50 free Pythagoras trivia questions with answers — history quiz, new questions added Aug 2026.
This Pythagoras trivia quiz covers both the philosopher and the myth. It follows the son of a Samian gem-engraver who left his island around 530 BC, founded a secretive, ascetic community at Croton in southern Italy, taught that souls pass from body to body, and was credited in antiquity with the theorem, the sphericity of the Earth, the identity of the morning and evening stars and the music of the spheres. It also covers the strange rules of the brotherhood, the ban on fava beans, the tale of the blacksmiths' hammers, the golden thigh, the burning of the meeting house and the long afterlife of his ideas in Plato, Kepler, the Freemasons and the vegetarian movement. The easy questions are ones most people know: the island, the theorem, the triangle. The medium ones ask about his school, his doctrines, his legendary travels and his death. The hard ones dig into Pherecydes, Philolaus, the tetractys, Plimpton 322, the Porta Maggiore basilica and the trick cup that bears his name. It suits a maths class, a philosophy round or a pub quiz with a taste for the ancient world. Every answer has been checked against a reference encyclopaedia, and each question shows its explanation and citation once you have answered.
