Ammonius

Ammonius, nicknamed Saccas because he was originally a porter at Alexandria, took to the study of philosophy, established an academy, and became the founder of the Neo-Platonic school in which the systems of Plato and Aristotle meet in combination with some elements of Christian theology. Origen, Longinus, and Plotinus were among his hearers. It is said that he was a Christian by birth, but it is a matter of dispute whether he professed the faith himself. He died in 243 A.D. at an advanced age.
