First described in the 1920s, thee paintings are found mainly in central Tanzania’s Kondoa Province at the western edge of the Great Rift Valley. The art includes early, fairly large, naturalistic images of animals with occasional geometric patterns while later images depict people and animals apparently involved in hunting and domestic scenes. People are often drawn wearing skirts with strange hairstyles and / or headdresses as well as body decoration and are frequently shown holding bows and arrows.
The paintings were first studied extensively by Mary and Louis Leakey in the early 1950s. Just north of Kondoa the Hazda people still painted on rock shelters well into the 20th century.
