Previously unpublished Roman pottery from the Thames Estuary was studied by the author in 1985 and 1986 for the voluntary body Marine Archaeological Surveys (MAS) and is presented as a contribution to wider initiatives on the Roman archaeology of this important social and economic artery between South-East England and the wider world. The purpose of this paper is to complement the ongoing review by Michael Walsh of Roman wrecks in UK waters (a research partnership between Southampton University and the British Museum) and that of the ‘Pudding Pan’ assemblage, much of which is in private collections.
