TEOGNOSTO of ALESSANDRIA. — Writer of the catechetical school of Alessandria, in the second half of the 3rd century, probably earlier than Pierio; according to Filippo di Side, however, he would have succeeded him (H. Dodwellus, Dissertationes in Irenaeum, Oxford 1689, p. 488).
He wrote a kind of dogmatic treatise under the title Hypotyposeis in 7 books, perhaps following the example of Origene in his De principis. It was, as appears from Fozio (Bibliot., cod. 106), who still had the complete work in his hands, a schoolbook that did not claim to be original in relation to the ideas of the master Origene. For this fidelity to Origene he was censured by Fozio. The judgment of St. Atanasio concerning T. was very favorable, as Stefano Gobaro had already observed (Fozio, Bibl., cod. 232). In addition to Fozio’s account, there are some fragments of T. (Atanasio, Ep. 4 ad Serap., chap. 11; Ep. de decr. Nicaen. Synod., chap. 25; Gregorio Nisseno, Contra Eunom., III, II, 121; ed. W. Iseger, vol. II, p. 86, 24 ff.) and a fragment in cod. Venet. Marcian., 502, f. 254; V. F. Diekamp, Theolog. Quartalschrift, Friburgo 1902, p. 483 ff.).
