Bayesian radiocarbon modeling and the absolute chronology of the Middle Bronze Age Thapsos facies in mainland Sicily : a view from St. Ippolito (Caltagirone)

Abstract

One of the most debated and explored period of the prehistory of Sicily is the Middle Bronze Age (15th-13th century BCE), which is considered as a crucial moment for the development of local prehistoric social, economic, and cross-cultural dynamics. The local Thapsos culture is what best represents this chronological period and is characterized at some sites by theoccurrence of datable ceramic imports from the Aegean alongside their local replicas. These have helped researchers with estab-lishing a local relative chronology based indirect beacons with eastern Mediterranean contexts. However, when it comes to an independent absolute chronology for MBA context in mainland Sicily, no recent program of radiocarbon dating has been carried out so far. In this contribution, the authors devise a Bayesian model based on evidence from a stratified MBA context at St. Ippolito (Caltagirone, central-eastern Sicily) where a set of seven samples have been radiocarbon dated. The study aims to assess which part of the overall development of the MBA the analyzed context corresponds to, to absolute date the activities represented by the deposit’s layers, and to lay the basis to tentatively bracket in time the use of some associated ceramic materials.peer-reviewe
