This flat stone do not have grooves. It is, however, decorated on both faces with motifs that are not easy to identify and whose meaning remains uncertain. The archaeologists at the Jerf al-Ahmar site believe that the markings express some highly symbolic message. Certain researchers are even tempted to see a primitive form of writing in them. If this is the case, these recent finds could open a window onto the mental and imaginative world of one of the oldest human communities.
