The Pleiades, 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. There is some debate as to the origin of the name Pleiades. Previously, it was accepted the name is derived from the name of their mother, Pleione. However, the name Pleiades may derive from πλεῖν(to sail) because of their importance in delimiting the sailing season in the Mediterranean Sea. (Wikipedia)
For Ernst eroticism was another way of entering the unconscious, of escaping from convention, and possibly of tweaking bourgeois taste. But he was aware that adult sexuality had its limits, as is apparent in the exquisite Approaching Puberty… (1921). A photograph of a nude, faceless girl floats in a blue space stratified by horizontal lines, suggesting water or the sky. A few strangely disparate forms surround the girl, and the short text at the bottom ends, “The gravitation of the undulations does not yet exist.” The title, this line, and the fact that the girl floats in space rather than standing on the ground – as most of Ernst’s figures do – suggests that he sees in pubescence a kind of weightless freedom. In a related but nonsexual image, an Untitled c. 1921 collage, four schoolboys peer out of their classroom (from which a wall is missing) at a vast blue sky in which a hot-air balloon floats. A schoolmaster stands alone and ignored at his desk; next to him one of the boys balances a giant pencil on a pointer. What’s learned in school, Ernst seems to say, is far less important than visions of the sky. (“Max Ernst’s Theater of Reveries” by Fred Camper on the Chicago Reader website)
