Terracotta zoomorphic askos (vessel), Metropolitan Museum of Art

Askos can be recognized by their flat shape and a spout at one or both ends, which could also be used as a handle. They were usually ornately painted, like vases, and were used mainly for storing oil and refilling oil lamps. They were widely traded in and around the Mediterranean. The original meaning of the word ἀσκός was bard. From them the early Christian sect of Ascotarians takes its name. The Ascodrugites, however, are not related to them except by popular etymology.
