  The teaching of philosophy did not cease with the death of Olympiodorus. He evidently had intelligent pupils who devoted themselves to philosophy in a professional way. Whether they were pagans or Christians is not entirely clear, but their commentaries were passed around under such names as David and Elias. We can tell that they were influenced by Olympiodorus, not only because they refer to him, but also because they adopt his pedagogical method of dividing their lectures into theôriai and lexeis. The same goes for Stephanus of Alexandria, who taught philosophy in Constantinople at the beginning of the 7th century.
