Authors/Ammonius H

From SEP article:

Ammonius (ca. 435/445–517/526) held the chair of philosophy at Alexandria that had earlier been held by his father Hermeias. Known primarily for his commentaries on Aristotle, which were said to be of greater benefit than anyone else's, he was also distinguished in geometry and astronomy. Himself a pupil of Proclus at Athens, at Alexandria Ammonius taught most of the important Platonists of the late 5th and early 6th centuries: Philoponus, Asclepius, Simplicius, and Olympiodorus. Damascius, who went on to head the school at Athens, heard Ammonius lecture, but attached himself rather to the mentorship of Isidore, who briefly succeeded Proclus' successor Marinus in the Athenian chair. While almost all of Ammonius' Aristotle commentaries were published by students from his lectures, the large commentary on De Interpretatione was written up by Ammonius himself for publication. These commentaries are largely dependent on the lectures of Proclus and thus indebted to Proclus' style of Iamblichean Neoplatonism. Ammonius is known for several contributions, especially for the introduction of an Alexandrian tradition of commentary on Aristotle, but also for the first preserved version of the set of questions to be answered preliminary to the study of Aristotle, the thesis that for Aristotle God is the efficient as well as final cause of the world, and the treatment of the sea battle of De Interpretatione 9 as one of three determinist arguments, along with the ‘Reaper’ and the argument from divine foreknowledge.
