1213 BC - Theseus, legendary King of Athens, is deposed and succeeded by Menestheus, great-grandson of Erechtheus and second cousin of Theseus' father Aegeus. Menestheus is reportedly assisted by Castor and Polydeuces of Sparta, who want to reclaim their sister Helen from her first husband Theseus. The latter seeks refuge in Skyros, whose King Lycomedes is an old friend and ally. Lycomedes, however, considers his visitor a threat to the throne and proceeds to assassinate him (though other accounts place these events a decade later, in the 1200s BC).
