The cave in the Tsodilo hills has a rock with a marked resemblance to a python's head, The Times of London reported. The rock has manmade marks on it and a hiding place behind it that could have been used by a shaman appearing to speak for the python.
Sheila Coulson of the University of Oslo said the indentations on the rock in daylight look like scales. In the light of a fire, the snake appears to move.
