Medea was a powerful sorceress who aided Jason in his quest to retrieve the Golden Fleece. She was the daughter of King Aeetes of Colchis and the granddaughter of the sun god Helios. Medea used her magical powers to help Jason overcome the obstacles set by her father, including the fire-breathing bulls and the ever-growing field of dragon's teeth. Her assistance enabled Jason to succeed in his mission and ultimately win the Golden Fleece.
