TEOFILATTO, archbishop of BULGARIA. — Ecclesiastical writer of the 11th century. Born in Euboea around 1038, he studied in Constantinople at the school of Michele Psello. He was deacon of S. Sofia when Michele VII Ducas (1071–78) entrusted him with the education of his son Costantino. Appointed archbishop of Bulgaria around 1078 (or 1092?), he had his seat at Ochrida, where, however, he resided very unwillingly. He presumably died around 1108.
Noteworthy among his works are his exegetical writings and letters. He commented on the prophets Hosea, Habakkuk, Jonah, Nahum, Micah, the Psalms, and the whole New Testament, except the Apocalypse. His letters, numbering 130, addressed for the most part to high-ranking figures in Constantinople, to his suffragan bishops, etc., are a valuable source of information concerning the cultural, social, and political situation of the time; unfortunately, the edition available is very defective.
There also survive some homilies by T., an oration in praise of Alessio I Comneno, a short treatise on the errors of the Latins, a Vita of s. Clemente di Bulgaria, and a paraenetic work addressed to Prince Costantino, his pupil. The 25 homilies published by Sofronio Eustratiades at Trieste in 1903 and attributed by him to T. are not his, but those of Giov. IX Agapeto.
