Engraved Rock of Kopong (Azurite):

These South African graffito engravings are believed by some to be the handiwork of herd boys while others say they played a part in religious practices, for healing, and other shamanistic activities such as out-of-body travel and the control of large game animals. We like the herd boy theory.
