Nikephoros Blemmydes

Nikephoros Blemmydes, who lived from 1197 to 1272, was a Byzantine scholar born in Constantinople who relocated to Asia Minor after the Fourth Crusade's conquest of the city in 1204 and received a broad education spanning medicine, philosophy, theology, mathematics, astronomy, logic and rhetoric. He became a prominent voice in theological debate between the Eastern Orthodox and Roman Catholic churches over the procession of the Holy Spirit, arguing for the Western position, and he established his own school, tutoring students including the future Emperor Theodore II Laskaris and the historian George Akropolites. A significant collector of classical texts, he later founded a monastery in Ephesus where he spent his final decades, and his surviving works include an autobiography, several epitome texts, and treatises on spiritual virtue, physics and royal governance.
