TEOFILATTO, archbishop of Bulgaria. Ecclesiastical writer of the 11th century. Born in Euboea around 1038, he studied in Constantinople at the school of Michael Psellos. He was deacon of Hagia Sophia when Michael VII Doukas (1071–78) entrusted him with the education of his son Constantine. Appointed archbishop of Bulgaria around 1078 (or 1092?), he had his see in Ohrid, where he nonetheless resided very unwillingly. He died presumably around 1108.
Notable among his works are his exegetical writings and his letters. He commented on the prophets Hosea, Habakkuk, Jonah, Nahum, Micah, the Psalms, and the entire New Testament except the Apocalypse. His letters, numbering 130, addressed largely to high-ranking figures in Constantinople, to his suffragan bishops, etc., are a valuable source of information on the cultural, social, and political situation of the time; unfortunately, the edition available is highly defective.
In addition, works attributed to T. include some homilies, a discourse in praise of Alexios I Komnenos, a treatise on the errors of the Latins, a Life of St Clement of Bulgaria, and a funeral oration addressed to Prince Constantine, his former pupil. The 25 homilies published by Sophronios Eustratiades in Trieste in 1903 and attributed to T. are not his, but belong to John IX Agapetos.
