About this book
What if philosophy asks you to change not just your mind, but your whole way of life?
In Iamblichus' Life of Pythagoras, a teacher becomes the centre of a demanding way of living. Drawing on older writers and school tradition, Iamblichus traces Pythagoras from his childhood on Samos through his studies with Pherecydes, Thales and Anaximander to his teaching in southern Italy.
Writing some eight hundred years after Pythagoras, Iamblichus offers more than a life story. His portrait gathers rules for daily conduct, accounts of friendship and stories of strange powers. It shows how later ancient readers remember the sage, and how philosophy becomes, for Iamblichus, a discipline of the soul.

An oracle foretells the birth of Pythagoras
Iamblichus opens by calling on the gods, because he believes the philosophy of Pythagoras came from them. The island of Samos is the homeland, and the parents are Mnesarchus and Pythais.
Mnesarchus once went to Delphi and asked the god about his voyage to Syria. The oracle answered more than he asked. It said his wife was already with child and would bear a son who would surpass all others in beauty and wisdom and would help humankind. Mnesarchus named the boy Pythagoras, the one announced by the Pythian Apollo. Iamblichus rejects the idea that the god fathered him, but he insists the soul of Pythagoras came from the realm of Apollo.
