Prehistoric methods of diagnosis and treatment
Compare these two images of shamans. The first is a 19th-century drawing of a Native American shaman, the other is a replica of a 20,000-year-old cave painting.

This cave painting may show a shaman, whose ideas may have been similar to those held by Native Americans of the 19th century. All theories about paintings such as this, however, are pure guesswork.
