Ammonius, son of Hermeas

 The Greek philosopher Ammonius, ‘son of Hermeas’ was an Alexandrian Neoplatonist. Educated by Proclus in Athens, he succeeded his father as head of the school in Alexandria, where he cultivated the tradition of learned commentary on Aristotle. Simplicius, Philoponus, Asclepius, Damascius and Olympiodorus ranked among his pupils. Ammonius’ calibre is hard to assess: important works like commentaries on Aristotle’s On the Heavens and Meteorology and on Plato’s Gorgias, as well as monographs on logic and theology, are lost. Moreover, with the exception of the commentary on Aristotle’s De interpretatione, Ammonius left the task of writing out his lectures in full to his students.
