The divining faculty of Apollonius enabled him to detect the presence and influence of demons, phantoms, and goblins, whose ways he understood as well as the language of the birds. At Ephesus he detected the true cause of the plague in a ragged old beggar whom he ordered the people to stone to death.[1224] At this command the blinking eyes of the aged mendicant suddenly shot forth malevolent and fiery gleams and revealed his demon character. Afterwards, when the people removed the stones, they found underneath, pounded to a pulp, an enormous hound still vomiting foam as mad dogs do. Later, when accused of magic before Domitian, Apollonius requested that the emperor question him in private about the causes of this pestilence at Ephesus, which he said were too deep to be discussed publicly.[1225] And earlier in the reign of Nero, when asked by Tigellinus how he got the better of demons and phantasms, he evaded the question by a saucy retort.[1226] On one occasion, however, we are told that he got rid of a ghostly apparition by heaping abuse upon it;[1227] and a satyr, who remained invisible but created annoyance by running amuck through the camp, he disposed of by the expedient of filling a trough with wine and letting the spirit get drunk on it. When the wine had all disappeared, Apollonius led his companions to the cave of the nymphs where the satyr was now visible in a drunken sleep.[1228] He also reformed the character of a licentious youth by expelling a demon from him,[1229] and at Corinth exposed a lamia who, under the disguise of a dainty and wealthy lady, was fattening up a beautiful youth named Menippus with the intention of eventually devouring his blood.[1230] On his return by sea from India Apollonius passed a sacred island where lived a sea nymph or female demon who was as destructive to mariners as Scylla or the Sirens were of old. [Sidenote: Not all demons are evil] But the word “demon” is not always employed by Philostratus in the sense of an evil spirit. The annunciation of the birth of Apollonius was made to his mother by Proteus in the form of an Egyptian demon.[1231] Damis looked upon Apollonius himself as a demon and worshiped him as such, when he heard him say that he comprehended not only all human languages but also those things concerning which men maintain silence.[1232] In a letter to Euphrates[1233] Apollonius affirms that the all-wise Pythagoras should be classed among demons. But when Domitian, on first meeting Apollonius said that he looked like a demon, the sage replied that the emperor was confusing demons and human beings.[1234] [Sidenote: Philostratus’s faith in demons.]
