* Ammonius Saccas ( 3rd century AD )

Ammonius Saccas ( 3rd century AD ) () was a Greek philosopher from Alexandria who was often referred to as one of the founders of Neoplatonism.

Not much is known about the life of Ammonius Saccas.

The most famous pupil of Ammonius Saccas was Plotinus who studied under Ammonius for eleven years.

One way to explain much of the confusion concerning Ammonius is to assume that there were two people called Ammonius: Ammonius Saccas who taught Plotinus, and an Ammonius the Christian who wrote biblical texts.

It is quite possible that Ammonius Saccas taught both Origens.

Ammonius asks Plutarch what he, being a Boeotian, has to say for Cadmus, the Phoenician who reputedly settled in Thebes and introduced the alphabet to Greece, placing alpha first because it is the Phoenician name for ox — which, unlike Hesiod, the Phoenicians considered not the second or third, but the first of all necessities.

Ammonius Hermiae (; c. 440-c. 520 ) was a Greek philosopher, and the son of the Neoplatonist philosophers Hermias and Aedesia.

Ammonius ' father, Hermias, died when he was a child, and his mother, Aedesia, raised him and his brother, Heliodorus, in Alexandria.

Eventually, they returned to Alexandria, where Ammonius, as head of the Neoplatonist school in Alexandria, lectured on Plato and Aristotle for the rest of his life.

According to Damascius, during the persecution of the pagans at Alexandria in the late 480's, Ammonius made concessions to the Christian authorities so that he could continue his lectures.

Damascius, who scolds Ammonius for the agreement that he made, does not say what the concessions were, but it may have involved limitations on the doctrines he could teach or promote.

In De Interpretatione, Ammonius contends that divine foreknowledge makes void the contingent.

Ammonius cites Iamblichus who said knowledge is intermediate between the knower and the known, since it is the activity of the knower concerning the known.
