In 1879, a group of explorers made an incredible find. They discovered paintings of remarkable beauty on the walls of a cave in Spain. Some scientists believed that these paintings were created by early humans from the Stone Age, between ten and thirty thousand years ago. Other scientists and the public did not believe the claim, but over the years, it was proven correct. Our ancestors had incredible artistic talents.
Most of the cave art that has been discovered has been found in Spain and France. A smaller number of such caves are located in Italy, Portugal, Russia, and other countries. Scientists believe that many more caves will be discovered in the ing years, and are concentrating their efforts on Africa and the area between Europe and Asia. These two regions of the world were, populated first by humans.
Cave art was carved or painted on the walls and roofs of caves, usually near the entrance. The entrance area was probably chosen to take advantage of daylight and to allow many people to view the paintings. In some cases, the art appears much deeper in caves and requires artificial light. Evidence suggests that the artists used torches or shallow bowls in which animal fat was burned.
