Lucan, and others, Plutarch accounts for the cause of it, either that the benefits of the gods are not eternal, as themselves are; or that the genii who presided over oracles, are subject to death; or that the exhalations of the earth had been exhausted. It appears that the last reason had been alleged in the time of Cicero, who ridicules it in his second book of Divination, as if the spirit of prophecy, supposed to be excited by subterranean effluvia, had evaporated by length of time, as wine or pickle by being kept is lost. Suidas, Nicephorus, and Cedrenus relate, that Augustus having consulted the oracle of Delphos, could obtain no other answer but this: 'the Hebrew child whom all the gods obey, drives me hence, and sends me back to hell: get out of this temple without speaking one word.' Suidas adds, that Augustus dedicated an altar in the Capitol, with the following inscription: "_To the eldest Son of God_." Notwithstanding these testimonies, the answer of the oracle of Delphos to Augustus seems very suspicious. Cedrenus cites Eusebius for this oracle, which is not now found in his works; and Augustus' peregrination into Greece was eighteen years before the birth of Christ. Suidas and Cedrenus give an account also of an ancient oracle delivered to Thules, a king of Egypt, which they say is well authenticated. This king having consulted the oracle of Seraphis, to know if there ever was, or would be, one so great as himself, received this answer:--"First, God, next the word, and the spirit with them. They are equally eternal, and make but one whose power will never end. But thou, mortal, go hence, and think that the end of man's life is uncertain." Van Dale, in his Treatise of oracles, does not believe that they ceased at the coming of Christ. He relates several examples of oracles consulted till the death of Theodosius the Great. He quotes the laws of the Emperors Theodosius, Gratian, and Valentinian, against those who consulted oracles, as a certain proof that the superstition of oracles still existed in the time of those emperors. HAD DEMONS ANY SHARE IN THE ORACLES?
