A fascinating portrait of the Pythagorean tradition, including a substantial account of the Neo-Pythagorean revival, and ending with Johannes Kepler on the threshold of modernism. ''This book, written by one of the world's leading authorities on ancient philosophy, combines a lucid overview of the broad sweep of the Pythagorean tradition, appropriate for readers new to the subject, with new scholarly insights, which will make it essential reading for scholars as well. There really is no comparable up-to-date volume available in English. It is a wonderful book.'' -- Carl Huffman, DePauw University
