A small vessel for pouring oil with a convex body and a basket handle which reaches to the oblique spout. Shape: The shape is an ideal one for pouring oil, for the angle of the body and spout causes the liquid to come out in a thin stream when lightly tilted. History: The askos is a new shape in Attic red-figure and black-painted wares. It appears from about 480 down to the fourth century B.C. Term: Its shape resembles that of a wineskin with its opening closed, whence the name, for the Greek word for wineskin was askos. There is no evidence that the word askos was used by the Greeks to describe this vessel.
