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.
Theodorus of Cyrene Theodorus of Cyrene (Greek: Θεόδωρος ὁ Κυρηναῖος ) was an ancient Libyan Greek and lived during the 5th century BC. The only first-hand accounts of him that survive are in three of Plato's dialogues: the "Theaetetus", the "Sophist", and the "Statesman". In the former dialogue, he posits a mathematical theorem now known as the Spiral of Theodorus.
