Eos is the rosy-fingered goddess of the dawn. She and her siblings Helios (the Sun) and Selene (the Moon) are numbered amongst the second-generation Titan gods. Eos rises up into the sky from the river Okeanos at the start of each day, and with her rays of light disperse the mists of night. She is sometimes depicted riding in a golden chariot drawn by winged horses, at other times she is shown borne aloft by her own pair of wings.
Lethe is the river of forgetfulness. From it souls drink and forget their experiences upon being reincarnated. Lethe refers to a state of oblivion, a state of persistent drowsiness, and the term lethean characterizes anything that causes forgetfulness of the past.
