Pythagoras is known as the father of philosophy. He was one of the most influential figures of all time. While he lived some 2,600 years ago, he is as much a part of today's world as he was of classical Greece. Illustrated with diagrams by Stanley, modern geometrical figures, and ancient coins from Pythagoras' day, this book is an excellent introduction to a seminal figure of world history. There is crimping to the fore edge of the front cover. Otherwise a good, clean and tight copy.
