Wikipedia: Askos (Ancient Greek ἀσκός "tube"; plural: ἀσκοί - askoi) is the name given in modern terminology to a type of ancient Greek pottery vessel 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.
