In Greek mythology, Nyx (Νύξ, "night", Nox in Roman translation) was the primordial goddess of the night. A shadowy figure, Nyx stood at or near the beginning of creation, and was the mother of personified gods such as Hypnos (sleep) and Thanatos (death). Her appearances in mythology are sparse, but reveal her as a figure of exceptional power and beauty.

Role in myth and literature


In Hesiod's Theogony, Nyx is born of Chaos; her offspring are many, and telling. With Erebus the deity of shadow and darkness, Nyx gives birth to Aether (atmosphere) and Hemera (day). Later, on her own, Nyx gives birth to Momus (blame), Moros (doom), Thanatos (death), Hypnos (sleep), Charon (the ferryman of Hades), the Oneiroi (dreams), the Hesperides, the Keres and Moirae (Fates), Nemesis (retribution), Apate (deception), Philotes (friendship), Geras (age), and Eris (strife). In his description of Tartarus, Hesiod says further that Hemera (day), who is Nyx's daughter, left Tartarus just as Nyx entered it; when Hemera returned, Nyx left. This mirrors the portrayal of Ratri (night) in the Rigveda, where she works in close cooperation but also tension with her sister Ushas (dawn).


In Book 14 of Homer's Iliad, there is a quote by Hypnos, the minor god of sleep, in which he 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 (who was returning by sea from Laomedon's Troy) great misfortune. Zeus was furious and would have smitten Hypnos into the sea if he had not fled to Nyx, his mother, in fear. Hypnos 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. 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.

Other Greek texts

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. Nyx occupies a cave or adyton, in which she gives oracles. Cronus – who is chained within, asleep and drunk on honey – dreams and prophesies. 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' Birds, which may be Orphic in inspiration. Here she is also the mother of Eros. In other texts she may be the mother of Charon (with Erebus), and Phthonus "envy" (with Dionysus).

The theme of Nyx's cave or mansion, beyond the ocean (as in Hesiod) or somewhere at the edge of the cosmos (as in later Orphism) may be echoed in the philosophical poem of Parmenides. The classical scholar Walter 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.

There is also rumor that Nyx gave birth to her reincarnation, a son whose name would also be Nyx. But she gave birth to twins, having a daughter as well, who was named Hemera, "Day". The text implied that Hemera was not the sister of Aether, but the sister of Nyx's reincarnation.

Role in society

Cults of Nyx

In Greece, Nyx is only rarely the focus of cults. According to Pausanias, she had an oracle on the acropolis at Megara.[1]

More often, Nyx lurks in the background of other cults. Thus there was a statue called "Nyx" in the Temple of Artemis at Ephesus. The Spartans had a cult of Sleep and Death, conceived of as twins.[2] Cult titles composed of compounds of nyx- are attested for several gods, most notably Dionysus Nyktelios "nocturnal"[3] and Aphrodite Philopannyx "who loves the whole night".[4]

Astronomy and planetary nomenclature

On June 21, 2006, the International Astronomical Union renamed one of Pluto's recently discovered moons (S/2005 P 2) to Nix, in honor of Nyx. The name was spelled with an "i" instead of a "y", to avoid conflict with the asteroid 3908 Nyx.

In 1997, the International Astronomical Union approved the name Nyx for a mons (mountain/peak) feature on the planet Venus. Nyx Mons is located at 30 degrees north latitude, and 48.5 degrees longitude on the Venusian surface. The feature possesses a diameter of 875 km, and is attributed to Nyx. A map of Nyx Mons on Venus can be viewed at Map of Nyx Mons – V9 Quad – Bell Regio (1.1 Megabyte).
