of stacking fault energy of Hadfield steel and suppresses twinning in all orientations of crystals at preservation of high values of strain-hardening coefficients θ.

Thus, this method has great potential for astronaut health monitoring during future long-term space flights and it also has important implications for testing of individuals on Earth, especially the elderly, who are at risk for fainting. The research will also allow demonstrating the feasibility of obtaining a set of indicators of overall cardiovascular regulation from the non-invasive measurement of continuous blood pressure.

Optimal conditions to increase life time of casting parts have been investigated by applying various cycles of heat treatment and shot peening on Hadfield steel surface. Metallographic and SEM microstructure examinations were used to determine the effects of shot peen, austenitizing time and temperature simultaneously. The results showed that with increasing austenitizing time and temperature of casting sample, carbides resolved in austenite phase and by further increase of austenitizing temperature and time, the austenite grain size becomes larger. Metallographic images illustrated that shot peening on Hadfield steel surface; Austenite - Martensite transformation has not occurred, but its matrix hardened through twining formation process.

This work proposes to analyze the behavior of austenitic manganese - Hadfield steel during laser beam welding in continuous regime. In order to limit the number of experiments, a 2 4 type factorial experiment was used, with 16 assays, after a frequently used program matrix for these situations. Fusion lines at different service regimes, as well as head to head welds were performed. Microhardness measurements and microstructure modifications that appear as an effect of laser irradiation are also analyzed.

Strain localization in <111> single crystals of Hadfield steel under compressive load

NASA Astrophysics Data System (ADS)

Astafurova, E. G.; Zakharova, G. G.; Melnikov, E. V.

2010-07-01

A study of strain localization under compression of <111> Hadfield steel single crystals at room temperature was done by light and transmission electron microscopy. At epsilon<1%, macro shear bands (MSB) form that have non-crystallographic and complex non-linear habit planes and are the results of the interaction of dislocation slip on conjugate slip planes. Mechanical twinning was experimentally found inside the MSB. After the stage of MSBs formation, deformation develops with high strain hardening coefficient and corresponds to interaction of slip and twinning inside as well as outside the MSBs.

Two modified X120Mn12 Hadfield steels, differing in the amount of the alloying elements Al and N, are analyzed with respect to AlN precipitation and its effects on ductility. Charpy impact tests are performed, demonstrating the loss of ductility in the one grade containing a high density of AlN precipitates. The characterization of the precipitates is carried out by high-resolution scanning electron microscopy (HRSEM). Depending on chemical composition, primary and secondary AlN precipitates are detected on prior austenite grain boundaries and within the bulk volume. The experimental observations are confirmed by thermokinetic simulations, using the software package MatCalc (Vienna University of Technology, Vienna, Austria).

Effects of laser-shock processing on the microstructure and surface mechanical properties of hadfield manganese steel

NASA Astrophysics Data System (ADS)

Chu, J. P.; Rigsbee, J. M.; Banaś, G.; Lawrence, F. V.; Elsayed-Ali, H. E.

1995-06-01

The effects of laser-shock processing (LSP) on the microstructure, hardness, and residual stress of Hadfield manganese (1 pct C and 14 pct Mn) steels were studied. Laser-shock processing was performed using a Nd: glass phosphate laser with 600 ps pulse width and up to 120 J/pulse energy at power density above 1012 W/cm2. The effects of cold rolling and shot peening were also studied for comparison. Laser-shock processing caused extensive formation of ɛ hexagonal close-packed (hep) martensite (35 vol pct), producing up to a 130 pct increase of surface hardness. The surface hardness increase was 40 to 60 pct for the shot-peened specimen and about 60 pct for the cold-rolled specimen. The LSP strengthening effect on Hadfield steel was attributed to the combined effects of the partial dislocation/stacking fault arrays and the grain refinement due to the presence of the ɛ-hcp martensite. For the cold-rolled and shot-peened specimens, the strengthening was a result of ɛ-hcp martensite and twins with dislocation effects, respectively. Shot peening resulted in a relatively higher compressive residual stress throughout the specimen than LSP.

[Healing and the Roman imperial culture].

PubMed

Ziethen, G

1994-01-01

From the time of Augustus till Late Antiquity one of the important elements of Roman Imperial policy was the celebration of rituals honouring the Roman Emperor. Elements of Hellenistic ruler cult and traditions of the Roman Republican Age were connected with Roman administration, the economic life and military organisation. Thereby the Roman Emperor generally was considered not only as a powerful and legitimate political leader but also as a well-educated and informed princeps with some kind of ritual sphere. Continuing the traditions of kingship risen in the Oriental monarchies and traduced to the Hellenistic rulers, the Roman Emperor seemed--pictured as Asclepius or Sarapis--to be able to heal not only incurable persons by magic therapy, but also to give a cure to mishandled affairs of state. The hope of the people in the panacea founded on the Emperor's knowledge was explained differently on two intellectual levels: the belief in magical-medical practices against threatening demons and the sophisticated comparisons of the eras of the Roman Empire expressed as the progress of human life from the cradle of iuventus to the old age of senectus. With the image of the Roman State as a human being a tradition began which had been prepared by the parable of the body and the limbs since early Roman historiography. From paganism to the Christianisation of the Roman Empire the vocabulary of healing and therapy was used in papyrological, literary, juridical and theological texts expressing the expectation in impersonation and ceremony of the Roman and Byzantine Emperors till the godblessed monarchs in Christian Europe.

The role of aluminum alloying on strength properties and deformation mechanisms (slip, twinning) of <123> single crystals of Hadfield steel under tensile loading at T = 300 K is demonstrated. It is found out that aluminum alloying suppresses twinning deformation in the <123> single crystals and, during slip, results in a dislocation structure change from a uniform dislocation distribution to a planar dislocation structure.

The Romans and ritual murder.

PubMed

Schultz, Celia E

2010-01-01

The Roman abhorrence of human sacrifice presented by ancient literary sources stands in contrast to the frequency of rites requiring the death of a human being performed by the Romans during the Republic (509-44 BCE). After examining the ways our sources talk about ritual murder, especially as it was practiced by foreign peoples and subversive or tyrannical elements within Roman society, this discussion turns to the issue of the forms of ritual murder performed by the Romans. Of these various rites, the only one clearly identified by them as human sacrifice, that is, as an offering to the gods of a human life, is the live interment of Gauls and Greeks. Other forms of ritual murder-the burial of unchaste Vestal Virgins and the drowning of hermaphroditic children-were not, in Roman opinion, sacrifice. This distinction made the disposal of Vestal Virgins and hermaphrodites acceptable.

The effect of hydrogenation on the strain-hardening behavior and the deformation mechanisms of <113>-oriented single crystals of Hadfield steel was investigated under tension at room temperature. The stages of plastic flow and deformation mechanisms for hydrogen-charged specimens are similar to one in hydrogen-free state: slip → slip + single twinning → slip + multiple twinning. Hydrogen alloying favors to mechanical twinning, micro- and macrolocalization of plastic flow.

The Bauschinger effect (BE) in single crystals of Hadfield manganese steel (Fe, 12.3 Mn, 1.0C in wt pct) was studied for three crystallographic orientations, [overline 1 11],{text{ [}}overline {text{1}} 23], and [001]. Both forward tensionreverse compression (FT/RC) and forward compression-reverse tension (FC/RT) loading schemes were used to investigate the role of deformation history on the BE. The evolution of stress-strain response and a dimensionless Bauschinger parameter were used to study the BE. The BE stems from long-range back stress generated by the dislocation pileups, at the twin and localized slip boundaries. Twinning boundaries present a strong obstacle and lead to a strong BE If localized slip followed twinning, permanent softening was evident, such as in the case of the [overline 1 11] FT/RC scheme. Localized slip and multiple slip in the forward loading provided a transient effect in the stress-strain response without a significant permanent softening. Hadfield steel single crystals have demonstrated a high BE for orientations conducive to combined twinning/slip deformation. The BE increased with increasing prestrain, then saturated and started to decrease, in contrast with precipitation-hardened alloys. A unique strain-hardening approach along with the back stress calculation was introduced into a viscoplastic self-consistent (VPSC) formulation. The strain-hardening formulation incorporates length scales associated with spacing between twin lamellae. The simulations correctly predicted the BE and the stress-strain response for both forward and reverse loading.

The Romans were perhaps the most impressive exponents of water resource management in pre-industrial times with irrigation and virtual water trade facilitating unprecedented urbanisation and socio-economic stability for hundreds of years in a region of highly variable climate. To understand Roman water resource management in response to urbanisation and climate variability, a Virtual Water Network of the Roman World was developed. Using this network we found that irrigation and virtual water trade increased Roman resilience to inter-annual climate variability. However, urbanisation and population growth arising from virtual water trade likely pushed the Empire closer to the boundary of its water resources, led to an increase in import costs, and eroded its resilience to climate variability in the long term. Our newest findings also assess the impact that persistent climate change associated with Holocene climate anomalies had on Roman water resource management. Specifically we assess the impact of the change in climate from the Roman Warm Period to the Dark Ages Cold Period on the Roman food supply and whether it could have contributed to the fall of the Western Roman Empire.

The results of metallographic, chemical and mechanical analysis of two Roman axes are presented. Insights into the technologies used by the Romans are considered. These axes were buried in a Roman village in La Olmeda, Palencia, Spain, which was built around the first century BC and it was later abandoned and destroyed in the fifth century AD. It has been observed that some artefacts, specifically axes show that the technology existed to increase hardness by solid-state welding of sheet steel of different carbon contents.

Proton irradiated Hadfield steel foil was studied using transmission Mössbauer spectroscopy with high velocity resolution and conversion electron Mössbauer spectroscopy. It was shown that proton irradiation leads to structural changes in the foil as well as to surface oxidation with ferric hydrous oxide formation (ferrihydrite). Moreover, oxidation on the foil underside was higher than on the foil right side.

The Romans were masters of water resource management. They employed sophisticated irrigation techniques alongside a highly integrated food redistribution system that provided stable food supplies under the variable hydroclimatic regime within the Roman World. However, a number of paleoclimate studies have demonstrated hydroclimatic changes during the Roman Period that exceeded the amplitude and persistence of normal climate variability. In particular, there was a shift from warmer and more stable hydroclimatic conditions in the Roman Warm Period (c.250 BC - 250 AD) to cooler and more variable conditions in Late Roman Period (after c.250 AD). In this study we use a socio-hydrological model of the Roman world to explore the impact of hydroclimatic changes between the Roman Warm Period and Late Roman Period on the Roman food production and redistribution system. We calculate crop yields based on temperature and water resource availability using PC Raster Global Water Balance model (PCR-GLOBWB). PCR-GLOBWB is forced with reanalysis climate fields reflecting reconstructions of Roman Warm Period to the Late Roman climate patterns. Cropland areas and settlement patterns are derived from a database of 14,700 Roman settlement sites and crop suitability maps. We simulate food redistribution using a multi-agent food redistribution network with link weights based on Orbis: The Stanford Geospatial Network of the Roman World. Our analysis indicates a reduction in crop yields during the Late Roman Period compared with the Roman Warm Period owing to cooler temperatures. In addition, our simulations indicate that increased hydroclimatic variability decreased the stability of yields in the Late Roman period. Crop yields in the Western Empire are simulated to have been impacted most by the change in climate owing to cooler average temperatures and greater hydroclimatic variability compared with the Eastern part of the Empire. The food redistribution network was essential to buffer

Roman seals associated with collyria (Latin expression for eye drops/washes and lotions for eye maintenance) provide valuable information about eye care in the antiquity. These small, usually stone-made pieces bore engravings with the names of eye doctors and also the collyria used to treat an eye disease. The collyria seals have been found all over the Roman empire and Celtic territories in particular and were usually associated with military camps. In Hispania (Iberian Peninsula), only three collyria seals have been found. These findings speak about eye care in this ancient Roman province as well as about of the life of the time. This article takes a look at the utility and social significance of the collyria seals and seeks to give an insight in the ophthalmological practice of in the Roman Empire.

Structural features and mechanical properties of austenitic Hadfield steel after high-pressure torsion and subsequent high-temperature annealing

Mechanisms of structure fragmentation and strengthening of single crystals of a Hadfield steel after warm torsion under high-pressure torsion (HPT) and subsequent annealing in a temperature range of 400-800°C have been studied. Multiple twinning and formation of ultrafine carbides upon HPT at 400°C ( P = 5 GPa) promote rapid fragmentation of the microstructure. They are responsible for the high mechanical properties of the steel after HPT and the thermal stability of the microstructure up to an annealing temperature of 500°C.

A growing number of paleodiet investigations over recent years have begun to reveal the stark dietary differences that existed between regions of the Roman Empire, as well as significant changes in subsistence strategies after its fall. The present study explores the dietary changes at the Roman to post-Roman (Germanic) transition in the Northwest Iberian Peninsula, in order to improve our understanding of the changes that occurred at end of the Roman Empire in different regions across Europe and to also consider the influence of climate had on them. The carbon and nitrogen stable isotope investigation in bone collagen from A Lanzada, NW Spain (100-700 AD), which was an important commercial, coastal settlement has been presented. A human sample of 59 individuals, 6 of them subadults, is compared with 31 faunal specimens, which include a number of marine fish. Isotope data for the terrestrial fauna reveal the influence of the sea on the local isotope baseline. Analysis of the human samples indicates a mixed marine-terrestrial diet. A shift in mean human δ(13) C values from -16.7‰ to -14.3‰ provides clear evidence for a significant change in diet in the post-Roman period, probably through the intensification of both marine resources exploitation and C4 -plant consumption (presumably millet). A deterioration of paleoenvironmental conditions, together with a poor socioeconomic situation and the arrival of new people, the Sueves, who brought a new political and socioeconomic system have been discussed as the main causes for the dietary modification in post-Roman times. © 2016 Wiley Periodicals, Inc.

Medicine in Balkans during the Roman Period

The aim of this study is to investigate the archaeological finds to enlighten the medical methods of treatments and operations applied in Balkans during Roman Period. Some independent local and regional find groups, taken from existing publications will be grouped together and a holistic point-of-view will be taken against medicine in Balkan Geography during Roman Period. Due to basic differences it contained, the data before Roman Period are excluded. Most of Greece and Aegean Islands are also excluded since the topic selected is “Medicine of Roman Period.” Greece and Aegean Islands should be evaluated in another study in connection with West Anatolia which is closer than the Balkan Geography in terms of social relations. The spread of medical tools in Balkans during Roman Period is concentrated around military garrisons, and in settlements built around military pathways, and in settlements containing an amphitheater associated with gladiators. This spread is verified by the studies on Bulgaria in general. The data is also compatible with the assertion suggesting that the amount of application of pharmaceutical treatment increases when one moves away from the military centres. PMID:28552838

2017-12-01

Friction is a complex dynamic process. Direct observation of processes occurring in the friction zone is impossible due to a small size of a real contact area and, as a consequence, requires various additional methods applicable to monitor a tribological contact state. One of such methods consists in the analysis of acoustic emission data of a tribological contact. The use of acoustic emission entails the problem of interpreting physical sources of signals. In this paper, we analyze the evolution of acoustic emission signal frames in friction of Hadfield steel single crystals. The chosen crystallographic orientation of single crystals enables to identify four stages related to friction development as well as acoustic emission signals inherent in these stages. Acoustic emission signal parameters are studied in more detail by the short-time Fourier transform used to determine the time variation of the median frequency and its power spectrum. The results obtained will facilitate the development of a more precise method to monitor the tribological contact based on the acoustic emission method.

2008-02-01

The structure of the Hadfield steel (H13) surface layer forming under dry friction is examined. The deformation of the material under the friction surface is studied at a low slip velocity and a low pressure (much smaller than the yields stress of H13 steel). The phase composition and defect substructure on the friction surface are studied using scanning, optical, and diffraction electron microscopy methods. It is shown that a thin highly deformed nanocrystalline layer arises near the friction surface that transforms into a polycrystalline layer containing deformation twins and dislocations. The nanocrystalline structure and the presence of oxides in the surface layer and friction zone indicate a high temperature and high plastic strains responsible for the formation of the layer. It is suggested that the deformation of the material observed far from the surface is due to elastic wave generation at friction.

Comparative studies of regularities in plastic deformation and fracture of the Hadfield polycrystalline steel upon quasi-static tension, impact failure, and shock-wave loading with rear spall are performed. The SINUS-7 accelerator was used as a shock-wave generator. The electron beam parameters of the accelerator were the following: maximum electron energy was 1.35 MeV, pulse duration at half-maximum was 45 ns, maximum energy density on a target was 3.4·1010 W/cm2, shock-wave amplitude was ~20 GPa, and strain rate was ~106 s-1. It is established that the failure mechanism changes from ductile transgranular to mixed ductile-brittle intergranular one when going from quasi-static tensile and Charpy impact tests to shock-wave loading. It is demonstrated that a reason for the intergranular spallation is the strain localization near the grain boundaries containing a carbide interlayer.

Roman mystery iron blades from Serbia

DOE Office of Scientific and Technical Information (OSTI.GOV)

Balos, Sebastian; Benscoter, Arlan; Pense, Alan

A First to Forth Century Roman spear blade from Serbia was found to have an unusual microstructure inconsistent with typical Roman Period iron. An analysis of the blade undertaken at Lehigh University in the US and at the Faculty of Technical Sciences in Novi Sad, Serbia established that it was metallic in appearance, magnetic and had an external layer of red rust. But as metallographically polished, it appeared to contain multiple internal phases and internal cracking. Even after aggressive etching, no typical low carbon microstructure was developed. Scanning electron microscopy, classical and energy dispersive X-ray analysis indicated that the specimenmore » was essentially iron, although its microhardness was too high for typical Roman iron. It was then dubbed 'Mystery Iron.' Analysis of all the data led to the proposal that it was essentially a Roman iron 'fossil' in which the iron had been converted to high temperature iron oxide while retaining the form of the blade, conversion probably occurring in a fire. Subsequent X-ray diffraction analysis confirmed that the blade consisted of FeO and Fe{sub 3}O{sub 4} and the mystery of the iron fossil was at least partially solved. A hypothesis is proposed regarding a potential cause for the fire.« less

Thould, A K; Thould, B T

The pattern of arthritis in Roman Britain was investigated by examining the skeletons of 416 adults from the Roman cemetery at Poundbury Camp near Dorchester, Dorset. The mean height of the people was not much less than that of the current British population, and the prevalence of right handedness was similar to our own. There was a high prevalence of osteoarthritis for such a relatively young community, with particularly severe changes in the vertebral column. The pattern of joints affected by osteoarthritis was different from that seen now, but the prevalence of vertebral ankylosing hyperostosis was much the same. Rheumatoid arthritis was seen as often as the expected rat would indicate, given that the population died young, but it was rare. Other forms of arthritis, including gout and ankylosing spondylitis, were not seen.

Analytical Plan for Roman Glasses

DOE Office of Scientific and Technical Information (OSTI.GOV)

Strachan, Denis M.; Buck, Edgar C.; Mueller, Karl T.

Roman glasses that have been in the sea or underground for about 1800 years can serve as the independent “experiment” that is needed for validation of codes and models that are used in performance assessment. Two sets of Roman-era glasses have been obtained for this purpose. One set comes from the sunken vessel the Iulia Felix; the second from recently excavated glasses from a Roman villa in Aquileia, Italy. The specimens contain glass artifacts and attached sediment or soil. In the case of the Iulia Felix glasses quite a lot of analytical work has been completed at the University ofmore » Padova, but from an archaeological perspective. The glasses from Aquileia have not been so carefully analyzed, but they are similar to other Roman glasses. Both glass and sediment or soil need to be analyzed and are the subject of this analytical plan. The glasses need to be analyzed with the goal of validating the model used to describe glass dissolution. The sediment and soil need to be analyzed to determine the profile of elements released from the glass. This latter need represents a significant analytical challenge because of the trace quantities that need to be analyzed. Both pieces of information will yield important information useful in the validation of the glass dissolution model and the chemical transport code(s) used to determine the migration of elements once released from the glass. In this plan, we outline the analytical techniques that should be useful in obtaining the needed information and suggest a useful starting point for this analytical effort.« less

The Roman curse tablet, produced in ancient Rome period, is a metal plate that inscribed with curses. In this research, several techniques were used to find out the physical structure and chemical composition of the Roman curse tablet, and testified the hypothesis that whether the tablet is made of pure lead or lead alloy. A sample of Roman Curse Tablet from the Johns Hopkins Archaeological Museum was analyzed using several different characterization techniques to determine the physical structure and chemical composition. The characterization techniques used were including optical microscopy, scanning electron microscopy (SEM), atomic force microscopy (AFM), and differential scanning calorimetry (DSC). Because of the small sample size, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and X-ray fluorescence (XRF) cannot test the sample. Results from optical microscopy and SEM, enlarged images of the sample surface were studied. The result revealed that the sample surface has a rough, non-uniform, and grainy surface. AFM provides three-dimensional topography of the sample surface, studying the sample surface in atomic level. DSC studies the thermal property, which is most likely a lead-alloy, not a pure lead. However, none of these tests indicated anything about the chemical composition. Future work will be required due to the lack of measures finding out its chemical composition. Therefore, from these characterization techniques above, the Roman curse tablet sample is consisted of lead alloy, not pure lead.

Medical practice in Graeco-roman antiquity.

PubMed

Cilliers, L; Retief, F P

2006-05-01

The roots of modern medicine can be traced back to the 5th century BC when Hippocratic rational medicine originated on the Greek islands of Cos and Cnidos. In this study we examine the way in which practitioners conducted their profession in Graeco-Roman times, as well as their training. Medical training was by way of apprenticeship with recognized doctors, but no qualifying examinations existed and the standard of practice thus varied enormously. Even in the Roman era the vast majority of medical doctors were Greek and in private practice as itinerant physicians. Civic doctors in the paid service of local communities appeared in Greek society from the 5th century BC onwards, but much later in Rome - probably as late as the 4th century AD. Rome's unique contributions to medicine lay in public health measures (e.g. their aqueducts, public baths and sewages systems) and an excellent medical service for their armies and navy. Hospitals (valetudinaria) were established for military purposes and for slaves on large Roman estates from the 1st century BC, but civic hospitals for the general public originated as late as the 4th century AD. The Greek medical schools of Cos and Cnidos were eventually superseded by the school of Alexandria in Egypt and towards the end of the Roman Empire by that of Carthage in northern Africa. Its gradual demise in the Christian era lowered the curtain on original medical endeavours during antiquity.

Virtual water management in the Roman world

Climate change can have extreme societal impacts particularly in regions that are water-limited for agriculture. A society's ability to manage its water resources in such environments is critical to its long-term viability. Water management can involve improving agricultural yields through in-situ irrigation or the redistribution of virtual water resources through trade in food. Here, we explore how such water management strategies improve societal resilience by examining virtual water management during the Roman Empire in the water-limited region of the Mediterranean. Climate was prescribed based on previously published reconstructions which show that during the Roman Empire when the Central Mediterranean was wetter, the West and Southeastern Mediterranean became drier and vice-versa. Evidence indicates that these shifts in the climatic seesaw may have occurred relatively rapidly. Using the Global hydrological model PCR GLOBWB and estimates of landcover based on the HYDE dataset we generate potential agricultural yield maps under two extremes of this climatic seesaw. HYDE estimates of population in conjunction with potential yield estimates are used to identify regions of Mediterranean with a yield surplus or deficit. The surplus and deficit regions form nodes on a virtual water redistribution network with transport costs taken from the Stanford Geospatial Network Model of the Roman World (ORBIS). Our demand-driven, virtual water redistribution network allows us to quantitatively explore the importance of water management strategies such as irrigation and food trade for the Romans. By examining virtual water transport cost anomalies between climate scenarios our analysis highlights regions of the Mediterranean that were most vulnerable to climate change during the Roman Period.

The Roman state and genetic pacification.

PubMed

Frost, Peter

2010-07-23

Over the last 10,000 years, the human genome has changed at an accelerating rate. The change seems to reflect adaptations to new social environments, including the rise of the State and its monopoly on violence. State societies punish young men who act violently on their own initiative. In contrast, non-State societies usually reward such behavior with success, including reproductive success. Thus, given the moderate to high heritability of male aggressiveness, the State tends to remove violent predispositions from the gene pool while favoring tendencies toward peacefulness and submission. This perspective is applied here to the Roman state, specifically its long-term effort to pacify the general population. By imperial times, this effort had succeeded so well that the Romans saw themselves as being inherently less violent than the "barbarians" beyond their borders. By creating a pacified and submissive population, the empire also became conducive to the spread of Christianity--a religion of peace and submission. In sum, the Roman state imposed a behavioral change that would over time alter the mix of genotypes, thus facilitating a subsequent ideological change.

Putting Roman Dams in Context: a Virtual Approach

Water resources and management have become a critical global issue. During the half-millennium of its existence, the Roman Empire developed numerous strategies to cope with water management, from large-scale urban aqueduct systems, to industrial-scale water mills designed to cope with feeding growing city populations. Roman engineers encountered, adopted, and adapted indigenous hydraulic systems, and left lasting imprints on the landscape of the Mediterranean and temperate Western Europe by employing a range of water technologies. A recent academic study has enabled the identification of remains of and references to seventy-two dams from the Roman era, constructed in Spain between the 1st and 4th century AD. Such unique heritage, without comparisons in the Mediterranean makes Spain an emblematic case study for the analysis of Roman hydraulic engineering and water management policies. Fifty dams have been located and detailed. The twenty-two outstanding, although identified on the ground, have not been able to be acceptably characterized, due in some cases to their being ruins in a highly degraded state, others due to their being masked by repairs and reconstructions subsequent to the Roman era. A good example of such neglected dams is the buttress dam of Consuegra , in Toledo province (Castilla-La Mancha). Dating to the 3rd - 4th century AD, the Dam of Consuegra, on the basin of the Guadiana, with its over 600 metres length and 4,80 metres height, is a remarkable case of Roman engineering mastery. It had a retaining wall upstream, numerous buttresses and perhaps an embankment downstream, of which no remains are left. The application of 3D digital imaging technique to create a high quality virtual model of such monuments has proved to be successful especially for the study of the technological aspects related its construction. The case study of the Roman dam of Muel (Zaragoza) has shown, in fact, as best practices in digital archaeology can provide an original and

Astronomy in towns? An archaeoastronomical approach to the Roman urbanism

2017-03-01

Although the final definition of Archaeoastronomy is still under debate, what is clear is that this discipline offers a different approach to the knowledge of ancient cultures than traditional archaeology has done so far. Archaeoastronomy considers the sky as an inseparabe part of the environment and thus an element of the transformed landscape with highly symbolic content. In the case of the Roman culture, the great colonizing activity involved continuous spatial transformations and the skyscape should be considered as a piece of the created urbanized spaces. For this reason, a number of fieldwork campaigns were conducted in several Roman cities across different regions of the ancient Roman Empire in order to study the configuration of those landscapes and the possible integration of the sky during the buiding processes. At the present, our group has the largest sample of orientations of Roman settlements so far, and here it is shown the preliminary results of an statistical analysis which may offer new answers to the various still open questions in Roman urbanism, often faced from conservative views.

'Cost in transliteration': the neurocognitive processing of Romanized writing.

PubMed

Rao, Chaitra; Mathur, Avantika; Singh, Nandini C

2013-03-01

Romanized transliteration is widely used in internet communication and global commerce, yet we know little about its behavioural and neural processing. Here, we show that Romanized text imposes a significant neurocognitive load. Readers faced greater difficulty in identifying concrete words written in Romanized transliteration (Romanagari) compared to L1 and L2. Functional neuroimaging revealed that the neural cost of processing transliterations arose from significantly greater recruitment of language (left precentral gyrus, left inferior parietal lobule) and attention networks (left mid-cingulum). Additionally, transliterated text uniquely activated attention and control areas compared to both L1 (cerebellar vermis) and L2 (pre-supplementary motor area/pre-SMA). We attribute the neural effort of reading Romanized transliteration to (i) effortful phonological retrieval from unfamiliar orthographic forms and (ii) conflicting attentional demands imposed by mapping orthographic forms of one language to phonological-semantic representations in another. Finally, significant brain-behaviour correlation suggests that the left mid-cingulum modulates cognitive-linguistic conflict. Copyright © 2013 Elsevier Inc. All rights reserved.

The Gate of Heaven: Revisiting Roman Mithraic Cosmology

NASA Astrophysics Data System (ADS)

Assasi, R.

2016-01-01

The definition and origins of Roman Mithraism remain highly problematic and controversial among modern scholars. The majority of research on Roman Mithraism focuses on interpreting the physical evidence because no considerable written narratives or theology from the religion survive. The most important Mithraic artifact is a repeated bull-slaying scene, which leaves no doubt that this figure conveys the core divine message of the cult. There is also another important Mithraic character that seems to be as important as the bull-slayer. This figure is a lion-headed man entwined by a snake. The author suggests that these figures represent the north ecliptic pole and argues for the importance of this astronomical reference in the Mithraic iconography and mythology. The author also demonstrates the possible relation of his proposed astrological model to the geocentric understanding of the axial precession around the ecliptic pole, where the Roman bull-slaying Mithras could be visualized in the form of a Mithraic constellation. This astrological model also is proposed to be the architectural design concept of Roman Mithraeum. The author also points to the core Christian symbols as possible contemporaneous parallels or derivatives of the Mithraic iconography and theology.

Roman Military Medicine and Croatian Archaeological Perspectives.

PubMed

Cesarik, Marijan; Cesarik, Nikola; Duplančić, Darko; Štrmelj, David

2016-09-01

This article offers a general examination of the sources responsible for understanding Roman military medicine, starting with literal and epigraphical sources all the way to archaeological remains consisting of hospitals, the infrastructure of military garrisons and small medical tools. Given that not one of the literary sources does not directly mention the medical personnel within the various military units, epigraphical discoveries widely represent the main source of our knowledge on the subject. On the other hand, the archaeological exploration of military garrisons offers proof of the medical care of Roman soldiers. If at first it appears that Roman military medicine is perfectly obvious and clear, actually this is not the case as many questions remain to be answered and debated. In all this, Croatia has its own archaeological perspective, where notably, one site stands out, which could hold a key role according to the layout of buildings within the garrison including its hospital.

Climate variability can have extreme impacts on societies in regions that are water-limited for agriculture. A society's ability to manage its water resources in such environments is critical to its long-term viability. Water management can involve improving agricultural yields through in-situ irrigation or redistributing water resources through trade in food. Here, we explore how such water management strategies affected the resilience of the Roman Empire to climate variability in the water-limited region of the Mediterranean. Using the large-scale hydrological model PCR-GLOBWB and estimates of landcover based on the Historical Database of the Global Environment (HYDE) we generate potential agricultural yield maps under variable climate. HYDE maps of population density in conjunction with potential yield estimates are used to develop maps of agricultural surplus and deficit. The surplus and deficit regions are abstracted to nodes on a water redistribution network based on the Stanford Geospatial Network Model of the Roman World (ORBIS). This demand-driven, water redistribution network allows us to quantitatively explore how water management strategies such as irrigation and food trade improved the resilience of the Roman Empire to climate variability.

