Ancient testimonies
Sources on Pythagoras concern his teaching, community, transmigration of souls and reputation as a sage. Modern collections gather testimonies of different dates and reliability: they do not form a book by Pythagoras.
Understanding the text
Fifth- and fourth-century BCE authors are much closer than late imperial biographies. Even early sources must be read in their own contexts and for their own purposes.
Collected evidence about Pythagoras; no authenticated writing by his hand survives.

Soul
Testimonies connect Pythagoras with transmigration without preserving a treatise written by him. Identify the ancient source preserving the passage and distinguish its words from modern interpretation.
Community
Rules and practices attributed to followers reveal a collective tradition difficult to assign to one individual. Compare this idea with another witness: an isolated quotation does not automatically restore its lost context.
Mathematics
Discoveries are often attributed to the school; personal attribution to Pythagoras remains contested. Note what the document permits you to conclude and what remains a hypothesis about the philosopher’s thought.
