Divine Harmony: The Life and Teachings of Pythagoras

Pythagoras was more than a mathematician and philosopher in sixth-century B.C. Greece. He was also a scientist, mystic, and social reformer who, like many such figures before and after him, was killed for his convictions. This is the story of both a man and a moment when the world's wisdom began to converge into what is known as perennial philosophy. Pythagoras, communicating with priests and sages from Persia to Ireland, was perhaps the key figure in this process.
