St Andrews MacTutor is a completed public-history-of-maths page that marks late sources. The dated carrier is that URL. Honesty about legend is an access path.
Context
A university history page is not Iamblichus, and not a birth certificate.
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.
Why it matters
MacTutor is a scholarly access path, not a Croton archive.

Named sage as heading of later school reports. Iamblichus, Euclid’s editors, and later math teachers publish the instrument.
