Jason Cultural

A hero of classical mythology. Jason was the heir to a kingdom in Greece, but his cousin seized the throne. The cousin insisted that the gods would not allow Jason to become king until Jason brought back the miraculous Golden Fleece from a distant country. After many harrowing adventures with his companions, the Argonauts, and with the help of the sorceress Medea, he brought back the fleece. Medea, through her craft, arranged for Jason's cousin to be killed. Jason and Medea then went into exile, raised a family, and lived happily, until Jason announced plans to divorce Medea and marry a princess. Medea, enraged, killed the children she had borne Jason and Jason's bride as well and used her magic to escape. Jason then wandered about, a man out of favor with the gods, and was eventually killed when his old ship, the Argo, fell on him.
