Archaeometric characterization of prehistoric pottery from Baħrija, Malta

The end of prehistory in the Maltese archipelago is characterized by the production of a problematic class of pottery, until now attested just at the site of Baħrija, on the western coast of Malta. Such a production represents a break with the tradition in terms of repertoire of shapes, style and technology and it has been interpreted as the result of contact between locals and foreign immigrants. The recent overall reappraisal of the unpublished ceramic assemblage collected during the excavations carried out at Baħrija, represents a unique opportunity to focus on the technological aspects of the production, trying to shed light on the issue of the break with the tradition and the impact of external influxes. Petrographic analysis on thin sections and chemical analyses via X-ray fluorescence spectroscopy (XRF) and laser ablation-inductively coupled plasma mass spectroscopy (LA-ICP-MS) have been carried out to characterize the Baħrija pottery production in order to interpret from a different angle the issue of the possible arrival of newcomers and establishment of a foreign enclave in Malta, which until now has been hypothesized only on the basis of the sudden emergence of the Baħrija pottery.
