Hemera

Hemera was a Greek primordial goddess. In Roman mythology, Hemera was known as Dies.

Abode
Hemera was the primordial goddess of the day. Hesiod describes her as a divine substance, rather than a goddess.

Parentage
Hesiod considers Hemera to be the daughter of Erebus and Nyx, and therefore the sister of her husband, Aether. Bacchylides considers Hemera to be the daughter of Chronus and Nyx. Hyginus considers her to be the daughter of Chaos and as the sister of Erebus and Nyx.

Day and Night
At dusk, Nyx would leave her home in Tartarus and she would draw the mists of Erebus across the sky in order to block out the light of Aether and to bring night upon the world. When Nyx returned to her home, Hemera would leave the house that they shared. Hemera would then scatter the mists and the light of Aether would again shine down upon the world, bringing back the day.
