Historians universally agree that Thucydides was the greatest historian who has ever lived, and that his story of the Peloponnesian conflict is a marvel of forensic science and fine literature. That such a triumph of intellectual accomplishment was created at the end of the fifth century B.C. in Greece is, perhaps, not so surprising, given the number of original geniuses we find in that period. But that such an historical work would also be simultaneously acknowledged as a work of great literature and a penetrating ethical evaluation of humanity is one of the miracles of ancient history.
