Hémerá

Hesiod's poem Theogonia ("On the Origin of the Gods" or also "The Birth of the Gods") describes the origin of Hemeras as follows: "In truth at first Chaos came to be, but next wide-bosomed Earth, the ever-sure foundation of all the deathless ones who hold the peaks of snowy Olympus, and dim Tartarus in the depth of the wide-pathed Earth, and Eros, fairest among the deathless gods, who unnerves the limbs and overcomes the mind and wise counsels of all gods and all men within them. From Chaos came forth Erebus and black Night; but of Night were born Aether and Day, whom she conceived and bore from union in love with Erebus ..."

The brother of Hémera was Aithér (eternal light). In later times her importance was associated with the goddess Éós (goddess of the morning reds).
