 | | Petroglyphs (rock carvings) are more widespread than pictographs (rock paintings), which are preserved chiefly in dry regions, inside caves, and under overhanging cliffs. |
 | | Whatever the motive, the prehistoric artist often reached great aesthetic heights, as in the Paleolithic art of Western Europe, the rock figures attributed to the San of S Africa, and the Tassili cliff paintings discovered in the central Sahara that suggest that this was once a fertile area. |
 | | The paintings, made with charcoal and earth pigments mixed with grease, gum, or water, vary from crude outlines to fully developed polychrome compositions. |
