His only preserved writings are some notes contained in manuscripts of Plato's dialogues. He has been called a \"true Renaissance man\" and \"the cleverest man in Byzantium in the 9th century\". He was archbishop of Thessalonica and later became the head of the Magnaura School of philosophy in Constantinople, where he taught Aristotelian logic."