Diet reconstruction in the Roman era.

The samples from the proximal femora were taken from 12 cementeries from the Roman period. The skeletons date from the 1st-4th centuries A.D. Trace element analysis was used in order to reconstruct the basic diet. The sites that best corresponded to the model of Old Germanic diet described by ancient authors "meat, milk and cheese" were found in the Pruszcz Gdanski East Pomerania region close to the Baltic sea as well as in region Halle (Niemberg) and not far from Donau (Sládkovicovo). This diet is characterized by a large amount of protein and consequently of zinc. In the original Old Germanic region in a time period of more than 1000 years (from 400 B.C. to 700 A.D.) there is the same type of trace elements sources for bones and also the same type of the diet. This possibly distinguishes Germanic soldiers (aboriginal) from others groups in Roman legionary camps. It seems that the Donau River is very important for predicting the type of diet in the Roman period. North of the river animal component prevails south of the river vegetal component prevails. The rich agricultural land along the Donau River and in the Pannonian plains affects social arrangement as well as the structure of bones in Germans and Sarmats in the 2nd-4th centuries. Lead became a civilization element. It appeared in the diet of the Greek and Romans. Contamination varied with different social classes. We have found higher lead concentration in the femurs of the Germans than in those of the Sarmatians. The highest concentration we found was in Pannonian towns (Gorsium, Sopianae) and legionary camps (Straubing, Gerulata). In reference to age, the maxima of the highest lead concentrations in Gerulata II are between 11 and 13 years of age and between 40 and 50 years.

Roman mural green pigment painting fragments from three Roman sites in the north of the Roman province Germania Superior: Koblenz Stadtwald Remstecken (KOSR), Weißenthurm " Am guten Mann" (WEIS) and Mendig Lungenkärchen (MELU), dating from second and third centuries AD were analyzed. The experiments were performed nondestructively using synchrotron-based scanning macro-X-ray fluorescence (SR-MA-XRF), synchrotron-based scanning micro-X-ray fluorescence (SR-μ-XRF), synchrotron-based X-ray diffraction (SR-XRD) and Raman spectroscopy. Correlation between SR-MA-XRF, SR-μ-XRF elemental map distributions and optical images of scanned areas was mainly found for the elements Ca, Fe and K. With XRF, Fe and K were identified correlated with green pigment, but in samples from two sites, Mendig Lungenkärchen and Weißenthurm " Am guten Mann", also Cu was detected in minor concentration. The results of SR-XRD and Raman spectroscopy were limited to one sample from Weißenthurm " Am guten Mann". In this sample, green earth and calcium carbonate were identified by SR-XRD and, additionally, malachite by Raman spectroscopy.

Intelligence as the plasticity of instinct: George J. Romanes and Darwin's earthworms.

PubMed

Morganti, Federico

2011-01-01

In the following article I provide a brief analysis of George J. Romanes' conception of intelligence and its relationship with instincts. Through a careful reading of some key-passages from Mental Evolution in Animals (1883)--Romanes' chief work on the subject--I endeavour to show how the very notion of intelligence was related, in Romanes' thought, to individual adaptation to the environmental novelty. Also, I attempt to clarify in what sense, according to Romanes, this capacity was to be included among the factors of organic evolution. Lastly, I compare Romanes' view with that expressed in Darwin's last book, i.e. The Formation of Vegetable Mould through the Action of Worms (1881). I contend that the two scientists basically shared the same conception of the relationship between instincts and intelligence, which accounted not only for the need of phylogenetic continuity, but also for that of discontinuity due to adaptive divergence.

The article considers how burial evidence might contribute to the undestarnding of gender, i.e. the socio-cultural construction of sexual difference, as a dynamic aspect of identity in a Roman province, with a particular focus on women. This subject has hitherto received limited attention and its potential is too great to explore fduly in a short paper. Given this costraint, the article indicates possibilities and problems rather than to offer definitive conclusions. Its emphasis lies on Roman Britain, but similar questions could be applied to other parts of the Roman world.

High-rate deformation and spall fracture of hadfield steel under action of high-current nanosecond relativistic electron beam

Gnyusov, S. F.; Rotshtein, V. P.; Polevin, S. D.; Kitsanov, S. A.

2010-09-01

Features of the plastic deformation and dynamic spall fracture of Hadfield steel under conditions of shock wave loading at a straining rate of ˜106 s-1 have been studied. The shock load (˜30 GPa, ˜0.2 μs) was produced by pulses of a SINUS-7 electron accelerator, which generated relativistic electron bunches with an electron energy of up to 1.35 MeV, a duration of 45 ns, and a peak power on the target of 3.4 × 1010 W/cm2. It is established that the spalling proceeds via mixed viscous-brittle intergranular fracture, unlike the cases of quasi-static tensile and impact loading, where viscous transgranular fracture is typical. It is shown that the intergranular character of the spall fracture is caused by the localization of plastic deformation at grain boundaries containing precipitated carbide inclusions.

On the acoustics of ancient Greek and Roman theaters.

2008-09-01

The interplay of architecture and acoustics is remarkable in ancient Greek and Roman theaters. Frequently they are nowadays lively performance spaces and the knowledge of the sound field inside them is still an issue of relevant importance. Even if the transition from Greek to Roman theaters can be described with a great architectural detail, a comprehensive and objective approach to the two types of spaces from the acoustical point of view is available at present only as a computer model study [P. Chourmouziadou and J. Kang, "Acoustic evolution of ancient Greek and Roman theaters," Appl. Acoust. 69, re (2007)]. This work addresses the same topic from the experimental point of view, and its aim is to provide a basis to the acoustical evolution from Greek to Roman theater design. First, by means of in situ and scale model measurements, the most important features of the sound field in ancient theaters are clarified and discussed. Then it has been possible to match quantitatively the role of some remarkable architectural design variables with acoustics, and it is seen how this criterion can be used effectively to define different groups of ancient theaters. Finally some more specific wave phenomena are addressed and discussed.

The Roman invasion introduces new alloys and metallurgical practices in Iberian Peninsula. The southwestern end of this region has many evidences of connections with the Roman World, but there are no studies about the manufacture and use of copper-based artefacts during this period. Therefore, a set of about 20 ornaments, tools and small attachments recovered at the Roman sites of Monte Molião and Cidade das Rosas was studied by an analytical approach combining micro-EDXRF, optical microscopy, SEM-EDS and Vickers microhardness testing. The artefact composition shows a good correlation with function, namely pure copper for nails and rivets, low-tin bronze (2-6 wt% Sn) for basic tools, high-tin bronze (14 wt% Sn) for fibulae and high-lead bronze (19 wt% Pb) for a decorated jug handle. The manufacture also depends on function because most artefacts were subjected to thermomechanical processing, except the ornaments that would not benefit from post-casting work. Brass and gunmetal were only present in the site with a later chronology. A metallurgy visibly ruled by economical, aesthetical and technological concerns reinforces the evidences about the total integration of Southwestern Iberian Peninsula in the Roman World, but further studies will be essential to determine the evolution of copper-based alloys in Lusitania under Roman influence.

A First Case of Human Trichuriasis from a Roman Lead Coffin in France

A paleoparasitological study was carried out on 2 lead coffins recovered from the Roman site of Jaunay-Clan (near Poitiers, France). For the first time, this particular type of burial gave positive parasitological results, and eggs of the whipworm Trichuris trichiura were identified in 1 individual. In the present case, thanatomorphose associated with funerary practices may explain the scarcity of the recovered eggs. However, human whipworm has now been observed in 9 individuals dated to the Roman period. The very high frequency of Trichuris sp. eggs in Roman archaeological sites (up to 80%) suggests that fecal peril, hygiene, and waste management were problematic during this period. Finally, due to the fact that very few analyses have been conducted on human bodies dated to the Roman period, more analyses must be performed in the future to provide further information about diseases in the Roman world.

Change in silica sources in Roman and post-Roman glass

NASA Astrophysics Data System (ADS)

Aerts, A.; Velde, B.; Janssens, K.; Dijkman, W.

2003-04-01

Although Roman and post-Empire glasses found in Europe are reputed to have a very constant composition and hence source of components, it appears that some 4-5th century and later specimens show evidence of a different source of silica (sand) component. Zirconium and titanium are the discriminating elements. Data presented here for 278 specimens from 1st to 4th century German and Belgian samples indicate a strongly homogeneous Zr and Ti content; N: number of analyzed samples while 62 samples from Maastricht show low Zr-Ti contents from 1st to 3rd century samples while 4-5th century samples show a strong trend of concomitant Ti and Zr increase. If the high values of Zr-Ti represent a new source of silica (sand) the trend from low to high content suggests that a significant amount of low Zr-Ti glass was recycled to form these glass objects. Similar high Ti content can be seen in analysis results reported for other but not all 4-5th century samples found in northern Europe while earlier productions show typical low Ti contents. Although the fusing agent for these glasses seems to have always been natron (a mineral deposit in the Nile delta) from Hellenistic times to the 9th century, a change in the silica source, indicated by variation of the Ti and Zr content, could very well reflect the results of political instability of the 4-5th century exemplified by the fragmentation of the Roman Empire into two parts.

Paetus, it does not hurt: altruistic suicide in the Greco-Roman world.

van Hooff, Anton

2004-01-01

Emile Durkheim, a student of classical education, studied altruistic suicide through an exploration of ancient culture. He associated the concept to civilizations in which people have not reached a sufficient degree of individuation and held that the Greek and Roman civilizations had already developed and were not strongly integrated, a precondition for frequent altruistic suicide. Yet, studies of Greeks and Romans show ample examples. Loyalty and devotion appear to be especially powerful motives. It is concluded that altruistic suicide had its place inside the Greco-Roman world.

Geoarchaeological research for Roman waterworks in the Rhine-Meuse river delta, the Netherlands

2015-04-01

It is known that Romans in the Low Countries at the northern margin of their empire were practicing diverse systems of water state management to maintain economic and above all strategic stability. In early Roman period Romans created a shipping route from the Rhine towards the north by digging canals and constructing dams. This was done in order to submit the northern part of Germania through the Waddenzee and the German rivers Eems, Weser and Elbe. During the middle Roman period the Romans had canceled their efforts to submit Germania. In that period we know the River Rhine as the limes, which not only was a borderline of the Roman empire, but can also be seen as a guarded transport route. The research area is situated in the eastern part of the Rhine-Meuse river valley/delta system. The area represents a highly dynamic geological history of erosion and deposition close to the river system's equilibrium point. In order to reconstruct the former landscape and investigate whether traces of Roman waterworks could be indicated or disproved geoarchaeological coring campaigns have been carried out with lithological, textural and palaeoecological analyses. The results of the research presented in this poster will be: 1) Assessment of the condition of the covered Pleistocene sediments in the area, 2) Identification of the buried gullies and levees in the vicinity of the remains of the Roman castellum 'Carvium ad molem', which should have been built at the bifurcation of the delta branches of Rhine and Waal, 3) Chronological control of gullies and levees, 4) Landscape reconstruction in different time periods. Finally based on the geoarchaeological results a comment will be made on the location of the Drusus dam in the study area, the landscape context of the castellum and its position on the apex of the Insula Batavorum.

Human parasites in the Roman World: health consequences of conquering an empire.

PubMed

Mitchell, Piers D

2017-01-01

The archaeological evidence for parasites in the Roman era is presented in order to demonstrate the species present at that time, and highlight the health consequences for people living under Roman rule. Despite their large multi-seat public latrines with washing facilities, sewer systems, sanitation legislation, fountains and piped drinking water from aqueducts, we see the widespread presence of whipworm (Trichuris trichiura), roundworm (Ascaris lumbricoides) and Entamoeba histolytica that causes dysentery. This would suggest that the public sanitation measures were insufficient to protect the population from parasites spread by fecal contamination. Ectoparasites such as fleas, head lice, body lice, pubic lice and bed bugs were also present, and delousing combs have been found. The evidence fails to demonstrate that the Roman culture of regular bathing in the public baths reduced the prevalence of these parasites. Fish tapeworm was noted to be widely present, and was more common than in Bronze and Iron Age Europe. It is possible that the Roman enthusiasm for fermented, uncooked fish sauce (garum) may have facilitated the spread of this helminth. Roman medical practitioners such as Galen were aware of intestinal worms, explaining their existence and planning treatment using the humoural theory of the period.

Magnetic and electromagnetic prospections at the Roman city of Hadrianopolis, southern Albania

2017-04-01

We report on a combined magnetic-GPR survey performed in 2015-2017 at the ancient Roman city of Hadrianopolis, located in southern Albania, in the context of the project Teatri Antichi Riuniti (TAU). The collected data supplemented previous archaeological surveys performed by the University of Macerata with the aim of promoting the valley and starting the realization of an archaeological park. Hadrianopolis was founded through a reorganization of a previous Hellenistic settlement. Starting from 2015, magnetic and GPR surveys were carried out in Hadrianopolis in order to determine the urban framework. The collected data revealed the existence of structures organized along two main different patterns, which have been interpreted as due to the superposition of Roman buildings and Late Antiquity structures. In fact, the arrangement of structures in the studied area shows a regular urban organization of Roman type separated by a less regular disposition of the buildings that can be attributed to the Byzantine age. The latter arrangement is superimposed on the previous Roman structures. A stone wall, clearly identified by the combination of magnetic anomalies and GPR images, separates the Byzantine seattlement from the genuine Roman sector.

2017-09-01

A set of Roman Denarii from the republican to the imperial period (140BC-240AD) has been studied using X-ray fluorescent (XRF) scanning and proton induced x-ray emission (PIXE) techniques. XRF and PIXE are commonly used in the study of cultural heritage objects because they are nondestructive. The combination of these two methods is also unique because of the ability to penetrate the sample with a broader spectrum of depths and energies than either could achieve on its own. The coins are from a large span of Roman history and their analysis serves to follow the economic and political change of the era using the relative silver and copper contents in each sample. In addition to analyzing the samples, the study sought to compare these two common analysis techniques and to explore the use of a standard to examine any shortcomings in either of the methods. Data sets were compared and then adjusted to a calibration curve which was created from the analysis of a number of standard solutions. The concentrations of the standard solutions were confirmed using inductively coupled plasma spectroscopy. Through this we were able to assemble results which will progress the basis of understanding of PIXE and XRF techniques as well as increase the wealth of knowledge of Ancient Roman currency.

Mapping Findspots of Roman Military Brickstamps in Mogontiacum (Mainz) and Archaeometrical Analysis

NASA Astrophysics Data System (ADS)

Dolata, Jens; Mucha, Hans-Joachim; Bartel, Hans-Georg

Mainz was a Roman settlement that was established as an important military outpost in 13 BC. Almost 100 years later Mainz, the ancient Mogontiacum, became the seat of the administrative centre of the Roman Province of Germania Superior. About 3,500 brickstamps concerning to the period until the fall of the Roman Empire in the fifth century AD have been found in archaeological excavations. These documents have to be investigated based on several methods for a better understanding the history. Here the focus is on an application of spatial statistical analysis in archaeology. Concretely, about 250 sites have to be investigated. So, we compare maps of different periods graphically by nonparametric density estimation. Here different weights of the sites according to the radius of the finding area are taken into account. Moreover we can test whether archaeological segmentation is statistically significant or not. In combination of smooth mapping, testing and looking for dated brickstamps there is a good chance to achieve new sources for the Roman history of Mainz.

An inscription from the II century BC, dedicated to the Roman god Verminus and considered to be due to the rising threat of human worm infections, is studied from linguistic and historical points of view. Having analyzed the historical sources we have reached the conclusion that the erection of the shrine was not related to the human helminthosis but to the epidemic infectuous disease which affected both animal and humans.

Greco-Roman ethics and the naturalistic fantasy.

PubMed

Holmes, Brooke

2014-09-01

To modern scholars, the naturalistic fallacy looks out of place in Greco-Roman antiquity owing to the robust associations between nature, especially human nature, and moral norms. Yet nature was understood by ancient authors not only as a norm but also as a form of necessity. The Greco-Roman philosophical schools grappled with how to reconcile the idea that human nature is given with the idea that it is a goal to be reached. This essay looks at the Stoic concept of oikeiōsis as one strategy for effecting such a reconciliation. Drawing on natural history, these Stoic sources used examples of animal behavior to illustrate a process whereby nature "entrusts" all animals, including humans, with the care of their own survival. Nature is thus both what is given to the animal and what the animal achieves in a powerful but also problematic synthesis here called the "naturalistic fantasy".

The Roman-Irish Bath: Medical/health history as therapeutic assemblage.

PubMed

Foley, Ronan

2014-04-01

The invention of a new form of hot-air bath in Blarney, Ireland in 1856, variously known in its lifetime as the Roman-Irish or Turkish Bath, acted as the starting point for a the production of a globalised therapeutic landscape. Tracking the diffusion of the Roman-Irish bath template from its local invention in Ireland to a global reach across the Victorian world and recognizing its place within a wider hydrotherapeutic history, this paper frames that diffusion as a valuable empirical addition to assemblage theory. The specific empirical history of the spread of the Roman-Irish/Turkish bath idea is drawn from primary archival and secondary historical sources. It is then discussed and, drawing from work on assemblage theory, analyzed against three broad themes: mobile networks, socio-material practices and contested emergence. The emergent relational geographies of the Roman-Irish Bath identify important roles for the diffusion and transformation of specific medical settings, identities and functions. These were linked in turn to competing social-healing pathways wherein bodies were technologically and morally managed, to produce a more inhabited form of therapeutic assemblage. In all cases the differential diffusion of the bath idea, it's shifting and fractured material forms and multiple inhabitations and discourses were contested and mobile and spoke to an assemblage approach which has ripe potential for exploration across a range of medical/health geography settings.

Roman sophisticated surface modification methods to manufacture silver counterfeited coins

By means of the combined use of X-ray photoelectron spectroscopy (XPS), optical microscopy (OM) and scanning electron microscopy (SEM) coupled with energy dispersive X-ray spectroscopy (EDS) the surface and subsurface chemical and metallurgical features of silver counterfeited Roman Republican coins are investigated to decipher some aspects of the manufacturing methods and to evaluate the technological ability of the Roman metallurgists to produce thin silver coatings. The results demonstrate that over 2000 ago important advances in the technology of thin layer deposition on metal substrates were attained by Romans. The ancient metallurgists produced counterfeited coins by combining sophisticated micro-plating methods and tailored surface chemical modification based on the mercury-silvering process. The results reveal that Romans were able systematically to chemically and metallurgically manipulate alloys at a micro scale to produce adherent precious metal layers with a uniform thickness up to few micrometers. The results converge to reveal that the production of forgeries was aimed firstly to save expensive metals as much as possible allowing profitable large-scale production at a lower cost. The driving forces could have been a lack of precious metals, an unexpected need to circulate coins for trade and/or a combinations of social, political and economic factors that requested a change in money supply. Finally, some information on corrosion products have been achieved useful to select materials and methods for the conservation of these important witnesses of technology and economy.

Laser cleaning on Roman coins

Drakaki, E.; Karydas, A. G.; Klinkenberg, B.; Kokkoris, M.; Serafetinides, A. A.; Stavrou, E.; Vlastou, R.; Zarkadas, C.

Ancient metal objects react with moisture and environmental chemicals to form various corrosion products. Because of the unique character and high value of such objects, any cleaning procedure should guarantee minimum destructiveness. The most common treatment used is mechanical stripping, in which it is difficult to avoid surface damage when employed. Lasers are currently being tested for a wide range of conservation applications. Since they are highly controllable and can be selectively applied, lasers can be used to achieve more effective and safer cleaning of archaeological artifacts and protect their surface details. The basic criterion that motivated us to use lasers to clean Roman coins was the requirement of pulsed emission, in order to minimize heat-induced damages. In fact, the laser interaction with the coins has to be short enough, to produce a fast removal of the encrustation, avoiding heat conduction into the substrate. The cleaning effects of three lasers operating at different wavelengths, namely a TEA CO2 laser emitting at 10.6 μm, an Er:YAG laser at 2.94 μm, and a 2ω-Nd:YAG laser at 532 nm have been compared on corroded Romans coins and various atomic and nuclear techniques have also been applied to evaluate the efficiency of the applied procedure.

Asymmetric bias in perception of facial affect among Roman and Arabic script readers.

Heath, Robin L; Rouhana, Aida; Ghanem, Dana Abi

2005-01-01

The asymmetric chimeric faces test is used frequently as an indicator of right hemisphere involvement in the perception of facial affect, as the test is considered free of linguistic elements. Much of the original research with the asymmetric chimeric faces test was conducted with subjects reading left-to-right Roman script, i.e., English. As readers of right-to-left scripts, such as Arabic, demonstrated a mixed or weak rightward bias in judgements of facial affect, the influence of habitual scanning direction was thought to intersect with laterality. We administered the asymmetric chimeric faces test to 1239 adults who represented a range of script experience, i.e., Roman script readers (English and French), Arabic readers, bidirectional readers of Roman and Arabic scripts, and illiterates. Our findings supported the hypothesis that the bias in facial affect judgement is rooted in laterality, but can be influenced by script direction. Specifically, right-handed readers of Roman script demonstrated the greatest mean leftward score, and mixed-handed Arabic script readers demonstrated the greatest mean rightward score. Biliterates showed a gradual shift in asymmetric perception, as their scores fell between those of Roman and Arabic script readers, basically distributed in the order expected by their handedness and most often used script. Illiterates, whose only directional influence was laterality, showed a slight leftward bias.

The identity, legal status and origin of the Roman army's medical staff in the imperial age.

PubMed

Bader, Pascal

2014-01-01

More than a hundred epigraphic documents on different writing materials refer to medical staff in the Roman army. This paper focuses on the identity, legal status and origin of the Roman army medical staff--a topic which until now has hardly been studied. Various titles were conferred to a large number of medical staff in every unit of the Roman army; the doctors (medici) were the most numerous and had different ranks and status. The onomastic study of the inscriptions reveals a large proportion of Roman citizens in the military medical service. Most of them are ingenui with a Latin name, but freedmen with a Greek origin are frequently attested, though less so than among civilian doctors. These results dispel some misconceptions such as the Greek origin of most military doctors, which can be explained by the legal requirements of the recruitment into the Roman army.

Roman Travertine: proposed as a candidate for "Global Heritage Stone Resource" designation

NASA Astrophysics Data System (ADS)

Primavori, Piero

2017-04-01

Roman Travertine is one of the most long-standing and famous stones, used since the times of the Roman Empire. Together with Carrara and Botticino marbles, it is probably the most worldwide well-known and diffused Italian dimension stone. Travertine derives its name from the former town, known as Tibur in ancient Roman times; the ancient name for the stone was Lapis Tiburtinus, meaning Tibur Stone, which was gradually corrupted to Travertino (travertine). The Roman Travertine is geographically located circa 25 km to the east of Rome, Central Italy, in the hilly area of Guidonia-Montecelio and Tivoli. Its deposit, formed during late Pleistocene time over an active strike-slip fault nearby the Colli Albani quiescent volcano, is about 20 km2 wide and 60 m thick on average; the thickness is over 85 m toward its western N-S-elongated side, where thermal springs and large sinkholes occur in an aligned pattern. The first quarries date back to pre-Roman times; nowadays three main productive sub-zones can be recognized within the extractive basin: "Valle Pilella", "Barco" and "Le Fosse", where more than fifty quarries are in operation, together with a relevant number of processing plants and artisanal laboratories. Lithological and stratigraphical features allow the distinction of an extensive number of commercial varieties, being the most renowned the Classic, the Bianco, the Noce, the Paglierino, the Navona. Used since more than 2.500 years, the Roman Travertine has deeply characterized the architecture of Rome and its history, with the realization of villas, palaces, artistic and monumental buildings, and masterpieces with unmistakable features, such as the Anfiteatro Flavio (the Colosseum), the Theatre of Marcellus, the St. Peter's Basilica and Colonnade, the Tritone Fountain, the Adriana Villa, the Trevi Fountain, and many others. From Renaissance times on, the travertine has been extensively used to build an innumerable amount of churches, common buildings and houses

An interdisciplinary study of the archaeological landscape of the Trieste area (northeastern Italy), mainly based on airborne light detection and ranging (LiDAR), ground penetrating radar (GPR), and archaeological surveys, has led to the discovery of an early Roman fortification system, composed of a big central camp (San Rocco) flanked by two minor forts. The most ancient archaeological findings, including a Greco-Italic amphora rim produced in Latium or Campania, provide a relative chronology for the first installation of the structures between the end of the third century B.C. and the first decades of the second century B.C. whereas other materials, such as Lamboglia 2 amphorae and a military footwear hobnail (type D of Alesia), indicate that they maintained a strategic role at least up to the mid first century B.C. According to archaeological data and literary sources, the sites were probably established in connection with the Roman conquest of the Istria peninsula in 178-177 B.C. They were in use, perhaps not continuously, at least until the foundation of Tergeste, the ancestor of Trieste, in the mid first century B.C. The San Rocco site, with its exceptional size and imposing fortifications, is the main known Roman evidence of the Trieste area during this phase and could correspond to the location of the first settlement of Tergeste preceding the colony foundation. This hypothesis would also be supported by literary sources that describe it as a phrourion (Strabo, V, 1, 9, C 215), a term used by ancient writers to designate the fortifications of the Roman army.

Sinkholes are a well-known geologic hazard but their past occurrence, useful for subsidence risk prediction, is difficult to define, especially for ancient historic times. Consequently, our knowledge about Holocene carbonate landscapes is often limited. A multidisciplinary study of Trieste Karst (Italy), close to early Roman military fortifications, led to the identification of possible ancient road tracks, cut by at least one sinkhole. Electrical Resistivity Tomography through the sinkhole has suggested the presence of a cave below its bottom, possibly responsible of the sinkhole formation, while Ground Penetrating Radar has detected no tectonic disturbances underneath the tracks. Additionally, archaeological surveys led to the discovery of over 200 Roman shoe hobnails within or close to the investigated route. According to these data, the tracks are interpreted as the remains of a main Roman road, whose itinerary has been reconstructed for more than 4 km together with other elements of ancient landscape. Our results provide the first known evidence of a Roman main road swallowed by sinkholes and suggest that Holocene karst landscapes could be much different from what previously believed. In fact, sinkholes visible nowadays in the investigated region could have been flat areas filled by sediments up to the Roman time. PMID:29570732

To elucidate the evolution of society over time, ancient medicine is a very interesting and important researching field. Archaeological discoveries, such as the objects described by this article, but other ancient sources, also, are able to provide a complex framework of medical practice in Roman times. The geographic area that we have like target in this material is the province of Lower Moesia, which includes the territory between Danube and Black Sea (Romanian Dobrodja) and northern Bulgaria. In the present study we present nine ancient medical instruments, from a private collection: two tweezers, two ear probes, a probe-spatula, a probe-spoon, a spoon for pharmacy and two fragments of some kind of hooks used in surgical operations. Most likely, we have a mixed medical kit with tools used in general medicine, surgery, in preparation of the pharmaceutical treatments, but very possible, also, in cosmetic practices. Publication of these archaeological materials is, in addition to an extra page in the history of ancient medicine, a pretext for stepping up in a research field that, in other regions of the former Roman Empire, it is a great interest for researchers.

In the Roman period, urban and rural ways of living were differentiated philosophically and legally, and this is the first regional study of these contrasting life-ways. Focusing on frailty and mortality risk, we investigated how these differed by age, sex, and status, using coffin type as a proxy for social status. We employed skeletal data from 344 individuals: 150 rural and 194 urban (1st-5th centuries A.D.) from Dorset, England. Frailty and mortality risk were examined using indicators of stress (cribra orbitalia, porotic hyperostosis, nonspecific periostitis, and enamel hypoplastic defects), specific metabolic and infectious diseases (rickets, scurvy, and tuberculosis), and dental health (carious lesions and calculus). These variables were studied using Chi-square, Siler model of mortality, Kaplan-Meier analysis, and the Gompertz model of adult mortality. Our study found that overall, mortality risk and survivorship did not differ between cemetery types but when the data were examined by age, mortality risk was only significantly higher for urban subadults. Demographic differences were found, with urban cemeteries having more 0-10 and >35 year olds, and for health, urban cemeteries had significantly higher frequencies of enamel hypoplastic defects, carious lesions, and rickets. Interestingly, no significant difference in status was observed between rural and urban cemeteries. The most significant finding was the influence of the skeletal and funerary data from the Poundbury sites, which had different demographic profiles, significantly higher frequencies of the indicators of stress and dental health variables. In conclusion, there are significant health, demographic, and mortality differences between rural and urban populations in Roman Britain. © 2015 Wiley Periodicals, Inc.

The Roman Empire of the second century was a superpower that, in relative terms, dominated its world as much as the United States does today. In 166 AD, a plague broke out od pandemic proportions. The pandemic ravaged the entire extent of the Roman Empire, from its eastern frontiers in Iraq to its western frontiers on the Rhine River and Gaul, modern France, and western Germany. The disease is identified most often as smallpox, but it may have been anthrax. The study of bacterial DNA may enable identification of this plague that ravaged the Roman Empire at recurrent intervals for more than 100 years and that had a significant role in the decline and fall of this great superpower.

[Assumption of medical risks and the problem of medical liability in ancient Roman law].

PubMed

Váradi, Agnes

2008-11-02

The claim of an individual to assure his health and life, to assume and compensate the damage from diseases and accidents, had already appeared in the system of the ancient Roman law in the form of many singular legal institutions. In lack of a unified archetype of regulation, we have to analyse the damages caused in the health or corporal integrity of different personal groups: we have to mention the legal interpretation of the diseases or injuries suffered by serves, people under manus or patria potestas and free Roman citizens. The fragments from the Digest od Justinian do not only demonstrate concrete legal problems, but they can serve as a starting point for further theoretical analyses. For example: if death is the consequence of a medical failure, does the doctor have any kind of liability? Was after-care part of the healing process according to the Roman law? Examining these questions, we should not forget to talk about the complex liability system of the Roman law, the compensation of the damages caused in a contractual or delictual context and about the lex Aquilia. Although these conclusions have no direct relation with the present legal regulation of risk assumption, we have to see that analysing the examples of the Roman law can be useful for developing our view of a certain theoretical problem, like that of the modern liability concept in medicine as well.

