Marc Azéma, a French archaeologist and filmmaker, has come up with a pretty novel theory. Maybe the earliest cave paintings, created some 30,000 years ago at sites like Chauvet, weren’t static creations. Maybe they were meant to show movement, to tell a sequential story. Maybe the cave paintings in France and Spain gave us our first animations, a prehistoric kind of cinema. The video above takes cave paintings from Lascaux, Les Trois-Frères, Chauvet and elsewhere, and shows how the images, if arranged sequentially, actually depicted motion. The audio report below, from PRI’s The World, tells you more about Azéma’s research.
