Hieromartyr Victorinus, Bishop of Poetovio (Pettau)

Hieromartyr Victorinus was born around 230; according to the testimony of Blessed Jerome of Stridon (the chief source of information about him), he knew Greek far better than Latin, suggesting an Eastern origin, with comparatively modest Latin literary training but deep theological knowledge. He was bishop of the city of Poetovio (modern Ptuj, Slovenia) in the Roman province of Upper Pannonia.

He is recognized as the first Latin interpreter of Holy Scripture and author of the earliest completely surviving commentary on the Apocalypse (Commentary on the Revelation of John), heavily influenced by Origen and Hieromartyr Hippolytus of Rome (allegorical method of interpretation); Blessed Jerome later revised and edited this work. He also wrote a treatise "On the Creation of the World" (De Fabrica Mundi). His exegesis influenced later Western theologians — St. Hilary, St. Ambrose, Rufinus, and Jerome himself. His theology shows certain archaic, binitarian tendencies (blending the images of the Son and Spirit), typical of pre-Nicene Latin theology.

He was martyred during the persecution of Emperor Diocletian, traditionally around 303 or 304.
