was the ship on which Jason
and the Argonauts
sailed from Iolcus
to retrieve the Golden Fleece
The Argo was built by Argus, son of Phrixus. The Argo had the gifts of speech and prophecy because it was made of oak wood from the oracle at Dodona.
The constellation Argo Navis represented the Argo; it has since been broken up among the ship's sails, keel and stern.
