Amphorae were containers used to transport and trade liquid, wine and oil, or solid food, such as wheat, capers, olives, meat, salted fish and fish sauce (or garum).
The amphorae were placed in the hold of the ship according to a precise order that, during the excavation of a wreck, can be recognised by their arrangement, lying on the seabed in several layers. Identifying the production plant of an amphora makes it possible to define the trade relations between the various production centres by reconstructing the trade route followed by the ship before it was wrecked.
