Theodoret says that Theophilus, bishop of Alexandria, exhibited to the inhabitants of that city the hollow statues into which the priests entered, from secret passages, to deliver the oracles. When, by Constantine's order, the temple of Æsculapius at Ægea, in Cilicia, was pulled down, there was driven out of it, says Eusebius in his life of that emperor, not a god, nor a demon, but the human impostor who had so long duped the credulity of nations. To this he adds the general observation that, in the statues of the gods that were thrown down, not the slightest appearance was found of gods, or demons, or even any wretched and gloomy spectres, but only hay, straw, or the bones of the dead. The greatest difficulty respecting oracles is surmounted, when it is ascertained and admitted, that demons had no concern with them. There is no longer any reason why they should cease precisely at the coming of Jesus Christ. And moreover, there are many proofs that oracles continued more than four hundred years after Jesus Christ, and that they were not totally silenced but by the total destruction of paganism. Suetonius, in the life of Nero, says the oracle of Delphi warned that emperor to be aware of seventy-three years, and that Nero concluded he was to die at that age, never thinking upon old Galba, who, at the age of seventy-three, deprived him of the empire. Philostratus, in his life of Apollonius of Tyana, who saw Domitian, informs us that Apollonius visited all the oracles of Greece, and that of Dodona, and that of Delphos; and that of Amphiaraus. Plutarch, who lived under Trajan, tells us that the oracles of Delphos still subsisted, although there was then only one priestess, instead of two or three. Under Adrian, Dion Chrysostom relates that he consulted the oracle of Delphos; he obtained from it an answer which appeared to him not a little perplexed, and which in fact was so. Under the Antonines, Lucian asserts that a priest of Tyana went to inquire of the false prophet Alexander, whether the oracles which were then delivered at Dindymus, Claros, and Delphos, were really answers of Apollo, or impostures? Alexander had some fellow-feeling for these oracles, which were of a similar description to his own, and replied to the priest, that that was not permitted to be known; but when the same wise inquirer asked what he should be after his death, he was boldly answered, "You will be a camel, then a horse, afterwards a philosopher, and at length a prophet as great as Alexander." After the Antonines, three emperors contended for the empire. The oracle of Delphos was consulted, says Spartian, to ascertain which of the three the republic might expect as its head. The oracle answered in a single verse to the following purport: The black is better; the African is good; the white is the worst. By the black was understood Pescennius Niger; by the African, Severus Septimus, who was from Africa; and by the white, Claudius Albinus.
