PT Petroglyph™ was designed by Ekaterina Kulagina and licensed by ParaType in 2002. The type was created on the basis of petroglyphs (rock-carvings) that are known in 77 countries. They remained in a form of geometrical drawings in the caves of North Spain and France. Scientists claim that the radial spread-out of circles or center-pointed circles that are usually depicted show the development of solar symbolism at that period of time. We know for sure that such mysterious signs as drawings carved on rocks already existed 40 centuries ago.
