Argo. A fifty-oared ship in which Jason and his companions made their voyage to Colchis in search of the golden fleece. This ship was built of pines cut from Mount Pelion, which, although larger than any other previously constructed, moved lightly and easily, and was therefore called the Argo (swift-sailing). From her name, those who embarked in her were called Argonauts. The mast of the Argo was taken from the forest of Dodona, where the oaks were endowed with the power of making predictions; therefore, the ship was regarded as an animated being, in accord with Fate, to which a man might commit himself with confidence.
