Description

In the clear and unpolluted night skies of antiquity the Pleiades star cluster was an object of wonder and interest.

In Greek mythology, the Pleiades were seven sisters: Maia, Electra, Alcyone, Taygete, Asterope, Celaeno and Merope. Their parents were Atlas, a Titan who held up the sky, and the oceanid Pleione, the protectress of sailing.
