For a few years a great illustrator like Sacha Gepner, and a renown paleoanthropologist such as Yves Coppens (Lucy’s discoverer) have worked alongside to create a documentary children series on the origins of man and on the evolution of the human kind in Prehistory. Once the series was over, Sacha Gepner decided to tell the story of a cave boy of some ten thousands of years ago (the Cro-Magnon period, the Homo sapiens sapiens one). This story is about a group of hunters, in a period when men lived in small groups and moved continuously to follow the game, finding shelter in big caves near which they built their huts. The first worry of these men was to teach their sons the art of hunting, the most important activity to have food for their nourishing and skins to cover themselves. For this reason when a child can’t hunt nor kill animals, for he loves them so much, it is understandable the consequent anger of his father. Of course this boy is our protagonist: little Cro-Magnon also known as Cro-Mignon, whose best friend are the animals even the wild ones, and is totally at ease in the wonderful world of the caves and of the forest. His problems will start when his father forces him to hunt, leading him into a situation in which only his animal friends can help him. Yves Coppens, due to his great friendship with Sacha Gepner revised this tale and, in specific, contextualized it from the point of view of prehistory. Thus this book is a compelling fantasy tale in which the reader can also learn precisely the life of our ancestors.
