Trade and colonization caused an unprecedented increase in Mediterranean human mobility in the first millennium BCE. Often seen as a dividing force, warfare is in fact another catalyst of culture contact. We provide insight into the demographic dynamics of ancient warfare by reporting genome-wide data from fifth-century soldiers who fought for the army of the Greek Sicilian colony of Himera, along with representatives of the civilian population, nearby indigenous settlements, and 96 present-day individuals from Italy and Greece. Unlike the rest of the sample, many soldiers had ancestral origins in northern Europe, the Steppe, and the Caucasus. Integrating genetic, archaeological, isotopic, and historical data, these results illustrate the significant role mercenaries played in ancient Greek armies and highlight how participation in war contributed to continental-scale human mobility in the Classical world.

Our findings generally support the hypothesis that skeletal stress is evidence of frailty (i.e., leading to greater risk of mortality). However, the relationship between stress and frailty is complicated by social factors, when considering historical context. In particular, a possible "soldier-class" may have experienced less stress than the overall civilian population.

In this paper we present a geophysical survey that was carried out as a research activity during field trips to the Himera archaeological site, where relics of a large Greek settlement are still buried, effected by a joint group of archaeologists and geophysicists during an educational project. Twodimensional (2D) resistivity and ground-penetrating radar (GPR) surveys were performed to locate buried archaeological structures at this archaeological site. The results of the GPR surveys show some anomalies characterized by semi-hyperbolic shapes. In some restricted areas of the town, two grids of parallel GPR profiles were acquired while time-and depth-slices were calculated to identify the extension of the buried structures. In fact, the shapes of many anomalies recognized in the slices seem to describe the distribution of the relics (i.e. walls, roads, etc.).A 2D electrical resistivity profile showed clear anomalies, which were connected with wall-like relics. This was also obtained by using on-site calibration on partially uncovered structures, while the low background resistivity values were interpreted as representing river deposits having different moisture characteristics. Recommendations were also given to the archaeological site-excavators, following which some of the results were confirmed by subsequent archaeological excavations.

The present work is part of a project aimed at studying the pigments and painting techniques used by Albanian iconographers to produce Byzantine and post- Byzantine icons dating from the fourteenth to the nineteenth centuries; the state of conservation of these icons was also explored. Inorganic pigments are identified by means of X-ray fluorescence, reflectance spectrophotometry and UV fluorescence analysis. These analysis techniques were performed to discriminate between pigments on the basis of their typical features. Moreover, the study of the optical properties of paintings is of fundamental importance for correct restoration. This work enabled us to recognise the palette used in two artworks by anonymous painters of the fourteenth and fifteenth centuries. Only three small samples were taken from the edge and the back of the wooden tables in order to achieve information on preparatory layers. Twelve to fourteen non-destructive measurements were made to characterise the palette used by the two anonymous painters
