Aux origines de l'alimentation méditerranéenne : Analyses isotopiques de vestiges bioarchéologiques de l'Antiquité au début du Moyen Âge dans le Sud-Est de la France

Abstract : At the transition between Antiquity and the Middle Ages, the reconstruction of diet at an individual level allows to define the impact on daily life of the changes in institutions, economic systems and culture. It makes also possible to address the question of "Mediterranean diet(s)". Finally, this scale of interpretation offers the possibility to compare diet with the characteristic of each individual (age, sex, funeral practices) and site (status, environment) in order to evaluate the extant of influence of those criteria. This research involves the analysis of the isotopic ratios of nitrogen and carbon (d13C and d15N) in bone collagen from 371 humans and 388 animals. The samples come from 23 sites in Languedoc and Provence, dated from the end of the 4th century to the beginning of the 12th century. A corpus of comparison, based on isotopic data from the bibliography, includes 1431 humans from Spain, Croatia, Italy and Greece. Between the 4th and 8th centuries in Provence, the consumption of marine resources is perceptible in Marseille and Aix-en-Provence, revealing the presence of a supply network up to 50 km from the coast that serves urban centres throughout the period. Between the 9th and 12th centuries, an increase in the consumption of aquatic resources is visible at the turn of the millennium, probably reflecting the Church's control over dietary habits, even in the countryside. Finally, it was possible to note a homogeneity in South-East France compared to other Mediterranean regions. This result indicates a lower importance of marine resources and millet (C4 resources) for this region and so, an influence of cultural affiliation on consumption choices in these two periods.
