This anthology is the largest collection of ancient writings on Pythagoras ever to appear in the English language. Including four ancient biographies of Pythagoras and over 25 Pythagorean and Neopythagorean writings from the classical and Hellenistic periods. The overriding concern in these ancient writings is their premise that the universal principles of Harmony, Proportion and Justice govern the physical cosmos. This has become the standard reference book on Pythagoras, with an excellent introduction by a well know modern Pythagorean, David Fideler, supplying essential background material. Highly recommended.
