 Ammonius was chiefly influential as the founder of the school of Aristotle-interpretation in Alexandria. Nearly all the principal commentators who came after him were his pupils or his pupils’ pupils. He gave a model for the method of exegesis of Aristotle and Plato and his lecturing style made an impression on students. His commentary on De Interpretatione was particularly important and served as a source for Stephanus and other commentators. In its translation by William of Moerbeke, this work was influential on Aquinas and thus on medieval and later Aristotelian philosopy and semantics (cf., e.g., Fortier 2012). Ammonius’ new set of introductions to philosophy and the study of Aristotle, once adopted and adapted by his Alexandrian students—Olympiodorus, Elias, David, Pseudo-Elias, and Philoponus, were also transferred to other languages and cultures. Importantly, a number of his and his students’ works were studied and translated into Persian, Arabic and Syriac, where Ammonius’ influence was carried forward (cf. the brief overview of the diffusion of Ammonius’ new curriculum and its introductions in Sorabji 2016c, 49–53, also with further literature on the translations of works from Ammonius’ school). As an example of this diffusion, take the larger commentary on the Categories by Sergius of Reshaina (d. 536), who studied with Ammonius at Alexandria and later became a physician in his home city (see Hugonnard-Roche 2004 and Watt 2010, both with further literature).
