Apollonius lived in the first century of our era and died during the reign of Nerva well advanced in years. It is therefore of a period over a century before his own that Philostratus writes. He is said to commit a number of errors in history and geography,[1125] but we must remember that mistakes in geography were a failing of the best ancient historians such as Polybius, and the general picture drawn of the emperors and politics of Apollonius’s time is not far wrong. It is true that Philostratus also makes use of tradition which has gradually formed since the death of Apollonius, and introduces explanations or comments of his own on various matters. It is, however, not the facts either of Apollonius’s career or of his times that concern us but the beliefs and superstitions which we find in Philostratus’s _Life_ of him. Whether these are of the first, second, or early third century is scarcely necessary or possible for us to distinguish. If Damis records them, Philostratus accepts them, and the probability is that they apply not only to all three centuries but to a long period before and after. The territory covered in the _Life_ is almost as extensive; it ranges all over the Roman Empire, alludes occasionally to the Celts and Scythians, and opens up Ethiopia and India[1126] to our gaze. Apollonius was a great traveler and there are many interesting and informing passages concerning ships, sailing, pilots, merchants and sea-trade.[1127] [Sidenote: Philostratus’s audience.] If we ask further, for what class of readers was the _Life_ intended, the answer is, for the intellectual and learned. Apollonius himself was distinctly a Hellene. Philostratus represents him as often quoting Homer and other bygone Greek authors, or mentioning names from early Greek history such as Lycurgus and Aristides. One of his aims was to restore the degenerate Greek cities of his own day to their ancient morality. Furthermore, Apollonius never cared for many disciples, and neither required them to observe all the rules of life which he himself followed, nor admitted them to all his interviews with other sages and his initiations into sacred mysteries. This aloofness of the sage is somewhat reflected in his biographer. The _Life_ is an attempt not to popularize the teachings of Apollonius but to justify him before the learned world.
