Ammonius Saccas

Ammonius Saccas (/əˈmoʊniəs/; Ancient Greek: Ἀμμώνιος Σακκᾶς; 175 AD – 243 AD) was a Hellenistic Platonist self-taught philosopher from Alexandria, generally regarded as the precursor of Neoplatonism or one of its founders. He is mainly known as the teacher of Plotinus, whom he taught from 232 to 243. He was undoubtedly the most significant influence on Plotinus in his development of Neoplatonism, although little is known about his own philosophical views. Later Christian writers stated that Ammonius was a Christian, but it is now generally assumed that there was a different Ammonius of Alexandria who wrote biblical texts.
