<i>Discourses on Livy</i> is the founding document of modern republicanism, and Harvey C. Mansfield and Nathan Tarcov have provided the definitive English translation of this classic work. Faithful to the original Italian text, properly attentive to Machiavelli's idiom and subtlety of thought, it is eminently readable. With a substantial introduction, extensive explanatory notes, a glossary of key words, and an annotated index, the <i>Discourses</i> reveals Machiavelli's radical vision of a new science of politics, a vision of "new modes and orders" that continue to shape the modern ethos. <br
