Nyx is the personification of the night, a shadowy figure that stood at or near the beginning of creation.
In Hesiod's Theogony, Nyx is born of Chaos and with Erebus (Darkness), she gives birth to Aether (Brightness) and Hemera (Day). Later, she gives birth to Moros (Doom, Destiny), Ker (Fate, Destruction, Death), Thanatos (Death), Hypnos (Sleep) and Oneiroi (Dreams). Nyx is the first principle from which all creation emerges, a primordial figure of such exceptional power and beauty, that she is feared by Zeus himself. In Greece, Nyx was only rarely the focus of cults, she had not a large number of devotees, but those few who worshiped her, she granted the gift of prophecy, to see beyond the night of the present.
Everything comes from the night, the darkness, the void. This vacuum, represents for us the unconscious, that is hidden from the eyes, and that must be examined to bring out the whole. Everything already exists, we find it and find it again.
In his description of Tartarus, Hesiod locates there the home of Nyx and her children Hypnos and Thanatos. Hesiod says further that Hemera (Day), left Tartarus just as Nyx entered it; continuing cyclicly, when Hemera returned, Nyx left.
Life, time and death originate and are governed by the same principle of endless becoming.
The Shapeshifting Myth
The other soul of Nyxo belongs to the Danube, where, according to the German epic Nibelungenlied, act the Nix (male) and Nixe, types of river merman and mermaid who may lure men to drown: The females are beautiful women with the tail of a fish, while the males are creatures that can assume many different shapes, and may not have any real form. This reminds us the talent for mimicry of the alien creature in John Carpenter's movie "the Thing", a monstrous entity in perpetual motion, unfixed in its identity.
It is the unknown made flesh, a reminder of the chaos from which we arose.
The shapeless uncertainty of endless becoming.
