d. c.282. Alexandrian priest and theologizer about whom little is known save through quotations in the writings of Photius, Athanasius, and Gregory of Nyssa. He authored a work titled Hypotyposes (in seven books), parts of which were hardly orthodox. In it he spoke of angels and devils having bodies, of Jesus Christ as a creature, and of the Holy Spirit in terms no more orthodox than Origen,* whose views he followed. As head of the Catechetical School he wielded some influence. Despite Theognostus's Origenistic tendencies and language, Athanasius* appealed to his writings in his struggle against Arianism.*
