Ancient Greek - tube; plural - askoi, is used to pour small quantities of liquids such as oil. It is recognisable from its flat shape and a spout at one or both ends that could also be used as a handle. They were usually painted decoratively like vases and were mainly used for storing oil and refilling oil lamps. 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. In time the disc version changes the position of spout and handle and becomes the guttus.
