The essence of every rock art study must be the image. In most cases the image that we observe is not quite the same as manufactured and/or intended by prehistoric people. It is altered by weathering, erosion and all sorts of anthropic activities. Yet, the resulting image is the only source to use. The best thing to do is to photograph the image, but if one makes a drawing of the image, it should be as correct as possible. Yet, many rock art researchers produce and publish drawings that are not correct. Consequently, their interpretations will be incorrect. This study discusses some examples of incorrect drawings and offers some recommendations.
