About the book: year / Scientists of the twenty-first century go back in time - to the Paleolithic era, twenty thousand years BC. The novel seems to follow a pattern - wise newcomers from a civilized era study a moderately wild Cro-Magnon tribe. But Farmer remains true to himself, turning the cliche inside out, and a trip to the past turns out to be just a springboard. The immortal guardian of human history, the Eternal Savage, his own descendant and ancestor (bearing a suspicious resemblance to Farmer's beloved Tarzan) uses the expedition to begin his journey and leaves the scientists a capsule with all the information he has collected over the millennia of his earthly journey.fantlab.ru
