The story · Beginning

Jason was the rightful heir to the throne of Iolcus, displaced as a child by his uncle Pelias. Hidden away with the centaur Chiron and raised on Mount Pelion, he returned to claim his kingdom as a young man. Pelias agreed to step down — on the condition that Jason first retrieve the Golden Fleece, the hide of the ram Chrysomallus, kept in the kingdom of Colchis on the far side of the Black Sea, guarded by a sleepless dragon.

The story · Middle

Jason commissioned the ship Argo and gathered a crew of fifty heroes — the Argonauts — including Heracles, the Dioscuri (Castor and Pollux), Orpheus, and Atalanta. They survived the Symplegades (the clashing rocks at the Bosphorus), a battle with the Harpies, the Sirens, and the bronze giant Talos. At Colchis, King Aeëtes set Jason impossible tasks; the king's daughter Medea, falling in love with him, used her magic to help him pass each one and finally to put the dragon to sleep.

"Medea cast the dragon into a sleep with her drugs, and Jason carried the Golden Fleece down to the Argo."

The story · Resolution

Jason took the fleece and Medea fled with him. The voyage home was almost as hard as the journey out. He returned to Iolcus to find his father dead; his revenge on Pelias, carried out by Medea, drove him into exile. Years later, having abandoned Medea for the daughter of the king of Corinth, he was killed in his sleep by a beam falling from the rotting hull of the Argo itself — pulled up onto a Corinthian beach as a relic. The ship was placed among the stars by Athena as Argo Navis (now broken into Carina, Vela, and Puppis).
