Pythagoras of Samos (US: , UK: ; Greek: Πυθαγόρας ὁ Σάμιος Pythagóras ho Sámios 'Pythagoras the Samian', or simply Πυθαγόρας; Πυθαγόρης in Ionian Greek; c. 570 – c. 495 BC) was an Ionian Greek philosopher and the eponymous founder of the Pythagoreanism movement. His political and religious teachings were well-known in Magna Graecia and influenced the philosophies of Plato, Aristotle, and, through them, Western philosophy. Knowledge of Pythagoras's life is largely clouded by legend and obfuscation, but he appears to have been the son of Mnesarchus, a seal engraver on the island of Samos.
