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.*
