Leda was the daughter of King Thestius of Aetolia. She was married to King Tyndareus of Sparta and became queen there. She was seduced by Zeus in the shape of a swan, and bore two children; Helen and Polydeuces. She also bore her husband two children; Clytaemnestra and Castor, on the same day. She is also sometimes considered to have more daughters.

Family

Leda was the daughter of the Aetolian King Thestius hence she was also called Thestias. Her mother was either Leucippe, Deidameia, daughter of Perieres, Eurythemis, daughter of Cleoboea, or Laophonte, daughter of Pleuron. According to Alcman, Leda's parents were Glaucus and Laophonte while Eumelus attested that they are Sisyphus and Panteiduia or Paneidyia.

She married king Tyndareus of Sparta and by him became the mother of Helen of Troy, Clytemnestra, and Castor and Pollux (also spelled "Castor and Polydeuces"). Leda also had three other daughters by Tyndareus: Timandra, Phoebe, and Philonoe.

Mythology

Leda was admired by Zeus, who raped 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). Which children are the progeny of Tyndareus the mortal king, and which are of Zeus and 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 Pollux are sometimes both mortal, sometimes both divine. One consistent point is that if only one of them is immortal, it is Pollux. It is also always stated that Helen is the daughter of Zeus.

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 the Homeric tradition, both were mortal.

Another account of the myth states that Nemesis (Νέμεσις) 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 (Κύκνος), the Swan, in the sky.
