Leda and the Swan is a story and subject in art from Greek mythology in which the god Zeus, in the form of a swan, seduces or rapes Leda, a Spartan queen. According to later Greek mythology, Leda bore Helen and Polydeuces, children of Zeus, while at the same time bearing Castor and Clytemnestra, children of her husband Tyndareus, the King of Sparta. According to many versions of the story, Zeus took the form of a swan and raped Leda on the same night she slept with her husband King Tyndareus. In some versions, she laid two eggs from which the children hatched.[2] In other versions, Helen is a daughter of Nemesis, the goddess who personified the disaster that awaited those suffering from the pride of Hubris.
Especially in art, the degree of consent by Leda to the relationship seems to vary considerably; there are numerous depictions, for example by Leonardo da Vinci, that show Leda affectionately embracing the swan, as their children play.
The subject was rarely seen in the large-scale sculpture of antiquity, although a representation of Leda in sculpture has been attributed in modern times to Timotheus (compare illustration, below left); small-scale sculptures survive showing both reclining and standing poses,[3] in cameos and engraved gems, rings, and terracotta oil lamps. Thanks to the literary renditions of Ovid and Fulgentius[4] it was a well-known myth through the Middle Ages, but emerged more prominently as a classicizing theme, with erotic overtones, in the Italian Renaissance.
