An assymetric vessel, often squat and duck-shaped, with an off-center mouth, convex top, and single arching handle. It was originally shaped like a leather bottle (uter) for holding water, oil, or wine. Some example have two mouths, one for filling and one for emptying, and others are quite unbalanced and have strange mouths. It later assumed the form of an earthenware pitcher. Askos were popular in the Aegean from the Early Helladic to the Classical period.
