* Ammonius of Athens ( 1st century AD ), philosopher and teacher of Plutarch

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.

He studied at Alexandria under Ammonius Saccas and Origen the Pagan, and taught for thirty years in Athens, one of his pupils being Porphyry.

Of the first two Longinus was a pupil for a long time, but Longinus did not embrace the Neoplatonism then being developed by Ammonius and Plotinus, rather he continued as a Platonist of the old type.

The French scholar Pierre Courcelle has argued that Boethius studied at Alexandria with the Neo-Platonist philosopher Ammonius Hermiae.

Albucasis follows Paulus almost word for word but then describes a different sort of knife one that is " sharp on two sides " ( Spinks and Lewis say it's difficult to reconcile the drawing of the knife to the procedure ) Albucasis also adds using forceps instead of the scoop and chisel of Ammonius to break up the stone.

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.

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

According to Porphyry, the parents of Ammonius were Christians, but upon learning Greek philosophy, Ammonius rejected his parents ' religion for paganism.

However, the Christian population of Alexandria knew that Ammonius had been killed for his assault and not for his faith, and Cyril was obliged to remain silent about the events.

Upon hearing Ammonius lecture, he declared to his friend, " this was the man I was looking for ," and began to study intently under his new instructor.

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.

In addition, we have to thank him for such copious quotations from the Greek commentaries from the time of Andronicus of Rhodes down to Ammonius and Damascius, that, for the Categories and the Physics, the outlines of a history of the interpretation and criticism of those books may be composed.

Ammonius, who practiced lithotomy in Alexandria circa 200 BC, acquired the surname Lithotomus from the instrument he developed for fragmenting stones too large to pass through a small perineal incision.

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.

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.

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

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.

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

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.

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.

Socrates ' teachers, noted in his prefaces, were the grammarians Helladius and Ammonius, who came to Constantinople from Alexandria, where they had been pagan priests.

In his view not only Plotinus, but also Syrianus, Proclus, and Ammonius, are great philosophers, who have penetrated into the depths of the wisdom of Plato.

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.

He was a pupil and sometime amanuensis to the Neoplatonic philosopher Ammonius Hermiae, who had studied at Athens under Proclus.

Not much is known about the life of Ammonius Saccas.

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.

It is quite possible that Ammonius Saccas taught both Origens.

Ammonius Grammaticus is the supposed author of a treatise titled Peri homoíōn kai diaphórōn léxeōn ( περὶ ὁμοίων καὶ διαφόρων λέξεων, On the Differences of Synonymous Expressions ), of whom nothing is known.

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.

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.

The bishop also seized the body of Ammonius and put it in a church, conferring upon him the title of Thaumasius and putting his name in the list of the martyrs.

In addition, there are some notes of Ammonius ' lectures written by various students which also survive:

* On Synonyms, of which there is extant an epitome by Ammonius Grammaticus.

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.

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.

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