In Greek mythology, the Argo (//; in Greek: Ἀργώ, meaning 'swift') was the ship on which Jason and the Argonauts sailed from Iolcos to Colchis to retrieve the Golden Fleece. She was named after her builder, Argus.
The Argo was constructed by the shipwright Argus, and its crew were specially protected by the goddess Hera. The best source for the myth is the Argonautica by Apollonius Rhodius. According to a variety of sources of the legend, the Argo was said to have been planned or constructed with the help of Athena. According to certain sources, the Argo was the first ship to sail the seas. It was Athena who taught Tiphys to attach the sails to the mast, as he was the steersman and would need an absolute knowledge of the workings of the ship. According to other legends, she contained in her prow a magical piece of timber from the sacred forest of Dodona, which could speak and render prophecies.
Several authors of antiquity (Apollonius Rhodius, Pliny, Philostephanus) discussed the hypothetical shape of the ship. Generally she was imagined like a Greek warship, a galley, and authors hypothesized that she was the first ship of this type that had gone out on a high-sea voyage.
