The Ancient art of dowsing has been practiced throughout millennia, although the names used to identify it may have changed in different cultures and eras, the techniques have not.
In this vein, in 1949, a party of French explorers (while searching for evidence of lost civilizations in the Atlas Mts. of North Africa) stumbled upon a massive system of caverns known as the Tassili Caves, wherein many of the walls were covered with marvelous pre-historic paintings. Among the many fascinating wall murals, not only did they locate an art gallery devoted exclusively to the depictions of spacecraft and ET’s, they also found a remarkable huge wall painting of a dowser, holding a forked branch in his hand searching for water, surrounded by a group of admiring tribesmen. These wall murals were carbon dated and found to be a least 8000 years old.
