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

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.

Not much is known about the life of Ammonius Saccas.

This conversion is contested by the Christian writers Jerome and Eusebius, who state that Ammonius remained a Christian throughout his lifetime:

However we are told by Longinus that Ammonius wrote nothing, and if Ammonius was the principal influence on Plotinus, then it is unlikely that Ammonius would have been a Christian.

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.

that the real author was Herennius Philo of Byblus, who was born during the reign of Nero and lived till the reign of Hadrian, and that the treatise in its present form is a revision prepared by a later Byzantine editor, whose name may have been Ammonius.

Plotinus is noted as the founder of Neoplatonism ( along with his teacher Ammonius Saccas ).

His teacher was Ammonius Saccas and he is of the Platonic tradition.

* Origen, disciple of Ammonius Saccas, founder of Neoplatonism, is exiled in Caesarea.

He had received his training partly in Alexandria, under Ammonius, partly in Athens, as a disciple of Damascius ; and it was probably in one of these two cities that he subsequently took up his abode ; for, with the exception of these cities and Constantinople, it would have been difficult to find a town which possessed the collections of books he needed, and he is unlikely to have gone to Constantinople.

This collection, which includes the Pœmandres and some addresses of Hermes to disciples Tat, Ammon and Asclepius, was said to have originated in the school of Ammonius Saccas and to have passed through the keeping of Michael Psellus: it is preserved in fourteenth century manuscripts.

His father's name is given as Ammonius.

Lithoclastic cystotomy is attributed to Ammonius Lithotomos ( stone-cutter ) of Alexandria, Egypt.

In the preface to his work On Ends, which is preserved in Porphyry's Life of Plotinus, Longinus himself relates that from his early age he made many journeys with his parents, that he visited many countries and became acquainted with all those who at the time enjoyed a great reputation as philosophers, among whom the most illustrious were Ammonius Saccas, Origen the Pagan, Plotinus, and Amelius.

Philoponus ’ early writings are based on lectures given by Ammonius, but gradually he established his own independent thinking in his commentaries and critiques of Aristotle ’ s On the Soul and Physics.

However, Papias's millennialism ( according to Anastasius of Sinai, along with Clement of Alexandria and Ammonius he understood the Six Days ( Hexaemeron ) and the account of Paradise as referring mystically to Christ and His Church ) was nearer in spirit to the actual Christianity of the sub-apostolic age, especially in western Anatolia ( e. g., Montanism ), than Eusebius realized.

Commentaries on the Almagest were written by Theon of Alexandria ( extant ), Pappus of Alexandria ( only fragments survive ), and Ammonius Hermiae ( lost ).

The text includes, in addition to the Gospels, the letter of Jerome to Pope Damasus ( known by its first two words Novum opus ), the prologue to Jerome's commentary on the Book of Matthew, the letter of Eusebius of Caesarea to Carpianus ( Ammonius quidam ) in which Eusebius explains the use of his Canon Tables, prologues to each of the Gospels, tables of capitula for each of the Gospels, tables for each of the Gospels indicating the festivals at which portions of that Gospel should be read, and the Eusebian Canon tables.

The friend, understanding the desire of his heart, sent him to Ammonius, whom he had not so far tried.

After Longinus had learnt all he could from Ammonius at Alexandria and the other philosophers whom he met in his travels, he returned to Athens.

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