The Roman Jewish community has been historically continuous in Rome since pre-Christian times and may have been progenitor to the Ashkenazi Jewish community. Despite a history of endogamy over the past 2000 yr, the historical record suggests that there was admixture with Ashkenazi and Sephardic Jews during the Middle Ages. To determine whether Roman and Ashkenazi Jews shared common signature mutations, we tested a group of 107 Roman Jews, representing 176 haploid sets of chromosomes. No mutations were found for Bloom syndrome, BRCA1, BRCA2, Canavan disease, Fanconi anemia complementation group C, or Tay-Sachs disease. Two unrelated individuals were positive for the 3849 + 10C->T cystic fibrosis mutation; one carried the N370S Gaucher disease mutation, and one carried the connexin 26 167delT mutation. Each of these was shown to be associated with the same haplotype of tightly linked microsatellite markers as that found among Ashkenazi Jews. In addition, 14 individuals had mutations in the familial Mediterranean fever gene and three unrelated individuals carried the factor XI type III mutation previously observed exclusively among Ashkenazi Jews. These findings suggest that the Gaucher, connexin 26, and familial Mediterranean fever mutations are over 2000 yr old, that the cystic fibrosis 3849 + 10kb C->T and factor XI type III mutations had a common origin in Ashkenazi and Roman Jews, and that other mutations prevalent among Ashkenazi Jews are of more recent origin.

It consisted of various ranks of military physicians (milites medici) and assistants (capsarii and marsi) as well as military hospitals (valetudinaria). These played a major part in the spread of rational medicine over the less civilized parts of the Roman empire.

The benefit of using chemical analysis in understanding archaeological glass. Case-study: Roman black glass

NASA Astrophysics Data System (ADS)

Cosyns, P.; Cagno, S.; Janssens, K.; Nys, K.

LA-ICP-MS is a well acquainted technique for the quantification of a wide range of minor and trace elements present in the glass matrix. The benefit to understand the changes in technological processes or the added value in assessing the provenance and chronology of the raw glass material is however rarely discussed. By selecting a set of 197 Roman black glass artifacts dating between the 1st and 5th century AD we aimed to contribute to this issue. The obtained data on the production of glass artifacts helps better understand the constantly evolving patterns in glass consumption throughout the Roman imperial period. The key trace elements linked with the sand generally show the use of Levantine and Egyptian raw glass to produce black glass artifacts and result in well defined clusters. These indications are evidence for the use of different raw glasses in the Roman Empire and therefore featuring the work of diverse workshops over time. Specific trace elements such as copper, cobalt and lead reflect the application of recycling glass in Roman times.

Lime-pozzolana mortars in Roman catacombs: composition, structures and restoration

DOE Office of Scientific and Technical Information (OSTI.GOV)

Sanchez-Moral, Sergio; Luque, Luis; Canaveras, Juan-Carlos

Analyses of microsamples collected from Roman catacombs and samples of lime-pozzolana mortars hardened in the laboratory display higher contents in carbonated binder than other subaerial Roman monuments. The measured environmental data inside the Saint Callistus and Domitilla catacombs show a constant temperature of 15-17 deg C, a high CO{sub 2} content (1700 to 3500 ppm) and a relative humidity close to 100%. These conditions and particularly the high CO{sub 2} concentration speed-up the lime calcitization roughly by 500% and reduce the cationic diffusion to form hydrous calcium aluminosilicates. The structure of Roman catacomb mortars shows (i) coarser aggregates and thickermore » beds on the inside, (ii) thin, smoothed, light and fine-grained external surfaces with low content of aggregates and (iii) paintings and frescoes on the outside. The observed high porosity of the mortars can be attributed to cracking after drying linked with the high binder content. Hardened lime lumps inside the binder denote low water/mortar ratios for slaking. The aggregate tephra pyroclasts rich in aluminosilicate phases with accessorial amounts of Ba, Sr, Rb, Cu and Pb were analysed through X-ray diffraction (XRD), electron microprobe analysis (EMPA) and also by environmental scanning electron microscopy (ESEM) to identify the size and distribution of porosity. Results support procedures using local materials, special mortars and classic techniques for restoration purposes in hypogeal backgrounds.« less

Lead sheathing of ship hulls in the Roman period: Archaeometallurgical characterisation

DOE Office of Scientific and Technical Information (OSTI.GOV)

Kahanov, Yaacov, E-mail: yak@research.haifa.ac.il; Ashkenazi, Dana

An archaeometallurgical analysis of samples of lead sheathing from five ships of the Roman period was carried out in order to determine their composition and microstructure, and to obtain a better understanding of their manufacturing processes. The examinations included optical microscopy of metallographic cross-sections, microhardness tests, scanning electron microscopy, including energy dispersive spectroscopy, and X-ray photoelectron spectroscopy. The results show that the samples were all composed of lead covered with an oxide layer. The sheet thicknesses, microhardness values and microhardness distribution, as well as the grain size distribution, led to the conclusion that all of the sheets were produced bymore » the same technology, using hammering, and were probably used for the same purpose. The presence of antimony was observed in the sample from the Roman ship from Caesarea, which may hint at an Italian (Sardinian) origin of the material, and perhaps of the ship. - Research Highlights: {yields} During the Roman period ship hulls were sheathed with lead. {yields} Five samples have been analysed for their characteristics and manufacturing process. {yields} The process was cold-working (strain-hardening) using hammering. {yields} The lead was open-casted on a flat stone, and later hammered at room temperature. {yields} Antimony in the Caesarea shipwreck may indicate an Italian origin of construction.« less

Previous anthropological investigations at Trentholme Drive, in Roman York identified an unusual amount of cranial variation amongst the inhabitants, with some individuals suggested as having originated from the Middle East or North Africa. The current study investigates the validity of this assessment using modern anthropological methods to assess cranial variation in two groups: The Railway and Trentholme Drive. Strontium and oxygen isotope evidence derived from the dentition of 43 of these individuals was combined with the craniometric data to provide information on possible levels of migration and the range of homelands that may be represented. The results of the craniometric analysis indicated that the majority of the York population had European origins, but that 11% of the Trentholme Drive and 12% of The Railway study samples were likely of African decent. Oxygen analysis identified four incomers, three from areas warmer than the UK and one from a cooler or more continental climate. Although based on a relatively small sample of the overall population at York, this multidisciplinary approach made it possible to identify incomers, both men and women, from across the Empire. Evidence for possible second generation migrants was also suggested. The results confirm the presence of a heterogeneous population resident in York and highlight the diversity, rather than the uniformity, of the population in Roman Britain.

A new approach to the study of Romanization in Britain: a regional perspective of cultural change in late Iron Age and Roman Dorset using the Siler and Gompertz-Makeham models of mortality

2011-01-01

This is the first study of Romanization to use the Siler and Gompertz-Makeham models of mortality in order to investigate the health consequences of the 43 AD conquest of Britain. The study examined late Iron Age and Romano-British populations (N=518) from Dorset, England, which is the only region of Britain to display continuity in inhumation burial practice and cemetery use throughout the two periods. Skeletal evidence for frailty was assessed using cribra orbitalia, porotic hyperostosis, periosteal lesions, enamel hypoplasia, dental caries, tuberculosis, and rickets. These health variables were chosen for analysis because they are reliable indicators of general health for diachronic comparison (Steckel and Rose 2002) and are associated with the introduction of urbanism in Britain during the Roman period (Redfern 2007; Redfern 2008b; Roberts and Cox 2003). The results show that levels of frailty and mortality were lower in the late Iron Age period, and no sex differences in mortality were present. However, post-conquest, mortality risk increased for children and the elderly, and particularly for males. The latter finding challenges received wisdom concerning the benefits of Romanization and the higher status of the male body in the Roman world. Therefore, we conclude that the consequences of urbanism, changes in diet and increased population heterogeneity negatively impacted health, to the extent that the enhanced cultural buffering of males did not out-weigh underlying sex differences in biology that advantage females.

Today's neuroanatomical terminology has its origins in the Romans' way of life, in their civil and military house architecture, as well as in the fields of engineering and technology. Despite the fact that they did not know how the nervous system worked and what the role of each neuroanatomic structure was, over time, especially in Renaissance and early modern times, the anatomists sought descriptive names for the nervous structures they have identified by way of similarity with some ancient items. This study aims to briefly review the influence of Roman architecture, engineering, and technology on neuroanatomic nomenclature, the precursor of modern neuroanatomical terminology.

Astrology in Ancient Greek and Roman Culture

Campion, Nicholas

2018-04-01

This article deals with astrology in Greek and Roman culture. It considers astrology's theoretical background, technical basis, interpretative conventions, social functions, religious and political uses, and theory of fate, as well as critiques of it. Astrology is the name given to a series of diverse practices based in the idea that the stars, planets, and other celestial phenomena possess significance and meaning for events on Earth. It assumes a link between Earth and sky in which all existence—spiritual, psychological, and physical—is interconnected. Most premodern cultures practiced a form of astrology. A particularly complex variety of it evolved in Mesopotamia in the first and second millennia BCE from where it was imported into the Hellenistic world from the early 4th century BCE onward. There it became attached to three philosophical schools: those pioneered by Plato, Aristotle, and the Stoics, all of which shared the assumption that the cosmos is a single, living, integrated whole. Hellenistic astrology also drew on Egyptian temple culture, especially the belief that the soul could ascend to the stars. By the 1st century CE the belief in the close link between humanity and the stars had become democratized and diversified into a series of practices and schools of thought that ranged across Greek and Roman culture. It was practiced at the imperial court and in the street. It could be used to predict individual destiny, avert undesirable events, and arrange auspicious moments to launch new enterprises. It could advise on financial fortunes or the condition of one's soul. It was conceived of as natural science and justified by physical influences, or considered to be divination, concerned with communication with the gods and goddesses. In some versions the planets were neither influences nor causes of events on Earth, but timing devices, which indicated the ebb and flow of human affairs, like the hands on a modern clock. Astrology had a radical view of

The TOTEM collaboration has developed and tested the first prototype of its Roman Pots to be operated in the LHC. TOTEM Roman Pots contain stacks of 10 silicon detectors with strips oriented in two orthogonal directions. To measure proton scattering angles of a few microradians, the detectors will approach the beam centre to a distance of 10 sigma + 0.5 mm (= 1.3 mm). Dead space near the detector edge is minimised by using two novel "edgeless" detector technologies. The silicon detectors are used both for precise track reconstruction and for triggering. The first full-sized prototypes of both detector technologies as well as their read-out electronics have been developed, built and operated. The tests took place first in a fixed-target muon beam at CERN's SPS, and then in the proton beam-line of the SPS accelerator ring. We present the test beam results demonstrating the successful functionality of the system despite slight technical shortcomings to be improved in the near future.

The Circular Mausoleum tomb in the Roman Necropolis of Carmona was carved on a calcarenite sequence in an ancient quarry located in the town of Carmona, Southern Spain. This rock-cut tomb, representative of Roman burial practices, currently suffers from serious deterioration. A detailed survey over several years permitted the identification of the main tomb's pathologies and damaging processes, which include loss of material (scaling, flaking, granular disintegration), surface modifications (efflorescences, crusts and deposits) and extensive biological colonization. The results obtained in this study indicated that anthropogenic changes were largely responsible and enhanced the main alteration mechanisms observed in the Circular Mausoleum. Based on the deterioration diagnosis, effective corrective actions were proposed. This study shows that any conservative intervention in the interior of the tomb should be preceded by accurate in situ measurements and laboratory analyses to ascribe the source of the deterioration damages and thus designing effective treatments.

Impact of explosive volcanic eruptions around Vesuvius: a story of resilience in Roman time

NASA Astrophysics Data System (ADS)

Scarpati, Claudio; Perrotta, Annamaria; De Simone, Girolamo Ferdinando

2016-03-01

Large explosive eruptions have reshaped the landscape around Vesuvius many times in prehistoric and historical times. Previous stratigraphic surveys suggested that people living in this area have probably abandoned their settlements (in the Bronze Age) or towns and villas (in the Roman period) for centuries after each major plinian eruption. New archaeological excavations on the northern slope of Vesuvius suggest a much more intriguing scenario. At Pollena Trocchia, an ongoing excavation has shown the superimposition of three different Roman structures, sandwiched between the deposits of the AD 79, AD 472, and AD 512 Vesuvius eruptions. Each of these eruptions more or less completely destroyed and buried the buildings under meters of volcanic products. Surprisingly, after a few years or decades, a new settlement was established exactly on the top of the buried one, indicating the immediate recovery of part of the devastated area. Our research documents the destruction of Roman buildings by volcanic eruptions over a period of five centuries (first to sixth century AD) and provides new insight into human behavior after major explosive eruptions.

Ancient Topometry, the Tracing of Towns in the Roman Epoch: Ulpia Traiana Dacica Sarmizegetusa - Romania. Second Part

Stanescu, Florin

2015-05-01

While following the rituals and the ancient topometrical methods used by the Romans in tracing cities according to the Etruscan tradition, this paper presents the historical, anthropological and archaeological aspects, analyzing techniques being used and aims at determining the day when there was inaugurated after the 2nd Dacian-Roman war, 105-106 AD, the new capital, Colonia Ulpia Traiana Augusta Dacica Sarmizegetusa, of the new province of Roman Empire, "Dacia Felix". The aspects of the problem which require a special archaeoastronomical and archaeometrical analysis are the physical horizon and the sun's movement. The provisional results obtained so far lead to the conclusion that the capital might have been traced in the 15-18 september period, that coincided with Emperor Trajan's birthday.

As part of the road widening scheme between London and Dover, Oxford Archaeology South uncovered a large boundary ditch of Iron Age origin that contained Iron Age and Roman inhumations, adjacent to which was a small mid-late Roman cemetery, interpreted as a rural cemetery for Romano-British farmers. Grave goods in the cemetery were restricted to a few individuals with hobnailed boots. Bulk bone collagen isotopic analysis of 11 skeletons of Iron Age and Roman date gave a typical C(3) terrestrial signal (average δ(13) C = -19.8‰, δ(15) N = 9.3‰), but also revealed one (SK12671) with a diet which included a substantial C(4) component (δ(13) C = -15.2‰, δ(15) N = 11.2‰). This is only the second such diet reported in Roman Britain. Subsequent δ(18) O(c) and (87) Sr/(86) Sr measurements on the dental enamel in this individual were, however, consistent with a "local" origin, indicating that either C(4) protein was consumed in Late Roman Britain, or that he came from somewhere else, but where conditions gave rise to similar isotopic values. If we accept the latter, then it indicates that using oxygen and strontium isotopes alone to identify "incomers" may be problematic. The provision of hobnailed boots for the dead appears to have had a strong symbolic element in Late Roman Britain. We suggest that in this case the boots may be significant, in that he was being equipped for the long march home. Copyright © 2011 Wiley-Liss, Inc.

Traditional and New Enhancing Human Cybernetic and Nanotechnological Body Modification Technologies: A Comparative Study of Roman Catholic and Transhumanist Ethical Approaches

NASA Astrophysics Data System (ADS)

Caligiuri, Michael J.

Advances in cybernetic and nanotechnological body modifications currently allow for enhancements to human physical and mental function which exceed human species-based norms. This thesis examines body modification and human enhancement from two perspectives---Roman Catholicism and Transhumanism--- in order to contribute to bioethical deliberations regarding enhancement technologies. Roman Catholicism has a longstanding tradition of bioethical discourse, informing the healthcare directives of Roman Catholic institutions. Transhumanism is more recent movement that endorses body modifications and human enhancements as a means of individual betterment and social evolution. The thesis first considers definitions of human enhancement and levels of normalcy in connection to cybernetic and nanotechnological bionic implants, and outlines a series of criteria to assess a technology's potential bioethical acceptability: implantability, permanency, power, and public interaction. The thesis then describes Roman Catholicism's response to non-enhancing decorative body modifications (cosmetic surgeries, common decorative modifications such as tattoos and piercings, and uncommon modifications such as scarifications and brandings) in order to establish a basis for possible Roman Catholic responses to enhancing cybernetic and nanotechnological modifications. This is followed by an analysis from a Roman Catholic perspective of the major social issues brought forward by enhancement technologies: commodification, eugenics, vulnerability, and distributive justice. Turning to Transhumanism, the thesis describes the origins and philosophy of the movement, and then discusses the bioethical principles it advances with regard to human enhancement. The thesis concludes by locating points of convergence between Transhumanism and Roman Catholicism that could be the basis of more widely accepted ethical guidelines regarding modification technologies.

Seventy-five specimens from thirty fragments of Roman villa wall-paintings from sites in Burgos Castilla y Leon, Spain, have been analysed by Raman spectroscopy. This is the first time that a Raman spectrocopic study of Roman wall-paintings from Spain has been reported. The extensive range of tonalities and colour compositions contrasts with the results found in other provinces of the Roman Empire, for example Romano-British villas. Calcite, aragonite, haematite, caput mortuum, cinnabar, limonite, goethite, cuprorivaite, lazurite, green earth, carbon and verdigris have been found as pigments. Some mineral mixtures with different tonalities have been made using different strategies to those more usually found. Of particular interest is the assignation of the Tarna mine for the origin of the cinnabar used for obtaining the red colour in some specimens analysed here. The wide range of colours, tonalities and minerals found in some of the sites studied in this work is suggestive of a high social status for the community.

We study five-dimensional superconformal field theories and their holographic dual, matter-coupled Romans supergravity. On the one hand, some recently derived formulae allow us to extract the central charges from deformations of the supersymmetric five-sphere partition function, whose large N expansion can be computed using matrix model techniques. On the other hand, the conformal and flavor central charges can be extracted from the six-dimensional supergravity action, by carefully analyzing its embedding into type I' string theory. The results match on the two sides of the holographic duality. Our results also provide analytic evidence for the symmetry enhancement in five-dimensional superconformal field theories.

The key role played by technology advancement with respect to the anticipated era of discovery and exploration (in space) is illustrated: how bold new initiatives may or may not be enabled. A truly enabling technology not only renders the proposed missions technically feasible, but also makes them viable economically; that is, low enough in cost (relative to the economy supporting them) that urgent national need is not required for justification, low enough in cost that high risk can be programmatically tolerated. A fictional parallel is drawn to the Roman Empire of the second century A.D., shown to have possessed by that time the necessary knowledge, motivation, means, and technical capability of mounting, through the use of innovative mission planning, an initiative similar to Columbus' voyage. They failed to do so because they lacked the advanced technology necessary to make it an acceptable proposition economically. Speculation, based on the historical perspective, is made on the outcome of contemporary plans for future exploration showing how they will be subjected to the same historical forces, within limits imposed by the state of technology development, that shaped the timing of that previous era of discovery and exploration.

2004-01-01

A reconstruction of the morphological features of domestic pigs from two Roman settlements is here suggested by means of the study of skeletal and dental remains, with the aim at evaluating their degree of selection in comparison with wild boars. Material was formed by 111 bone and tooth fragments and was uncovered during the excavations of Polybius' House in Pompeii and of Roman buildings in the neighbourhood of Caralis harbour (Sardinia). The remains underwent morphological examination. The eruption of permanent teeth and ossification of epiphyseal cartilages let us establish that most animals were over 18-20 months. When possible, the determination of sex was made by detecting tusk features. The presence of anthropic signs on the bone surface provides some information about slaughtering and cooking procedure in the Roman period and supports the hypothesis that the animal remnants were food remains. Osteometric analysis was carried out on long and short bones and teeth through suitable multiplicative parameters, leading to the assessment of the withers height and other main phenotypic features. Logarithmic deviation pointed out the significant osteometric differences between the domestic pigs from the two Roman settlements. These data were also compared with those from wild boars and modern crossbred wild boars X non-selected pigs. In conclusion, our data show that pigs from Caralis bear much resemblance to wild boars, whereas those from Pompeii appear to be improved, so sharing some phenotypic features of modem improved breeds.

Anatolia has been a home for ideas moving from all directions. So it is that in the Roman and post-Roman periods the role of Anatolia in general and of Ancyra (the Roman name of Ankara) in particular was of the greatest importance. Now, the visible archaeological remains of Roman period in Ankara are Roman Bath, Gymnasium, the Temple of Augustus of Rome, Street, Theatre, City Defence-Wall. The Caesar Augustus, the first Roman Emperor, conquered Asia Minor in 25 BC. Then a marble temple was built in Ancyra, the administrative capital of province, today the capital of Turkish Republic, Ankara. This monument was consecrated to the Empreror and to the Goddess Rome. This temple is supposed to have built over an earlier temple dedicated to Kybele and Men between 25 -20 BC. After the death of the Augustus in 14AD, a copy of the text of "Res Gestae Divi Augusti" was inscribed on the interior of the pronaos in Latin, whereas a Greek translation is also present on an exterior wall of the cella. In the 5th century, it was converted in to a church by the Byzantines. The aim of this study is to determine old buried archaeological remains in the Augustus temple, Roman Bath and in the governorship agora in Ulus district. These remains were imaged with transparent three dimensional (3D) visualization of the ground penetrating radar (GPR) data. Parallel two dimensional (2D) GPR profile data were acquired in the study areas, and then a 3D data volume were built using parallel 2D GPR data. A simplified amplitude-colour range and appropriate opacity function were constructed and transparent 3D image were obtained to activate buried

Throughout the centuries, anatomists attempting to denominate the new structures they discovered have found inspiration in the civilization of ancient Rome and the clothing worn by its citizens. This aricle presents the origins of seven neuroanatomical terms, fimbria, velum, funiculus, lemniscus, corona, splenium, and cingulum, inspired by the clothing and jewellery of Roman women and the military attire of Roman soldiers. Thus, through their apparel, the Romans influenced the Terminologia Anatomica and "clothed" the structures of the brain and spinal cord, making them immortal. Clin.

2010-01-01

The Stoics of the Roman Imperial period share the imperative that education should not focus on erudition for its own sake, but contribute to the pursuit of the good life as they define it in philosophical terms. Hence these later Stoics express similar concerns about the technical and theoretical aspects of philosophy as they do about…

Age-associated bone loss and intraskeletal variability in the Imperial Romans.

PubMed

Cho, Helen; Stout, Sam Darrel

2011-01-01

An Imperial Roman sample from the Isola Sacra necropolis (100-300 A.D.) offered an opportunity to histologically examine bone loss and intraskeletal variability in an urban archaeological population. Rib and femur samples were analyzed for static indices of bone remodeling and measures of bone mass. The Imperial Romans experienced normal age-associated bone loss via increased intracortical porosity and endosteal expansion, with females exhibiting greater bone loss and bone turnover rates than in males. Life events such as menopause and lactation coupled with cultural attitudes and practices regarding gender and food may have led to increased bone loss in females. Remodeling dynamics differ between the rib and femur and the higher remodeling rates in the rib may be attributed to different effective age of the adult compacta or loading environment. This study demonstrates that combining multiple methodologies to examine bone loss is necessary to shed light on the biocultural factors that influence bone mass and bone loss.

The ancient Roman city of Complutum (Alcalá de Henares, Madrid), founded in the 1st century AD, was one of the most important cities of Hispania. The old Roman city was destroyed, abruptly abandoned, relocated close by and rebuilt during the late 4th century AD. Destruction of the city and its relocation has not yet been explained by archaeologists. In this paper, with our multidisciplinary approach, we identify and characterize earthquake archaeological effects (EAEs) affecting the archaeological site, the La Magdalena, an agricultural holding 4 km from the core of Complutum. The most important EAEs in the site are liquefactions (sand dikes and explosive sand-gravel craters) affecting Roman structures, such as water tanks (cisterns), houses and graves. Ground liquefaction generated significant ground cracks, explosive craters and folds in foundations of buildings. Several other Roman sites throughout the valley were also abandoned abruptly during the 4th century AD, in some cases with EAEs of similar origin. This suggests the occurrence of a 5.0-6.6 Mw seismic event in the zone, in accordance with the minimum empirical limit of seismically-induced liquefaction and the maximum surface rupture length of the Henares fault.

2013-01-01

The increasing attention of archaeological and anthropological research towards palaepathological studies has allowed to focus the examination of many skeletal samples on this aspect and to evaluate the presence of many diseases afflicting ancient populations. This paper describes the most interesting diseases observed in skeletal samples from some necropoles found in urban and suburban areas of Rome during archaeological excavations in the last decades, and dating back to the Imperial Age. The diseases observed were grouped into the following categories: articular diseases, traumas, infections, metabolic or nutritional diseases, congenital diseases and tumours, and some examples are reported for each group. Although extensive epidemiological investigation in ancient skeletal records is impossible, the palaeopathological study allowed to highlight the spread of numerous illnesses, many of which can be related to the life and health conditions of the Roman population.

VAiRoma: A Visual Analytics System for Making Sense of Places, Times, and Events in Roman History.

2016-01-01

Learning and gaining knowledge of Roman history is an area of interest for students and citizens at large. This is an example of a subject with great sweep (with many interrelated sub-topics over, in this case, a 3,000 year history) that is hard to grasp by any individual and, in its full detail, is not available as a coherent story. In this paper, we propose a visual analytics approach to construct a data driven view of Roman history based on a large collection of Wikipedia articles. Extracting and enabling the discovery of useful knowledge on events, places, times, and their connections from large amounts of textual data has always been a challenging task. To this aim, we introduce VAiRoma, a visual analytics system that couples state-of-the-art text analysis methods with an intuitive visual interface to help users make sense of events, places, times, and more importantly, the relationships between them. VAiRoma goes beyond textual content exploration, as it permits users to compare, make connections, and externalize the findings all within the visual interface. As a result, VAiRoma allows users to learn and create new knowledge regarding Roman history in an informed way. We evaluated VAiRoma with 16 participants through a user study, with the task being to learn about roman piazzas through finding relevant articles and new relationships. Our study results showed that the VAiRoma system enables the participants to find more relevant articles and connections compared to Web searches and literature search conducted in a roman library. Subjective feedback on VAiRoma was also very positive. In addition, we ran two case studies that demonstrate how VAiRoma can be used for deeper analysis, permitting the rapid discovery and analysis of a small number of key documents even when the original collection contains hundreds of thousands of documents.

Roman culture employed architectural terracotta made from baked clay as original material to manufacture ceramic pieces. It was often used as a basis for construction of functional and/or decorative elements in roofs, such as plane and curve tiles as well as antefixes with their corresponding "imbrexes". Some of them are conserved nowadays. They were collected in Roman quarries discovered in old cities and villages sited in the Hispania Citerior (northeast of Spain in Roman age). A study of the origin and manufacturing process (moulding, baking, touching up and painting) of these terracotta pieces has been made on the basis of the data obtained from a physicochemical characterization of samples. The used techniques were mainly flame absorption and emission spectrometry for the elemental analysis (major and minor elements), dilatometry for the study of thermal behaviour, scanning electron microscopy (SEM) for observation of thin layers and X-ray diffraction spectrometry (XRD) for mineralogical composition. In addition, a supervised pattern recognition programme was applied to the results for a selected group of 85 samples and five variables (chromium, copper, lead, nickel and zinc contents). Dilatometry and SEM results showed baking temperatures of these materials below 900 degrees C and the existence of zones with very different porosity in the same ceramic piece. Results obtained from multielemental analysis and multivariate statistical study by linear discriminant analysis lead us to the following conclusions: (i) the high content of lead found in a large number of antefixes demonstrates the use of lead oxide as an additive in the lime grout treatment, (ii) different contents of Cu, Zn, Cr, and Ni were indicative of the use of varied clay types in the manufacture process (even in the same production centre) as well as of the existence of a pigmentation process, although this last affirmation is not corroborated by the presence of remains of evident painting in

A child from a Roman necropolis in Pécs, Hungary (4th century CE) was initially diagnosed with severe spinal osteomyelitis. The post-cranial skeleton displayed bone alterations in the lower thoracic and upper lumbar segments, including vertebral body destruction, collapse and sharp kyphosis, and additional multiple rib lesions, suggesting a most likely diagnosis of pulmonary and spinal tuberculosis. This study discusses a number of selected diagnoses in the context of our pathological findings, complementing the macroscopic examination with radiological and biomolecular analyses.

[A space for women in the Etruscan and Roman houses (VI-I cent. B.C.)?].

PubMed

Jolivet, Vincent

2011-01-01

The article analyzes the scientific discussion about the existence of a domestic space reserved to women in Etruscan and Roman houses. The hypotesis regarding the existence of a 'gynaeceum' has been recently proposed for the Etruscan houses built on Palatino in Rome (VI cent. B.C.) and for the ancient phase of the Centaurus Protodomus in Pompei. Considering the specific role of Roman matronae as laniferae, and also a substantial equality of social role between Etruscan men and women, it is possible to advance the hypotesis of the existence of a room originally reserved to women (oecus) on one side of the tablinum, the symmetrical room being reserved to men (triclinium).

The study area is located at S. Agata (Gera Lario), a small center at the northern end of Como Lake, near the junction of Valchiavenna and Valtellina Valleys. This site played a strategic role since ancient times, providing the control on the communications routes to both the Como Lake and the Spluga and Septimer alpine passes. Since the end of the last century archaeological findings are reported in literature, also supported, from the early XI century, by archival documents confirming the existence of the `Olonium' settlement, an administrative and fiscal center of primary importance, as well as a parish amongst the most influential in the Como Lake area. Within an area of 45,000 m 2 an electrical survey has been carried out in conjunction with magnetic and GPR investigations. These studies have indicated the presence of a number of sub-areas characterized by significant anomalies defined by the overlapping of the results obtained from two or more geophysical methods. In two of such sub-areas, excavation tests have been conducted, which have brought to light a number of archaeological findings of interest. In one of the two sub-areas, which is characterized by the superimposition of electrical and radar anomalies, a deposit of large pebbles has been found. The origin of this deposit has not been ascertained, whether it is of fluvial origin, related to the deviation of the Adda river in the Pian di Spagna region in Roman times, or it is part of reclamation works, still of Roman times, of paleolacustrine marshes. The overlapping stratigraphy, however, suggests the development of fluvial channels between Roman and Low-Medieval times. In the other sub-area, excavations were carried out on sites defined by electrical and radar anomalies, and confirmed by the results from magnetic survey. The excavations brought to light, below the fluvial deposits, a large medieval edifice, which could be identified as the S. Stefano church abandoned in 1444. The church is built on

[The Antonine Plague and the decline of the Roman Empire].

