Theodore the Studite

Theodore the Studite (Medieval Greek: Θεόδωρος ὁ Στουδίτης; 759–826), also known as Theodorus Studita and Saint Theodore of Stoudios/Studium, was a Byzantine Greek monk and abbot of the Stoudios Monastery in Constantinople. He played a major role in the revivals both of Byzantine monasticism and of classical literary genres in Byzantium. He is known as a zealous opponent of iconoclasm, one of several conflicts that set him at odds with both emperor and patriarch. Throughout his life he maintained letter correspondences with many important political and cultural figures of the Byzantine empire; this included many women, such as the composer and nun Kassia, who was much influenced by his teachings.
