Sahara’s millenary history gives evidence of extreme climate periods, such as long dry spells, torrential rains but also evidence of the people who had chosen to live there. Almost 12000 years ago and after a period of great aridity, rain came again and gave life to this place. Thereby, people of the central Sahara in the districts of Tadrart Acacus and Messak of Libya, came together and created persistent and active communities, culturally accomplished. They defined themselves not only through their existence, but managed to express their everyday life and their primitive need for transcendence by the elaboration of a complex pictorial language. The walls of the rocks in which they found shelter, became centre of activity and conservation of knowledge through engraved images and rupestrian paintings, between the end of Pleistocene and throughout of Holocene until the desertification. Books made of stone through which human history manages to survive and display its intact magic until today.
