The Pleiades were seven mountain nymph daughters of the Titan Atlas. Their leader was Maia, the mother of Hermes by Zeus. Five of the others were also loved by gods, becoming ancestresses of various royal families including those of Troy and Sparta. When they were pursued by the lustful giant Orion, Zeus set them amongst the stars as the seven-starred constellation Pleiades. Their name was derived from the Greek word pleiôn, meaning “plenty.”
