'''Ammonius Hermiae''' ([[5th century]] AD) was a [[Byzantine Empire|Greek]] [[philosopher]], and the son of [[Hermias (philosopher)|Hermias]], a fellow-pupil of [[Proclus]], and the [[neoplatonism|Neoplatonic]] philosopher [[Aedesia]]. He taught at [[Alexandria]], and had among his scholars [[Asclepius of Tralles]], [[John Philoponus]], [[Damascius]] and [[Simplicius of Cilicia|Simplicius]].

Of his reputedly numerous writings, his commentaries on [[Plato]] and [[Ptolemy]] are lost, but we have:
#A commentary on the ''Isagoge'' of [[Porphyry (philosopher)|Porphyry]] (Venice, 1500 fol.);
#A commentary on the ''Categories'' (Venice, 1503 fol.), the authenticity of which is doubted by [[C. A. Brandis]];
#A commentary on the ''De Interpretatione'' (Venice, 1503 fol.). They are printed in Brandis's [[scholia]] to Aristotle, forming the fourth volume of the [[Berlin]] Aristotle; they are also edited (1891-1899) in A. Busse's ''Commentaria in Aristot. Graeca''. The special section on fate was published separately by [[J. C. Orelli]], ''Alex. Aphrod., Ammonii, et aliorum de Fato quae supersunt'' (Zürich, 1824).
#Other commentaries on the Topics and the first six books of the [[Metaphysics]] of [[Aristotle]] still exist in manuscript.

A life of Aristotle, ascribed to Ammonius, but with more accuracy to [[John Philoponus]], is often prefixed to editions of Aristotle. It has been printed separately, with Latin translation and scholia, at [[Leiden]], 1621, at [[Helmstedt]], 1666, and at [[Paris]], 1850.

Of the value of the logical writings of Ammonius there are various opinions. K. Prantl speaks of them with contempt.

For a list of his works see [[Johann Albert Fabricius|J. A. Fabricius]], ''Bibliotheca Graeca,'' v. 704-707: [[C. A. Brandis]], ''Uber d. Reihenf. d. Bucher d. Aristot. Org.,'' 283 f.; [[K. Prantl]], ''Gesch. d. Logik,'' i. 642.
