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 duty that Pollux faces: should he pursue his love of Telaira or rescue his brother? Of course, he chooses the latter. In the 1754 version, Dill remarks that that plot is more concerned with the tests that Pollux must face: he must kill Lynceus, persuade Jupiter not to oppose his journey into the Underworld, and persuade Castor not to accept the gift of immortality. While some scholars (such as Cuthbert Girdlestone, Paul-Marie Masson, and Graham Sadler) have assumed that the 1754 version was superior, Dill argues that Rameau made the changes of 1754 at a different point in his career.
