Workshop Places at Chessy (Seine-et-Marne Dpt., France): Contextual and Technological Aspects

Abstract

In the second half of the fifth millennium BC, a new model of supply and processing of siliceous rocks appeared in western Lesser Poland (Małopolska). The existing methods of production of blades and flakes from small cores obtained at a short distance from the settlement were supplemented by those enabling the production of much longer blades from cores made from raw material obtained by mining. The significant increase in the size of lithics meant that this moment was referred to as “the metric change” (Polish: przełom metryczny). It was assumed that this was due to internal technological development within the early Neolithic communities of the Lengyel-Polgár cycle. This paper introduces a different explanation for this phenomenon. It is argued that the new model of supply appeared as an already developed model that was implemented by experienced outsiders. A thesis that the indicated technological caesura is not categorical and new patterns in a relatively small area could co-exist with previous ones.
