The tripod, we are told, stood over a chasm in the rock, from which issued fumes of an inebriating quality. The Pythia became gradually penetrated through every limb with these fumes, till her bosom swelled, her features enlarged, her mouth foamed, her voice seemed supernatural, and she uttered words that could sometimes scarcely be called articulate. She could with difficulty contain herself, and seemed to be possessed, and wholly overpowered, with the God. After a prelude of many unintelligible sounds, uttered with fervour and a sort of frenzy, she became by degrees more distinct. She uttered incoherent sentences, with breaks and pauses, that were filled up with preternatural efforts and distorted gestures; while the priests stood by, carefully recording her words, and then reducing them into a sort of obscure signification. They finally digested them for the most part into a species of hexameter verse. We may suppose the supplicants during this ceremony placed at a proper distance, so as to observe these things imperfectly, while the less they understood, they were ordinarily the more impressed with religious awe, and prepared implicitly to receive what was communicated to them. Sometimes the priestess found herself in a frame, not entirely equal to her function, and refused for the present to proceed with the ceremony. The priests of the oracle doubtless conducted them in a certain degree like the gipsies and fortune-tellers of modern times, cunningly procuring to themselves intelligence in whatever way they could, and ingeniously worming out the secrets of their suitors, at the same time contriving that their drift should least of all be suspected. But their main resource probably was in the obscurity, almost amounting to unintelligibleness, of their responses. Their prophecies in most cases required the comment of the event to make them understood; and it not seldom happened, that the meaning in the sequel was found to be the diametrically opposite of that which the pious votaries had originally conceived. In the mean time the obscurity of the oracles was of inexpressible service to the cause of superstition. If the event turned out to be such as could in no way be twisted to come within the scope of the response, the pious suitor only concluded that the failure was owing to the grossness and carnality of his own apprehension, and not to any deficiency in the institution. Thus the oracle by no means lost credit, even when its meaning remained for ever in its original obscurity. But, when, by any fortunate chance, its predictions seemed to be verified, then the unerringness of the oracle was lauded from nation to nation; and the omniscience of the God was admitted with astonishment and adoration.
