Theognostus
(Θεόγνωστος).
1. A Christian writer, a native of Alexandria, the author of a work entitled τοῦ μακαρίου Θεογνώστον Ἀλεξανδπέως καὶ ἐξηγητοῦ ὑποτυπώσεις. Photius, who speaks in very disrespectful terms of him, gives a brief account of the contents of the work. (Cod. 106.) It seems. from what he says, that Theognostus gnostus closely followed Origenes. The style is described by Photius as being of a very inferior Description. Athanasius. However, speaks in much higher terms of Theognostus. (Fabric. Bibl. Graec. vol. x. p. 709.)
2. A Byzantine grammarian, who lived at the beginning of the ninth century after Christ. He was the author of a work on prosody, which is still extant in manuscript, addressed to the emperor Leo, the Armenian. He also wrote a history of the reign of Michael II., surnamed the Stammerer, the successor of Leo. (Villoison, Anecd. Graec. vol. ii. p. 127; Fabric. Bibl. Graec. vol. vi. p. 350.) [C.P.M]
