Nemesis mother goddess, Cybele. Nemesis has been described as the daughter of Oceanus or Zeus, but according to Hyginus she was a child of Erebus and Nyx. She has also been described, by Hesiod, as the daughter of Nyx alone. In the Theogony, Nemesis is the sister of the Moirai (the Fates), the Keres (Black Fates), the Oneiroi (Dreams), Eris (Discord) and Apate (Deception) In some metaphysical mythology, Nemesis produced the egg from which hatched two sets of twins: Helen of Troy and Clytemnestra, and the Dioscuri, Castor and Pollux. While many myths indicate Zeus and Leda to be the parents
Castor et Pollux Castor et Pollux Castor et Pollux ("Castor and Pollux") is an opera by Jean-Philippe Rameau, first performed on 24 October 1737 by the Académie royale de musique at its theatre in the Palais-Royal in Paris. The librettist was Pierre-Joseph-Justin Bernard, whose reputation as a salon poet it made. This was the third opera by Rameau and his second in the form of the "tragédie en musique" (if the lost "Samson" is discounted). Rameau made substantial cuts, alterations and added new material to the opera for its revival in 1754. Experts still dispute which of the two versions is superior. Whatever
