The time of callaïs: radiocarbon dates and Bayesian chronological modelling

Research on the provenance of rare green stone materials has produced new insights into the value systems of societies in western and central Europe between the 6th and 3rd millennia cal BC. This contribution presents the results of a Bayesian statistical analysis of 406 current available radiocarbon results from variscite and turquoise (callais) contexts in Europe, along with the results of provenance analyses, undertaken to investigate the fine-grained temporal pattern for the exploitation, circulation and deposition of callais artifacts.
