Tarraco was the ancient capital of Hispania Tarraconensis, a Roman province in the Western Mediterranean. It was a strategic enclave and one of the most important ports during the Roman Empire and Late Antiquity. The archaeological record of the city shows a variety of imported products arrived from several regions including a significant amount of eastern Mediterranean wares, amongst which there are fine, table-wares, amphorae, and coarse and cooking wares. This work focuses on the integrated archaeological and archaeometric study of these eastern types of Late Roman cooking wares from the mid-7th century to the early 8th century. In previous works, these products were classified as Aegean and North Palestinian imports. However, for some of these materials a detailed macroscopic study revealed similarities with local/regional products, opening the possibility of regional ware imitating eastern prototypes. An analytical study was carried out, applying a combination of WD-XRF and Optical Microscopy to identify their provenance. The results point to the coexistence of imported eastern Mediterranean wares and local/regional imitations. At the same time, some of the typologies identified as eastern Mediterranean products seem to have been produced locally or regionally.
