Philostratus adds his own bit of personal testimony to the existence of demons, although it cannot be said to be very convincing. After telling the satyr story he warns his readers not to be incredulous as to the existence of satyrs or to doubt that they make love. For they should not mistrust what is supported by experience and by Philostratus’s own word. For he knew in Lemnos a youth of his own age whose mother was said to be visited by a satyr, and such he probably was, since he wore a fawn skin tied around his neck by the two front paws.[1235] [Sidenote: The ghost of Achilles.] Apollonius had an interview with the ghost of Achilles which strongly suggests necromancy. He sent his companions on board ship and passed the night alone at the hero’s tomb. Nor did he allude to what had happened until questioned by the curious Damis. He then averred that his method of invoking the dead had not been that of Odysseus, but that he had prayed to Achilles much as the Indians do to their heroes. A slight earthquake then occurred and Achilles appeared. At first he was five cubits tall but gradually increased to some twelve cubits in height. At cock-crow he vanished in a flash of summer lightning.[1236] [Sidenote: Healing the sick and raising the dead.] Apollonius, as well as the Brahmans, wrought some cures. One was of a boy who had been bitten by a mad dog and consequently “behaved exactly like a dog, for he barked and howled and went on all fours.”[1237] Apollonius first found and quieted the dog, and then made it lick the wound, a homeopathic treatment which cured the boy. It now only remained to cure the dog, too, and this the philosopher effected by praying to the river which was near by and then making the dog swim across it. “For,” concludes Philostratus, “a drink of water will cure a mad dog if he only can be induced to take it.” The modern reader will suspect that the dog was not mad to begin with and that Apollonius cleverly cured the boy’s complaint by the same force that had induced it—suggestion. Apollonius once revived a maiden who was being borne to the grave by touching her and saying something to her, but Philostratus honestly admits that he is not sure whether he restored her to life or detected signs of life in the body which had escaped the notice of everyone else.[1238] [Sidenote: Other marvels.]
