King Aeson of Corinth was a famed Grecian ruler and father of King Jason. He was poisoned by Ares and lay unconscious for two weeks. This prompted Jason, Hercules and Iolaus to go on a quest for the Golden Fleece to cure him. They did find the Fleece and manage to save Aeson only to have Ares break the king's neck. This left Jason as king of Corinth (Young Hercules). Jason later met with his father in the Underworld, who was momentarily distraught when he believed his son had died and was not simply visiting with Hercules. (YH: "A Lady in Hades")
