A study was undertaken of musculoskeletal stress markers in the human remains of several ancient populations of the Iberian Peninsula. Frequencies by age group, sex, and side were recorded and compared among the different populations. Results of the study coincide with the available historical and archeological data. The differences observed among these populations are probably due to ecological and socio-cultural factors.

C4 plants (e.g. maize, millet), part of our current diet, are only endemic of reduced areas in South-Europe due to their need of warm climates. Since the first vestiges of agriculture in Europe remains of C4 plants were recorded but their overall proportion in the human diet remains unknown. Therefore, isotopic (δ13C and δ15N) composition of bone collagen from the skeletal remains (human and animals) of a Celtic population, Cenomani Gauls, from Verona (3rd to 1st century BC) in the NE Italy provide a new perspective on this matter. The δ13C collagen values of 90 human skeletal individuals range between −20.2‰ and −9.7‰ (V-PDB) with a mean value of −15.3‰. As present day C4 plants have δ13C values around −11‰, which is equivalent to −9.5‰ for samples of preindustrial age, the less negative δ13C values in these individuals indicate a diet dominated by C4 plants. This palaeodietary study indicates that some European populations predominantly consumed cultivated C4 plants 2100 year B.P. This is supported by the paleobotanical records and ancient Roman sources (e.g. Pliny the Elder), which indicate that millet was a staple food in South-Europe.

The main aim of this study was to analyze the presence and distribution of cranial trauma, as possible evidence of violence, in remains from the Neolithic to Bronze Age from the SE Iberian Peninsula. The sample contains skulls, crania, and cranial vaults belonging to 410 prehistoric individuals. We also studied 267 crania from medieval and modern times for comparative purposes. All lesions in the prehistoric crania are healed and none of them can be attributed to a specific weapon. In all studied populations, injuries were more frequent in adults than in subadults and also in males than in females, denoting a sexual division in the risk of suffering accidents or intentional violence. According to the archeological record, the development of societies in the SE Iberian Peninsula during these periods must have entailed an increase in conflict. However, a high frequency of cranial traumatic injuries was observed in the Neolithic series, theoretically a less conflictive time, and the lowest frequency was in crania from the 3rd millennium B.C. (Copper Age), which is characterized by the archeologists as a period of increasing violence. The relatively large size and the high rate of injuries in Neolithic crania and the practice of cannibalism are strongly suggestive of episodes of interpersonal or intergroup conflict. The number and distribution of injuries in Bronze Age is consistent with the increase in violence at that time described by most archeologists.

Objectives: The presence of a gendered subdivision of labor has been bioarchaeologically investigated in various prehistoric and historical contexts. Little is known, however, about the type of differences in daily activities characterizing men and women among the Celtic communities of Italy. The focus of the present study is the analysis of differences in patterns of entheseal changes (ECs) and long bone shape and robusticity between sexes among the Cenomani Gauls of Seminario Vescovile (SV-Verona, Italy, third-first century BC). Materials and Methods: The sample includes 56 adult individuals (22 females and 34 males). Presence of ECs on nine bilateral postcranial attachment sites, and values of humeral and femoral shape and robusticity indices based on external measurements were compared between sexes by means of generalized linear models and Mann-Whitney tests. Results: Results show a lack of difference between sexes in long bone shape and robusticity, and a higher incidence of upper and, especially, lower limb ECs in males. Discussion: These results suggest the presence of sex-specific activities at SV mostly related to farming and differently influencing the considered variables. Also, this study suggests the relevance of a series of nonbiomechanical factors (developmental, hormonal, genetic, and methodological) when attempting biocultural reconstructions from osteoarchaeological samples.

Study of the human remains of King Pedro I of Castile (1334-1369), his wife Queen Maria of Padilla (c. 1334-1361), and three other members of his family offered the possibility to investigate the diet of an elite in the medieval Iberian Peninsula by analyzing δ 15 N and δ 13 C values in collagen samples of their bones. Two medieval archaeological samples were selected for comparative purposes: a Christian sample (n=5) from Palacios de la Sierra (Burgos), and a Muslim sample (n=5) from La Torrecilla (Granada). Results obtained were compared with published data on other medieval populations of the Iberian Peninsula with the aim of improving knowledge on the diet of medieval populations, especially elite groups. Differences in the consumption of C3 and C4 plants were observed between Christians and Muslims, as previously reported. δ 15 N values indicated social class differences. The diet of the royal family was characterized by mainly C3 plants and an extremely high animal protein intake characteristic of carnivores. These results are consistent with historical data on the life circumstances of this family.
