- Ammonius Hermiae
Ammonius Hermiae (c. 440-c. 520) was a Greek
philosopher, and the son of the Neoplatonistphilosophers Hermias and Aedesia. He was a pupil of Proclusin Athens, and taught at Alexandriafor most of his life, writing commentaries on Plato, Aristotle, and other philosophers.
Ammonius father, Hermias, died when he was a child, and his mother, Aedesia, raised him and his brother, Heliodorus, in
Alexandria. When they reached adulthood, Aedesia accompanied her sons to Athenswhere they studied under Proclus. Eventually, they returned to Alexandria, where Ammonius, as head of the Neoplatonist school in Alexandria, lectured on Platoand Aristotlefor 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 Christianauthorities so that he could continue his lectures. [Damascius, "Philosophos Historia", 118B, Athanassiadi] 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 was still teaching in 515, since Olympiodorus heard him lecture on Plato's "Gorgias" in that year. [Olympiodorus, "in Gorgias", 199, 8-10] He also taught Asclepius of Tralles, John Philoponus, Damasciusand Simplicius.
Of his reputedly numerous writings, only his commentary on Aristotle's "De Interpretatione" survives intact. A commentary on Porphyry's "Isagogue" may also be his, but it is somewhat corrupt and contains later interpolations.
In addition, there are some notes of Ammonius' lectures written by various students which also survive:
*On Aristotle's "Categories" (anonymous writer)
*On Aristotle's "Prior Analytics I" (anonymous writer)
*On Aristotle's "Metaphysics 1-7" (written by Asclepius)
Nicomachus' "Introduction to Arithmetic" (written by Asclepius)
*On Aristotle's "Prior Analytics" (written by John Philoponus)
*On Aristotle's "Posterior Analytics" (written by John Philoponus)
*On Aristotle's "On Generation and Corruption" (written by John Philoponus)

He was also an accomplished
astronomer; he lectured on Ptolemyand is known to have written a treatise on the astrolabe.
