African Writing Systems: Rock Arts
Among the earliest writing systems of Africa are the engravings and paintings on rocks throughout the continent of Africa. There are over one million such sites in Africa, some as old as 10,000 years. Ancient engravings and paintings on rocks are regarded as Africa's earliest historical documents. The engravings and paintings are meaningful symbols to represent the deeds and imaginations of our ancestors. They are also pointers to aspects of the lives of African peoples during the hunting and gathering age.
Rock art is found in the high plateaus and uplands of Africa, located in caves or cliffs on the edges of the uplands. Deserts such as the Sahara contain much art due to the past wet and green conditions of the desert and the preservation effects of dry air.
Among the most important sites of rock art in Africa are:
1. The Sahara: Tassili N'Ajjer of Algeria, Southern Morocco, Fezzan, Libya; Nir and Te'ne're' of Niger; Tibesti of Chad; and Dhar Tichitt of Mauritania.
2. Eastern Africa: Tanzania and Highlands of Ethiopia.
3. Southern Africa: Orange Free State, the Vaal river, Transvaal, and the Cango caves of the Cape region.
African rock art can be categorized into five periods:
Giraffe: 30,000 to 9,000 years ago
Bubalus (Buffalo, Elephants, Rhinoceros): 9,000 to 6,000 years ago
Ox: 6,000years ago
Horse: 6,000 years ago
Camel: 2,500 years ago
Rock engravings are usually performed in softer sandstone by striking with hammer made of stone in order to generate grooves and depths of incisions. The rock pictures suggest a wide range of meanings and interpretations. Some are distinctively spiritual and others are depictions of athletic prowess or hunting skills. It is important to take into consideration the social and cultural context of the arts when interpretations are being made.
Paintings are done in either single color or multiple colors. Red and brown colors are produced from Iron oxide, white is produced from kaolin, animal droppings, and Zinc oxide, whereas the color black is produced from charcoal, ground bones, smokes and burnt fat. Brushes are made of animal hairs.
