Cave painting is a form of rock art which archaeologists study. Some of my favorite examples of prehistoric art are the Lascaux cave paintings, found in southwest France. This cave site is home to multiple sections, each with paintings of animals, humans, and geometric shapes. The images are believed to be for ritual purposes and were painted with mineral pigments.
