Claude Senac's story “The Caves of the Red River” is a fascinating story of Num, the fourteen-year-old son of the leader of one of the Cro-Magnon tribes, who lived on the territory of what is now France twelve to fifteen thousand years ago. The story of A. M. Linevsky “Leaves of a Stone Book”, which tells about events three to four thousand years ago, tells about the fate of the seventeen-year-old sorcerer Llok. Historical stories about primitive people are not pure fiction, but a true story based on three sources: archaeological data from excavations of burial grounds and settlements of ancient people, rock carvings - petroglyphs and rich ethnographic material from the life of backward tribes and peoples.
