[FAMILY.FTW]
AETHRA (2), one of the Oceanides, was the mother of the Hyades and Hesperides by Atlas. The Pleiades have also been called her daughters, although their mother is usually called Pleione, hence their name. [Ovid, Fasti 5.169; Eustathius on Homer's Iliad 1155.]
PLEIONE was one of the Oceanides and mother of the Pleiades by Atlas. Atlas was the son of Iapetus and Clymene, and leader of the Titans in the war against Zeus and the Olympians. He was condemned to bear the heavens on his head and shoulders. Pleione had to share him with Aethra, who according to some, became the mother of the Hyades and Hesperides by him. He had children by other women as well. The Pleiades mated with gods for the most part, but interestingly only one of Pleione's grandchildren--Hermes--was one of the immortal Olympian gods. An interesting question might be why he was different, since Zeus, his father, had sons by two of the other Pleiades.
