Ammonius Saccus

(fl. 200-50) Alexandrian Platonist, and teacher of Plotinus and Origen (not to be confused with an earlier Ammonius, who taught Plutarch). Little is known of Ammonius, who seems to have belonged to the Neo-Pythagorean underground, and stood at some remove from orthodox philosophy of his time. Attempts to reconstruct his teaching by finding common elements in Plotinus and Origen have not been successful.
