Stephanus of Alexandria original: Stephanus Alexandrinus, about whom H. Usener recently wrote with great care (Commentary on Stephanus of Alexandria, Bonn 1880 The original date is written in Roman numerals as CIƆIƆCCCLXXX), came from Alexandria to Constantinople with the Emperor Heraclius; there he performed the duties of a universal teacher original Greek: οἰκουμενικοῦ διδασκάλου (oikoumenikou didaskalou), a prestigious title for a head of the imperial university. In addition to Aristotle's book On Interpretation original: Περὶ ἑρμηνείας (Peri hermeneias) (compare A. Müller, Greek Philosophy in Arabic Tradition, Halle 1873, p. 14; Usener p. 7¹), he interpreted the Categories (compare Usener p. 7 and his own commentary p. 21, 5) and the books On the Heavens original: de Caelo (Brandis's Scholia p. 467ᵇ36, Usener as cited above); likewise, he is called the commentator of the books On the Soul original: de Anima in the Vatican Greek Codex 241, dating to the 14th century, at folio 6. I transcribe that entire passage here:
