Amphorae were large ceramic jars employed in the Roman world for the packaging and transport of a limited set of liquid and semi-liquid foodstuffs—chiefly wine, olive oil, and various kinds of fish preserves and processed fish products—and certain other substances. They were manufactured in a large number of distinct shapes—generally referred to as classes—linked to specific regions and employed for specific kinds of contents. For this reason amphorae are treated by scholars as proxy markers for the distribution of these categories of foodstuffs and, on account of their abundance and ubiquity in the archaeological record, they constitute one of the most important forms of material evidence for economic activity in the Roman world from the 3rd century bce down to the end of antiquity.We possess a wide range of evidence relating to amphorae. The remains of workshops in which amphorae were manufactured have been identified in many parts of the Roman world, and many of these have been subject to surface investigations and/or excavation. Amphorae occur in abundance on archaeological sites in most parts of the Roman world, most often in fragmentary condition, though in some cases more or less intact. These include amphora production workshops, sites relating to their filling or distribution (food processing/packaging facilities, .
