Leda and the Swan (Peter Paul Rubens) either Zeus or Tyndareus, each man is said to be the father of all four children. Castor and Pollux were called the Dioscuri meaning “Zeus’s sons,” even though Castor was mortal because he was the son of Tyndareus and Pollux was immortal because he was the son of Zeus. According to Hermes in Lucians’ "The Dialogues of the Dead", Leda and her daughter (Helen of Troy) are the only women worthy of the title “beauties of old.” Rubens’s depictions of Leda clearly embody the phrase. With Leda’s curvy figure, alabaster skin, and golden hair, she is a sight to behold.
Castor et Pollux In 1737, he was testing the limits of tragedie lyrique; where in 1754, he had done more work with ballet-oriented genres in which he included striking musical compositions that delighted audiences. Thus, Dill proposes that there may have been some commercial concerns behind the change in aesthetic in 1754, as the revised version conformed more to the traditional Lullian aesthetic. He comments that while many see the revision as more innovative, in actuality the 1737 version was the more daring. "Castor et Pollux" appeared in 1737 while the controversy ignited by Rameau's first opera "Hippolyte et Aricie" was still raging.
