EOS was the rosy-fingered goddess of the dawn. She and her siblings Helios (the Sun) and Selene (the Moon) were numbered amongst the second-generation Titan gods. Eos rose up into the sky from the river Okeanos at the start of each day, and with her rays of light dispersed the mists of night.

She was sometimes depicted riding in a golden chariot drawn by winged horses, at other times she was shown borne aloft by her own pair of wings.

Eos had an unquenchable desire for handsome young men, some say as the result of a curse laid upon her by the goddessAphrodite.
