12 сентября 1940 года  найдены наскальные рисунки в пещере Ласко

On this day, four French boys played on the banks of the Weser and crawled into a hole beneath the roots of a tree fallen in the storm. There was a real cave. Having inspected its walls covered in unusual drawings, children ran back to the teacher. The first explorer of the Lascaux wall paintings was Henri Breuil, a professor in history of primitive society, who hid out in Perigord during the occupation of France. Today, the cave with unique paleolithic paintings is praised as the Sistine Chapel of the primitive painting. According to the researchers, these paintings date back to 15,000 B.C.
