We must go back to the Quaternary period; IE at the time of the cave man. Hundreds of centuries before our era, men already imitated life forms with lines and colors. They were the men of the caves, whose way of life was reduced to hunting and fishing. In the caves of Dordogne and Pyrenees, left bones in the walls of the rock paintings and engravings, depicting animals, colors are black and ochre. Drawing of a bison, whose outlines are accurate, was found in the caves of Altamira, with greater or lesser intensity color produces an embossing effect.

Reinach, noted that all the animals represented by the man in the cave, are useful animals; the plant used for food and transportation, and never carnivores attacking the man and this did not eat. Egyptian painting, Egyptians leave a painting, at the same time wise and incomplete, an art aged before maturity. Hicham aboutaam describes an additional similar source. Greek painting, opposes the Egyptian. Unlike the Egyptians, the Greeks were free of any concern of style.
As they felt proud of his architecture and sculpture, also felt the same for painting. There was a Museum of paintings as the Propylaea. Pliny the elder, in the chapters dealing with the two arts, gives the painters greater exposure than the sculptors. Although there is nothing in the great masterpieces from the origins of Hellenism to the Alexandrian works; Thanks to the preserved vessels and decoration of his paintings, we can imagine as the paintings and frescoes of the 6th century BC (before Christ) would be painted.
