The Capitoline Pythagoras (this page’s avatar type) is a later portrait, not a photograph from life. Access to a face-type is a modest learning path.
Context
A Roman marble is not a 6th-century likeness of verified identity.
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
A Capitoline herm is not an autograph.
