Trade Networks in the Neighbouring Roman Provinces of Aquitania-Tarraconensis on the Bay of Biscay: Evidence from Petrographic and Chemical Analyses of Common Coarse Ware Pottery

Common non-wheel-thrown Roman pottery from the southern Aquitania and north-eastern of Tarraconensis provinces (CNT-AQTA) Early Later Empire (1st to 5th centuries AD) has been studied. Petrological, mineralogical, chemical analyses were conducted contrast with archaeological study pottery. The composition many samples displays different patterns burial modification, limiting their use for provenance diffusion studies. Particular emphasis paid petrographic features fabrics, as they do not change during burial, reflecting nature raw material making it possible identify areas materials. Around Bay Biscay, same tradition continued in neighbouring times. Petrographic studies make determine distribution changes trade networks period across area Biscay being
