The historical memory of our civilization has always been a topic of vital importance to humanity in many periods of human development, so mechanisms such as writing, painting and film are created; In much we can say that more than communication mechanisms are a way to preserve the history of our humanity.
The cave paintings of “Tassili n’Ajjer” dating from 3000. C. and show a number of elements present in the environment in the region now known as the great Sahara desert. Representation in the rock helped the man in the understanding of many changes made in North Africa.
The finding of representations of animals that usually inhabit savannas is vital in understanding the sahara was once a great savannah where thousands of animals were grazing. The image shows examples of Bubalus antiquus in the Sahara.
One way or another our ancestors sought a mechanism by which they could recall some elements of the environment and the variety of food available (animals, plants and water) environmental hazards (volcanoes, dangerous animals and geography) and how proficiently with other individuals in the area. All these techniques used in the recordings performed in the caves which today we call cave paintings in this case “Tassili n’Ajjer” is a graphical database showing largely historical parts of a certain region, which time and climatic factors preceded by global warming have changed making it one of the largest deserts in the world.
Since ancient times communication and the historical foundations of our humanity have been a topic of vital importance to man and we can see in many of the plots (rock paintings) left in prehistory.
