Aristotle and his followers affirm that all this proceeds from an exhalation within the earth, and when this fails or removes to another place, or revives and recovers itself again, the phenomena proceeding from them do so too. The same must we say of the prophetical exhalations which spring from the earth, that their virtue also is not immortal, but may wax old and decay; for it is not unlikely that great floods of rain and showers do extinguish them, and that the claps of thunder do dissipate them; or else (which I look upon to be the principal cause) they are sunk lower into the earth or utterly destroyed by the shock of earthquakes and the confusion that attends them, as here in this place there still remain the tragical monuments of that great earthquake that overthrew the city. And in the town of Orchomenus, they say, when the pestilence carried away such multitudes of people, the oracle of Tiresias of a sudden ceased, and remains mute to this day. And whether the like has not happened to the oracles in Cilicia, as we have heard it hath, no man can better inform us than you, Demetrius.
