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 and Pollux was very ancient: a uniquely Spartan aniconic representation of the Tyndaridai was as two upright posts joined by a cross-bar; as the protectors of the Spartan army the "beam figure" or "dókana" was carried in front of the army on campaign. Sparta's unique dual kingship reflects the divine influence of the Dioscuri. When the Spartan army marched to war, one king remained behind at home, accompanied by one of the Twins. "In this way the real political order is secured in the realm of the Gods". Their "herōon" or grave-shrine was on a mountain top at Therapne across the Eurotas
