Named after a site in southern Algeria where engravings were first recognised as being part of a style, this art is found throughout the central and western Sahara but especially in south-eastern Morocco and in north-eastern Niger (Djado Plateau). The art is characterised by cleanly and simply incised outlined images with polished lines as well as schematic designs and geometrics.
Sometimes a second smaller image can be seen inside the main outline. These images vary considerably and the animal images are dominated by representations of rhino. Unfortunately thieves have stolen and vandalized huge numbers of engravings in this region, selling them to foreign collectors and dealers who usually whisk them away to Europe via the straits of Gibraltar. Neolithic arrowheads (above) are found in the desert and are also bought by collectors.
