Apocalypse of Pseudo-Methodius

Written in Syriac in the late seventh century, the Apocalypse of Pseudo-Methodius shaped and influenced Christian eschatological thinking in the Middle Ages. Pseudepigraphically attributed to Methodius of Olympus, a fourth century Church Father, the work attempts to make sense of the Islamic conquest of the Near East.
