Theognostus of Alexandria

Theognostus (; c. 210 – c. 270) was a late 3rd century Alexandrian theologian. He is known from quotes by Athanasius and Photios I of Constantinople. Although a disciple of Origen of Alexandria no reference of him can be found by Eusebius or Jerome. The main textual point of reference is derived from Athanasius.

Works He wrote a seven-volume work called Hypotyposes, extant at the time of Photius' quotation. The fragments of Theognostus are collected in Martin Joseph Routh's Reliquiae Sacrae 3:407–422. Translations into English can be found in the Ante-Nicene Fathers (available at WikiSource). Most of the 2nd book was later published in 1902 by Franz Diekamp.

Exegetical writings Hypotypōseis: The seven books known in Greek as the "Outlines" a title given by Photios I of Constantinople is considered to be Theognostus' principal work. Themes include: Book I Creation Book II The Divinity of Christ Book III The Holy Spirit Book IV Angels and Devils Books VI & V The Divinity of God Book VII A return to creation.
