Maybe its because I'm on mobile, but your link brings me to a faculty page and nothing there suggests Pythagoras wasn't a person. I even went through the syllabus of the most closely related of their past lectures (a quick history of ancient mathematics and mathematical ideas) and I quickly realized that I don't even know which book to read to try find anything related to Pythagoras' existence. Is there a specific piece of text I could read that would verify your claim?
