In Hesiod's Theogony, Nyx is born of Chaos. With Erebus, Nyx gives birth to Aether and Hemera. Later, on her own, Nyx gives birth to Moros, the Keres, Thanatos, Hypnos, the Oneiroi, Momus, Oizys, the Hesperides, the Moirai, Nemesis, Apate, Philotes, Geras, and Eris. '' or Selene In his description of Tartarus, Hesiod locates there the home of Nyx, and the homes of her children Hypnos and Thanatos. Hesiod says further that Nyx's daughter Hemera left Tartarus just as Nyx entered it; continuing cyclicly, when Hemera returned, Nyx left. This mirrors the portrayal of Ratri in the Rigveda, where she works in close cooperation but also tension with her sister Ushas.
Homer
At Iliad 14.249–61, Hypnos, the minor deity of sleep, reminds Hera of an old favor after she asks him to put Zeus to sleep. He had once before put Zeus to sleep at the bidding of Hera, allowing her to cause Heracles great misfortune. Zeus was furious and would have smote Hypnos into the sea if he had not fled to Nyx, his mother, in fear. Homer goes on to say that Zeus, fearing to anger Nyx, held his fury at bay and in this way Hypnos escaped the wrath of Zeus by appealing to his powerful mother. He disturbed Zeus only a few times after that always fearing Zeus and running back to his mother, Nyx, who would have confronted Zeus with a maternal fury.
Others
Nyx took on an even more important role in several fragmentary poems attributed to Orpheus. In them, Nyx, rather than Chaos, is the first principle from which all creation emerges. Nyx occupies a cave or adyton, in which she gives oracles. Cronus – who is chained within, asleep and drunk on honey – dreams and prophecizes. Outside the cave, Adrasteia clashes cymbals and beats upon her tympanon, moving the entire universe in an ecstatic dance to the rhythm of Nyx's chanting. Phanes – the strange, monstrous, hermaphrodite Orphic demiurge – was the child or father of Nyx. Nyx is also the first principle in the opening chorus of Aristophanes' The Birds, which may be Orphic in inspiration. Here she is also the mother ofEros. The theme of Nyx's cave or mansion, beyond the ocean or somewhere at the edge of the cosmos may be echoed in the philosophical poem of Parmenides. The classical scholarWalter Burkert has speculated that the house of the goddess to which the philosopher is transported is the palace of Nyx; this hypothesis, however, must remain tentative. In some accounts, the goddess of witchcraft, Hecate was also called the daughter of Night. at the side of the ProphetIsaiah
Cult
There was no known temple dedicated to Nyx, but statues are known to have been made of her and a few cult practices of her are mentioned. According to Pausanias, she had an oracle on the acropolis at Megara. Pausanias wrote : More often, Nyx was worshipped in the background of other cults. Thus there was a statue called "Night" in the Temple of Artemis at Ephesus. The Spartans had a cult of Sleep and Death, conceived of as twins. Cult titles composed of compounds of nyx- are attested for several deities, most notably DionysusNyktelios "nocturnal" and AphroditePhilopannyx "who loves the whole night". Roman authors mentioned cult practices and wrote hymns in her honor. Ovid wrote: "May 9 Lemuria Nefastus. You ancient rite will be performed, Nox Lemuria; here will be offerings to the mute dead", and she is also mentioned by Statius:
Astronomy
In 1997, the International Astronomical Union approved the name Nyx for a mons feature on the planet Venus. Nyx Mons is located at latitude 30° North and longitude 48.5° East on the Venusian surface. Its diameter is 875 km. On June 21, 2006, the International Astronomical Union renamed one of Pluto's recently discovered moons Nix, in honor of Nyx. The name was spelled with an "i" instead of a "y", to avoid conflict with the asteroid3908 Nyx.
