Using ceramic evidence, this paper examines the differences between the supply of coastal and inland regions of Africa from the 4th to 7th c. A.D. While a narrow band of coastline across the Mediterranean seems to be fully integrated into a common system of consumption (e.g. importing overseas amphora and the principal African Red Slip (ARS) forms), most of the inland regions seem to be more impervious to non-regional products (e.g. no transport amphorae and mainly local ARS); this is a situation which is particularly obvious in the Algerian high plains. Nevertheless, an accurate analysis of the documentation allows us to discern some indications of inter-provincial contacts via ancient east-west terrestrial routes.
