We arrived at last at a wide cavern with an arched domelike roof. An aperture in the midst let in the light of heaven; but this was overgrown with brambles and underwood, which acted as a veil, obscuring the day, and giving a solemn religious hue to the apartment. It was spacious, and nearly circular, with a raised seat of stone, about the size of a Grecian couch, at one end. The only sign that life had been here, was the perfect snow-white skeleton of a goat, which had probably not perceived the opening as it grazed on the hill above, and had fallen headlong. Ages perhaps had elapsed since this catastrophe; and the ruin it had made above, had been repaired by the growth of vegetation during many hundred summers. The rest of the furniture of the cavern consisted of piles of leaves, fragments of bark, and a white filmy substance, resembling the inner part of the green hood which shelters the grain of the unripe Indian corn. We were fatigued by our struggles to attain this point, and seated ourselves on the rocky couch, while the sounds of tinkling sheep-bells, and shout of shepherd-boy, reached us from above. At length my friend, who had taken up some of the leaves strewed about, exclaimed, "This IS the Sibyl's cave; these are Sibylline leaves." On examination, we found that all the leaves, bark, and other substances, were traced with written characters. What appeared to us more astonishing, was that these writings were expressed in various languages: some unknown to my companion, ancient Chaldee, and Egyptian hieroglyphics, old as the Pyramids. Stranger still, some were in modern dialects, English and Italian. We could make out little by the dim light, but they seemed to containprophecies, detailed relations of events but lately passed; names, now well known, but of modern date; and often exclamations of exultation or woe, of victory or defeat, were traced on their thin scant pages. . . .
