The Athenian askos (pl. askoi) is a small, round vessel with a flat bottom and an over-arching handle that joins the obliquely-angled neck. There is little room for extensive decoration, and often a pair of figures suffices.
The Greek word askos refers to the bags made of animal-skin that were used to carry wine; in Athenian red-figure scenes, they are often depicted in the arms of satyrs. Its modern application to this pottery-shape originates in the supposed similarity of some examples to animal-skins.
