Iamblichus' Life of Pythagoras · Iamblichus1 of 8
  1. Key idea 1

    A teacher becomes a living model

    Iamblichus presents Pythagoras as more than a thinker with ideas to explain. He makes the teacher's life a guide to wisdom, gathering accounts of his origins, travels, habits and powers. Philosophy appears here as a discipline of the soul.

    Writing some eight hundred years after Pythagoras, Iamblichus draws on older writers and school tradition. His portrait therefore shows both how later readers remembered Pythagoras and what Iamblichus himself wanted philosophy to accomplish: a life shaped by the wisdom it teaches.

Who it’s for

For readers who love ancient philosophy, early Greek religion, music and number, or stories of how a school builds a community around one teacher.

What this book is

Iamblichus' Life of Pythagoras is a portrait of the Greek thinker who gave his name to the Pythagorean way of life. It was written by Iamblichus, a Neoplatonist philosopher from Syria who worked in the late Roman world. He was a pupil in the school of Porphyry, and he wrote this book as the opening of a larger series on Pythagorean philosophy. It is less a modern biography than a guide to living, built around one teacher who is shown as a model of wisdom.

Iamblichus lived some eight hundred years after Pythagoras, so he drew on older writers and on school tradition. He gathers stories of the sage's birth, his travels, his teaching in Italy, his rules for daily life and his strange powers. You get the picture of Pythagoras that later ancient readers held, which shaped how Europe remembered him for centuries. You also see how a philosopher of Iamblichus' own day wanted philosophy to work, as a discipline of the soul. Let us begin with the man himself, his birth and his long education.

Key point 1 of 6

A wise man born under divine signs

Iamblichus opens with the birth of Pythagoras at Sidon in Phoenicia, during his father's travels for trade. The family's home is the island of Samos, where the boy grows up. His father is named Mnesarchus, and the book gives the family a distinguished and partly sacred background. A prophecy at Delphi is said to have foretold that the child would bring great good to humankind. Iamblichus presents the boy's soul as one sent from Apollo to help humankind.

The author leaves no doubt about his own answer. For him, Pythagoras is closer to a gift from the gods than to a normal human being. Later in the book he even reports that some people thought him a son of Apollo. Iamblichus does not argue the point like a modern historian. He tells the tradition, and he expects the reader to take the spirit of it.

The early chapters also show a boy of unusual gravity and self-command. Pythagoras is gentle with others and serious in his habits. He wins the respect of elders while still young. These details set up the pattern for the whole book. The character of the teacher is the main proof of his teaching.

For a reader today, this first section shows how ancient writers built a hero. They placed the great person at the center of the world, with signs at birth and wonders in youth. Seen that way, the stories say what Iamblichus valued. He wanted a philosopher whose life and ideas were one thing.
