Abstract
The genetic history and the degree of mobility characterizing the “Celtic” population during the Late Iron Age (4th -1st century BCE) have become central topics in archaeology and anthropology. However, despite the steady increase of archaeological, biomolecular and biogeochemical studies on central European and British contexts, few data are available for the Northern Italian and Swiss territories. During the Late Iron Age the geographic areas corresponding to modern Switzerland and Northern Italy played a crucial role in connecting Central and Southern Europe. This connection involved not only forms of cultural transmission (e.g. diffusion of the La Tène material culture), but also the actual movement of people through the Alpine range. During the Late Iron Age the European area was affected by migrations of different human groups, with southward migratory processes documented historically and by archaeological traces in both Northern and Central Italy. Little is known however about the similarities and differences in genetic variability, mobility patterns, and social organization between the Late Iron Age populations distributed on the two sides of the Alpine range. The present project aims to address this issue, by means of a multidisciplinary (genetic, and isotopic) analysis of a large skeletal sample representing Late Iron Age populations of modern Switzerland and Northern Italy (Cenomani of Verona) between the 4th -1st centuries BCE. In particular, the present project aims to: 1) reconstruct the genetic history and variation of the “Celtic” groups inhabiting the Swiss and Northern Italian areas by analysing the genetic relationship among groups and the genetic structure of groups; 2) estimate the degree of mobility characterizing these populations, and the differences and similarities in mobility (e.g. frequencies of nonlocals, sex and age patterns, long-versus short distance mobility) between them; 3) test for the presence of relationships between mobility, kinship patterns, and social organization in each area, and the possible similarities and differences in social organization between the Swiss and Northern Italian communities. Analytical methods will include the study of ancient DNA (aDNA) and of stable isotopes (δ15N, δ13C, δ34S, δ18O, δ2H), in conjunction with a quantitative analysis of the archaeological evidence.
This project will be the first to apply a multidisciplinary approach to the study of Late Iron Age populations from Continental Europe, and will generate new openly-accessible isotopic and genomic data for future studies on these populations from both sides of the Alps. The results will be disseminated across different target groups by means of: i) scientific papers, international conferences participation and open access data repository for scientists. ii) social networks and media platforms, didactic activities in schools, public conferences and interview/articles in local newspapers for the non-scientist audience.
