In 2013, the British Museum and the Trust of African Rock Art (TARA) launched The African Rock Art Image Project. A collaborative effort, the Project has collected and catalogued about 25,000 digital photographs of African rock art. These spectacular images include a variety of petroglyphs (rock engravings and carvings) and pictographs (rock paintings), including the oldest known piece of art work: tablets from Namibia that archeologists have dated as 26,000-28,000 years old. On this website, visitors can browse this collection by country, learn more about the history of rock art itself, and explore the origins of archeological investigations. Readers will find detailed explanations about how rock art was produced, how archeologists date rock art, and how rock art varies across regions. Visitors can also check out three-dimensional diagrams and short film clips where project specialists provide insights into a variety of art pieces.
