Research Theme 5: Portus' primary role was to supply the 800,000 inhabitants of Rome with foodstuffs and the other materials. It was also a hub for re-distributing imports from other Mediterranean ports and, to a lesser extent, exporting construction material and other products from the Tiber valley. Analyses of amphorae, table and cooking wares, bricks, decorative stone and carbonized seeds from our excavations has enabled us to trace changing commercial connections to known sources across the whole Mediterranean basin, underlining the particular importance of north Africa (ceramics) and the east Mediterranean (decorative stone). Our work has also reveal the presence of Italian products ceramics, either for use in the port or for export.
