Océan, céramiques et îles dans l’ouest de la France. Approche archéométrique des relations paléo-économiques des populations insulaires du Néolithique à l’Antiquité

Abstract : Sea, ceramics and islands in western France: archaeometric approach to paleo-economic relations of island populations from the Neolithic to Antiquity. This book is about research on the development of ceramic production and exchange between the mainland and islands of Brittany from the Neolithic to the Gallo-Roman period. Archaeometric analysis of ceramics is used to explore the development of communication networks: the movement of people and of products between the islands and the mainland. Did these islands produce their own pottery or were they dependent on mainland production? By determining whether pottery was locally produced or imported, it is possible to identify the changing degrees of connection with, or isolation from, wider networks. Several analytical methods have been employed to examine 368 sherds of pottery from 25 sites. Macroscopic observations were made in order to document surface treatments, as well as microscopic examination of ceramic thin sections for the identification of the mineralogical composition of the clay, and to determine its geological and geographic origins. These techniques have been complemented with chemical analyses: SEM-EDS, XR-D and P-XRF. Finally, a new methodological approach has been used to provenance the clays: LA-ICP-MS analysis. This method is based on chemical comparisons of the mineral inclusions in the ceramic pastes with the same mineral types in the parent rocks. It can determine more precisely the origins of clays, especially when the pastes do not offer characteristic elements that allow them to be distinguished from other productions. The long chronological scope of this study allows us to document the evolution of ceramic characteristics and the changing locations of clay supply and pottery production. The results of this research provide new evidence about the prehistoric occupation of the islands of Brittany.
