The first unabridged translation into American English, and the first to take into account the wealth of Thucydidean scholarship of the last half of the twentieth century, Steven Lattimore’s translation sets a new standard for accuracy and reliability. Notes provide information necessary for a fuller understanding of problematic passages, explore their implications as well as the problems they may pose, and shed light on Thucydides as a distinctive literary artist as well as a source for historians and political theorists.
