These wonderful rock art paintings of everyday life were created 7000 to 10,000 years ago at Tassili-n-Ajjer, in the Sahara Desert of Algeria. Five periods of rock art are shown in this screensaver: the Balbalus (hunter or wild fauna) period, the Round Head period of Martian-like figures, the Bovidian cattle herder period, the Horse period, and the Camel period. Many of these painting were made during the African Aqualithic era, when the Algerian area was much wetter than it is today. 48 images.
