Historically, it was Pythagoras' experiment that was considered the authority - akthough Pythagoras was said to have gleaned his knoweldge from Egypt.
We don't have those Egyptian sources, nor were they used by Renaissance folk when they rediscovered Socrates, Plato and Aristotle and kicked off the explosion of Western Civ we still live in - although we seem to hate it now and seek to discredit whenever possible.
Now how about Vincenzo being the first Rock'n"Roll dude who cahnged history, music, culture and science by doing repeatable experiments (!! A Big Deal !!) rather than relying on theory?
His damn luitye didn't sound right, and hios sources were Pythagoras for theory and Arsitotle's logic and demonstration.
