The Pleiades ( or ; , Modern ), companions of Artemis, were the seven daughters of the titan Atlas and the sea-nymph Pleione born on Mount Cyllene. They are the sisters of Calypso, Hyas, the Hyades, and the Hesperides. The Pleiades were nymphs in the train of Artemis, and together with the seven Hyades were called the Atlantides, Dodonides, or Nysiades, nursemaids and teachers to the infant Bacchus.
