When Pelias 1 died his son Acastus succeeded him as king of Iolcus and he expelled both Jason and Medea from the city. Some say that Medea was able to restore youth and that she gave Aeson, Jason 's father, his youth back. But what he did with his new youth is unknown. Medea and the daughters of Pelias 1 Jason changes his mind. Jason and Medea came then to Corinth , and lived there happily for ten years, until Jason felt ready for a younger and more representative wife, instead of a foreigner and sorceress.
New marriage leads to tragedy.
Jason married the daughter of the king of Corinth and divorced Medea. But this humilitation and betrayal was more than Medea could bear and, in revenge, she caused the death of both King Creon 3 of Corinth and his daughter, Jason 's new wife or, as some say bethrothed, Glauce 4. Creon 3 died when he tried to rescue his daughter. But some say that the king fell upon her daughter's corpse and could not separate from her, as his flesh was torn from his bones when he tried to rise. Still others say that Glauce 4 died when she threw herself into a well in the belief that its water would be a remedy against Medea's poison.
