 Hadot (2015, 23–25) thinks that Zacharias’ account proves that Horapollon’s school was a private institution when Ammonius taught there and that it is highly unlikely that a pagan philosopher could have received a municipal salary in Alexandria in Ammonius’ day, due to Christian hostility. She argues Ammonius and his colleagues will have relied on students’ fees for their income and therefore been more vulnerable than their Athenian colleagues, who lived communally, supported by the wealth of the Academy, which stemmed from bequests of the pious and learned (Life of Isidore 102). Support for this may come from Olympiodorus, who says (in Gorg. 43.2, 224.20–24; 43.4, 225.19–21; 43.6, 226.24–26) that philosophers will receive the merited thanks of their students for their help and must therefore not ask them for fees (misthous); but this is a hoary philosophical cliché (cf. Xenophon, Mem. 1.2.6–8). In his article on the complex of lecture rooms excavated in Alexandria, Sorabji (2014, 36–37) points to the size of the establishment and its rebuilding and expansion after the earthquake of 535 as indications of generous municipal support. It may well be that Christian Alexandria continued to support the teaching of pagan philosophers because they had an audience of students. There were still pagan students and those leaning toward paganism in the city. But Christians too will have been drawn to the high reputation of pagan Greek literature and philosophy. Christian students will also have sought the kind of dialectical skills taught by pagan philosophers and rhetoricians, along with their advanced logical and metaphysical teachings, the better to argue against them and the better to understand the philosophical basis of their own Christian faith (cf. Wildberg 2005, 234–236). After all, Zacharias stayed in Alexandria a year after Severus left to study law at Berytus because he needed further study of the rhetoricians and philosophers, so as to fight the pagans, who were so proud of them, with their own weapons (Life of Severus 46; cf. Champion 2014, 31–32).
