The MOBILITH project is based on the study of lithic industries from the first agro-pastoral communities in continental Europe (5250 to 4750 BCE). In this spatio-temporal framework, the LBK was fragmented into a mosaic of cultural entities. Four key areas located in Belgium, the Netherlands, Germany and the Czech Republic have been selected because they reflect distinct cultural trajectories. The analysis will focus on the reconstruction of learning networks and the circulation of raw materials networks. By modelling the evolution of these networks based on a demographic approach and a Social Network Analysis, the aim will be to understand the nature and impact of mobility on the cultural trajectories perceived by archaeologists. This 42-month project is structured around a combination of original study methods, the scope of which is fully in line with the objectives of the ANR's Axis D.06 (Studies of the past, heritage, cultures). In particular, the diachronic perspective adopted will shed new light on cultural evolution through the prism of an archaeology of the transmission of technical know-how.
