Hesiod's Theogony
A genealogy of the gods
Nyx (Night): The embodiment of night.
From Chaos, Erebus and Nyx were born.
Nyx and Erebus produced Aether (Brightness) and Hemera (Day).
From Chaos emerge Gaia (Earth), Tartarus (the Abyss), Eros (Love), Erebus (Darkness), and Nyx (Night), setting the stage for the creation of the cosmos and the gods.
