Until the 19th century Ammonius was credited with devising the early medieval divisions of the text of the Four Gospels, still usually known as the Ammonian Sections. These are now usually ascribed to Eusebius of Caesarea instead. Eusebius of Caesarea (Church History, vi. 19), who is followed by Jerome, asserts that Ammonius was born a Christian, remained faithful to Christianity throughout his life, and produced two works, The Harmony of Moses and Jesus and a Diatessaron, or The Harmony of the Four Gospels. There is an extant Latin translation by the sixth century bishop Victor of Capua of an anonymous Diatessaron, it is generally ascribed it to Tatian, but it could have been written by Ammonius.