Sabbatani, S; Fiorino, S

2009-12-01

The Antonine Plague, which flared up during the reign of Marcus Aurelius from 165 AD and continued under the rule of his son Commodus, played such a major role that the pathocenosis in the Ancient World was changed. The spread of the epidemic was favoured by the occurrence of two military episodes in which Marcus Aurelius himself took part: the Parthian War in Mesopotamia and the wars against the Marcomanni in northeastern Italy, in Noricum and in Pannonia. Accounts of the clinical features of the epidemic are scant and disjointed, with the main source being Galen, who witnessed the plague. Unfortunately, the great physician provides us with only a brief presentation of the disease, his aim being to supply therapeutic approaches, thus passing over the accurate description of the disease symptoms. Although the reports of some clinical cases treated by Galen lead us to think that the Antonine plague was caused by smallpox, palaeopathological confirmation is lacking. Some archaeological evidence (such as terracotta finds) from Italy might reinforce this opinion. In these finds, some details can be observed, suggesting the artist's purpose to represent the classic smallpox pustules, typical signs of the disease. The extent of the epidemic has been extensively debated: the majority of authors agree that the impact of the plague was severe, influencing military conscription, the agricultural and urban economy, and depleting the coffers of the State. The Antonine plague affected ancient Roman traditions, also leaving a mark on artistic expression; a renewal of spirituality and religiousness was recorded. These events created the conditions for the spread of monotheistic religions, such as Mithraism and Christianity. This period, characterized by health, social and economic crises, paved the way for the entry into the Empire of neighbouring barbarian tribes and the recruitment of barbarian troops into the Roman army; these events particularly favoured the cultural and

Roman onyx glass: A study of production recipes and colorants, using PIXE spectrometry

NASA Astrophysics Data System (ADS)

Fleming, S. J.; Swann, C. P.

1994-03-01

The most attractive Roman glass produced during the latter half of the 1st century B.C. was mosaic ware — vessels and dishes molded from arrays of composite, multi-colored canes which create abstract floral and geometric designs. We have studied a range of such vessels, all of them colored amber and white in a way which was intended to imitate elite vessels that were carved from onyx stone. We have differentiated three ways in which onyx patterns were achieved in this glass. Taking advantage of the spatial resolution and detection sensitivity of PIXE spectrometry, we have studied the "recipes" for colorants used in these onyx patterns, thus raising the notion that each one may have been fashionable in just certain regions of the Roman World, and/or in vogue only during a certain time period.

Observations on a set of Greco-Roman eye, ear, nose, and throat surgical instruments.

PubMed

Dedo, Herbert H

2017-02-01

The tools described in this article are verified to be Greco-Roman medical and surgical instruments for the eye, ear, nose, and throat. They include three myrtle leaf-shaped scalpels, three ear spoons, a "Q-tip," a forceps, a needle, and two arrow-pointed scalpels. One of the arrow-pointed scalpels is nearly identical to a Juerger keratome, suggesting that in Roman times, cataracts were extracted, not just "couched" into the posterior chamber. The description presented here goes beyond traditional archeological claims, because as a head and neck surgeon, I evaluated these instruments from a surgeon's point of view. For example, nonsurgeon medical historians have claimed the myrtle leaf-shaped items were used as handles or for blunt dissection, which I feel is mistaken. Review of the literature reveals the Greco-Roman surgeons were doing tonsillectomies, tracheotomies, and cataract extractions, and recognized that swimming in dirty water could cause ear infection. However, it is clear that with poor or no anesthesia, the pain from blunt dissection would have been intolerable, and unnecessary tissue planes would have been opened increasing wound infection risks. Therefore, there would have been no need for the myrtle leaf-shaped blade if it were just a handle.

Sulfur isotope analysis of cinnabar from Roman wall paintings by elemental analysis/isotope ratio mass spectrometry--tracking the origin of archaeological red pigments and their authenticity.

The most valuable pigment of the Roman wall paintings was the red color obtained from powdered cinnabar (Minium Cinnabaris pigment), the red mercury sulfide (HgS), which was brought from mercury (Hg) deposits in the Roman Empire. To address the question of whether sulfur isotope signatures can serve as a rapid method to establish the provenance of the red pigment in Roman frescoes, we have measured the sulfur isotope composition (δ(34)S value in ‰ VCDT) in samples of wall painting from the Roman city Aventicum (Avenches, Vaud, Switzerland) and compared them with values from cinnabar from European mercury deposits (Almadén in Spain, Idria in Slovenia, Monte Amiata in Italy, Moschellandsberg in Germany, and Genepy in France). Our study shows that the δ(34)S values of cinnabar from the studied Roman wall paintings fall within or near to the composition of Almadén cinnabar; thus, the provenance of the raw material may be deduced. This approach may provide information on provenance and authenticity in archaeological, restoration and forensic studies of Roman and Greek frescoes. Copyright © 2010 John Wiley & Sons, Ltd.

2013-01-01

This paper deals with cases of diffuse idiopathic skeletal hyperostosis (DISH) found at the Late Roman Age necropolis in Pécs, Hungary (4th century AD). The skeletal remains of two male individuals, aged between 60-70 years and 45-55 years, displayed right-sided ossification of the anterior longitudinal ligament with extra-spinal manifestations typical in DISH cases. It is presumed that both male individuals were middle-class citizens. Their social status was supplemented with trace element analysis in order to reconstruct the dietary habits of the urban population. Concentrations of Sr and Zn indicated a predominantly vegetal diet. Potential DISH risk factors and associations were subsequently discussed and compared with our findings.

A health assessment for imperial Roman burials recovered from the necropolis of San Donato and Bivio CH, Urbino, Italy.

2009-01-01

Imperial Roman burials recovered from the sites of San Donato and Bivio CH, located in the city of Urbino, Italy were examined for skeletal lesions. Observed pathologies include arthritis, trauma, periostitis, cranial pitting and enamel hypoplasia. All of the adults exhibited at least one enamel hypoplasia. In general, the adult males exhibit greater rates of skeletal pathologies than the females. Clearly, chronic health problems appear to be common among all adults; nearly 89% of them exhibit at least one form of skeletal lesion. This is in stark contrast to what is seen for the sub-adults. Only one sub-adult showed skeletal lesions. Acute health problems may have been the primary contributing factors for the death of the children recovered from the site. Despite previous research and attention to malaria as a critical health problem of Roman sub-adults, it does not seem to be an issue for this burial sample. We compare the frequency of cranial pitting and periostitis for the Urbino burials to several other Imperial Roman skeletal samples as a means to assess the potential for malaria and other casual factors for the observed lesions. In conclusion, we see the extreme rate of skeletal lesions for this community as indication of an extremely poor quality of life for these Romans.

The semantics of pain in Greco-Roman antiquity.

PubMed

Wilson, Nicole

2013-01-01

The semantics of pain are an important and interesting aspect of any language. Ancient Greek and Latin had multiple words for pain, which makes scrutinizing different meanings problematic. The ancient physician Galen approached this issue through the use of adjectives to describe the qualities for pain, instead of the words for pain themselves. The medical texts of Celsus and Caelius Aurelianus reveal that Latin also vested particular significance in qualifiers to distinguish between different types of pain. This article looks at the qualifying terms used for pain in the ancient Greek and Latin languages to reveal a sophisticated Greco-Roman vocabulary for pain.

Zapata, J; Pérez-Sirvent, C; Martínez-Sánchez, M J; Tovar, P

2006-10-01

Bone element analysis of two Late Roman populations from coastal south-eastern Spain suggests significant diagenesis. Trace element levels, in particular elevated Sr, Pb, Al, Mn, and the Ca/P ratio indicate post-mortem changes in the composition of the bones, preventing use of the data for dietary reconstructions, as well as for the investigation of the different individuals' health conditions, or of links between diet, health and skeletal indicators of growth stress. Such diagenetic biases are more widespread than usually recognized; paleodietary and paleoenvironmental inferences derived from the chemistry of archaeological bones need to be critically assessed.

Roman and early-medieval routes in north-western Europe: modelling national and international frequent-travel zones in the Netherlands using a multi-proxy approach.

2016-04-01

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.

Computed tomography of a medium size Roman bronze statue of Cupid

2015-03-01

Diagnostics based on X-ray computed tomography (CT) are becoming increasingly important, not only in the medical field but in industry and cultural heritage. CT devices typical for medical applications, however, can seldom be used on art objects because both they are not easily transportable and they often present high X-ray absorption. It is therefore necessary to make use of portable instrumentation and/or to develop tomographic systems optimized to the characteristics of the objects under examination. This work describes the computed tomography of a first century A.D. Roman bronze statue of Cupid (96.AB.53) in the collection of the J. Paul Getty Museum, within the collaborative framework between the Getty Conservation Institute and the Department of Physics and Astronomy (DIFA) of the University of Bologna (Italy). The tomography performed at the Getty facilities employed a 450 kV X-ray tube and a detection system developed at DIFA. The study highlighted the casting and construction techniques used by Roman foundry workers and provided information on the status of conservation of the statue. A 3D virtual reconstruction allowed the user to define different cross-sections enabling the study of the internal features.

Landscape and vegetation change on the Iberian Peninsula during the Roman Epoch - A reconstruction based on Geo-Bioarchives

NASA Astrophysics Data System (ADS)

Schneider, Heike

2010-05-01

Archaeological investigations expect that first strong landscape changes on the Iberian Peninsula based on Roman Occupation (Schattner 1998, Teichner 2007). Actual sedimentological investigations in flood plains, lagoons and estuaries do not reflect this development. They often show a decrease in sedimentation during this period (Thorndycraft & Benito 2006 a/b). In contrast analyses on sediments from roman dams (Hinderer et al. 2004, Solanas 2005) document massive erosion processes. The aim of this presented project is to reconstruct the effects of the roman land use system on vegetation and landscape development. Therefore different Geo-Bioarchives on several sites of Portugal and Spain - estuaries, palaeoriver channels and roman dams - are actually investigated with a high temporal resolution using palynological and sedimentological methods. First results show, that the anthropogenic impact starts clearly before roman time with an peak in human activity during Iron Age (Schneider et al. 2008). During the roman occupation phase different effects are visible. The inland areas document a massive increase in vegetation change, while the coastal areas were stronger developed before and show only slightly and very local changes in land use and vegetation.

We construct a directed network using a dictionary of Greek and Roman mythology in which the nodes represent the entries listed in the dictionary and we make directional links from an entry to other entries that appear in its explanatory part. We find that this network is clearly not a random network but a directed scale-free network in which the distributions of out-degree and in-degree follow a power-law with exponents γout≈3.0 and γin≈2.5, respectively. Also we measure several quantities which describe the topological properties of the network and compare it to that of other real networks.

Radiological and multi-element analysis of sediments from the Proserpina reservoir (Spain) dating from Roman times.

The Proserpina dam was built in Roman times to provide drinking water to Emerita Augusta (today's Mérida in SW Spain). During maintenance work, a sediment core was extracted, offering an excellent opportunity to analyze the historical environmental impacts of the dam and its reservoir over the 2000 years since Roman times. In order to establish an accurate chronology, (14)C ages were determined by accelerator mass spectrometry (AMS). Core samples were assayed for their content in uranium and thorium series isotopes, (40)K, and the anthropogenic radionuclides (137)Cs, (90)Sr, and (239+240)Pu. Potassium-40 presented the highest activity level and was not constant with depth. The uranium and thorium series were generally in equilibrium, suggesting there had been no additional input of natural radionuclides. The presence of (137)Cs was only found in relation with the global fallout in the early 1960s. Multi-element assays were performed using the PIXE and PIGE techniques. Some variations in the multi-element concentrations were observed with depth, but the sediment core could be considered as clean, and no presumptive anthropogenic pollutants were found. Nevertheless, an unusually high Zn content was detected at depths corresponding to pre-Roman times, due to geological anomalies in the area.

"The first available written source in human history relating to the description of the life expectancy of a living population is a legal text which originates from the Roman jurist Ulpianus (murdered in AD 228). In contrast to the prevailing opinion in demography, I not only do consider the text to be of ¿historical interest'...but to be a document of inestimable worth for evaluating the population survival probability in the Roman empire. The criteria specified by Ulpianus are in line with the ¿pan-human' survival function as described by modern model life tables, when based on adulthood. Values calculated from tomb inscriptions follow the lowest level of the model life tables as well and support Ulpianus' statements. The specifications by Ulpianus for the population of the Roman world empire as a whole in the ¿best fit' with modern life tables lead to an average level of 20 years of life expectancy. As a consequence a high infant mortality rate of almost 400 [per thousand] can be concluded resulting in no more than three children at the age of five in an average family in spite of a high fertility rate."

Born in Pergamum in 129 A.D., Galen received his first medical training in his native city and then continued his studies in Smyrna, Corinth, and Alexandria. He began his medical career in Asia Minor, treating peasants and performing surgery on the gladiatorial troupe that worked as slaves under the high priest upon his return to Pergamum in 157. Subsequently, he settled in Rome, where he lived most of his life and treated many prominent patients. The aim of this paper is to explore how Galen viewed his Asian and Roman patients and how he adapted his practice and medical procedures based not only on each patient's social and economic status, but on his or her intellectual acumen and customs as well, through proposing an intelligent and original synthesis of Asian and Roman lifestyles.

Analysis of the Greenland ice core covering the period from 3000 to 500 years ago-the Greek, Roman, Medieval and Renaissance times-shows that lead is present at concentrations four times as great as natural values from about 2500 to 1700 years ago (500 B.C. to 300 A.D.). These results show that Greek and Roman lead and silver mining and smelting activities polluted the middle troposphere of the Northern Hemisphere on a hemispheric scale two millennia ago, long before the Industrial Revolution. Cumulative lead fallout to the Greenland Ice Sheet during these eight centuries was as high as 15 percent of that caused by the massive use of lead alkyl additives in gasoline since the 1930s. Pronounced lead pollution is also observed during Medieval and Renaissance times.

Fluvial lowlands have become attractive human settling areas all around the world over the last few millennia. Because rivers kept changing their course and networks due to avulsion, the sedimentary sequences in these areas are archives of both fluvial geomorphological and archaeological development. We integrated geological and archaeological datasets to demonstrate the concurrence of the gradual abandonment of a major Rhine channel (Utrecht, The Netherlands), the development of human habitation in the area, and the interactions between them. The Utrecht case study highlights the stage-wise abandonment of a natural river channel, due to avulsion, coincident with intensifying human occupation in Roman and Early Medieval times (1st millennium AD). The analyses make maximum use of very rich data sets available for the study area and the tight age control that the geo-archaeological dataset facilitates, offering extra means of time-control to document the pacing of the abandonment process. This allows us to quantify change in river dimensions and meander style and to provide discharge estimates for successive stages of the abandonment phase over a 1000-year period of abandonment succession, from mature river to eventual Late Medieval overbuilt canal when the Rhine branch had lost even more discharge. Continued geomorphic development during this period - which includes the 'Dark Ages' (450-1000 AD) - appears to have been crucial in the development of Utrecht from Roman army fortress to Medieval ecclesial centre. The settlement dynamics in and around the city of Utrecht changed during the various phases of abandonment. In the bifurcating network of river branches forming the Rhine-Meuse delta, the main Rhine branch hosted the Roman limes military border and transport route. The Rhine- Vecht bifurcation at Utrecht provided an excellent location to raise a Roman fort. Continued geomorphic activity during abandonment in Early Medieval times was characterised by enhanced

Styling one's hair seems to be an innate desire of humans to emphasize their beauty and power. As reviewed here, hairstyles were influenced by preceding cultures, by religion, by those depicted for gods and emperors on sculptures and coins. In addition, they were determined by aspects of lifestyle such as sports, wealth, and the desire to display inner feelings. The historical changes in fashions can be exemplarily followed by a visitor to an art collection of Graeco-Roman antiquity. The study of hairstyles permits an insight into very basic aspects of the self-conception of individuals and of the respective societies.

Analysis of metals with luster: Roman brass and silver

Non-destructive PIXE analysis using in-air proton beam was used for the studies of earliest brass coins issued during the 1st century BC by Greek cities in Asia Minor, Romans and Celts, and for the studies of plated low grade silver coins of the 3rd century AD. The analysis determined the levels of zinc and important trace elements, notably selenium, which confirms spread of selenium-marked copper from the east. For plating, combined tinning and silvering was identified by the mapping technique for the mid 3rd century AD, which evolved into mere plating by 270 AD.

The use of visible spectroscopy, applied to chromatic characterization of Roman wall paintings, allows an easy and trustworthy grouping of the samples studied. The use of other spectroscopic techniques such as Fourier transform infrared spectroscopy (FTIR) and energy-dispersive X-ray spectroscopy (EDS) in conjunction with X-ray diffraction (XRD) allows a good identification of the substances present in the pictorial layers that define and differentiate each chromatic group. In this paper, a study of 40 Roman wall painting samples, from Pinturas Báquicas of Casa del Mitreo in Emerita Augusta (Mérida, Spain), is described. In these samples, some pigments of high quality and cost, as well as some unusual mixtures, not described in the bibliography, have been found.

Theories on conception, the production of seed, the determination of the sex of the foetus, foetal development and parturition as expressed in the Gynaecia, a work of the fourth century AD Roman medical writer, Vindicianus, and the theories of Graeco-Roman predecessors ranging from the fifth century BC to the second century AD in which the Gynaecia is embedded, are compared with views occurring in Babylonian, Jewish and Biblical scriptures. The resemblances that have been found, are probably based on general observations found in any society rather than on direct influence by oral or literary tradition. It appears that the theories are determined by the cultural background of the various societies, and are a reflection of the focus of the group or individual(s).

A systematic dietary investigation during Danish Roman Iron Age (1-375AD) is conducted by analyzing stable isotope ratios of carbon (δ(13) C) and nitrogen (δ(15) N) in the collagen of human and animal bone. The human sample comprises 77 individuals from 10 burial sites. In addition 31 samples of mammals and fish were analyzed from same geographical area. The investigation characterizes the human diet among different social groupings and analyses dietary differences present between sex, age, and site phase groups. Diachronically, the study investigates the Roman influences that had an effect on social structure and subsistence economy in both the Early and Late Period. Geographically the locations are both inland and coastal. The isotopic data indicate extremely uniform diet both between and within population groups from Early and Late Roman periods and the data are consistent throughout the Roman Iron Age. Protein consumption was dominated by terrestrial animals with no differences among social status, age, sex, or time period, while terrestrial plant protein only seems to have contributed little in the diet. Furthermore, the consumption of marine or aquatic resources does not seem to have been important, even among the individuals living next to the coast. Copyright © 2010 Wiley-Liss, Inc.

The aim of the present work is the study of many fragments of wall painting from archaeological excavations in three different Roman age sites dating back to the I Century before Common Era: Pordenone (località Torre); Trieste (Crosada) and Padova (Montegrotto). The techniques used were optical microscopy, scanning electron microscopy (SEM), equipped with a EDS microanalysis detector, X-rays powder diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Fourier transform Raman spectroscopy (FT-Raman) and electron paramagnetic resonance (EPR) spectroscopy. The identified pigments were: cinnabar, hematite, celadonite, glauconite, cuprorivaite (Egyptian blue), yellow and red ochre, calcite, limonite, coal black. In general, the mortar preparation did not correspond to the complex procedure suggested by Vitruvius (De Architectura), but generally showed a porous layer, with crushed grains under the pigment layer. In some cases, two superimposed pigment layers were found: yellow superimposed on both red and pink, black on pink, green on black. The slight differences we found in the use of the pigments in the three studied sites might show that the same technology, culture and taste spread all over the Roman Empire in North Eastern Italy (X(a) Regio Venetia et Histria).

This is the first study of health in the Roman Empire to use the Siler and Gompertz-Makeham models of mortality to investigate the health consequences of the 43 AD conquest of Britain. The study examined late Iron Age and Romano-British populations (N = 518) from Dorset, England, which is the only region of Britain to display continuity in inhumation burial practice and cemetery use throughout the two periods. Skeletal evidence for frailty was assessed using cribra orbitalia, porotic hyperostosis, periosteal lesions, enamel hypoplasia, dental caries, tuberculosis, and rickets. These health variables were chosen for analysis because they are reliable indicators of general health for diachronic comparison (Steckel and Rose: The backbone of history: health and nutrition in the western hemisphere (2002)) and are associated with the introduction of urbanism in Britain during the Roman period (Redfern: J Rom Archaeol Supp Series 64 (2007) 171-194; Redfern: Britannia 39 (2008a) 161-191; Roberts and Cox: Health and disease in Britain: from prehistory to the present day (2003)). The results show that levels of frailty and mortality were lower in the late Iron Age period, and no sex differences in mortality was present. However, post-conquest, mortality risk increased for children and the elderly, and particularly for men. The latter finding challenges received wisdom concerning the benefits of incorporation into the Empire and the higher status of the male body in the Roman world. Therefore, we conclude that the consequences of urbanism, changes in diet, and increased population heterogeneity negatively impacted health, to the extent that the enhanced cultural buffering of men did not outweigh underlying sex differences in biology that advantage women. 2010 Wiley-Liss, Inc.

Serapis temple, which was constructed in the Roman period in the city of Pergamon (Bergama/Turkey), is one of the most important monuments of the world heritage. In this study, the characteristics of bricks and mortars used in the temple have been determined in order to define the necessary characteristics of the intervention materials, which will be used in the conservation works of the temple. Several analyses were carried out to determine their basic physical properties, raw material compositions, mineralogical and microstructural properties using X-ray diffraction, Scanning Electron Microscope and a Thermo Gravimetric Analyzer. Analysis results indicated that the mortars aremore » stiff, compact and hydraulic due to the use of natural pozzolanic aggregates.

Identification and impacts of earthquakes on the Roman Town of Patras- Archaeological evidence

NASA Astrophysics Data System (ADS)

Stamati, Alexandra-Venetia; Stiros, Stathis

2015-04-01

In this paper we examine the interactions between earthquakes and inhabitation history of the town of Patras (NW Peloponnese, Greece), flourishing during the Roman period. Instrumental seismicity data and the seismic history of the last two centuries indicate that the wider area is among the most seismically active parts of Europe. But surprisingly, for older periods no historical evidence of ancient earthquakes exists. If this absence of evidence of ancient earthquakes is indicative of a real absence of earthquakes, this may be important for different disciplines. For Seismology, it may perhaps indicate clusters of seismicity separated by intervals of quiescence, each at least several thousand years long. It may also indicate that the inhabitation history of Patras town was not interrupted by major natural catastrophic events, and some destruction observed in ancient remains can be assigned to anthropogenic effects. In order to contribute in the solution of this problem, we made a systematic Archaeoseismological investigation of Patras and examined for the first time several hundreds of reports of archaeological excavations that have been made during period of reconstruction of the city (1972-2004). Among these, about 100 reports provide evidence of destruction layers, some of which satisfy the criteria for identification of earthquakes from archaeological data. A further correlation of this evidence in space and time was made, and permitted to identify with certainty a few major seismic events which marked the history of Roman Patras (1st-6th century AD). In spite of their catastrophic effects, these earthquakes have not led to the abandonment of the ancient town (inhabitation hiatus), but have certainly left their marks in the urban and perhaps social and economic history of this Roman town. Some certain uniformity in the frequency of earthquakes in Patras was also inferred.

Neanderthal hunting strategies inferred from mortality profiles within the Abric Romaní sequence

Ungulate mortality profiles are commonly used to study Neanderthal subsistence strategies. To assess the hunting strategies used by Neanderthals, we studied the ages at death of the cervids and equids found in levels E, H, I, Ja, Jb, K, L and M of the Abric Romaní sequence. These levels date between 43.2 ± 1.1 ka BP (14C AMS) and 54.5 ± 1.7 ka BP (U-series). The degree of eruption and development of the teeth and their wear stages were used to determine the ages of these animals at death, and mortality profiles were constructed using these data. The equids display prime dominated profiles in all of the analyzed levels, whereas the cervids display variable profiles. These results suggest that the Neanderthals of Abric Romaní employed both selective and non-selective hunting strategies. The selective strategy focused on the hunting of prime adults and generated prime dominated profiles. On the other hand, non-selective strategies, involved the consumption of animals of variable ages, resulting in catastrophic profiles. It is likely that in the selective hunting events were conducted using selective ambushes in which it was possible to select specific prey animals. On the other hand, encounter hunting or non-selective ambush hunting may have also been used at times, based on the abundances of prey animals and encounter rates. Specific hunting strategies would have been developed accordance with the taxa and the age of the individual to be hunted. The hunting groups most likely employed cooperative hunting techniques, especially in the capture of large animals. Thus, it is not possible to uniquely associate a single mortality profile with the predation tactics of Neanderthals at Abric Romaní. PMID:29166384

The A.A. carried out a survey on hospital acquired infection (HAI) in the intensive care units (ICU) of five roman hospitals. The study monitored the following site-specific infection rates: pneumonia (PNE), blood stream infections (BSI), urinary tract infections (UTI), surgical site infections (SSI). According to CDC definitions all patients developing infection 48 hours or more after ward admission were included. Furthermore risk factors (i.e. age, sex, SAPS II), invasive procedures (i.e. endotracheal intubation, vascular and urinary catheterisation), microbiological isolates and their antibiotic susceptibility were screened. The overall 503 patients characteristics (i.e., age, length of stay, case-mix...) showed the wards as general ICU's. Although the SAPS II score was similar, mortality (18.2%-42.9%) and general infection rates (15.4%-40.4%) among the five ICU's were considerably variable (p < 0.05), as HAI episodes distribution by type: PNE (37-88%), BSI (6-42%), UTI (6-24%), SSI (3-7%) (p < 0.05). Also device-associated infection rates such as Ventilator-associated PNE (11.6-24.6@1000), Vascular catheter-associated BSI (3.4-19.2@1000). Urinary catheter-associated UTI (2.6-14.0@1000) and invasive procedures management were different. Among the infected patients the most commonly isolated microorganisms were P. aeruginosa and Staphylococcus spp., which presented a considerable antibiotic resistance. The study showed: 1) sampling (i.e. blood cultures, tracheal aspirate and urine samples) and laboratory methodology indispensable for a correct HAI diagnosis were not standardized in the five ICU's; 2) hospital infection control policy was not carried out in all ICU's. The study showed a lack of standardization which limits the comparability of the general roman ICU's.

Roman baths represented a popular social practice of everyday life, cited in numerous literary sources and testified by ample archaeological remains all over the Roman Empire. Although regional studies have contributed extensively to our knowledge about how baths functioned and what was their social role in various regions of the Mediterranean, their study in Cyprus is yet to be developed. Moreover, despite the increasing availability of devices and techniques for 3D documentation, various characteristics, especially in relation to the heating and water supply system of the baths, were omitted and were not properly and accurately documented. The pilot case study outlined in this paper presents the 3D documentation of the Roman bath, excavated in the 1950s, within the area of the Sanctuary of Apollo Hylates at Kourion (Limassol district). The creation of an accurate 3D model of the documented area through image and range based techniques combined with topographic data, allows the detailed analysis of architectural elements and their decorative features. At the same time, it enables accurate measurements of the site, which are used as input for the archaeological interpretation and virtual reconstruction of the original shape of the bath. In addition, this project aims to answer a number of archaeological research questions related to Roman baths such as their architectural features, function mode, and technological elements related to heating techniques.

The qualitative research design looked at priests' responses to the question, "Please share one or more sexual experiences in your lifetime." The qualitative responses were analyzed and categorized into seven groupings: (a) Childhood and adolescent homosexual experiences; (b) Childhood and adolescent heterosexual experiences; (c) Both homosexual and heterosexual childhood and adolescent experiences; (d) Adult sexual experiences before ordination to the priesthood; (e) Adult sexual experiences since ordination to the priesthood; (f) Masturbation; and (g) Other sexual experiences. The data were analyzed by frequency of responses and percentages within each of the seven categories. The results indicate the need for early intervention and education during seminary, ongoing education after ordination, and psychotherapy support for priests.

Some cartonnage fragments from Hawara, Fayoum Excavation were examined to identify pigments, media and grounds. It belonged to the Greek-Roman period. They were studied by X-ray diffraction (XRD), Energy dispersive X ray analysis (EDS) equipped with Scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). These techniques were used to identify the composition and morphology of grounds, nature of pigments and media used in cartonnage fragments. The coarse ground layer was composed of calcite and traces of quartz. The fine ground layer used under the pigments directly was composed of calcite only. Carbon black was used as black pigment while lead oxide as red pigment, showing the influence of Roman and Greek pigments on Egyptian art in these later periods. Blue colorant was identified as cuprorivaite and yellow pigment was goethite. Animal glue was used in the four pigments as medium colored.

The Iberians developed a surprisingly sophisticated culture in the Mediterranean coast of the Iberian Peninsula from the 6th century BC until their conquest by the Romans in the 2nd century BC. They spoke and wrote a non-Indo-European language that still cannot be understood; their origins and relationships with other non-Indo-European peoples, like the Etruscans, are unclear, since their funerary practices were based on the cremation of bodies, and therefore anthropology has been unable to approach the study of this people. We have retrieved mitochondrial DNA (mtDNA) from a few of the scarce skeletal remains that have been preserved, some of them belonging to ritualistically executed individuals. The most stringent authentication criteria proposed for ancient DNA, such as independent replication, amino-acid analysis, quantitation of template molecules, multiple extractions and cloning of PCR products, have been followed to obtain reliable sequences from the mtDNA hypervariable region 1 (HVR1), as well as some haplogroup diagnostic SNPs. Phylogeographic analyses show that the haplogroup composition of the ancient Iberians was very similar to that found in modern Iberian Peninsula populations, suggesting a long-term genetic continuity since pre-Roman times. Nonetheless, there is less genetic diversity in the ancient Iberians than is found among modern populations, a fact that could reflect the small population size at the origin of the population sampled, and the heterogenic tribal structure of the Iberian society. Moreover, the Iberians were not especially closely related to the Etruscans, which points to considerable genetic heterogeneity in Pre-Roman Western Europe.

The Roman and Islamic spice trade: New archaeological evidence.

Van der Veen, Marijke; Morales, Jacob

2015-06-05

Tropical spices have long been utilized in traditional medicine and cuisine. New archaeological evidence highlights temporal changes in the nature and scale of the ancient spice trade and in the ancient usage of these plants. Furthermore, a study of their 'materiality' highlights that the impact of spices extends beyond their material properties. Here the botanical remains of spices recovered from archaeological excavations at a port active in the Roman and medieval Islamic spice trade are evaluated. Recent excavations at Quseir al-Qadim, an ancient port located on the Red Sea coast of Egypt, have provided new evidence for the spice trade. Due to the arid conditions ancient botanical remains were preserved in abundance and these included spices, as well as a wide range of other food plants. Quseir al-Qadim was active as a transport hub during both the Roman and Islamic periods (ca. AD 1-250, known as Myos Hormos, and again during ca. AD 1050-1500, known as Kusayr), and the remains thus facilitate a study of temporal change in the trade and usage of these spices. Standard archaeobotanical methods were used to recover, identify and analyze these remains. At least seven tropical spices were recovered from the excavations, as well as several other tropical imports, including black pepper (Piper nigrum), ginger (Zingiber officinale), cardamom (Elettaria cardamomum), turmeric (Curcuma sp.), fagara (cf. Tetradium ruticarpum), myrobalan (Terminalia bellirica and Terminalia chebula) and betelnut (Areca catechu). A marked contrast between the two chronological periods in the range of spices recovered points to changes in the nature and scale of the trade between the Roman and medieval Islamic periods, while differences in the contexts from which they were recovered help to identify temporal changes in the way in which the spices were utilized during those periods. Archaeological and textual evidence suggest that in antiquity spices were used in ritual (funeral rites

The seismological catalogue for Algeria exhibits significant lack for the period before 1365. Some attempts led to retrieve ancient earthquakes evidenced by historical documents and achieves. Archaeoseismology allows a study of earthquakes that have affected archaeological sites, based on the analysis of damage observed on remains. We have focused on the Antiquity period that include Roman, Vandal and Byzantine period from B.C 146 to A.D. 533. This will contribute significantly to the understanding of seismic hazard of the Tell Atlas region known as an earthquake prone area. The Tell Atlas (Algeria) experienced during its history many disastrous earthquakes their impacts are graved on landscape and archaeological monuments. On Roman sites such, Lambaesis (Lambèse), Thamugadi (Timgad) Thibilis (Salaoua Announa) or Thevest (Tebessa), damage were observed on monuments and remains related to seismic events following strong shacking or other ground deformation (subsidence, landslide). Examples of observed damage and disorders on several Roman sites are presented as a contribution to Archaeoseismology in Algeria based on effects of earthquakes on ancient structures and monuments.

