The project aims at improving the knowledge of the Roman economy and trade in the Western Mediterranean Sea (the 4th century BC – the 1st century AD), thanks to the use of modern research methodologies. The project is focused on the study of pottery production centers and related ceramics. New investigations have been carried out, whilst some are still on-going. Pottery is very common in archaeological records and is one of the most important markers used by archaeologists to date contexts, reconstruct trade routes and economic patterns of urban sites and sharpen our understanding of the technical level of ancient societies. The core of the methodology applied in the project is the integration of archaeology and archaeometry (in particular, paste computational analyses to detect the provenance of raw materials). For ceramics, especially, the existing data on Central and Southern Italy production centers, distribution and trade networks are being gathered to offer a new understanding and interpretation of them.
