On the strength of his Aristotelian "Paraphrases" Themistius may be called a scholar, though hardly a philosopher as he himself claimed. Technically he was a Sophist: that is to say he gave public lectures (??????????), wrote exercises after the Sophistic pattern and went on embassies, which were entrusted to him solely on account of his persuasive charm. But he insisted that he was no Sophist, because he took no fees1 and styled himself a practical philosopher.2 He was indifferent to the Neo-Platonic philosophy,3 and, since Constantius made him a Senator, he cannot have betrayed any zeal for the Pagan religion. From Julian's Pagan restoration he seems to have held aloof, and, though Julian had been his pupil, probably at Nicomedia, he did not appoint him to any office. Under the Christian Emperor Theodosius he held a prefecture. There is no evidence for a positive coolness, such as Zeller4 assumes, between Themistius and Julian, and we know too little of their relations to assert with some critics that the respectful tone of this letter is ironical.5It was probably written after Julian had become Emperor, though there is nothing in it that would not suit an earlier date; it is sometimes assigned to 355 when Julian was still Caesar. The quotations from Aristotle are appropriately addressed to Themistius as an Aristotelian commentator.