The restoration of historical buildings is very important for the history and culture of the cities and their population. It requires an advanced knowledge of the building materials used for the construction of these structures. Previously to any intervention in historical buildings, it is necessary a historic-scientific study of the original material. Historic mortars or concretes can reveal us different composition and the dependence on the geographical location and the time period of its construction. Historical concretes are complex systems that contain aerial or hydraulic binders or a blend of them, with aggregates, not always crystalline, and others elements that interact with the binder. The use of different techniques for microstructural characterization of materials, like optical microscopy, X-ray diffractometry or petrophysical analysis, allows the determination of the composition and some properties of these concretes. However, each technique has its own limits and, in many cases, several characterization techniques must be used to obtain coherent and reliable results. The present study focuses on the compositional characterization of Roman concrete from Roman buildings for public spectacles of Emerita Augusta, Mérida, Spain. An advanced knowledge of the Roman concrete composition is required to get a reliable restoration and preservation of these ancient monuments. Various samples of concrete were extracted from different zones from this archaeological site. The concrete was studied through mineralogical analysis (petrographic microscope and XRD) and petrophysical properties determination (bulk and real density, open porosity, mercury porosimetry intrusion, compressive strength and Ultrasound propagation velocity). The results obtained allow us to know the original composition of the concrete and the provenance of the aggregates used in it.

Outbred Roman high- (RHA) and low-avoidance (RLA) rats are selected for respectively rapid vs. poor acquisition of the active avoidance response and display different copulatory patterns when exposed to a sexually receptive female, with RHA rats showing more robust sexual motivation and better performance than RLA rats also after repeated sexual activity. Here we show that the distinct patterns of sexual behaviour of the Roman lines are correlated with differences in the activity of the dopaminergic mesolimbic system, which plays a key role in sexual motivation and copulatory performance. Thus, differential increases in the concentrations of dopamine and its main metabolite 3,4-dihydroxyphenylacetic acid, occurred in dialysates obtained from the nucleus accumbens shell of naïve and sexually experienced Roman rats during the anticipatory and consummatory phases of sexual activity. These differences were particularly evident between sexually naïve RHA and RLA rats and tended to diminish but still persisted between sexually experienced rats, as did the differences in sexual behaviour. Analysis of the biochemical and behavioural findings showed that, while in RHA rats sexual experience caused a shift in the changes in both the dopaminergic activity and copulation towards the first period of the sexual test, in RLA rats sexual experience increased dopaminergic activity and copulation throughout the entire test. Therefore, this study adds experimental support to the view that the different sexual patterns of the Roman lines are due, at least in part, to a more robust functional tone of the mesolimbic dopaminergic system of RHA rats.

Literary and Documentary Evidence for Lay Medical Practice in the Roman Republic and Empire.

Draycott, Jane

2016-01-01

The majority of surviving ancient medical literature was written by medical practitioners and produced for the purpose of ensuring the effective diagnosis and treatment of their patients, suggesting an audience of medical professionals ranging from instructors to students. This has led historians to concentrate on the professional medical practitioner and their theories, methods and practices, rather than on lay medical practitioners, or even patients themselves. This chapter seeks to redress this imbalance, and examine the ancient literary and documentary evidence for lay medical theories, methods and practices in the Roman Republic and Empire in an attempt to reconstruct the experiences of lay medical practitioners and their patients. The Roman agricultural treatises of Cato, Varro and Columella, papyri and ostraca from Egypt, and tablets from Britain are investigated, and it is established that the individual's personal acquisition of knowledge and expertise, not only from medical professionals and works of medical literature, but also from family members and friends, and through trial and error, was considered fundamental to domestic medical practice.

Health and disease in a Roman walled city: an example of Colonia Iulia Iader.

The paper presents the results of the bioarchaeological study of a Roman period (3rd-5th century) skeletal sample from Zadar, Croatia with the focus on subadult stress indicators (cribra orbitalia and dental enamel hypoplasia) and indicators of non-specific infectious diseases (periostitis). The total frequency of cribra orbitalia, an indicator of iron deficiency anaemia, in Zadar is 20.1%. Half of the subadult skeletons from Zadar exhibit signs of cribra orbitalia, of which two are in active form. Adults not affected by cribra orbitalia lived on average 4.5 years longer than individuals affected by this pathological change. Total frequency of dental enamel hypoplasia in adults is 61.1% with somewhat higher frequency in females. The frequency of periostitis in subadults (66.7%) is significantly higher than in adults (30.4%). A positive correlation was established between cribra orbitalia and periostitis in males. The presented data suggest relatively low quality of life in Roman Zadar, most probably due to the overcrowding inside the walled city which led to deterioration of sanitary conditions and the occurrence of infectious diseases.

The advances of computer games have shown their potentials for developing edutainment content and services. Current cultural heritages often make use of games in order to complement existing presentations, to create a memorable exhibition. It offers opportunities to reorganize and conceptualize historical, cultural and technological information or knowledge about the exhibits. To demonstrate the benefits of serious games in terms of facilitating the learning activities, we designed a video game about the Heerlen Roman bathhouse heritage. This paper explains the design considerations of this Roman bathhouse game, with a particular focus on the link between game play and learning. In addition, we have carried out a user study to observe and measure the learning effects of this game. Both quantitative and qualitative data are collected to analyze the performance of the learners. The results have shown that this game indeed can help learners understand the important historical facts and the related knowledge of the heritage being studied. Further directions include converting the first-person game into a third-person or multiple players' game.

The dried flowers of Chamaemelum nobile (L.) All. have been used in traditional medicine for different conditions related to the spasm of the gastrointestinal system. However, there have been no experimental studies to support the smooth muscle relaxant effect of this plant. The aim of our research was to assess the effects of the hydroethanolic extract of Roman chamomile, its fractions, four of its flavonoids (apigenin, luteolin, hispidulin, and eupafolin), and its essential oil on smooth muscles. The phytochemical compositions of the extract and its fractions were characterized and quantified by HPLC-DAD, the essential oil was characterized by GC and GC-MS. Neuronally mediated and smooth muscle effects were tested in isolated organ bath experiments on guinea pig, rat, and human smooth muscle preparations. The crude herbal extract induced an immediate, moderate, and transient contraction of guinea pig ileum via the activation of cholinergic neurons of the gut wall. Purinoceptor and serotonin receptor antagonists did not influence this effect. The more sustained relaxant effect of the extract, measured after pre-contraction of the preparations, was remarkable and was not affected by an adrenergic beta receptor antagonist. The smooth muscle-relaxant activity was found to be associated with the flavonoid content of the fractions. The essential oil showed only the relaxant effect, but no contracting activity. The smooth muscle-relaxant effect was also detected on rat gastrointestinal tissues, as well as on strip preparations of human small intestine. These results suggest that Roman chamomile extract has a direct and prolonged smooth muscle-relaxant effect on guinea pig ileum which is related to its flavonoid content. In some preparations, a transient stimulation of enteric cholinergic motoneurons was also detected. The essential oil also had a remarkable smooth muscle relaxant effect in this setting. Similar relaxant effects were also detected on other visceral

Geomorphological record of extreme wave events during Roman times in the Guadalquivir estuary (Gulf of Cadiz, SW Spain): An archaeological and paleogeographical approach

Analysis of the geological record has made it possible to delimit for the Guadalquivir estuary the traces of extreme wave events (EWEs) during the Roman period in the Iberian Peninsula (218 BCE to 476 CE). The largest event occurred in the 2nd-3rd century CE. It generated clearly visible erosive effects in the coastal barriers, including washover fans and erosional scarps. In the inner estuary, however, the effects were minor: crevasse splays that broke levees and cheniers, as well as a residual sedimentary lag. The significant development of the spits protected the inner estuary from the marine incursion, which only caused a water level rise with low-regime waves. Correlation of the geomorphological and sedimentary marks left by this event with the archaeological and geological evidence of other events recognized elsewhere in the Gulf of Cadiz effectively argues for a tsunami as to the nature of the 2nd-3rd century CE event. Yet this and the other identified EWEs in the Guadalquivir estuary during the pre-Roman and the Roman period all fit a model of paleogeographic evolution dominated by processes of coastal progradation and estuarine infilling. Radiocarbon dating, geomorphological analysis, and historical references fail to warrant the so-called '218-209 BCE' Atlantic tsunami, as hypothesized in the received scientific literature. In pre-Roman and Roman times, human occupation at the mouth of the Guadalquivir River was strongly influenced by various geodynamic processes, the location of the settlements being contingent upon dependable, fast communication with the sea and, above all, upon adequate protection from EWEs, on the leeward side of spits. Progressive progradation of these coastal barriers combined with the gradual infilling of the estuary to make navigation to open sea increasingly difficult and, eventually, to result in the abandonment of settlements.

Although domestication of the grapevine (Vitis vinifera L.) has been extensively documented, the history of genotype selection and evolution of vineyard management remain relatively neglected fields of study. The find of 454 waterlogged grapevine pips from a well-dated Etrusco-Roman site in the Chianti district (Tuscany, Central Italy) is an extraordinary chance to gain insights into the progress of viticulture occurring in a key historical period in one of the world's most famous wine regions. The molecular and geometrical analyses of grape seeds showed (a) the presence in the site of different grapevine individuals and (b) a sudden increase in pip size, occurring at around 200 BC, whic explainable by the selection and introduction of new varieties. In this period, the Etruscans settlers in Chianti were stimulated by northward-expanding Roman culture to use novel vineyard management practices. We hypothesize that one of the most important innovations may have been the introduction of pruning, inducing vine physiological conditions more favorable to pip growth. Such changes were the consequence of specific entrepreneurial choices made by the Romans in a period of economic investment in grape cultivation and wine making to satisfy the increased trade demand after the conquest of the Central-Western Mediterranean basin.

Using Oxygen and Carbon Isotopic Signatures in Order to Infer Climatic and Dietary Information in Roman Edessa, Greece

Michael, Dimitra-Ermioni; Dotsika, Elissavet

2017-12-01

Even though many isotopic studies have been conducted on ancient populations from Greece for the purpose of dietary reconstruction; mostly through carbon and nitrogen isotopic signals of bone collagen, less attention has been given to the utility of apatite signatures (oxygen and carbon) as dietary and palaeoenvironmental tools. Moreover, until recently the isotopic signal of tooth enamel for both the purposes of environmental and dietary reconstructions has been rarely assessed in ancient Greek societies. Therefore, the present study aims to provide with novel isotopic information regarding Edessa; a town in Northern Greece, during the Roman period. The current study primarily aims to explore the possible differentiation between the present climatic conditions in Edessa in relation to those occurring at the Roman period. Secondly, this study aims to reveal the significant utility of enamel isotopic signatures (carbon and oxygen) in palaeoenvironmental and palaeodietary studies regarding ancient human remains. The isotopic analyses have been conducted at the Stable Isotope and Radiocarbon Unit of INN, NCSR “Demokritos”. The population of Roman Edessa (2nd-4th c. AD) consists of 22 individuals, providing with 19 bone samples and 16 enamel ones. The mean enamel oxygen value is at -7.7 ±1.1 %0, the bone apatite mean oxygen value at -9.2 ±1.9 %0, and finally the mean carbon enamel value is at -11.7 ±1.2 %0. Oxygen values probably indicate that Edessa had a cooler climate during the Roman times in relation to present conditions, even though more research should be carried out in order to be more certain. In addition, the possible existence of non-local individuals has been revealed through the oxygen teeth enamel-bone apatite spacing. Finally, the carbon enamel signature has pointed out possible differentiations between the adult and the juvenile diet. Based on Edessa’s findings, the stated study strongly encourages the enamel oxygen and carbon isotopic signals

The Prodigies of The Albano Lake During Roman Age and Natural Hazard Assessment At Roma, Italy.

NASA Astrophysics Data System (ADS)

Funiciello, R.; Giordano, G.; de Rita, D.

Roma is built just 20 km to the northwest of the Pleistocene Colli Albani volcano, but is believed not exposed to relevant natural hazards, except for the Tiber river flood- ings, and local amplification of seismic waves from distal earthquakes. This belief has generally induced modern historians and geologists to discard as SmythologicalT the & cedil;many references to natural prodigies that are reported by many Roman-age historians. Recent studies have demonstrated that the Albano maar, the youngest volcanic cen- tre of the Colli Albani volcano and presently filled by a 175 m deep lake, protracted its activity to the Holocene triggering several catastrophic lahar events, likely related to lake withdrawal, the deposits of which are exposed to the southwest of Roma and reach its periphery. This finding youngs the history of the volcano and makes it rele- vant to pre-historic settlements, which ScarefullyT avoided the Albano maar slopes up & cedil;to the Bronze age. What is still unknown, though, is whether the lake experienced such fluctuations and overspills during historic times. Several Roman authors such as Ti- tus Livius, Dionigi d'Alicarnasso, Plutarco, Germanico, and many others wrote about the then well known 398 BC prodigious event, when, during the war between Roma and the Etruscan city of Veio, the gods anger caused the sudden rise and overspill of the Albano lake, reported as unrelated to climatic events, and the destructive flooding of the countryside. After that event Romans actually built a tunnel-drain which still operates regulating the lake level at 293 m a.s.l., 70 m below the maar rim elevation. Should those chronicles be truthful, we can join the geologic observation of Holocene lahar deposits from lake withdrawal with historical lake withdrawals, reassessing the natural hazard for the city of Roma under a point of view never explored before. This paper carefully explores the historical credibility of the 398 BC lake overspill event and its

Bioarchaeological Insights into the Process of Domestication of Grapevine (Vitis vinifera L.) during Roman Times in Southern France

Grapevine (Vitis vinifera), one of the most important fruit species in the Classical Mediterranean world, is thought to have been domesticated first in South-Western Asia, during the Neolithic. However, the domestication process remains largely unknown. Crucial unanswered questions concern the duration of the process (rapid or slow?) and the related geographical area (single or multiple-origins?). Seeds from domesticated grapevine and from its wild ancestor are reported to differ according to shape. Our work aims, first, to confirm this difference and secondly to identify the extent of domestication in the grapes cultivated by Romans in Southern France during the period 50 BCE–500 CE. We had the opportunity to analyze uncharred waterlogged grape pips from 17 archaeological sites. Based on an extended reference sample of modern wild grapevines and cultivars our work shows that both subspecies can be discriminated using simple measurements. The elongation gradient of the pip’s body and stalk may be regarded as an indicator of the strength of the selection pressures undergone by domesticated grapes. Grapevines cultivated during the Roman period included a mix of morphotypes comprising wild, intermediate and moderately selected domesticated forms. Our data point to a relative shift towards more selected types during the Roman period. Domestication of the grapevine appears to have been a slow process. This could result from the recurrent incorporation into cultivation of plants originating from sexual reproduction, when grape cultivation essentially relies on vegetative propagation. PMID:23690998

A comparison of female and male oral health in skeletal populations from late Roman Britain: implications for diet.

PubMed

Bonsall, L

2014-12-01

Textual sources from the Roman period point to the existence of dietary differences between the sexes. The aim of this study was to assess the palaeopathological evidence for such gender differences in dietary habits in Roman Britain by comparing the oral health of sexed individuals from two late Romano-British sites (Ancaster, Lincolnshire, and Winchester, Hampshire, England). Eighty-seven females (1243 teeth and 1950 sockets) and 112 males (1984 teeth and 2903 sockets) were examined for the presence of five dento-alveolar conditions, namely caries, calculus, periapical lesions, periodontal disease, and antemortem tooth loss. The frequency of each condition was calculated at the per individual and per tooth/socket level, and the results were compared between the sexes using Fisher's exact tests. Caries and antemortem tooth loss were slightly more common among women, but differences between the sexes were generally not significant. Males experienced higher rates of calculus and periodontal disease. There were no sex differences in the frequency of periapical lesions. Comparable rates of caries, periapical lesions and antemortem tooth loss in females and males indicate broad similarity in the diets of men and women. The greater levels of calculus and periodontal disease in males might point to some dietary differences, but could also be explained by non-dietary factors. Overall, the findings suggest that significant gender differences in diet, described in some contemporaneous textual sources, were not widely observed in Roman Britain. Copyright © 2014 Elsevier Ltd.

This paper presents the results derived from an archaeometric study undertaken on glass samples from the Roman town of Augusta Emerita (Mérida, Spain). The main goal of the research was to provide for the first time some compositional and technological insights into the glass finds unearthed in this town. Glass samples from different sites and chronology, either from inside or from outside the perimeter of the ancient town and from the first to the sixth century AD, were analyzed and characterized through optical microscopy (OM), scanning electron microscopy (SEM), energy dispersive X-ray microanalysis (EDS), X-ray fluorescence (XRF) spectrometry and VIS spectrophotometry. Resulting data indicated that all the samples studied were natron-based soda lime silicate glasses, even though two chronological and compositionally distinct groups were distinguished. One composed of Early Empire glasses and a second one composed of glasses from the fourth century AD onward, which was characterized by the presence of the so-called HIMT (high iron, manganese, and titanium) glasses. Comparison with coeval glasses suggested that Augusta Emerita shared the same trade glass circles than other contemporary Roman towns, within the frame of a secondary production scale. Finally, some outstanding differences connected to composition and chronology were found, since Late Roman glasses presented a higher and distinct degree of alteration than Early Empire ones.

A frequently overlooked aspect of the knowledge transfer from Arabic into Latin in the twelfth century is the introduction of the Islamo-Arabic calendar, which confronted Western computists with a radically different scheme of lunar reckoning that was in some ways superior to the 19-year lunar cycle of the Roman Church. One of the earliest sources to properly discuss this new system and compare it to the old one is the anonymous Collatio Compoti Romani et Arabici, found in a manuscript from Tewkesbury Abbey, Gloucestershire. This article contains the first edition and translation of this previously unknown text, preceded by an analysis of its content and sources. As will be argued, the text was written in the second quarter of the twelfth century as a reaction to the astronomical tables of al-Khwāizmī, recently translated by Adelard of Bath, as well as to eclipse observations that had exposed the flaws of the 'Roman' computation.

The idea of aromatherapy, using essential oils, has been considered as an alternative antidepressant treatment. In the present study, we investigated the effect of Roman chamomile essential oil inhalation for two weeks on depressive-like behaviors in Wistar-Kyoto (WKY) rats. We found that inhalation of either Roman chamomile or one of its main components α-pinene, attenuated depressive-like behavior in WKY rats in the forced swim test. Using isobaric tags for relative and absolute quantitation analysis (iTRAQ), we found that inhalation of α-pinene increased expression of proteins that are involved in oxidative phosphorylation, such as cytochrome c oxidase subunit 6C-2, cytochrome c oxidase subunit 7A2, ATPase inhibitor in the hippocampus, and cytochrome c oxidase subunit 6C-2, ATP synthase subunit e, Acyl carrier protein, and Cytochrome b-c1 complex subunit 6 in the PFC (prefrontal cortex). In addition, using the quantitative real-time polymerase chain reaction technique, we confirmed an increase of parvalbumin mRNA expression in the hippocampus, which was shown to be upregulated by 2.8-fold in iTRAQ analysis, in α-pinene treated WKY rats. These findings collectively suggest the involvement of mitochondrial functions and parvalbumin-related signaling in the antidepressant effect of α-pinene inhalation.

Abundant bog oak trunks occur in alluvial deposits of the Raba River in the village of Targowisko (southern Poland). Several of them contain galleries of the great capricorn beetle ( Cerambyx cerdo L.). A well-preserved subfossil larva and pupa, as well as adults of this species, are concealed in some of the galleries. These galleries co-occur with boring galleries of other insects such as ship-timber beetles (Lymexylidae) and metallic wood borers (Buprestidae). A dry larva of a stag beetle (Lucanidae) and a mite (Acari) have been found in the C. cerdo galleries. Selected samples of the trunks and a sample of the C. cerdo larva were dated, using radiocarbon and dendrochronological methods, to the period from 45 bc to ad 554; one sample was dated to the period from 799 to 700 bc. Accumulation of the channel alluvia containing the bog oak trunks is synchronous with the Roman Warm Period (late antiquity/Early Mediaeval times). The most recent part of this period correlates with massive accumulations of fallen oak trunks noted from various river valleys in the Carpathian region and dated to ad 450-570. The results indicate that C. cerdo was more abundant within the study area during the Roman Warm Period than it is today.

3D visualization of sheath folds in Ancient Roman marble wall coverings from Ephesos, Turkey

Wex, Sebastian; Passchier, Cees W.; de Kemp, Eric A.; İlhan, Sinan

2014-10-01

Archaeological excavations and restoration of a palatial Roman housing complex in Ephesos, Turkey yielded 40 wall-decorating plates of folded mylonitic marble (Cipollino verde), derived from the internal Hellenides near Karystos, Greece. Cipollino verde was commonly used for decoration purposes in Roman buildings. The plates were serial-sectioned from a single quarried block of 1,25 m3 and provided a research opportunity for detailed reconstruction of the 3D geometry of meterscale folds in mylonitized marble. A GOCAD model is used to visualize the internal fold structures of the marble, comprising curtain folds and multilayered sheath folds. The sheath folds are unusual in that they have their intermediate axis normal to the parent layering. This agrees with regional tectonic studies, which suggest that Cipollino verde structures formed by local constrictional non-coaxial flow. Sheath fold cross-section geometry, exposed on the surface of a plate or outcrop, is found to be independent of the intersection angle of the fold structure with the studied plane. Consequently, a single surface cannot be used as an indicator of the three-dimensional geometry of transected sheath folds.

Evidence is presented that the Roman emperor Maximinus Daia had Graves' disease and died of severe thyrotoxicosis. The information about this emperor's terminal illness is drawn from the writings of the 4th century writers Eusebius and Lactantius. An existing statue indicates that the emperor had bilateral Graves' ophthalmopathy.

[An archaelogical contribution to hygienical principles in the Roman town-planning].

Greek and Roman ancient medical writers suggest hygienical rules which are strictly dependent on the orientation of towns, the direction of winds and the quality of waters. According to Vitruvius, architects and builders should have some medical knowledge, together with a strong new interest towards the improvement of enviromental conditions. Norba, a little city never built up again after the Sillan distruction in 81 B.C., and Civitas Artena, quitted in the first century B.C., have been studied as significant exemples of this architectural behaviour. The construction of Villae - big country houses nearby the city - was conditioned by economics, easily available water, sunshine light and proximity to fruitful soils.

Comprehending and Rehabilitating Roman Catholic Clergy Offenders of Child Sexual Abuse.

Anderson, Jane

2015-01-01

Many have studied Roman Catholic clergy who have sexually abused children, but the range of investigations remains disconnected. This article brings together various disciplinary perspectives to form a comprehensive view. A review of the literature is first undertaken to comprehend how clergy offenders have been conceptualized in psychosocial, sociocultural, and moral-religious studies. These perspectives are then used as a foundation for examining how these clergy can be rehabilitated. Three rehabilitative modalities--psychological treatment, rehabilitation through restorative justice, and ritual healing--are explored. The article concludes with a discussion of the insights gained from the literature review and how the modalities can be advanced in an interdependent and considered approach.

The applicability of laser ablation multi-collector inductively coupled plasma-mass spectrometry (LA-MC-ICP-MS) for the determination of the B isotopic composition in Roman glasses was investigated. The δ11B values thus obtained provide information on the natron flux used during the glass-making process. The glass samples used for this purpose were previously characterized using pneumatic nebulization (PN) MC-ICP-MS. Unfortunately, this method is time-consuming and labor-intensive and consumes some 100 mg of sample, which is a rather high amount for ancient materials. Therefore, the use of the less invasive and faster LA-MC-ICP-MS approach was explored. In this work, the results for 29 Roman glasses and 4 home-made glasses obtained using both techniques were compared to assess the suitability of LA-MC-ICP-MS in this context. The results are in excellent agreement within experimental uncertainty. No difference in overall mass discrimination was observed between the Roman glasses, NIST SRM 610 reference glass and B6 obsidian. The expanded uncertainty of the LA-MC-ICP-MS approach was estimated to be < 2‰, which is similar to that obtained upon sample digestion and PN-MC-ICP-MS measurement.

2,000 Year old β-thalassemia case in Sardinia suggests malaria was endemic by the Roman period.

The island of Sardinia has one of the highest incidence rates of β-thalassemia in Europe due to its long history of endemic malaria, which, according to historical records, was introduced around 2,600 years ago by the Punics and only became endemic around the Middle Ages. In particular, the cod39 mutation is responsible for more than 95% of all β-thalassemia cases observed on the island. Debates surround the origin of the mutation. Some argue that its presence in the Western Mediterranean reflects the migration of people away from Sardinia, others that it reflects the colonization of the island by the Punics who might have carried the disease allele. The aim of this study was to investigate β-globin mutations, including cod39, using ancient DNA (aDNA) analysis, to better understand the history and origin of β-thalassemia and malaria in Sardinia. PCR analysis followed by sequencing were used to investigate the presence of β-thalassemia mutations in 19 individuals from three different Roman and Punic necropolises in Sardinia. The cod39 mutation was identified in one male individual buried in a necropolis from the Punic/Roman period. Further analyses have shown that his mitochondrial DNA (mtDNA) and Y-chromosome haplogroups were U5a and I2a1a1, respectively, indicating the individual was probably of Sardinian origin. This is the earliest documented case of β-thalassemia in Sardinia to date. The presence of such a pathogenic mutation and its persistence until present day indicates that malaria was likely endemic on the island by the Roman period, earlier than the historical sources suggest. © 2017 Wiley Periodicals, Inc.

2012-01-01

The increasing attention of archaeological and anthropological research towards palaeopathological studies has allowed to focus the examination of many skeletal samples on this aspect and to evaluate the presence of many diseases afflicting ancient populations. This paper describes the most interesting diseases observed in skeletal samples from five necropolises found in urban and suburban areas of Rome during archaeological excavations in the last decades, and dating back to the Imperial Age. The diseases observed were grouped into the following categories: articular diseases, traumas, infections, metabolic or nutritional diseases, congenital diseases and tumors, and some examples are reported for each group. Although extensive epidemiological investigation in ancient skeletal records is impossible, palaeopathology allowed highlighting the spread of numerous illnesses, many of which can be related to the life and health conditions of the Roman population.

Spirited dispute: the secret split between Wallace and Romanes.

PubMed

Elsdon-Baker, Fern

2008-06-01

Alfred Russel Wallace's role in prompting the original publication of "On the Origin of Species" is now generally acknowledged. Wallace is now widely recognised as 'Darwin's co-discoverer', but the role that he played in the development and promotion of Darwinism is more often overlooked. From the very beginning of their collaboration in 1858, there were important differences between the works of Wallace and Darwin. Within Darwin's lifetime, the two men also disagreed over several significant evolutionary debates, most notably the role that Natural Selection might play in evolution. Following Darwin's death in 1882, Wallace set about promoting his own version of 'Darwinism', but not without opposition. A rather ungentlemanly debate between Wallace and Darwin's chief disciple George John Romanes throws light on the contested nature of what it meant to be a Darwinian in the late nineteenth century.

Roman coloured and opaque glass: a chemical and spectroscopic study

2006-05-01

This work reports the results of an archaeometrical investigation of opaque Roman glass and is mainly focussed on the role of configuration and oxidation state of copper on the colour and opacity of red and green opaque finds (mosaic tesserae, game counters, and glass artefacts) from Sicily and Pompeii excavations. The glass fragments were characterised by EMPA, SEM-EDS, TEM, and XRPD analyses and the copper local environment was investigated using X-ray absorption spectroscopy. The analyses of high-resolution Cu-K edge XANES and EXAFS spectra suggest that, in red samples, copper is present as monovalent cations coordinated to the oxygen atoms of the glass framework, accompanied by metallic clusters. In green samples all the copper cations are incorporated in the glass matrix.

A selection of samples, obtained from a particular copper-alloy domestic artefact of Roman style from Pompeii, has been analysed by using different techniques (IR, Raman, SEM-EDX, FAAS), in order to investigate the chemical nature and composition of the metals utilised for such manufacturing pieces. The surface analysis of the bright red metallic microfragments conducted by different analytical techniques, emphasises the presence of pure unalloyed copper and confirms the absence of other metallic species on the upper layers. On the contrary, the mapping analysis of the section of the laminar metal of the investigated sample shows a consistent enrichment in tin content. Finally, destructive analysis by FAAS confirms that the artefact looks like a bronze metal alloy, with a medium Sn content of about 6.5%.

Weather extremes and the Romans - A marine palynological perspective on Italian temperature and precipitation between 200 BC and 500 AD

Sediments of a tephra-dated marine sediment core located at the distal part of the Po-river discharge plume (southern Italy) have been studied with a three annual resolution. Based on the variability in the dinoflagellate cyst content detailed reconstructions have been established of variability in precipitation related river discharge rates and local air temperature. Furthermore about the variability in distort water quality has been reconstructed. We show that both precipitation and temperature signals vary in tune with cyclic changes in solar insolation. On top of these cyclic changes, short term extremes in temperature and precipitation can be observed that can be interpreted to reflect periods of local weather extremes. Comparison of our reconstructions with historical information suggest that times of high temperatures and maximal precipitation corresponds to the period of maximal expansion of the Roman Empire. We have strong indications that at this time discharge waters might have contained higher nutrient concentrations compared to previous and later time intervals suggesting anthropogenic influence of the water quality. First pilot-results suggest that the decrease in temperature reconstructed just after the "Roman Optimum" corresponds to an increase in numbers of armored conflicts between the Roman and German cultures. Furthermore we observe a resemblance in timing of short-term intervals with cold weather spells during the early so called "Dark-Age-Period" to correspond to epidemic/pandemic events in Europe.

