Earlier writing carriers

Cave designs are the oldest documents, which humans with pigment color drew on an underground. The Sumerer, the carriers of the oldest well-known advanced culture, wrote since approximately 3200 v. Chr. with cuneiform script on soft clay/tone boards, which are delivered until today partially, because they were burned by coincidences. Also made of Egypt writing carriers from inorganic materials are well-known, for example the splendor pallet of the king Narmer (3100 v. Chr.) from Speckstein.Es became already organic writing carriers such as leather, Pergament, wood, crust, papyrus (Egypt starting from approx. 3000 v. Chr.) and paper uses, from which we know however only from designs on more durable material (about rock).
