''Leda and the Swan'', 16th-century copy after the lost painting by
Michelangelo
In
Greek mythology, 'Leda' ('Λήδα') was daughter of the
Aetolian king
Thestius, and wife of the king
Tyndareus, of
Sparta. Her myth gave rise to the popular motif in Renaissance and later art of
Leda and the Swan. She was the mother of
Helen of Troy,
Clytemnestra, and
Castor and Pollux.
Leda was loved by
Zeus, who seduced her in the guise of a
swan. As a swan, Zeus fell into her arms for protection from a pursuing eagle. Their consummation, on the same night as Leda lay with her husband Tyndareus, resulted in two eggs from which hatched
Helen—later known as the beautiful ''Helen Of Troy'',
Clytemnestra, and
Castor and Pollux (also known as the
Dioscuri—also spelled Kastor and Polydeuces). Which children are the progeny of Tyndareus, the mortal king, and which are of Zeus, and are thus half-immortal, is not consistent among accounts, nor is which child hatched from which egg. The split is almost always half mortal, half divine, although the pairings do not always reflect the children's heritage pairings. Castor and Polydeuces are sometimes both mortal, sometimes both divine. One consistent point is that if only one of them is immortal, it is Polydeuces.
In Homer's Iliad, Helen looks down from the walls of Troy and wonders why she does not see her brothers among the Achaeans. The narrator remarks that they are both already dead and buried back in their homeland of Lacedaemon, thus suggesting that at least in some early traditions, both were mortal. The consensus is that Helen and Polydeuces were the immortal children of Zeus, while Castor and Clytemnestra were the mortal children of Tyndareus.
Leda also had other daughters by Tyndareus:
Timandra,
Phoebe,
Philonoe.
Another account of the myth states that
Nemesis was the mother of Helen, and was also impregnated by Zeus in the guise of a swan. A shepherd found the egg and gave it to Leda, who carefully kept it in a chest until the egg hatched. When the egg hatched, Leda adopted Helen as her daughter. Zeus also commemorated the birth of Helen by creating the constellation
Cygnus, the Swan, in the sky.
Leda and the swan and Leda and the egg were popular subjects in the ancient art. In the
postclassical arts, it became a potent source of inspiration.
