Allan Gilbert is unquestionably the most accurate and reliable translator of Machiavelli into English; the publication of this edition is an altogether happy occasion. Students of the history of political thought owe a particular debt of gratitude to Allan Gilbert."—Dante Germino, The Journal of Politics

"A most remarkable achievement."—Felix Gilbert, Renaissance Quarterly
