The french naturalist Georges Cuvier (1769-1832) became so famous with his works in comparative anatomy, vertebrate paleontology and geology that he inspired during his life and after, numerous artists, sculptors, painters, caricaturists and novelists. Honoré de Balzac, the great novelist, used the methods of comparative anatomy for studying and reconstructing the extinct species introduced by Cuvier to build the 137 fictions of his "Comédie Humaine" as a comparative anatomy of the different people of the French society of the first half of the nineteenth century. The name of Cuvier appear in many pages of Balzac’s novels as a great poet able to explore lost worlds.
