The Pleiades in the "Salle des Taureaux", grotte de Lascaux. Does a rock picture in the cave of Lascaux show the open star cluster of the Pleiades at the Magdalénien era (ca 15.300 BC?"

The cave of Lascaux is famous for its prehistoric paintings and above all for is magnificent portrayals of animals in the "Salle des Taureaux". Although the animals receive a great deal of attention during the guided tours, the sign-like shapes which are also depicted, are mostly passed over. But the puzzle surrounding one of these figures might now have been solved, thereby throwing light on the painting beneath it. The group of spots floating above the back of the largest Aurochs might represent the open cluster of the stars - the Pleiades (M 45/NGC 1432; 1^m5), which lie above the constellation of the bull (Taurus).
