Leda and the Swan is a story and subject in art from Greek mythology. In many versions of the story, Zeus took the form of a swan and raped or seduced Leda on the same night that she slept with her husband Tyndareus, the King of Sparta. From this night, Leda bore to Zeus Helen and Pollux, while at the same time bearing Castor and Clytemnestra to her husband Tyndareus.
In other versions of the myth, it is Nemesis, the goddess who personified the disaster that awaited those suffering from the pride of Hubris, who is seduced by Zeus. Nemesis, in the form of a goose, lays an egg which is found and passed to Leda who keeps it until it hatches. It is in this way that she becomes the mother of Helen.
