1. Ammonius Saccas

Ammonius Saccas, that is, the sack-bearer, is named as one of the first or most celebrated teachers of this school; he died A.D. 243. But we have none of his writings, nor have any traditions regarding his philosophy come down to us. Among his very numerous disciples Ammonius had many men celebrated in other branches of science, for example, Longinus and Origen; it is, however, uncertain if this were the Christian Father of that name. But his most renowned disciple in philosophy is Plotinus, through whose writings as they are preserved to us we derive our chief knowledge of the Neo-Platonic philosophy. The systematized fabric of this philosophy is, indeed, ascribed to him by those who came after, and this philosophy is known specially as his philosophy.
