Rock art occurs throughout the world, and is one of the most fascinating aspects of our human past.
The art consists of carvings and paintings on rock, which are classified as petroglyphs and pictographs, respectively. Researchers have long believed that some of the rock art occurrences depict stories from the past, although deciphering the stories is almost impossible in most cases. At some sites, however, there are recorded accounts by the descendants of those who created the rock art, collaborating the interpretation of the rock art as story. A few have gone as far as to propose the existence of rock art languages which they claim to have deciphered. Such claims are disputable as they are based on intuitive assumptions not supported by scientific or ethnographic evidence.
