Aegeus is the king of Athens and, apparently, an old friend of Medea's. He is childless and eagerly desires the children Medea promises to help him and his wife to have. He serves little purpose in the play other than to provide Medea with a place of refuge in Athens, though his desire for children serves as a powerful contrast to Medea's ultimate choice to kill her own children.
