Republication of David Lowenthal's elegant translation of Montesquieu's neglected study of the Romans--an indispensable source for understanding the philosopher's treatment of Rome in The Spirit of the Laws--makes the book available to a new generation of English-language readers. Lowenthal's perceptive introduction and useful notes also deserve the attention of those who can read Montesquieu in the original French. --James W. Muller, University of Alaska, Anchorage