To evaluate the effect of hip position and lumbar posture on the surface electromyographic activity of the trunk extensors during Roman chair exercise. Descriptive, repeated measures. University-based musculoskeletal research laboratory. Twelve healthy volunteers (7 men, 5 women; age range, 18-35y) without a history of low back pain were recruited from a university setting. Not applicable. Surface electromyographic activity was recorded from the lumbar extensor, gluteal, and hamstring musculature during dynamic Roman chair exercise. For each muscle group, electromyographic activity (mV/rep) was compared among exercises with internal hip rotation and external hip rotation and among exercises by using a typical lumbar posture (nonbiphasic) and a posture that accentuated lumbar lordosis (biphasic). For the lumbar extensors, electromyographic activity during exercise was 18% greater with internal hip rotation than external hip rotation (P< or =.05) and was 25% greater with a biphasic posture than with a nonbiphasic posture (P< or =.05). For the gluteals and hamstrings, there was no difference in electromyographic activity between internal and external hip rotation or between biphasic and nonbiphasic postures (P >.05). The level of recruitment of the lumbar extensors can be modified during Roman chair exercise by altering hip position and lumbar posture. Clinicians can use these data to develop progressive exercise protocols for the lumbar extensors with a variety of resistance levels without the need for complex equipment.

Poor hamstring strength-endurance is a risk factor for hamstring injuries. This study investigated the effectiveness of the single-leg Roman hold and Nordic hamstring curl in improving hamstring strength-endurance. Twelve Gaelic footballers (mean ± standard deviation age, height and mass were 25.17 ± 3.46 years, 179.25 ± 5.88 cm, 85.75 ± 4.75 kilo) with a history of hamstring injury were randomized into 2 groups that performed 6 weeks of either Nordic hamstring curl, or single-leg Roman chair hold training. The single-leg hamstring bridge (SLHB) was measured pre- and post- intervention. The Roman chair group showed a very likely moderate magnitude improvement on SLHB performance for both legs (23.7% for the previously injured leg [90% confidence interval 9.6% to 39.6%] and 16.9% for the non-injured leg [6.2% to 28.8%]). The Nordic curl group showed a likely trivial change in SLHB performance for the non-injured leg (-2.1% [-6.7% to 2.6%]) and an unclear, but possibly trivial change for the previously injured leg (0.3% [-5.6% to 6.6%]). The Roman chair group improved very likely more with a moderate magnitude in both the non-injured (19.5% [8.0% to 32.2%]) and the previously injured leg (23.3% [8.5% to 40.0%]) compared to the Nordic curl group. This study demonstrated that 6-weeks single-leg Roman chair training substantially improved SLHB performance, suggesting that it may be an efficacious strategy to mitigate hamstring (re-) injury risk. Conversely, 6-weeks Nordic curl training did not substantially improve SLHB performance, suggesting this may not be the intervention of choice for modifying this risk factor.

Graeco-Roman Astro-Architecture: The Temples of Pompeii

Tiede, Vance R.

2014-01-01

Roman architect Marcus Vetruvius Pollio (ca. 75-15 BC) wrote, “[O]ne who professes himself as an architect should be…acquainted with astronomy and the theory of the heavens…. From astronomy we find the east, west, south, and north, as well as the theory of the heavens, the Equinox, Solstice and courses of the Stars.” (De Architectura Libri Decem I:i:3,10). In order to investigate the role of astronomy in temple orientation, the author conducted a preliminary GIS DEM/Satellite Imaging survey of 11 temples at Pompeii, Italy (N 40d 45', E 14d 29'). The GIS survey measured the true azimuth and horizon altitude of each temple’s major axis and was field checked by a Ground Truth survey with theodolite and GPS, 5-18 April 2013. The resulting 3D vector data was analyzed with Program STONEHENGE (Hawkins 1983, 328) to identify the local skyline declinations aligned with the temple major axes. Analysis suggests that the major axes of the temples of Apollo, Jupiter and Venus are equally as likely to have been oriented to Pompeii’s urban grid, itself oriented NW-SE on Mt. Vesuvius’ slope and hydraulic gradient to optimize urban sewer/street drainage (cf. Hodge 1992). However, the remaining nine temples appear to be oriented to astronomical targets on the local horizon associated with Graeco-Roman calendrics and mythology.

To find and analyze descriptions in ancient Greek and Roman literature that reveal what was known at the time about seasickness. A systematic search was made in the original literature beginning in the Greek period with Homer in ca 800 bc and extending up to Aetios Amidenos in the late Roman period in ca 600 ad. Rough seas and unpleasant odors were recognized as the major triggers; susceptibility was greater in persons not adapted to sea travel, of a labile mental state, or with anxiety; nausea, emesis, vertigo, anorexia, faintness, apathy, headache, and impending doom were frequently reported symptoms. Preventive and therapeutic measures included habituation to sea travel, looking at stationary contrasts on the coast, fasting or certain diets, inhaling pleasant fragrances, medicinal plants, and ingesting a mixture of wine and wormwood. The triggers, symptoms, and preventive measures of seasickness were well-known in antiquity. The implications for transport of troops and military actions were repeatedly described, e.g., by Livius and Caesar. At that time, the pathophysiologic mechanism was explained by the humoral theory of Empedokles and Aristoteles. Seneca Minor localized the bodily symptoms in various organs such as stomach, gullet, and esophagus, and also attributed them to an imbalance of bile. Recommended medication included ingestion of the plant white hellebore, a violent gastrointestinal poison. This remedy contains various alkaloids but not scopolamine, which today is the most effective anti-motion-sickness drug. © 2016 American Academy of Neurology.

Some notes on the Roman domination number and Italian domination number in graphs

Hajibaba, Maryam; Jafari Rad, Nader

An Italian dominating function (or simply, IDF) on a graph G = (V, E) is a function f : V → {0, 1, 2} that satisfies the property that for every vertex v ∈ V, with f(v) = 0, Σ u∈N(v) f(u) ≥ 2. The weight of an Italian dominating function f is defined as w(f) = f(V ) = Σ u∈V f(u). The minimum weight among all of the Italian dominating functions on a graph G is called the Italian domination number of G, and is denoted by γI (G). A double Roman dominating function (or simply, DRDF) is a function f : V → {0, 1, 2, 3} having the property that if f(v) = 0 for a vertex v, then v has at least two adjacent vertices assigned 2 under f or one adjacent vertex assigned 3 under f, and if f(v) = 1, then v has at least one neighbor with f(w) ≥ 2. The weight of a DRDF f is defined as the sum f(V) = Σ v∈V f(v), and the minimum weight of a DRDF on G is the double Roman domination number of G, denoted by γdR (G). In this paper we show that γdR (G)/2 ≤ γI (G) ≤ 2γdR (G)/3, and characterize all trees T with γI (T) = 2γdR (T)/3.

2013-06-01

We assessed the urinary indexes of hydration status of Greco-Roman wrestlers in an authentic precompetition situation at the time of official weigh-in (OWI). A total of 51 of 89 wrestlers competing in the Estonian Championship in 2009 donated a urine sample. Questionnaire responses revealed that 27 wrestlers (body mass losers (BMLs)) reduced body mass before the competition, whereas 24 wrestlers (those who do not lose body mass (n-BMLs)) did not. In 42 wrestlers, values of urine specific gravity ≥1.020 and urine osmolality ≥700 mOsmol·kg(-1) revealed a hypohydrated status. The prevalence of hypohydration in the BMLs (96%) was higher than in the n-BMLs (67%) (χ(2) = 7.68; p < 0.05). The prevalence of serious hypohydration (urine specific gravity >1.030) was 5.3 times greater (χ(2) = 8.32; p < 0.05) in the BMLs than in the n-BMLs. In the BMLs, the extent of body mass gain during the 16-h recovery (2.5 ± 1.2 kg) was associated (r = 0.764; p < 0.05) with self-reported precompetition body mass loss (4.3 ± 2.0 kg) and exceeded the body mass gain observed in the n-BMLs (0.7 ± 1.2 kg; p < 0.05). We conclude that hypohydration is prevalent among Greco-Roman wrestlers at the time of OWI. The prevalence of hypohydration and serious hypohydration is especially high among wrestlers who are accustomed to reducing body mass before competition. These results suggest that an effective rehydration strategy is needed for Olympic-style wrestlers, and that changes in wrestling rules should be considered to reduce the prevalence of harmful body mass management behaviours.

In the late Roman Republic period (2nd-1st century BC), in the area of San Giovanni on Elba Island, previously subject to intense extraction of iron ore, a rustic villa was established by Marco Valerio Messalla, a supreme Roman magistrate. The foundations of the walls were discovered and excavated by an archaeological mission. Palaeobotanical analysis of a set of stratigraphic layers was performed. Palynological slides showed remains of palynomorphic and non-pollen objects, while data combined with anthracological investigations confirmed the hypothesis that in the 1st century AD the villa was destroyed by a fire that created a compact crust under which were discovered four broken Roman amphorae containing about five hundred apple seeds. Comparisons of archaeological and fresh seeds from reference collections showed discontinuous morphology except for one group of archaeological samples. DNA was isolated from seeds that had well-preserved embryos in all groups. DNA extracts from archaeological, wild and modern domestic seeds (controls) were amplified by PCR and tested with SSR molecular markers, followed by genome analysis.

2016-10-01

Roman hypogea, vernacular settlements or crypts, are underground places characterised by specific and unique challenges (RH<90% and almost constant temperature throughout the whole year) related to their relative isolation from the outdoor environment. These sites often require adequate monitoring tools providing complete environmental information in order to carry out appropriate strategies for scheduling routine maintenance and designing suitable layouts for their preservation. In this work we present the results of a carefully planned thermo-hygrometric monitoring campaign conducted in a peculiar Roman building (130CE), the "Casa di Diana" Mithraeum, sited in Ostia Antica (archaeological site, Rome-Italy), with the aim of characterising the indoor environment as the structure suffers of several conservation problems (biocolonisation, efflorescences, evaporating and condensing cycle for wall-building materials). The campaign involving multipoint continuous measurement was carefully planned to better describe this micro-clime. In addition to underground environmental data available in literature, we have also performed, as a checkpoint control, a thermo-hygrometric monitoring campaign in the "Terme di Mitra" Hypogeum, a few meters from the "Casa di Diana". The recorded data was analysed by multivariate statistical and chemometric analyses. The results brought to light the presence of different microclimates (three areas) within a single Mithraeum: a room (pre-Mithraeum) and an area (Mithraeum: 2-4m) present a thermo-hygrometric environmental behaviour in accordance with a semi-confined environment, another area (Mithraeum: 1-2m) behaves accordingly with underground environments (although it cannot be described as such), and the last area (Mithraeum: 0-1m) where was recording RH values close to saturation (96-99%), associated with non-ventilated areas where the rising damp is "held" and not dispersed, describing an own micro-clime, comparable to a "small greenhouse

Inside and around the roman town of Grumentum: the contribution of LiDAR and historical air photography

The papers deals with the integration of aerial laser scanning, multitemporal satellite and aerial dataset to provide information on the 'forma urbis' of the Grumentum roman town, to detect new archaeological features in its close surrounding and to analyze changes of the landscape over the time. Grumentum is an ancient town, 50 km south of Potenza (Southern Italy), located near the 'Via Herculea' connecting Venusia, in the north est of Basilicata, with Heraclea in the Ionian coast. The first settlement date back to the 6th century BC. Then, it was resettled by the Romans in the 3rd century BC. The town, which evidences a long history from the Republican age to late Antiquity (III BC-V AD), is characterized by the typical urban pattern of 'cardi' and 'decumani'. Its excavated ruins include a large amphitheatre, a theatre, the thermae, the Forum and some temples. LiDAR data, adequately filtered, classified and post processed by using geostatistics methods(Lasaponara et al. 2012), enabled to detect features linked to tombs under a dense vegetation located close to the urban perimeter. The analysis of historical air photos, draped over the ground surface obtained from the LiDAR survey, put in evidence some unknown crop-marks linked to roman urban fabric. Finally, the same photos along with the satellite multitemporal dataset allowed us to reconstruct the recent history of the landscape from the Agrarian Reform, in the 50s, up today.

Roman mosaic glass: a study of production processes, using PIXE spectrometry

The most attractive Roman glass produced during the early part of the 1st century A.D. was mosaic ware - bowls and dishes molded from arrays of multi-colored canes that created abstract floral and geometric designs. Yet ancient literature tells us little about the organization of the glassworking industry in which such wares were produced. We have focused upon two kinds of mosaic decoration that include a component of white glass in their cane construction and have purple glass as their matrix. A consistent pattern in the minor levels of lead in each kind of glass suggests that they were the products of two separate workshops, each with separate sources of supply for their glass stock.

The plague under Commodus as an unintended consequence of Roman grain market regulation.

PubMed

Silver, Morris

2012-01-01

This paper begins with a review of Roman grain market policies. It is argued that policies such as forced sales and maximum prices made urban consumers hesitant to rely on the market for secure access to grain. Consequently, consumers hoarded grain in their homes. The hoarded grain formed a volatile fuel ready to be ignited by the arrival of the bubonic plague bacillus. This scenario fits events in the city of Rome under Commodus. Attested grain market interventions were followed by a severe epidemic, arguably bubonic plague, which decimated the city's population.

[Erotic temperance: fortune and development of an Epicurean suggestion in the imperial Roman age].

PubMed

Menghi, M

1999-01-01

The purpose of this writing is to follow the course of an idea, namely that of erotic temperance, which the Epicureans most proably derived as a corollary of their originary ethics. It was during the imperial Roman age that such an idea met a certain audience for different reasons, two of which at least cannot remain unnoticed. The first reason was the theoretical and clinic support given to this idea by such Epicurean oriented physicians as Rufus and Soranus, and by Areteus; the other one should have been the meeting of the notion of erotic temperance with such ethical principles as the moderation, the control of the passions, the impassibility of man towards life events, and a new vision the relationship between husband and wife, which entered into the pattern of the gentlemen's behaviour during the imperial age contributing to the starting of a new ethics. But, if erotic temperance represented on the one hand an ideal for the cultivated class of Roman imperial society, it was on the other perceived as a scrupulously observed realty by Germans, and as one of the principal reasons of their physical and mortal energy. Furthermore, the ideal of a severe erotic control of the early Christians offer precise evidence, will represent an important ground of agreement for theirs and contemporary pagan ethics.

The paper presents in detail the method used to acquire 2D and 3D representations for the Large Tower of the Roman fortress from Noviodunum (Isaccea, Tulcea County). The available implements were a total station, a digital camera and some software for handling data. The method is not new by any rate, but well fitted to the aims - recording archaeological data on ruined but massif walls, with rough surfaces - and with a limited budget. Lately considered as a low cost procedure, laser scanning is still costly and rare in some East-European countries. Our method, as simple as it is, provides reliable data as a 3D survey, along texture details, at the lowest price, on unfinished fieldwork, preserving and picturing a stage of knowledge about the site and the architectural bodies.

It was hypothesized that men and women living in the border provinces of the Roman Empire may have encountered different risks associated with their different occupations and activities. Limb bone trauma data were used to assess sex-based differences in physical hazards and evidence for fracture healing and treatment. Two hundred and ten skeletons were examined from a late 1st to early 4th century AD cemetery at Aquincum (Budapest, Hungary). Upper and lower limb bone fracture types, frequencies, distributions, and associated complications were recorded, and gendered patterns in injury risks were explored. Of the 23 fractures identified, both sexes had injuries indicative of falls; males exhibited the only injuries suggestive of higher-energy and more direct forces. Most fractures were well-healed with few complications. The extremity trauma at Aquincum suggests that people buried here experienced less hazardous physical activities than at other Roman provincial sites. The patterns of trauma indicate the occurrence of "traditional" gender roles, whereby male civilians participated in more physically dangerous activities than females. Additionally, treatment may have been equally accessible to men and women, but certain fracture types proved more challenging to reduce using the techniques available. Copyright © 2015 Elsevier Inc.

Ethics in medical technologies: the Roman Catholic viewpoint.

Zyciński, Joseph

2006-06-01

New medical techniques and novel scientific discoveries bring many basic questions concerning the role of human dignity in medical research as well as in the society of the future. This paper presents the Roman Catholic approach to the use of new technologies, the research of human embryos, the ethical aspects of studies on the human genome. The concept of "human ecology", as proposed by John Paul II, is introduced to reconcile the academic freedom of research with insurmountable ethical barriers which must be recognized to defend human dignity. In critical appraisal of Peter Singer's concept of the quality of life the author points out that it is irrational to try to reduce this quality to the level of biological parameters. Human dignity as well as the sanctity of life express also a quality of life so important for the cultural growth of Homo sapiens. To protect human ecology it is our moral duty to defend human dignity and to recognize the importance of those values that are fundamental in the process of development of the human species.

Paleoclimate of the Neoglacial and Roman Warm Period Reconstructed from Oxygen Isotope Ratios of Limpet Shells (Patella vulgata), Northwest Scotland

2010-12-01

Paleoclimate reconstructions from different regions have reported abrupt climate change around 2800-2700 cal yr B.P. The timing of this abrupt climate change is close to the boundary between the Neoglacial (3300-2500 cal yr B.P.) and Roman Warm Period (2500-1600 cal yr B.P.). However, temporal and spatial variability observed in this climate change event raises controversies about the forcing factors driving it and why it has regional variability. Scotland lies in the North Atlantic Ocean, which responds sensitively to climate change. Therefore, even in the case of subtle climate change, the climate variability of Scotland should be able to capture such change. In this study, we expect that paleoclimate reconstructions of the Neoglacial and Roman Warm Period in Scotland will help improve our knowledge of abrupt climate change at 2800-2700 cal yr B.P. Archaeological shell deposits provide a rich source of climate proxy data preserved as oxygen isotope ratios in shell carbonate. Croig Cave on the Isle of Mull, Scotland, contains a nearly continuous accumulation of shells ranging from 800 BC-500 AD and possibly older. This range represents a broad chronology of human use from the late Bronze to Iron Ages and spans the Neoglacial through Roman Warm Period climate episodes. Here, we present seasonal temperature variability of the two climate episodes based on oxygen isotope ratios of ten limpet shells (Patella vulgata) from Croig Cave. Based on AMS dating (2 sigma calibration), the oldest shell was from 3480-3330 cal yr B.P. and the youngest shell was from 2060-1870 cal yr B.P. Our results indicated that estimated temperatures from the Neoglacial limpets average 6.44±0.56°C for coldest winters and 15.06±0.67°C for warmest summers. For the Roman Warm Period limpets, the average is 5.68±0.36°C for coldest winters and 14.14±0.81°C for warmest summers. We compared our estimated temperatures to the present sea surface temperature (SST) from 1961 to 1990 near our

In the last decades, damages on building materials and mural paintings were observed in Roman catacombs. The damages were due to extensive formation of biofilms induced by artificial illumination and humidity. Microenvironmental data (temperature, CO(2) concentration, humidity, and atmospheric pressure) clearly showed the negative influence of visitors. Increasing heat, light and water vapour condensation into corridors and cubicles favoured biofilm development. The composition of biofilms was different and depended mainly on distance to illumination sources and humidity, thus denoting the influence of light on the growth of phototrophic microorganisms in the catacombs. In addition, biofilm distribution was governed by the type of material to be colonised. This study shows that countermeasures are needed to prevent deterioration of hypogean environments.

Hermaphroditus in Greco-Roman myth: lessons and hypotheses for intersex today.

PubMed

Jospe, Nicholas; Florence, Monica

2004-11-01

This discussion reviews the Greco-Roman mythic origins of the eponymic Hermaphroditus. It reviews the two major tales, one Greek, the other from Ovid, regarding the origins of the sexual and gender predicament of Hermaphroditus. It explains the genealogy of Hermaphroditus in Greek mythology, and includes a discussion of Ovid's text on Hermaphroditus. A comparison of the two renditions offers the opportunity to reflect on who Hermaphroditus may have been, and to reflect on the implications of his nature. The discussion also attends to some of the ethical and emotional conflicts for the intersexed today. Finally, the discussion explores whether lessons from, and hypotheses regarding a mythic figure, such as Hermaphroditus, may provide guidance for intersexed individuals and their parents.

Phylogeography: English elm is a 2,000-year-old Roman clone.

The outbreak of Dutch elm disease in the 1970s ravaged European elm populations, killing more than 25 million trees in Britain alone; the greatest impact was on Ulmus procera, otherwise known as the English elm. Here we use molecular and historical information to show that this elm derives from a single clone that the Romans transported from Italy to the Iberian peninsula, and from there to Britain, for the purpose of supporting and training vines. Its highly efficient vegetative reproduction and its inability to set seeds have preserved this clone unaltered for 2,000 years as the core of the English elm population--and the preponderance of this susceptible variety may have favoured a rapid spread of the disease.

Trade and Transport in Late Roman Syria

NASA Astrophysics Data System (ADS)

Fletcher, Christopher

Despite the relative notoriety and miraculous level of preservation of the Dead Cities of Syria, fundamental questions of economic and subsistence viability remain unanswered. In the 1950s Georges Tchalenko theorized that these sites relied on intensive olive monoculture to mass export olive oil to urban centers. Later excavations discovered widespread cultivation of grains, fruit, and beans which directly contradicted Tchalenko's assertion of sole reliance on oleoculture. However, innumerable olive presses in and around the Dead Cities still speak to a strong tradition of olive production. This thesis tests the logistical viability of olive oil transportation from the Dead Cities to the distant urban centers of Antioch and Apamea. Utilization of Raster GIS and remote sensing data allows for the reconstruction of the physical and social landscapes of Late Roman Syria. Least Cost Analysis techniques produce a quantitative and testable model with which to simulate and evaluate the viability of long distance olive oil trade. This model not only provides a clearer understanding of the nature of long distance trade relationships in Syria, but also provides a model for investigating ancient economic systems elsewhere in the world. Furthermore, this project allows for the generation of new information regarding sites that are currently inaccessible to researchers.

The Roman pots of the TOTEM experiment at LHC will be equipped with edgeless silicon micro-strip detectors. A detector package consists of 10 detector planes cooled at -15C in vacuum. The detector resolution is 20 μm, the overall alignment precision has to be better than 30 μm. The detector planes are composed of a kapton hybrid glued on a substrate made of low expansion alloy, CE07 with 70% Si and 30% Al. An evaporative cooling system based on the fluorocarbon C3F8 with oil-free compressors has been adopted. The throttling of the fluid is done locally through capillaries. A thermo-mechanical prototype has been assembled. The results fully match the requirements and the expectations of calculations. They show a low thermal gradient on the cards and a uniform temperature distribution over the 10 planes.

In ancient Egypt mummifications were first carried out around 3000 BC. The visceral organs (lungs, stomach, liver and bowel) were removed from the body, cleansed, desiccated and placed in four canopic jars. The brain was removed from the body but was not preserved. Exactly how removal of the brain was accomplished is not clear. This study investigated the route of brain removal during mummification. Nasal endoscopy was carried out on 20 Pharaonic and Roman mummies. CT examination was performed on 2 mummy heads. In all mummies a communication between the cranial and nasal cavities was found passing through the posterior ethmoids and cribriform plates. The cranial cavity was empty. Our results demonstrate that brain removal during mummification was performed endonasally by trained personnel with a good knowledge of anatomy, using special instruments capable of creating a clean-cut endonasal craniotomy.

The current understanding of child morbidity in Roman England is dominated by studies of single sites/regions. Much of the data are derived from third to fifth century AD Poundbury Camp, Dorchester, Dorset, considered an unusual site due to high levels of non-adult morbidity. There is little understanding of children in rural areas, and whether Poundbury Camp was representative of Romano-British childhood. The study provides the first large scale analysis of child health in urban and rural Roman England, adding to the previously published intra-site analysis of non-adult paleopathology at Poundbury Camp. Age-at-death and pathology prevalence rates were reassessed for 953 non-adults (0-17 years) from five major urban, six minor urban, and four rural sites (first to fifth century AD). The data were compared to the results from 364 non-adults from Poundbury Camp. Rural sites demonstrated higher levels of infant burials, and greater prevalence of cribra orbitalia in the 1.1-2.5 year (TPR 64.3%), and 6.6-10.5 year cohorts (TPR 66.7%). Endocranial lesions were more frequent in the minor urban sample (TPR 15.9%). Three new cases of tuberculosis were identified in urban contexts. Vitamin D deficiency was most prevalent at Poundbury Camp (CPR 18.8%), vitamin C deficiency was identified more frequently in rural settlements (CPR 5.9%). The Poundbury Camp data on morbidity and mortality are not representative of patterns in Roman England and other major urban sites. Rural children suffered from a distinct set of pathologies described as diseases of deprivation, prompting reconsideration of how Romano-British land management affected those at the bottom of the social hierarchy. © 2016 Wiley Periodicals, Inc.

Near East mtDNA haplotype variants in Roman cattle from Augusta Raurica, Switzerland, and in the Swiss Evolène breed.

Schlumbaum, A; Turgay, M; Schibler, J

2006-08-01

Typical Near East mitochondrial haplotypes of the T2 lineage were found in one cattle metacarpus sample from the Roman period and in two present-day Evolène cattle in Switzerland. Sequences from eight additional Evolène and four Raetian Grey aligned to the European haplotype T3. Analysis of nucleotide diversity within the mitochondrial D-loop of both studied Swiss cattle breeds revealed high haplotype diversity and similar diversity to a European cattle reference group. Mitochondrial T3 haplotypes radiated star-like from two similarly frequent haplotypes, possibly indicating two different expansion routes. The breed structure of Evolène cattle can be explained either by an introduction of diverse female lineages from the domestication centre or by later admixture. The introduction of the Near East lineage to Switzerland must have happened during the Roman time or earlier.

Evolution in the conceptualization of dementia and Alzheimer's disease: Greco-Roman period to the 1960s.

1998-01-01

Most histories of senile dementia commence with Alois Alzheimer's description in 1906 of the first case of Alzheimer's disease, yet the history of senile dementia before 1906 is quite rich, dating back to the ancient Greek and Roman philosophers and physicians. Over the 2500 years since ancient times, the concept of senile dementia has evolved from a rather vague notion that mental decline occurred inevitably in old age, to become defined today by a distinct set of clinical and pathological features with the potential for treatment and prevention within grasp. Throughout history, many elderly individuals with unpredictable behavior were sequestered in institutions, and the line between mental disorders and senile dementia was hazy at best. The identification of Alzheimer's disease at the onset of the 20th century was a turning point for the understanding of senile dementia, and the concepts and histological findings presented by the early researchers of Alzheimer's disease remain relevant still today. Indeed, these early findings are proving to be a continuing source of insight, as many of the issues debated at the turn of the century remain unresolved still today. This paper thus traces the history of the evolution of our current conceptualization of Alzheimer's disease from the amorphous Greco-Roman concept of age-associated dementia.

Dental size and shape in the Roman imperial age: two examples from the area of Rome.

1997-04-01

Different socioeconomic strata of Roman imperial age are represented by two large dental samples recovered from archaeological excavations near Rome, Italy. Teeth are investigated for crown dimensions and morphological variants. One sample, comprising 1,465 permanent teeth, represents the rural town of Lucus Feroniae (LFR) and is mainly composed of slaves and war veterans. The other, comprising 734 teeth from the Isola Sacra necropolis at Portus Romae (NIS), represents the "middle class" segment of an urban population. Both series show small dental dimensions and fit at the lower end of the trend toward dental reduction in Europe from the Upper Paleolithic to the historical times. The urban sample is less variable metrically and less sexually dimorphic than the rural one. The analysis of discrete crown traits shows absence of rare phenotypic variants in both series. The urban sample is also less variable in this last respect, suggesting that the gene pool of this particular "stratum" of the NIS population was more homogeneous than that of LFR. The occurrence of enamel hypoplasia indicates that metabolic stress during growth and development was similar in LFR and NIS. The overall set of available data is evaluated in the light of the history of the two Roman sites and the composition of each population.

Three xylan-degrading actinobacterial strains were isolated from different sampling sites in the Roman catacombs of Domitilla and San Callisto. The organisms showed morphological and chemotaxonomic properties such as peptidoglycan type A4alpha, L-lys-L-thr-D-Glu; whole-cell sugars (glucose, mannose and galactose); octa-, hexa- and tetrahydrogenated menaquinones with nine isoprene units; phosphatidylglycerol and diphosphatidylglycerol as the major phospholipids; anteiso-C(15 : 0), iso-C(15 : 0) and iso-C(16 : 0) as the predominant fatty acids; and a DNA G+C content of 72 mol%. These features are consistent with affiliation of these isolates to the genus Myceligenerans. The three isolates shared a 16S rRNA gene similarity of 99.9 % and were most closely related to Myceligenerans xiligouense DSM 15700T (97.9 % sequence similarity). The low level of DNA-DNA relatedness (about 14 %) and the differences in phenotypic characteristics between the novel strains and M. xiligouense DSM 15700T justify the proposal of a novel species of the genus Myceligenerans, Myceligenerans crystallogenes sp. nov., with CD12E2-27T (= HKI 0369T = DSM 17134T = NCIMB 14061T = VTT E-032285T) as the type strain.

Cutting for stone: Roman lithotomy instruments in the Museo Nazionale Romano.

2010-01-01

Bladder stones, one of the scourges of the past, have been recorded as far back as 6,500 BC. Lithotomy was famously proscribed in the Hippocratic Oath, but it was certainly being undertaken in Hellenistic Alexandria by the 3rd century BC. However, the earliest surviving description of the operation is that of Celsus in the early 1st century AD, while identifiable instrumentation currently dates between the 2nd and early 5th century AD. Finds from Rimini, Marcianopolis, Ephesus and Cyrene illustrate how widespread the operation was at the time of the Roman Empire, but the majority of lithotomy instruments, of which those in the Museo Nazionale Romano are an important part, have been discovered in Rome itself doubtless a reflection of the size of the city's medical 'market'.

The Liqian people in north China are well known because of the controversial hypothesis of an ancient Roman mercenary origin. To test this hypothesis, 227 male individuals representing four Chinese populations were analyzed at 12 short tandem repeat (STR) loci and 12 single nucleotide polymorphisms (SNP). At the haplogroup levels, 77% Liqian Y chromosomes were restricted to East Asia. Principal component (PC) and multidimensional scaling (MDS) analysis suggests that the Liqians are closely related to Chinese populations, especially Han Chinese populations, whereas they greatly deviate from Central Asian and Western Eurasian populations. Further phylogenetic and admixture analysis confirmed that the Han Chinese contributed greatly to the Liqian gene pool. The Liqian and the Yugur people, regarded as kindred populations with common origins, present an underlying genetic difference in a median-joining network. Overall, a Roman mercenary origin could not be accepted as true according to paternal genetic variation, and the current Liqian population is more likely to be a subgroup of the Chinese majority Han.

