Functional analysis of stone grinding and polishing tools from the earliest Neolithic of north-western Europe
Résumé
This reconstruction of grinding, pounding, hammering and abrading activities in the Early Neolithic of north-western Europe (Linearbandkeramik and Villeneuve-Saint-Germain cultures, 5100e4700 BC) is based on the study of 1289 sandstone tools from 17 sites located in the main Paris basin river valleys (Aisne, Eure, Marne, Oise, Seine, Yonne). An original method of functional identification was elaborated, relying on observation of use-wear with a stereoscopic microscope (under120). Identification of traces of use relied on an experimental referential of 92 samples. These include (1) grinding cereals, (2) pounding temper, colourants and various plants, (3) shaping mineral, vegetal and animal objects by polishing (schist, limestones, bone, antler, wood), (4) softening skin. A significant observation concerns the use of small handstones for grain dehusking and larger handstones for grain grinding. Recycling is a widespread feature, with multipurpose handstones and frequent reuse of lower grinding tools for obtaining colourants. A change in the function of tools can also be observed between the Linearbandkeramik and the Villeneuve-Saint-Germain.
