The author describes them as "having honour equal to gods", living on alternate days because of the intervention of Zeus. In both the "Odyssey" and in Hesiod, they are described as the sons of Tyndareus and Leda. In Pindar, Pollux is the son of Zeus while Castor is the son of the mortal Tyndareus. The theme of ambiguous parentage is not unique to Castor and Pollux; similar characterisations appear in
Leda and the Swan Pollux, in some versions of the myth). Clytaemnestra, who killed her husband, Agamemnon, leader of the Greeks at Troy, was also supposed to have hatched from one of Leda's eggs. The poem is regularly praised as one of Yeats's masterpieces. Camille Paglia, said the poem "could justifiably be considered the best of the twentieth century," and that "all human beings, like Leda, are caught up moment by moment in the 'white rush' of experience. For Yeats, the only salvation is the shapeliness and stillness of art." See external links for a bas relief arranged in the position as described by