The Origin of Scientific Notions in the Circle of the Roman Accademia della Virtù around 1550. Between c. 1537 and 1555 a group of humanists, clerics, architects and philologists known as the so-called Accademia della Virtù got together in Rome to work on a program which was formulated in a letter by the Sienese humanist Claudio Tolomei in 1542 and published in 1547. Starting out with the intention to understand the only surviving antique book on architecture and architectural theory - Vitruvius' De architectura libri decem - the program describes a series of 24 books, eleven containing the classical text and its translation with commentaries, 13 books systematically illustrating and documenting all known and available material remains from Roman antiquity. This program for a scientific classical archaeology in a modern sense was not only intended to serve the intellectual curiosity of some humanist antiquarians but to help architects and their patrons to develop a new architecture of the same high quality as the idealized Roman examples. To achieve this practical as well as theoretical goal it was obviously necessary to re-create the antique vocabulary of architecture and its rules as well as to unify the contemporary usage of notions and norms in a canon. The first results of this project seem to be the In decem Libros M. Vitruvii Pollionis de Architectura Annotationes by Guillaume Philandrier (Rome, 1544) - up to this day a very valuable explanation of ambiguous parts in the Vitruvian text. Until the 1980s, it was believed that this book was the only outcome of the ambitious project; but then two codices of drawings after antique reliefs were identified as preparations for one of the other 23 volumes - and, because of their systematic approach, regarded as the 'first systematic archaeological book'. Now it seems that there are some other corpora of manuscripts and drawings documenting antique artifacts that should be regarded as results of the Accademia's work

The objective of this study was to determine and compare lactate profile of two groups of Greco-Roman wrestlers with different competences and training experience. Study was conducted on 10 wrestles that were members of Croatian national team and 10 wrestlers that were members of Wrestling club Split. Lactate samples were collected at four intervals during control fights that were held according to international wrestling rules of World wrestling federation FILA. Values of lactate increased as competition progressed, and they were highest at the end of the match for both groups of wrestlers. According to this study there were no significant differences in lactate between two groups at the end of the match, while significant differences were noted during the match. The information about lactate profile presented in this study can be used by coaches and wrestlers to develop condition programs. Key Points There were no significant differences in lactate concentrations at the end of the match between two proficiency levels of wrestlers. More proficient (elite) wrestlers raise lactates gradually through the wrestling match while less proficient (club) wrestlers raise it abruptly at the end of the first bout. Both groups of wrestlers are unable to sustain same level of activity through the match suggesting that they are utilizing too much energy from anaerobic glycolysis. PMID:24474881

Voltammetry of microparticles (VMP) and electrochemical impedance spectroscopy (EIS) techniques, complemented by SEM-EDX and Raman spectroscopy, were applied to a set of 15 Roman bronze coins and one Tessera from the temple of Magna Mater (Rome, Italy). The archaeological site, dated back between the second half and the end of the 4th century A.D., presented a complicated stratigraphic context. Characteristic voltammetric patterns for cuprite and tenorite for sub-microsamples of the corrosion layers of the coins deposited onto graphite electrodes in contact with 0.10 M HClO 4 aqueous solution yielded a grouping of the coins into three main groups. This grouping was confirmed and refined using EIS experiments of the coins immersed in air-saturated mineral water using the reduction of dissolved oxygen as a redox probe. The electrochemical grouping of coins corroborated the complex stratigraphy of the archaeological site and, above all, the reuse of the coins during the later periods due to the economic issues related to the fall of the Roman Empire.

We attempt to present and analyze suicidal behaviour in the ancient Greek and Roman world. Drawing information from ancient Greek and Latin sources (History, Philosophy, Medicine, Literature, Visual Arts) we aim to point out psychological and social aspects of suicidal behaviour in antiquity. The shocking exposition of suicides reveals the zeitgeist of each era and illustrates the prevailing concepts. Social and legal reactions appear ambivalent, as they can oscillate from acceptance and interpretation of the act to punishment. In the history of these attitudes, we can observe continuities and breaches, reserving a special place in cases of mental disease. The delayed emergence of a generally accepted term for the voluntary exit from life (the term suicidium established during the 17th century), is connected to reactions triggered by the act of suicide than to the frequency and the extent of the phenomenon. The social environment of the person, who voluntary ends his life usually dictates the behaviour and historical evidence confirms the phenomenon. Copyright © 2013 Elsevier B.V. All rights reserved.

This paper presents liver abscesses, as studied in the ancient Greek and Greco-Roman bibliography. Numerous references concerning this entity can be found in the writings of the Hippocratic doctors (5th cent. B.C.), Archigenes of Apamea (1st cent. A.D.), Galen (2nd cent. A.D.), Aretaeus of Cappadocia (2nd cent. A.D), Oribasius (4th cent. A.D.), Theophilus Protospatharius (7th cent. A.D.), and Paulus Nicaeensis (7th-10th cent. A.D.). In most cases the clinical manifestations, the prognosis and the method of treatment are presented. In all ancient writings we studied, the rupture of a liver abscess is also part of the main theme. In specific, the path that the fluid would follow after a rupture was considered to be a main prognostic factor, i.e. if the fluid "coursed into the stomach", the patient would definitely die. In this work, an attempt is also made to correlate the ancient descriptions to modern medical entities, such as amebic or pyogenic liver abscess.

The Pseudo-Galenic Introduction (Introductio Sive medicus, 14.674-797 K.), a medical handbook of the Roman period, witnesses the importance of Hippocrates in medical teaching at the time. Numerous quotations, allusions and reminiscences from the Hippocratic Corpus illustrate Hippocrates' authority for Pseudo-Galen. In the light of the first critical edition of the text (C. Petit, Les Belles Lettres, Paris, 2009), this article discusses the function of Hippocrates, and the various reminiscences of the Hippocratic Corpus, in order to assess Pseudo-Galen's quotation technique and, ultimately, his reliability as a source for the history of medicine.

Trepanation and Roman medicine: a comparison of osteoarchaeological remains, material culture and written texts.

Tullo, E

2010-06-01

Evidence for prehistoric trepanation is limited to preserved osteoarchaeological material, namely human skulls, and the occasional discovery of surgical instruments. However, the Roman empire gave rise to an abundant and diverse range of source types, including skeletal remains, material culture and detailed medical texts, each of which harbours the potential to contribute to our understanding of trepanation during this historical period. This paper highlights the advantages and inherent biases of each of these source types, and proposes that the simultaneous analysis and integration of different types of historical evidence is essential for the study of trepanation as a surgical procedure.

Several testimonies from both pagan and Christian sources, though generally neglected, allow us to reconstruct the medical curriculum in the Greek part of the Roman Empire, in particular Alexandria. This curriculum turns out to be remarkably comprehensive, as can be explained by the particular roles of physicians in classical society. In this paper we will clarify the part played by several physicians in the cultural context of their time, even outside their professional domain, as well as the relations between the sciences and the humanities, which were entirely complementary in those days, even from a practical point of view.

The advances of computer games have shown their potentials for developing edutainment content and services. Current cultural heritages often make use of games in order to complement existing presentations and to create a memorable exhibition. It offers opportunities to reorganize and conceptualize historical, cultural and technological information about the exhibits. To demonstrate the benefits of serious games in terms of facilitating the learning activities in a constructive and meaningful way, we designed a video game about the Heerlen bathhouse heritage. This paper explains the design considerations of this Roman bathhouse game, with a particular focus on the link between game play and learning.

Status and health in Roman Dorset: the effect of status on risk of mortality in post-conquest populations.

2011-10-01

The Roman conquest of Britain was previously shown to have negatively impacted health, particularly for children, older adults, and men. We build upon this previous research by investigating the effect that status had on risks of mortality within the Roman Britain populations of Dorset. This study incorporates a sample of 291 individuals excavated from several cemeteries in the county of Dorset dating between the first to early fifth centuries AD. To assess the effect of status on risks of mortality, burial type was used as a proxy for status and modeled as a covariate affecting the Siler and Gompertz-Makeham models of mortality. The results of these analyses indicate that high-status individuals, particularly children, had a lower mortality risk compared to lower-status groups; and for those buried in urban cemeteries, higher-status individuals of all age-groups had a lower mortality risk. As with our previous study (Redfern and DeWitte: Am J Phys Anthropol 144 (2011) 269-285), we found that male mortality risk was higher than females, which we consider to reflect underlying sex-differences in immunity and disease response.

Mathematics has an important role in solving problems related to mathematical symbols. Mathematics topics are related to the daily life of students, as well as mathematics in the primary school level. In this paper, we report the results of research that aims to understand the difficulties of primary school students towards mathematics, especially on the topic of Roman numerals. The subject of this research included 38 students of fourth grade students from a primary school in the city of Bandung. The results showed that the teacher is more likely do the learning to deliver topic directly to students, rather than having to relatethe learning with a real context. In addition, after the teacher gave some exercises to students, we observed that there are some students’ answers that are unpredictable and made errors. Unexpected answers are caused by student’s unconscientious, misunderstanding, or inability to memorize in seven Roman numeral in general. The results of this analysis can be used to develop teacher competence in the teaching and learning process in the future. In this way, we expect the teacher can prepare various student responses to the given problems in the learning process.

Incorporation of Operating Precepts of Roman Rhetoric in Medieval and Renaissance Handbooks on Letter Writing. Working Paper No. 217.

Water consumption in Iron Age, Roman, and Early Medieval Croatia.

PubMed

Lightfoot, E; Slaus, M; O'Connell, T C

2014-08-01

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. © 2014 Wiley Periodicals, Inc.

How can the stability of a state be quantitatively determined and its future stability predicted? The rise and collapse of empires and states is very complex, and it is exceedingly difficult to understand and predict it. Existing theories are usually formulated as verbal models and, consequently, do not yield sharply defined, quantitative prediction that can be unambiguously validated with data. Here we describe a model that determines whether the state is in a stable or chaotic condition and predicts its future condition. The central model, which we test, is that growth and collapse of states is reflected by the changes of their territories, populations and budgets. The model was simulated within the historical societies of the Roman Empire (400 BC to 400 AD) and the European Union (1957-2007) by using wavelets and analysis of the sign change of the spectrum of Lyapunov exponents. The model matches well with the historical events. During wars and crises, the state becomes unstable; this is reflected in the wavelet analysis by a significant increase in the frequency ω (t) and wavelet coefficients W (ω, t) and the sign of the largest Lyapunov exponent becomes positive, indicating chaos. We successfully reconstructed and forecasted time series in the Roman Empire and the European Union by applying artificial neural network. The proposed model helps to quantitatively determine and forecast the stability of a state.

Invited commentary on 'Robert G Edwards and the Roman Catholic Church'.

In this issue of Reproductive BioMedicine Online, Benagiano, Carrara and Filippi have produced a clearly written and comprehensive account of why the Roman Catholic Church has not welcomed the award of the 2010 Nobel Prize in Physiology and Medicine to Dr Robert G Edwards for the development of human IVF. I commend the article for its clarity and lucidity but attempt to point out some areas where disagreement even with its nuanced opposition to IVF may be legitimate. I try to make some simple comments that explain why this is so and I suggest some areas to which contemporary theology and philosophy can commit itself. But it is good to see even a nuanced response to the work of Robert G Edwards rather than a blanket condemnation. Copyright © 2011 Reproductive Healthcare Ltd. Published by Elsevier Ltd.

The brightest star of the night sky, is Sirius, Alpha Canis Majoris (α CMa). Due to its intense brightness, Sirius had one of the dominant positions in ancient mythology, legends and traditions. In this paper the references of the many ancient classical Greek and Roman authors and poets who wrote about Sirius are examined, and the problem of its 'red' color reported in some of these references is discussed.

Problems faced with legislating for IVF technology in a Roman Catholic country.

Mallia, Pierre

2010-02-01

Malta traditionally enjoys a Roman Catholic Society, with the official religion of the country being cited in the second article of the constitution. Recently the government proposed to legislate to regulate human reproductive technology, in particular In Vitro Fertilization, which has been practiced for over two decades without controlling legislation. A Parliamentary Committee for social affairs was set up to study the situation inviting most stakeholders. The arguments gravitated mostly on issues of the status of the embryo and the media played a considerable role. At the end of the discussion the Archbishop made a statement which pointed out that IVF involves destruction of embryos and the process stopped. This article examines what caused the deterioration of the process and points favourably towards a way forward within the context of a Catholic Country.

The Roman Catholic Church, the Holocaust, and the demonization of the Jews

PubMed Central

Kertzer, David I.

2015-01-01

Following eleven years’ work, in 1998 a high-level Vatican commission instituted by Pope John Paul II offered what has become the official position of the Roman Catholic Church denying any responsibility for fomenting the kind of demonization of the Jews that made the Holocaust possible. In a 2001 book, The popes against the Jews, I demonstrated that in fact the church played a major role in leading Catholics throughout Europe to view Jews as an existential threat. Yet defenders of the church position continue to deny the historical evidence and to launch ferocious ad hominem attacks against scholars who have researched the subject. The anti-Semitism promulgated by the church can be seen as part of the long battle it waged against modernity, with which the Jews were identified. PMID:27011787

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.

[The Vatican and the Roman physicians: debates on corpuscular theories].

PubMed

Donato, Maria Pia

2003-01-01

The essay aims at addressing the debates on corpuscular theories in Rome within the context of the political and religious tensions of the late 17th century. Documents in the archives of the "Congregazione per la Dottrina della Fede" allow us to outline the changing attitudes of the Church of Rome towards atomistic philosophy and to highlight the factional clashes within Roman institutions on the issue. These dynamics gave way to the Congresso Medico Romano of G. Brasavola and G.M. Lancisi, an academy which soon became the promoting agent of an eclectic corpuscular medicine. The Holy Office put the success of the "moderns" into question in 1690, after Alexander VIII had come to the throne. The attach was part of a general repression of atomism (also in Naples and Florence) but also of quietism and freethinking. Despite the crisis, the "moderns" were able to bind their corpuscularism to a strictly defined epistemological model. In the frame of the contemporary biomedical sciences, questions on the ultimate nature of atoms could be abandoned without dismissing the corpuscular theory and practice of medicine.

2014-01-01

The application of Fourier Transform InfraRed (FTIR) spectroscopy to the analysis of oil residues in fragments of archeological amphorae (3rd century A.D.) from Monte Testaccio (Rome, Italy) is reported. In order to check the possibility to reveal the presence of oil residues in archeological pottery using microinvasive and\\or not invasive techniques, different approaches have been followed: firstly, FTIR spectroscopy was used to study oil residues extracted from roman amphorae. Secondly, the presence of oil residues was ascertained analyzing microamounts of archeological fragments with the Diffuse Reflectance Infrared Spectroscopy (DRIFT). Finally, the external reflection analysis of the ancient shards was performed without preliminary treatments evidencing the possibility to detect oil traces through the observation of the most intense features of its spectrum. Incidentally, the existence of carboxylate salts of fatty acids was also observed in DRIFT and Reflectance spectra of archeological samples supporting the roman habit of spreading lime over the spoil heaps. The data collected in all steps were always compared with results obtained on purposely made replicas. © 2013 Elsevier B.V. All rights reserved.

Assessment of chemical analyses by means of portable XRF in the Roman mortars of Complutum archaeological site (Spain)

The chemical characterization of lime mortars used in Roman period has a great significance and plays a key role in the acquisition of knowledge with respect to construction technology, raw materials and, accordingly, in its conservation works. When it comes to cultural heritage studies, sampling is always complicated since the minimum damage is the primary concern. The use of non-destructive techniques and direct measurements with portable devices reduce the amount of samples and time consumed in analyses, consequently it could be stated that such techniques are extremely useful in conservation and restoration works. In this study, the portable XRF device was used to determine the composition of chemical elements which compose the Roman lime mortars in the archaeological site of Complutum, Alcalá de Henares (Madrid, Spain) which is listed as a World Heritage Site by UNESCO since 1998. Portable XRF devices have some detection limits below the ones of the laboratory equipment that are immovable and require sampling. In order to correlate the results, sampling and grinding were initially done to prepare the powders for the laboratory XRF analysis with the following elements: Si, Al, Fe, Ca, Mg, K, Ti, Nb, Zr, Sr, Rb, Pb, Zn and Cr. The analyses of the powdered samples were conducted with the laboratory equipment PHILIPS Magix Pro (PW-2440) from the Centre of Scientific Instrumentation CIC in the University of Granada, and the results were compared to the results gathered with X Ray Florescence (EDTRX) THERMO NITON model XL3T from the Petrophysics Laboratory Geosciences Institute IGEO (CSIC-UCM). Analyses were performed on the surfaces of the samples -without any previous preparation-, and on the powdered samples to compare the variations between both traditional XRF analyses and the portable XRF. A good correlation was found among the results obtained by the laboratory equipment, the portable device as well as the surface measurements. The results of this study

The gladiator cemetery discovered in Ephesus (Turkey) in 1993 dates to the 2nd and 3rd century AD. The aim of this study is to reconstruct diverse diet, social stratification, and migration of the inhabitants of Roman Ephesus and the distinct group of gladiators. Stable carbon, nitrogen, and sulphur isotope analysis were applied, and inorganic bone elements (strontium, calcium) were determined. In total, 53 individuals, including 22 gladiators, were analysed. All individuals consumed C3 plants like wheat and barley as staple food. A few individuals show indication of consumption of C4 plants. The δ13C values of one female from the gladiator cemetery and one gladiator differ from all other individuals. Their δ34S values indicate that they probably migrated from another geographical region or consumed different foods. The δ15N values are relatively low in comparison to other sites from Roman times. A probable cause for the depletion of 15N in Ephesus could be the frequent consumption of legumes. The Sr/Ca-ratios of the gladiators were significantly higher than the values of the contemporary Roman inhabitants. Since the Sr/Ca-ratio reflects the main Ca-supplier in the diet, the elevated values of the gladiators might suggest a frequent use of a plant ash beverage, as mentioned in ancient texts.

The arguments set forth by religious authority are important since they play a crucial role in shaping the social values of the public and influence the decision of individuals in practice pertaining to bioethical issues. The Religious Affairs Administration (RAA) was established at the inception of the Republic of Turkey in 1924 to guide religious considerations moving out of the Ottoman caliphate to a secular bioethical framework. In this article, the bioethical views of the RAA under Islamic tradition is examined and contrasted with those influenced by the Roman Catholic and Orthodox Judaic traditions. On bioethical deliberations related to the beginning and end-of-life, all three religious traditions justify sacredness of life and that of God's will in its preservation it. Assisted reproduction techniques between spouses is considered to be appropriate, although third party involvement is explicitly forbidden. Organ transplantation is approved by all three religious traditions, except uterine transplantation. Contraceptive practices are approved under certain conditions - views differ most on approaches to contraception and the appropriateness of methods. The RAA judgement on cloning is to prohibit it, like Roman Catholicism and Orthodox Judaism. In other topics, cosmetic surgery and gender determination are approved only for treatment.

This paper aims to bring to light the possible linkage between karstic phenomena and the human occupation of the Roman site of Carsulae (Tiber basin, Central Italy). Dolines are a typical morphological expression of karst rocks' dissolution and collapse and, usually, they represent a potential hazard for human activities and, in particular, in the care and maintenance of cultural heritage sites. In this study, we observed that the development of a subsidence doline caused severe damage to some archaeological structures at the Carsulae monumental site. According to the results obtained in our investigation, three sites at least with karst dissolution phenomena in the shallow calcareous tufa layer have been identified. One of them subsided probably in Roman times and produced a sharp deformation of the decumanus. In order to understand the evolution of this territory an integrated geomorphological and geophysical survey was carried out. The combination between the information derived from different geophysical techniques, such as: Electrical Resistivity Tomography (ERT), Frequency-Domain Electromagnetism (FDEM), and Ground Penetrating Radar (GPR) clearly pointed out that the calcareous tufa layer is characterized by an irregular geometry and this resulted in the investigated area being affected by karst dissolution in several parts. Four boreholes opportunely located, provided direct information about the depth and the alteration of the calcareous tufa basement and precious calibration data for the geophysical methods. This study contributes to improving our knowledge on the evolution of the Carsulae archaeological site providing a new insight into the adaptation of ancient human societies in this problematic territory.

A seesaw in Mediterranean precipitation during the Roman Period linked to millennial-scale changes in the North Atlantic

We present a reconstruction of the change in climatic humidity around the Mediterranean between 3000-1000 yr BP. Using a range of proxy archives and model simulations we demonstrate that climate during this period was typified by a millennial-scale seesaw in climatic humidity between Spain and Israel on one side and the Central Mediterranean and Turkey on the other, similar to precipitation anomalies associated with the East Atlantic/West Russia pattern in current climate. We find that changes in the position and intensity of the jet stream indicated by our analysis correlate with millennial changes in North Atlantic sea surface temperature. A model simulation indicates the proxies of climatic humidity used in our analysis were unlikely to be influenced by climatic aridification caused by deforestation during the Roman Period. That finding is supported by an analysis of the distribution of archaeological sites in the Eastern Mediterranean which exhibits no evidence that human habitation distribution changed since ancient times as a result of climatic aridification. Therefore we conclude that changes in climatic humidity over the Mediterranean during the Roman Period were primarily caused by a modification of the jet stream linked to sea surface temperature change in the North Atlantic. Based on our findings, we propose that ocean-atmosphere coupling may have contributed to regulating Atlantic Meridional Overturning Circulation intensity during the period of analysis.

This paper deals with both the reality and the idealization of training of midwives in the Roman Empire. It aims at a full survey of the existing source material (mainly literary and epigraphical sources, though iconographical and papyrological evidence has been included in the discussion). For the first time, a complete collection of the epigraphically attested Latin cases will be given. Moreover, I will deal with the apparent contradiction between the image of the educated midwife as it is exhibited mainly by Soranus, and the picture of midwives as low class women as it is revealed in other sources. In doing so, I will make use of the concept of differential equations, as applied by Joshel and Murnaghan concerning women and slaves in ancient society. As such, I will take issue with the Cilliers and Retief thesis about the social role of women in ancient medicine.

The papers deals with the use of VHR satellite multitemporal data set to extract cultural landscape changes in the roman site of Grumentum Grumentum is an ancient town, 50 km south of Potenza, located near the roman road of Via Herculea which connected the Venusia, in the north est of Basilicata, with Heraclea in the Ionian coast. The first settlement date back to the 6th century BC. It was resettled by the Romans in the 3rd century BC. Its urban fabric which evidences a long history from the Republican age to late Antiquity (III BC-V AD) is composed of the typical urban pattern of cardi and decumani. Its excavated ruins include a large amphitheatre, a theatre, the thermae, the Forum and some temples. There are many techniques nowadays available to capture and record differences in two or more images. In this paper we focus and apply the two main approaches which can be distinguished into : (i) unsupervised and (ii) supervised change detection methods. Unsupervised change detection methods are generally based on the transformation of the two multispectral images in to a single band or multiband image which are further analyzed to identify changes Unsupervised change detection techniques are generally based on three basic steps (i) the preprocessing step, (ii) a pixel-by-pixel comparison is performed, (iii). Identification of changes according to the magnitude an direction (positive /negative). Unsupervised change detection are generally based on the transformation of the two multispectral images into a single band or multiband image which are further analyzed to identify changes. Than the separation between changed and unchanged classes is obtained from the magnitude of the resulting spectral change vectors by means of empirical or theoretical well founded approaches Supervised change detection methods are generally based on supervised classification methods, which require the availability of a suitable training set for the learning process of the classifiers

a Procedural Solution to Model Roman Masonry Structures

Cappellini, V.; Saleri, R.; Stefani, C.; Nony, N.; De Luca, L.

2013-07-01

The paper will describe a new approach based on the development of a procedural modelling methodology for archaeological data representation. This is a custom-designed solution based on the recognition of the rules belonging to the construction methods used in roman times. We have conceived a tool for 3D reconstruction of masonry structures starting from photogrammetric surveying. Our protocol considers different steps. Firstly we have focused on the classification of opus based on the basic interconnections that can lead to a descriptive system used for their unequivocal identification and design. Secondly, we have chosen an automatic, accurate, flexible and open-source photogrammetric pipeline named Pastis Apero Micmac - PAM, developed by IGN (Paris). We have employed it to generate ortho-images from non-oriented images, using a user-friendly interface implemented by CNRS Marseille (France). Thirdly, the masonry elements are created in parametric and interactive way, and finally they are adapted to the photogrammetric data. The presented application, currently under construction, is developed with an open source programming language called Processing, useful for visual, animated or static, 2D or 3D, interactive creations. Using this computer language, a Java environment has been developed. Therefore, even if the procedural modelling reveals an accuracy level inferior to the one obtained by manual modelling (brick by brick), this method can be useful when taking into account the static evaluation on buildings (requiring quantitative aspects) and metric measures for restoration purposes.

Post-mortem Cesarean section and embryotomy: myth, medicine, and gender in Greco-Roman culture.

2013-01-01

This article focuses on cesarean section carried out after the mother's death to rescue the living infant and on embryotomy, a medical procedure to save the mother described as early as the Hippocratic writings (5th to 4th century B.C.) and practiced until the times of Paul of Aegina (7th century A.D). The available sources do not mention cesarean section on a living mother to save the infant. On the other side, writings on embryotomy state clearly that Greek and Roman physicians strove hard to save women's lives. Written in ancient, male-centered societies, these texts convey an unequivocal positive attitude towards women, despite current misogynist assessments by philosophers and physicians who considered women inferior, based on their organic and biological features.

The physical, chemical, and mechanical properties of mortars and bricks used in the historical building that was erected at Myra within the boundaries of Antalya Province during the Roman time were investigated. The sample picked points were marked on the air photographs and plans of the buildings and samples were photographed. Then petrographic evaluation was made by stereo microscope on the polished surfaces of construction materials (mortar, brick) taken from such historical buildings in laboratory condition. Also, microstructural analyses (SEM/EDX, XRD), physical analyses (unit volume, water absorption by mass, water absorption by volume, specific mass, compacity, and porosity), chemical analyses (acid loss and sieve analysis, salt analyses, pH, protein, fat, pozzolanic activity, and conductivity analyses), and mechanical experiments (compressive strength, point loading test, and tensile strength at bending) were applied and the obtained results were evaluated. It was observed that good adherence was provided between the binder and the aggregate in mortars. It was also detected that bricks have preserved their originality against environmental, atmospheric, and physicochemical effects and their mechanical properties showed that they were produced by appropriate techniques.

A novel actinobacterium, strain BC637(T), was isolated from a biodeteriogenic biofilm sample collected in 2009 in the Saint Callixstus Roman catacomb. The strain was found to belong to the genus Kribbella by analysis of the 16S rRNA gene. Phylogenetic analysis using the 16S rRNA gene and the gyrB, rpoB, relA, recA and atpD concatenated gene sequences showed that strain BC637(T) was most closely related to the type strains of Kribbella lupini and Kribbella endophytica. DNA-DNA hybridization experiments confirmed that strain BC637(T) is a genomic species that is distinct from its closest phylogenetic relatives, K. endophytica DSM 23718(T) (63 % DNA relatedness) and K. lupini LU14(T) (63 % DNA relatedness). Physiological comparisons showed that strain BC637(T) is phenotypically distinct from the type strains of K. endophytica and K. lupini. Thus, strain BC637(T) represents the type strain of a novel species, for which the name Kribella italica sp. nov. is proposed ( = DSM 28967(T) = NRRL B-59155(T)). © 2015 IUMS.

Ancient euthanasia: 'good death' and the doctor in the graeco-Roman world.

PubMed

Van Hooff, Anton J L

2004-03-01

This article maps the concept of 'good death' (euthanasia) in the ancient world and explores the marginal role of the doctor at a 'good dying'. His assistance was not needed when the Homeric warrior died as a hero and was expected to accept death with resignation. Later the city-state regarded as heroes the men fallen for the cause of the community, honouring these model citizens as those who died well. In the more individualistic age of Hellenism and the Roman Empire, a death in luxury or without suffering could be styled euthanasia. The doctor had neither a place in those acts of dying nor in cases of natural death. He shunned death as a failure of his art. Sometimes a doctor was called in to assist in voluntary death, a role that was not forbidden by the Hippocratic oath. An appeal to this oath by opponents of euthanasia in the modern sense of the word therefore is mistaken.

The study of both original and decaying compounds is relevant in understanding the chemistry behind the deterioration processes, above all in open museum contexts where environmental stressors affect the artefacts. In this sense, a combination of non-invasive spectroscopy techniques (Raman spectroscopy, μ-X-ray fluorescence and X-ray diffraction) was applied on an ancient Roman building (130 CE), the "Casa di Diana" Mithraeum at Ostia Antica archaeological site. The aim is to study the raw materials, manufacturing and decaying products of the two observed types of Roman fired bricks (red and yellow) that compose the building. The present study estimates an illite raw material of carbonate-bearing marine clay likely referring to the common deposits of central/southern Italy, which contain calcite as accessory phase and a-plastic fraction constituted by quartz, feldspar and opaques. This clay material was added with volcanic temper characterised by abundant clinopyroxene and analcime (from analcimization of leucite) that are typical of the Roman Province volcanism. The firing would be probably the result of oxidizing conditions, as proved by the hematite presence. Thanks to the existence of specific neoformed mineral phases during firing it was possible to assess different temperatures ranges. In detail, the red/orange bricks, for the existence of gehlenite (formed from calcite and its reaction with silicates), were fired at 800-900 °C range; whereas, the yellow ones are characterised by the lack of gehlenite and the disappearance of illite/muscovite, which indicates firing temperature at over 900 °C. Regarding the decaying products, the gypsum covers most of the surface of most bricks, both red and the yellow ones, but these latter are more susceptible to environmental stressors (sulphates and carbonates). Therefore, this work points out how by integrated non-invasive approaches it is possible trace back to original firing temperature, technology of

Mardels, small closed depressions, are distinctive landforms on the Luxembourger Gutland plateau. In the present landscape most mardels are shallow fens, filled with colluvial sediments. The genesis of mardels has been studied intensively, inside and outside Luxembourg. Some researchers suggested a natural development and consider mardels as subsidence basins due to subsurface solution of gypsum veins, other researchers suggested cultural causes and consider mardels as prehistorical quarries. In the Gutland, mardels occur on various substrates. Mardels on the Strassen marls (li3) are abandoned quarries, related to clay excavation in Roman Time. Mardels on the Luxembourger sandstone (li2) are sinkholes, related to joint patterns in the sandstone formation. Mardels on the Keuper marls (km1,3) are originally subsidence basins, related to subsurface dissolutions of gypsum lenses and veins, filled with colluvial clay. The results of pollen analysis and archaeometrical tests demonstrate Roman extraction of clay for the production of ancient ceramics. So, the natural depressions have been enlarged to the present mardels. After excavation, the sedimentation of colluvium restarted in the abandoned quarries.

