Fortunatianus, an African by birth, bishop of Aquilia during the reign of Constantius, composed brief Commentaries on the gospels arranged by chapters, written in a rustic style, and is held in detestation because, when Liberius bishop of Rome was driven into exile for the faith, he was induced by the urgency of Fortunatianus to subscribe to heresy.
