Archaeology Archaeologists mapping their finds at Pachacamac, Peru, an Indigenous town occupied from approximately 200 bce to 1532 ce, when it was sacked by conquistadors under the command of Francisco Pizarro.

The Lascaux cave was discovered in September 1940 by four teenage boys who were playing in the woods near Montignac, France. The discovery occurred when the boys' dog disappeared down a hole, which they soon realized served as the entrance to a cave.12

Upon entering, the group unwittingly stumbled upon one of the most significant collections of prehistoric art ever found, featuring approximately 600 paintings and 1,500 engravings. Following the discovery, the site was first studied by the French archaeologist Henri Breuil. Due to the ongoing war, a detailed examination of the site was initially delayed, but the cave was eventually opened to the public in 1948.12
