John Italus or Italos (Greek: Ἰωάννης ὁ Ἰταλός, Iōánnēs ho Italós; Latin: Johannes Italus) was a neoplatonic[1][2] Byzantine philosopher of the eleventh century. He was Calabrian in origin, his father being a soldier.[3] He came to Constantinople, where he became a student of Michael Psellus in classical Greek philosophy. He succeeded Psellus in his position as head of the philosophical school. Subsequently, some of his tenets were found heretic in 1076-77 by Patriarch Cosmas I of Constantinople, and in 1082[4] he was personally condemned, having come into conflict with Emperor Alexios I Komnenos.
