The Dioscuri: Castor and Pollux
Castor and Pollux, the famed Dioscuri, are notable in Greek and Roman mythology for their mixed parentage. Castor was the mortal son of Tyndareus, the Spartan king, while Pollux was the divine offspring of Zeus, who seduced their mother, Leda, in the guise of a swan. This dual parentage exemplifies the concept of heteropaternal superfecundation, a unique mythological phenomenon.

Birth and Mythical Accounts
Their birth is often described through contrasting narratives. Some myths suggest they, along with their sisters Helen of Troy and Clytemnestra, hatched from an egg laid by Leda. While the Homeric “Odyssey” and Hesiod’s “Catalogue” describe both as sons of Tyndareus, Pindar introduces the divine lineage of Pollux, attributing his immortality to Zeus’s intervention.