Electronic measurement of visual acuity (VA) has been proposed and adopted as a method of determining VA scores in clinical research. Characters (optotypes) are displayed on a monitor screen and the examinee selects a match and inputs his choice to another electronic device. Unfortunately, the optotypes, called Sloan letters, in the standard protocol are 10 Roman characters. This limits their practicabilityfor measuring VA of patients who are illiterate to these characters. The authors introduced a method of displaying the Sloan letters one by one on a notebook and all 10 Sloan letters on a tablet computer screen. The former is for testing the patients whereas the latter is for them to input their responses by tapping on a letter that matches the one on the notebook screen. To assess test-retest reliability of VA scores determined with this method. Participants without ocular abnormality were recruited to have their right eyes measured with the same VA measurement method twice, one week apart. Those who were illiterate to Roman characters were enrolled for the aforementioned method for measuring their VA (Tablet group). A 15-inch display notebook computer and a 9-inch display tablet computer (iPad) communicated via a local wireless data network provided by a Wi-Fi router. Those who understood Roman characters were enrolled to have measurements with a 17-inch desktop computer and an infrared wireless keyboard (Keyboard group). Both methods used the same protocols and software for VA measurements. Reliability of VA scores obtained from each group was assessed by the confidence interval (CI) of the difference of the scores from the test and retest. The t test was used to analyze differences in mean VA scores between the test and retest in each group with p < 0.05 determined as statistically significant. There were 49 and 50 participants in the Tablet and Keyboard group respectively. The 95% CI of the difference between the scores from the test and retest in each group

This paper reports on a study carried out on patinas covering copper-based Greek and Roman coins found in the archaeological excavation of Regio VIII.7.1-15 in Pompeii (Italy). Since in cultural heritage ancient artefacts should not be damaged, non-destructive and micro-destructive techniques have been used to identify typical and uncommon compounds and to characterize the surface morphology. The chlorine content of light green patinas and the presence of typical minerals allowed us to identify the bronze disease. Coins from the same stratigraphic unit have shown different morphologies of corrosion, probably due to different micro-environmental conditions.

[The use of opium in Roman society and the dependence of Princeps Marcus Aurelius].

PubMed

Trancas, Bruno; Borja Santos, Nuno; Patrício, Luís D

2008-01-01

Opium was known and frequently used in Roman society. Medical practice recognized its usefulness as an analgesic, soporific, anti-tussic or anti-diarrheic agent, as well as other currently unsupported uses with quasi-magical properties. It was additionally used as an ingredient in antidotes, panaceas and poisons. The authors present a non-exhaustive compilation of opium use according to medical doctors, writers and encyclopaedists of the time. Mythological and literary representations of the opium poppy reflected its diverse roles, being associated with prosperity and fertility, sleep, death and the underworld and with the art of medicine. Despite its free and routine use, there is no solid evidence of addiction, except the putative case of emperor Marcus Aurelius, consistently reported as one of the most likely cases of addiction to opium.

The Romane sheep breed proved to be adapted to harsh conditions with high prolificacy and lamb survival in outdoor farming, even under bad climate conditions. This breed shows large variability in its fleece type at birth and it has been suggested that lamb survival could be related to birthcoat type. The aim of the present study was to: i) characterize the coat of the lamb at birth and quantify lamb survival in relation to the birthcoat type and its protective properties concerning heat loss in the Romane breed raised under permanent exposure outdoors from birth, and ii) estimate genetic parameters of birthcoat type in relation to lamb survival and live body weight. A total of 7,880 lambs from 104 sires and 1,664 dams were used in a 14-yr experiment. The pedigree file included 9,625 individuals over 15 generations. Birthcoat type, coat surface temperature, coat depth, lamb survival, and growth were measured from birth to weaning. Weather data (temperature, wind speed, relative humidity, and precipitation) were recorded daily during lambing time. Two types of coats were observed at birth: hairy coat (62.9% of lambs) with a long coat depth (average 23.3 mm) or woolly 1 (37.1% of lambs) with a short coat depth (average 8.3 mm). Birthcoat type was an important factor affecting lamb survival and growth from birth in the Romane breed. Total mortality rate was significantly less in hairy-bearing coat lambs than in short-woolly coat ones: 7.0% vs. 9.6%, 11.6 % vs. 14.8%, and 15.7 % vs. 20.1 % at 2, 10, and 50 d, respectively, and the relative risks of death increased by 37%, 67%, and 46 % at 2, 10, and 50 d of age, respectively, in short-woolly lambs. At birth, a significant lower coat surface temperature, indicating less heat loss, was observed in long-hairy coat lambs compared with others (21.1°C vs. 26.1°C). Heavier body weights and better growth performances up to the age of 50 d were observed in long-hairy-bearing coat lambs. Lamb survival was positively correlated

A new simple way of synthesizing Li[NiMnCo]O2 was contrived and its electrochemical characteristics were enhanced by Si doping using solution-based synthetic route. The newly synthesized Li[NiMnCo]O2 showed capacity of 175mAh/g and good cycle life at as high cut-off voltage as 4.5V. Si-doping improved the rate capability, specific capacity, and cycle life of the material through increasing lattice parameters and lowering electrochemical impedance.

The study of the aetiologies of diseases in Ancient Times is usually a speculative intellectual exercise. When some authors attribute a specific aetiology to an old disease, there is a great risk of committing a methodological error, known as presentism by the modern historiography. The authority of the investigator, more than the weight of the scientific truth, is usually the reason why the diagnosis has remained over the years. The great epidemic of the years 164-165AD and afterwards, could have been smallpox (haemorrhagic form). Claude Galen, the famous doctor, described the symptoms in several books of his great Opera Omnia. For this reason, it is currently known among the scholars as Galen's plague. The epidemic was described for the first time in Seleucia (Mesopotamia). Until now, the actual geographic origin is unknown. We propose here that the beginning might be the kingdom of the old Han dynasty (now the Chinese Popular Republic). The epidemic swept the Roman Empire, from the east to the west, and from the southern to the northern borders. An immediate consequence of the infection was a high morbidity and mortality. In this sense, Galen's epidemic was one of the many factors that caused the fall and destruction of the Roman Empire. On the other hand, there is a general agreement among historians, biographers and researchers that the philosopher emperor Marcus Aurelius Antoninus (121-180AD was affected by the infection in the epidemic wave of 164-165AD. The death of Marcus Aurelius occurred on March 17 in the year 180AD, in Vindobonne, or perhaps Sirminium (near to Vienna). Many authors propose that the cause of the emperor's death was the same epidemic. We consider that it is not possible to demonstrate any of those speculative diagnoses. Finally, the epidemic of 189-190AD, that we have named of Commodus, was probably a different disease to the Galen's plague. There were several kinds of animals affected (anthropozoonoses). In this sense, this infection

Roman bronze artefacts from Thamusida (Morocco): Chemical and phase analyses

2011-02-01

Twenty-six objects (1st to the 3rd century AD) found at the archaeological site of Thamusida (Morocco), which is a military settlement between the 1st and the 3rd century AD, have been investigated by means of portable X-ray fluorescence and time of flight-neutron diffraction. The combination of element-sensitive X-ray fluorescence and structure-sensitive neutron diffraction yields, in a totally non-destructive way, the necessary information to discriminate the copper alloy from corrosion and alteration layers. Results allowed dividing the repertory into five groups: (a) unalloyed copper, (b) binary alloys made of Cu and Sn, frequently leaded; (c) unleaded binary alloys made of Cu and Zn; (d) ternary alloys made of Cu, Sn and Zn, both leaded and unleaded; (e) quaternary alloys made of Cu, Sn, Zn and As. The choice of alloy is heterogeneous, mainly depending on availability and costs of raw and/or scrap materials and on technological constraints. Interestingly, the reconstruction obtained for Thamusida could either anticipate the important change in the Roman use of copper alloys generally referred as 'zinc decline', or more likely, indicate that brass never conspicuously entered the local metal-working activities of this military site.

Three-dimensional reconstruction of Roman coins from photometric image sets

2017-01-01

A method is presented for increasing the spatial resolution of the three-dimensional (3-D) digital representation of coins by combining fine photometric detail derived from a set of photographic images with accurate geometric data from a 3-D laser scanner. 3-D reconstructions were made of the obverse and reverse sides of two ancient Roman denarii by processing sets of images captured under directional lighting in an illumination dome. Surface normal vectors were calculated by a "bounded regression" technique, excluding both shadow and specular components of reflection from the metallic surface. Because of the known difficulty in achieving geometric accuracy when integrating photometric normals to produce a digital elevation model, the low spatial frequencies were replaced by those derived from the point cloud produced by a 3-D laser scanner. The two datasets were scaled and registered by matching the outlines and correlating the surface gradients. The final result was a realistic rendering of the coins at a spatial resolution of 75 pixels/mm (13-μm spacing), in which the fine detail modulated the underlying geometric form of the surface relief. The method opens the way to obtain high quality 3-D representations of coins in collections to enable interactive online viewing.

Conversion electron, X-ray backscattering and conventional transmission57Fe Mössbauer measurements have been performed to investigate the origin of the remarkable work hardening at the surface of a high-manganese steel which is called Hadfield steel. Mössbauer results show that α' martensite has no relation to work hardening. From the comparison of conversion electron to X-ray backscattering spectra, the occurrence of decarbonization is suggested at the surface. The transmission Mössbauer spectrum at 20 K for deformed specimen shows the existence of ɛ martensite which could be related to the work hardening of Hadfield steel.

The physical, chemical, and mechanical properties of mortars and bricks used in the historical building that was erected at Myra within the boundaries of Antalya Province during the Roman time were investigated. The sample picked points were marked on the air photographs and plans of the buildings and samples were photographed. Then petrographic evaluation was made by stereo microscope on the polished surfaces of construction materials (mortar, brick) taken from such historical buildings in laboratory condition. Also, microstructural analyses (SEM/EDX, XRD), physical analyses (unit volume, water absorption by mass, water absorption by volume, specific mass, compacity, and porosity), chemical analyses (acid loss and sieve analysis, salt analyses, pH, protein, fat, pozzolanic activity, and conductivity analyses), and mechanical experiments (compressive strength, point loading test, and tensile strength at bending) were applied and the obtained results were evaluated. It was observed that good adherence was provided between the binder and the aggregate in mortars. It was also detected that bricks have preserved their originality against environmental, atmospheric, and physicochemical effects and their mechanical properties showed that they were produced by appropriate techniques.

A series of 89 glass fragments of Roman glass are studied using electron, proton and synchrotron radiation induced X-ray emission from microscopic areas on the sample surface. The glass originates from Qumran, Jordan and was buried for 1900 years. The weathering layers that result from the extended contact with ground water have been studied, next to the trace composition of the original glass of these pieces. The latter information indicates that at Qumran, large quantities of glass objects were being used in Ancient times. Cross-sectional profiles of the glass show a complex migration behaviour of various groups of major and trace elements.

Flank eruptions of Mt Etna during the Greek-Roman and Early Medieval periods: New data from 226Ra-230Th dating and archaeomagnetism

2015-10-01

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.

2017-03-01

Christian deacons (50 Roman Catholic; 50 Methodist) self-reported their personality, religiosity, and leadership attributes, plus social desirability tendencies. There were no significant correlates between social desirability and any of these self-reported variables. Results also found no significant differences across Christian denominations on personality dimensions, religious and spirituality beliefs, or leadership styles. Also, there were no significant differences in self-reported personality, religiosity, or leadership among Catholic male deacons with Methodist female deacons only ( n = 43). Taken together, in the present exploratory study across denomination and gender, Christian deacons view themselves similarly in personality, religiosity, and overall leadership characteristics.

A Roman bronze statuette from the 2nd Century BC was recovered from a nuragic sanctuary close to Florinas, in the north of Sardinia. The facial portion of the statuette is covered by a silver mask, partially gilded and attached to the bronze by tin-lead welding. The silver mask was carefully analyzed by portable energy-dispersive X-ray fluorescence (EDXRF), a non-destructive and non-invasive method. The aim of the analysis was to reconstruct the layered structure of the silver gilt mask, and to determine homogeneity and thickness of the gold, silver and lead-tin sheets. This is possible by using the internal ratio of the X-ray lines, i.e. starting from the surface, Au (L α/L β), Ag (K α/K β), Au-L α/Ag-K α and Pb (L α/L β).The results were compared with those obtained with simulated X-ray spectra, obtained both experimentally and by using the Monte Carlo simulation technique.

Investigation of white pigments used as make-up during the Greco-Roman period

Different white pigments were used during antiquity to prepare white make-up for women faces. Combining observations and elemental analysis with structural information, we were able to determine the mineralogical composition of cosmetics, the trace element content and the microstructure of the crystals. SEM/EDX analyses enabled us to describe the choice of materials and their preparation by grinding or chemical synthesis to obtain white pigments. For the Hellenistic period, we have mainly found lead white, which required an elaborated synthesis process. Quantitative X-ray diffraction allowed us to establish different ratios of hydrocerussite 2PbCO3·Pb(OH)2 and cerussite PbCO3. These data can be linked to the chemical conditions of preparation described by ancient authors. On the other hand, analyses of Roman cosmetics from Pompeii, Gaul and Germany show the use of materials commonly found in nature like gypsum or calcite. We will discuss the material properties in relation with the make-up uses.

The laser-induced breakdown spectroscopy (LIBS) technique was used for analyzing the composition of an ancient Roman mortar (5th century A.D.), exploiting an experimental setup which allows the determination of the compositions of binder and aggregate in few minutes, without the need for sample treatment. Four thousand LIBS spectra were acquired from an area of 10 mm 2 , with a 50 µm lateral resolution. The elements of interest in the mortar sample (H, C, O, Na, Mg, Al, Si, K, Ca, Ti, Mn, Fe) were detected and mapped. The collected data graphically shown as compositional images were interpreted using different statistical approaches for the determination of the chemical composition of the binder and aggregate fraction. The methods of false color imaging, blind separation, and self-organizing maps were applied and their results are discussed in this paper. In particular, the method based on the use of self-organizing maps gives well interpretable results in very short times, without any reduction in the dimensionality of the system.

A Gram-stain-negative, aerobic, motile, rod-shaped bacterium, strain SC13E-S71(T), was isolated from tuff, volcanic rock, where the Roman catacombs of Saint Callixtus in Rome, Italy, was excavated. Analysis of 16S rRNA gene sequences revealed that strain SC13E-S71(T) belongs to the genus Sphingopyxis, and that it shows the greatest sequence similarity with Sphingopyxis chilensis DSM 14889(T) (98.72 %), Sphingopyxis taejonensis DSM 15583(T) (98.65 %), Sphingopyxis ginsengisoli LMG 23390(T) (98.16 %), Sphingopyxis panaciterrae KCTC 12580(T) (98.09 %), Sphingopyxis alaskensis DSM 13593(T) (98.09 %), Sphingopyxis witflariensis DSM 14551(T) (98.09 %), Sphingopyxis bauzanensis DSM 22271(T) (98.02 %), Sphingopyxis granuli KCTC 12209(T) (97.73 %), Sphingopyxis macrogoltabida KACC 10927(T) (97.49 %), Sphingopyxis ummariensis DSM 24316(T) (97.37 %) and Sphingopyxis panaciterrulae KCTC 22112(T) (97.09 %). The predominant fatty acids were C18 : 1ω7c, summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1ω7c), C14 : 0 2-OH and C16 : 0. The predominant menaquinone was MK-10. The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine and sphingoglycolipid. These chemotaxonomic data are common to members of the genus Sphingopyxis. However, a polyphasic approach using physiological tests, DNA base ratios, DNA-DNA hybridization and 16S rRNA gene sequence comparisons showed that the isolate SC13E-S71(T) belongs to a novel species within the genus Sphingopyxis, for which the name Sphingopyxis italica sp. nov. is proposed. The type strain is SC13E-S71(T) ( = DSM 25229(T) = CECT 8016(T)).

Morphological and biomechanical analysis of a skeleton from Roman imperial necropolis of Casalecchio di Reno (Bologna, Italy, II-III c. A. D.). A possible case of crutch use.

PubMed

Belcastro, M G; Mariotti, V

2000-12-01

A Roman skeleton (T.130) from the roman necropolis of Casalecchio di Reno has been studied in order to understand if the hypothesis of crutch use, suggested by the severe articular degeneration at the hip joint that caused evident reduction of his locomotory possibilities, could be supported by the morphological alterations of other bones and joints. The pathological changes and muscular development of the upper limbs and shoulder girdle bones suggest that these parts were submitted to a great mechanical stress. The observations are consistent with the hypothesis of crutch use that would have involved a new weight-bearing function of the upper limbs in order to help locomotion, even though it is difficult to assess the number and type of the crutches. The comparison with other possible cases of crutch use reported in literature gives an additional support to the interpretation of the findings.

This study was conducted to evaluate the effect of γ-aminobutyric acid (GABA) on laying performance, egg quality, digestive enzyme activity, hormone level and immune activities in Roman hens under heat stress. Roman hens (320 days old) were fed with 0, 25, 50, 75 and 100 mg/kg GABA, respectively during a 60-day experiment. Compared with control, supplementation of 50 mg/kg GABA improved the laying performance and egg quality by significantly increasing egg production, average egg weight and shell strength (P < 0.05), while decreasing the feed-egg ratio and cholesterol level. Anti-oxidation activity was improved by significantly increasing the activity of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px), but decreasing malondialdehyde level in serum (P < 0.05), while significantly increasing the glucose and total protein (TP) level, follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E(2) ), insulin, triiodothyronine (T(3) ) and free triiodothyronine (FT(3) ) levels, and IgG, IgA and complement (C3)activity in serum (P < 0.05). The results indicated that oral GABA improved laying performance and physical condition mainly by modulating hormone secretion, enhancing anti-oxidation and immune activity, and maintaining electrolyte balance. Fifty mg/kg was the optimum level for laying hens under heat stress in the present study. © 2011 The Authors. Animal Science Journal © 2011 Japanese Society of Animal Science.

Two rural sites on the island of Mallorca (Balearic Islands, Spain) have been investigated with geophysical methods. A previous archaeological field survey provided surface ceramics that allowed for a first classification of the sites as possible Roman rural settlements, possibly villae. The objective of the investigation was to work towards the identification of architectural remains to better understand the true nature of the sites. Using the 7-probe fluxgate gradiometer array LEA MAX, magnetic measurements were executed on a large area on each site. GPR measurements were subsequently carried out to examine selected areas of interest in detail by means of the IDS GPR system based on the Fast-Wave module. The investigated areas demonstrated excellent surface conditions with a negligible number of sources of disturbance, permitting a detailed interpretation of the geophysical data. The results helped to reveal the presence of architectural remains beneath the soil at both sites.

RA prevalence in the general population was evaluated using a standardized telephone survey in 1857 homes taken at random. Individuals who reported an inflammatory joint disease were contacted by a rheumatologist of our unit, missing data were collected from the general practitioner or rheumatologist with the patient's permission, and if necessary a physical examination was done by a rheumatologist. The 9 largest Roman Catholic nun communities in Brittany were screened using the same standardized questionnaire administered face-to-face; nuns who reported an inflammatory joint disease were interviewed and examined by rheumatologists. In both populations, RA was diagnosed when (1) the rheumatologist of our unit who interviewed the patient considered the RA classification criteria positive and (2) the rheumatologist who examined the patient gave a diagnosis of RA independently from RA classification criteria. Data were available for 1706 adult females in the general population and 721 nuns. Of the 20 nuns who reported RA or polyarthritis, 11 received a diagnosis of RA (prevalence 1.52%). The prevalences adjustedfor the French population after 40 years were 1.66% (95% confidence interval, 0.84-2.44) and 1.33 (0.27-2.40) among the nuns and the general female population, respectively. Although our nun population was too small for definite conclusions, we found no evidence of a difference in RA prevalence among nuns and the general female population in Brittany.

The Circular Mausoleum tomb (Roman Necropolis of Carmona, Spain) dates back from the first century AD and is characterized by a dense microbial (phototrophic) colonization on the walls and ceiling. However, some walls exhibited an important number of violet stains of unknown origin. The microbial communities of these violet stains are mainly composed of cyanobacteria, streptomycetes and fungi. A strain of Streptomyces parvus, isolated from the walls, produces a violet pigment in culture media. High performance liquid chromatography-mass spectrometry of the culture extracts obtained from this Streptomyces revealed the presence of a few granaticins, pigments with a benzoisochromanequinone structure. When metabolically active in the tomb, S. parvus synthesizes the pigments that diffuse into the mortar. During rain and/or wetting periods, the pigments are solubilized by alkaline waters and elute from the starting position to the surrounding mortar, enlarging the pigmented area and thus contributing to this exceptional biodeterioration phenomenon.

Forensic and archaeological examinations of human skeletons can provide us with evidence of violence. In this paper, we present the patterns of two cranial lesions found on an adult male (T173) buried in a grave in the necropolis 'Isolato 96', Messina, Sicily, dating back to the Roman Empire (1st century BC - 1st century AD). The skull reveals two perimortem traumatic lesions, one produced by a sharp object on the right parietal bone and the other one on the left parietal bone, presumably the result of a fall. The interpretation of fracture patterns found in this cranium are an illustration of how forensic approaches can be applied with great benefit to archaeological specimens.

Urbanism and the division of labour in the Roman Empire.

Hanson, J W; Ortman, S G; Lobo, J

2017-11-01

One of the hallmarks of human agglomeration is an increase in the division of labour, but the exact nature of this relationship has been debated among anthropologists, sociologists, economists, and historians and archaeologists. Over the last decade, researchers investigating contemporary urban systems have suggested a novel explanation for the links between the numbers of inhabitants in settlements and many of their most important characteristics, which is grounded in a view of settlements as social networks embedded in built environments. One of the remarkable aspects of this approach is that it is not based on the specific conditions of the modern world (such as capitalism or industrialization), which raises the issue of whether the relationships observed in contemporary urban systems can also be detected in pre-modern urban or even non-urban systems. Here, we present a general model for the relationship between the population and functional diversity of settlements, where the latter is viewed as an indicator of the division of labour. We then explore the applicability of this model to pre-modern contexts, focusing on cities in the Roman Empire, using estimates of their numbers of inhabitants, numbers of documented professional associations, and numbers of recorded inscriptions to develop an index of functional diversity. Our results are consistent with theoretical expectations, adding further support to the view that urban systems in both contemporary and pre-modern contexts reflect a common set of generative processes. © 2017 The Authors.

Life and death in a civitas capital: metabolic disease and trauma in the children from late Roman Dorchester, Dorset.

The impact that "Romanization" and the development of urban centers had on the health of the Romano-British population is little understood. A re-examination of the skeletal remains of 364 nonadults from the civitas capital at Roman Dorchester (Durnovaria) in Dorset was carried out to measure the health of the children living in this small urban area. The cemetery population was divided into two groups; the first buried their dead organized within an east-west alignment with possible Christian-style graves, and the second with more varied "pagan" graves, aligned north-south. A higher prevalence of malnutrition and trauma was evident in the children from Dorchester than in any other published Romano-British group, with levels similar to those seen in postmedieval industrial communities. Cribra orbitalia was present in 38.5% of the children, with rickets and/or scurvy at 11.2%. Twelve children displayed fractures of the ribs, with 50% of cases associated with rickets and/or scurvy, suggesting that rib fractures should be considered during the diagnosis of these conditions. The high prevalence of anemia, rickets, and scurvy in the Poundbury children, and especially the infants, indicates that this community may have adopted child-rearing practices that involved fasting the newborn, a poor quality weaning diet, and swaddling, leading to general malnutrition and inadequate exposure to sunlight. The Pagan group showed no evidence of scurvy or rib fractures, indicating difference in religious and child-rearing practices but that both burial groups were equally susceptible to rickets and anemia suggests a shared poor standard of living in this urban environment.

Excavation of a palatial 2nd century AD house (Terrace House Two) in the ancient city of Ephesus, Turkey in the 1970s produced 10.313 pieces of colored, folded marble which belonged to 54 marble plates of 1.6 cm thickness that originally covered the walls of the banquet hall of the house. The marble plates were completely reassembled and restored by a team of workers over the last 6 years. The plates were recognized as having been sawn from two separate large blocks of "Cipollino verde", a green mylonitized marble from Karystos on the Island of Euboea, Greece. After restoration, it became clear that all slabs had been placed on the wall in approximately the sequence in which they had been cut off by a Roman stone saw. As a result, the marble plates give a full 3D insight in the folded internal structure of 1m3 block of mylonite. The restoration of the slabs was recognized as a first, unique opportunity for detailed reconstruction of the 3D geometry of m-scale folds in mylonitized marble. Photographs were taken of each slab and used to reconstruct their exact arrangement within the originally quarried blocks. Outlines of layers were digitized and a full 3D reconstruction of the internal structure of the block was created using ArcMap and GOCAD. Fold structures in the block include curtain folds and multilayered sheath folds. Several different layers showing these structures were digitized on the photographs of the slab surfaces and virtually mounted back together within the model of the marble block. Due to the serial sectioning into slabs, with cm-scale spacing, the visualization of the 3D geometry of sheath folds was accomplished with a resolution better than 4 cm. Final assembled 3D images reveal how sheath folds emerge from continuous layers and show their overall consistency as well as a constant hinge line orientation of the fold structures. Observations suggest that a single deformation phase was responsible for the evolution of "Cipollino verde" structures

A large plastic deformation of Hadfield steel (frictional action, shear under pressure, filing, and rolling) leads to the growth of an internal effective field at 57Fe nuclei, magnetic-degeneracy removal in the spectra, and delay of the paraprocess up to room temperature. In the Mössbauer spectrum of the 120G13 Hadfield steel, the reversible formation of a hyperfine structure, which is supposedly connected with magnetic ordering, has been detected in situ upon quasi-hydrostatic compression to 26 GPa. The observed growth of magnetic characteristics upon deformation and under high pressure is explained by the deformation-induced redistribution of carbon with the formation of short-range ordering of oxygen and manganese.

The PHOBOS collaboration has carried out a systematic study of charged particle multiplicities in Cu+Cu and Au+Au collisions at the Relativistic Heavy-Ion Collider (RHIC) at Brookhaven National Laboratory. A unique feature of the PHOBOS detector is its ability to measure charged particles over a very wide angular range from 0.5° to 179.5° corresponding to |η| <5.4. The general features of the charged particle multiplicity distributions as a function of pseudo-rapidity, collision energy and centrality, as well as system size, are discussed.

[Medicine as ars in the Roman world. Its advance from sacral to secular approach, its trading and public diffusion: socio-political considerations and their legal consequences].

Coppola, G

1995-01-01

The close linkage between empiric knowledge and its magic religious background in the archaic period appears clearly as a main feature characterizing the medical ars at its beginning, at least till it advances to a full secular approach during the fifth and fourth century B.C. The medical knowledge, which had been a privileged inheritance of the ruling class underwent a rapid transformation with the rise of the Roman Empire and its hegemonic politics that reached its climax during the Punic wars. As it was spread to all social classes it achieved an ever increasing importance leading to its specialisation and trading. This socio-political change had repercussions on the legal field: indeed conventiones concerning medical service came into effect. As far as action was concerned, doctors were permitted to avail themselves of the cognitio extra ordinem in order to get the rewards they were entitled to. The application of the legal tool cognition was however a device embedded in a set of other remedies aiming at granting rewards and incentives i.e. privilegia and salarium. Their development over the period of the Roman Empire was linked with a growing monopoly run by the supreme authority.

This study investigates the application of sulphur isotope ratios (δ 34S) in combination with carbon (δ 13C) and nitrogen (δ 15N) ratios to understand the influence of environmental sulphur on the isotopic composition of archaeological human and faunal remains from Roman era sites in Oxfordshire, UK. Humans ( n = 83), terrestrial animals ( n = 11), and freshwater fish ( n = 5) were analysed for their isotope values from four locations in the Thames River Valley, and a broad range of δ 34S values were found. The δ 34S values from the terrestrial animals were highly variable (-13.6‰ to +0.5‰), but the δ 34S values of the fish were clustered and 34S-depleted (-20.9‰ to -17.3‰). The results of the faunal remains suggest that riverine sulphur influenced the terrestrial sulphur isotopic signatures. Terrestrial animals were possibly raised on the floodplains of the River Thames, where highly 34S-depleted sulphur influenced the soil. The humans show the largest range of δ 34S values (-18.8‰ to +9.6‰) from any archaeological context to date. No differences in δ 34S values were found between the males (-7.8 ± 6.0‰) and females (-5.3 ± 6.8‰), but the females had a linear correlation ( R2 = 0.71; p < 0.0001) between their δ 15N and δ 34S compositions. These δ 34S results suggest a greater dietary variability for the inhabitants of Roman Oxfordshire than previously thought, with some individuals eating solely terrestrial protein resources and others showing a diet almost exclusively based on freshwater protein such as fish. Such large dietary variability was not visible by analysing only the carbon and nitrogen isotope ratios, and this research represents the largest and most detailed application of δ 34S analysis to examine dietary practices (including breastfeeding and weaning patterns) during the Romano-British Period.

Climate, hydrology, land use, and environmental degradation in the lower Rhone Valley during the Roman period

2005-02-01

This paper's aims are three: firstly, to demonstrate the importance of a long-term perspective on socio-environmental dynamics; secondly, to show the relevance of archaeological data in constructing such a long-term history of such dynamics; thirdly, to illustrate with a case study how one may identify the component processes of environmental change from archaeological materials. Taking the Roman occupation of the middle and lower Rhone Valley as a point of departure, the paper identifies some of the processes of regional environmental change. Firstly, it demonstrates the existence of a regional phase of climate degradation during the 2nd century AD. It is in all probability of anthropogenic origin. This degradation seems to have been caused by widespread deforestation in preparation for intensive cultivation of cereals, wine and olives for export to other parts of the Roman Empire. Next, it isolates the principal interactions occurring between relief, soils, and water on the one hand, and the societal dynamics on the other. The location of each settlement is considered representative of an environmental choice, made by its founders at the time the settlement is initiated. These environmental choices, in turn, reflect the perception of the landscape and its resources by the settlers. The principal indicators at our disposal for this study are the relief, soil, and hydrological maps. They are used as a basis for the calculation of the altitude, slope, orientation, annual solar radiation, exposure to the prevailing winds, and fertility of the soil of all sites and their environment. Subsequently, preferences are calculated statistically based on the 1000-odd settlements concerned. The third part of the paper concerns the evolution of the sites. It turns out that the earlier ones are the most successful, in part because they occupied the best locations, but also because they structured the landscape and the territory to their advantage, determined the road network
