The July/August 2013 issue of Minerva (The International Review of Ancient Art & Archaeology) is featuring a very interesting article by David Coulson, the leading photographer of African Rock Art, discussing the threats it is facing. Coulson’s Trust for African Rock Art wishes to create greater global awareness of the importance and endangered state of African rock art. It records the rock art heritage of the African continent and makes this information accessible online. In 2014, TARA’s digital rock art archive will become accessible through the British Museum’s global online collections, but for now many images can be consulted here (more than 1000 images and well worth a visit). Unfortunately no references to the rock art of the Dogon can be found on the website (yet).
UPDATE: for Dogon rock art, check this album with fantastic pictures by Huib Blom.
