Read the full account

Stanford’s Pythagoras entry and St Andrews MacTutor state that later lives, not letters or a household register, are what remain. Opacity of a famous sage is the path: later states cannot audit a diary because there is none.

Context

High confidence on the gap. This is not GDPR. It forbids a fake 570 BCE birth Fact on this page.

Pythagoras is not the sole author of every later object, law, or museum label that uses the name. Shared work with courts, excavators, printers, spouses, officials, and later states does not erase a documented role, and it does not make an ancient person the signer of a twentieth-century statute.
