Events and trends

• Aegeus, legendary King of Athens, receives a false message that his designated heir Theseus, his son by Aethra of Troezena, is dead. Theseus had been sent to his overlord Minos of Crete as an offering to the Minotaur. Medus, Aegeus' only other son (by Medea of Colchis), had been exiled in Asia and would become legendary ancestor to the Medes. Believing himself without heirs the King commits suicide after a reign of 48 years. He is succeeded by Theseus, who actually still lives. The Aegean Sea is reportedly named in his honor.
