Works of Theon of Smyrna were strongly influenced by Pythagoras, the Greek philosopher and mathematician known for what?
Pythagoras Pythagoras of Samos ( ; ; Greek: Πυθαγόρας ὁ Σάμιος  "Pythagóras ho Sámios"  "Pythagoras the Samian" , or simply Πυθαγόρας ; Πυθαγόρης in Ionian Greek; 495 BC ) was an Ionian Greek philosopher, mathematician, and putative founder of the Pythagoreanism movement. He is often revered as a great mathematician and scientist and is best known for the Pythagorean theorem which bears his name.
Eurytus (Pythagorean) Eurytus ( ; Greek: Εὔρυτος ; fl. 400 BC), was an eminent Pythagorean philosopher who Iamblichus in one passage describes as a native of Croton, while in another, he enumerates him among the Tarentine Pythagoreans. He was a disciple of Philolaus, and Diogenes Laërtius mentions him among the teachers of Plato, though this statement is very doubtful. It is uncertain whether Eurytus was the author of any work, unless we suppose that the fragment in Stobaeus, which is there ascribed to one Eurytus, belongs to this Eurytus.
