good deal of sermonizing. [Sidenote: Philostratus’s sources.] Philostratus[1124] composed the _Life of Apollonius_ about 217 A. D. at the request of the learned wife of the emperor Septimius Severus, to whose literary circle he belonged. The empress had come into possession of some hitherto unknown memoirs of Apollonius by a certain Damis of Nineveh, who had been his disciple and had accompanied him upon many of his travels. Some member of Damis’s family had brought these documents to the empress’s attention. Some scholars incline to the view that she was deceived by an impostor, but it hardly seems that there would be sufficient profit in the venture to induce anyone to take the pains to forge such memoirs. Also I can see no reason why a contemporary of Apollonius should not have said and believed everything which Philostratus represents Damis as saying; on the contrary it seems to me just what would be said by a naïf, gullible, and devoted disciple, who was inclined to exaggerate the abilities and achievements of his master and to take literally everything that Apollonius uttered ironically or figuratively. Other accounts of Apollonius were already in existence by a Maximus of Aegae, where Apollonius had spent part of his life, and by Moeragenes, but the memoirs of Damis seem to have offered much new material. Philostratus accordingly wrote a new life based largely upon Damis, but also making use of the will and epistles of Apollonius, many of which the emperor Hadrian had earlier collected, and of the traditions still current in the cities and temples which Apollonius had frequented and which Philostratus now took the trouble to visit. It has sometimes been suggested, chiefly by Christian writers intent upon discrediting the career of Apollonius, that Philostratus invented Damis and his memoirs. But Philostratus seems straightforward in describing the pains he has been to in preparing the _Life_, and certainly is more explicit and systematic in stating his sources than other ancient biographers like Plutarch and Suetonius are. He appears to follow his sources rather closely and not to invent new incidents, although he may, like Thucydides and other ancient historians, have taken liberties with the speeches and arguments put into his characters’ mouths. And through the work, despite his belief in demons and marvels, he now and then gives evidence of a moderate and sceptical mind, at least for his times. [Sidenote: Time and space covered.]
