Hemera

Hemera was the personification of day and was one of the Greek primordial deities. She was the goddess of the daytime and, according to Hesiod, the daughter of Erebus and Nyx. Bacchylides states that Nyx and Chronos are the parents, but Hyginus in his preface to the Fabulae mention Chaos as the single parent.

She was the female counterpart of her brother and consort, Aether, but neither of them figured actively in myth or cult. Hyginus lists their children as Uranus, Gaia, and Thalassa, while Hesiod only lists Thalassa.

Her Roman equivalent was Dies.
