This work studies copper alloy artefacts deposited in non-funerary contexts in north-west France between c. 1700-1400 BC. These finds constitute the great majority of the available documentation as there is a shortage of settlements and graves in the area and for the period under study. The book provides a better understanding and a more precise definition of the Atlantic Bronze Age and is based on this particularly abundant documentation, which assembles more than 1200 finds and more than 6600 objects. The author includes a detailed analysis of this extensive documentation (including chance finds). Three main axes of research are tackled : a typological review, dating analysis, and an interpretive approach of the various hoards. Local and wider regionalfactors are considered, as well as the many cultural links with other populations.
