The greatest historian that ever lived." Such was Macaulay's assessment of Thucydides (c. 460 400 BC) and his history of the Peloponnesian War, the momentous struggle between Athens and Sparta that lasted for twenty seven years from 431 to 404 BC, involved virtually the whole of the Greek world, and ended in the fall of Athens. A participant in the war himself, Thucydides brings to his history an awesome intellect, brilliant narrative, and penetrating analysis of the nature of power, as it affects both states and individuals. Of the prose writers of the ancient world, Thucydides has had more lasting influence on western thought than all but Plato and Aristotle. This new edition combines a masterly new translation by Martin Hammond with comprehensive supporting material, including summaries of individual Books; textual notes; a comprehensive analytical index; an appendix on weights, measures and distances, money, and calendars; ten maps; an up to date bibliography; and an illuminating introduction by P.J. Rhodes.
