Tyndareus was king of Sparta and held huge tracts of the ripest southern lands, the kind my father coveted. I had heard of his daughter too, rumored to be the fairest woman in our countries.

Nine months later, her womb yielded two sets of twins: Clytemnestra and Castor, children of her mortal husband; Helen and Polydeuces, the shining cygnets of the god.
