c.174-c.242. Philosopher and teacher. Thought originally to have been a porter, he taught rhetoric and an eclectic and esoteric form of Platonism at Alexandria. His pupils included Origen, Plotinus the famous Neoplatonist, and a pagan Origen. The pagan biographer Porphyry claimed that learning made Ammonius reject his Christian upbringing for traditional paganism and that he left no writings. Eusebius is regarded as mistaken in his counterclaim that Ammonius was consistently a Christian philosopher and left such writings as On the Agreement of Moses and Jesus. His theories on Providence, the soul, and the cosmos echo the Christian Origen.
