It is just beneath the tomb that the road to Pozzuoli enters the famous Grotto of Posilipo, a tunnel about half a mile long, in breadth from 25 to 30 feet, and varying from about 90 feet in height near the entrance, to little more than 20 feet at points of the interior. Petronius and Seneca mention its narrow gloomy passage with horror, in the reign of Nero, when it was so low that it could only be used for foot-passengers, who were obliged to stoop in passing through.
In the fifteenth century King Alphonso I. gave it height by lowering the floor, which was paved by Don Pedro di Toledo a hundred years later. In the Middle Ages the grotto was ascribed to the magic arts of Virgil. In recent years it has been the chief means of communication between Naples and Baiae, and is at all times filled with dust and noise, the flickering lights and resounding echoes giving it a most weird effect. However much one may abuse Neapolitans, we may consider in their favor, as Swinburne observes, "what a terror this dark grotto would be in London!"
TWO ASCENTS OF VESUVIUS[8]
BY JOHANN WOLGANG VON GOETHE
At the foot of the steep ascent, we were received by two guides, one old, the other young, but both active fellows. The first pulled me up the path, the other Tischbein[9]—pulled I say, for these guides are girded round the waist with a leathern belt, which the traveler takes hold of, and being drawn up by his guide, makes his way the easier with foot and staff. In this manner we reached the flat from which the cone rises; toward the north lay the ruins of the summit.
A glance westward over the country beneath us, removed, as well as a bath could, all feeling of exhaustion and fatigue, and we now went round the ever-smoking cone, as it threw out its stones and ashes. Wherever the space allowed of our viewing it at a sufficient distance, it appeared a grand and elevating spectacle. In the first place, a violent thundering toned forth from its deepest abyss, then stones of larger and smaller sizes were showered into the air by thousands, and enveloped by clouds of ashes. The greatest part fell again into the gorge; the rest of the fragments, receiving a lateral inclination, and falling on the outside of the crater, made a marvelous rumbling noise. First of all the larger masses plumped against the side, and rebounded with a dull heavy sound; then the smaller came rattling down; and last of all, drizzled a shower of ashes. All this took place at regular intervals, which by slowly counting, we were able to measure pretty accurately.
Between the summit, however, and the cone the space is narrow enough; moreover, several stones fell around us, and made the circuit anything but agreeable. Tischbein now felt more disgusted than ever with Vesuvius, as the monster, not content with being hateful, showed an inclination to become mischievous also.
As, however, the presence of danger generally exercises on man a kind of attraction, and calls forth a spirit of opposition in the human breast to defy it, I bethought myself that, in the interval of the eruptions, it would be possible to climb up the cone to the crater, and to get back before it broke out again. I held a council on this point with our guides under one of the overhanging rocks of the summit, where, encamped in safety, we refreshed ourselves with the provisions we had brought with us. The younger guide was willing to run the risk with me; we stuffed our hats full of linen and silk handkerchiefs, and, staff in hand, we prepared to start, I holding on to his girdle.
The little stones were yet rattling around us, and the ashes still drizzling, as the stalwart youth hurried forth with me across the hot glowing rubble. We soon stood on the brink of the vast chasm, the smoke of which, altho a gentle air was bearing it away from us, unfortunately veiled the interior of the crater, which smoked all round from a thousand crannies. At intervals, however, we caught sight through the smoke of the cracked walls of the rock. The view was neither instructive nor delightful; but for the very reason that one saw nothing, one lingered in the hope of catching a glimpse of something more; and so we forgot our slow counting. We were standing on a narrow ridge of the vast abyss; of a sudden the thunder pealed aloud; we ducked our heads involuntarily, as if that would have rescued us from the precipitated masses. The smaller stones soon rattled, and without considering that we had again an interval of cessation before us, and only too much rejoiced to have outstood the danger, we rushed down and reached the foot of the hill together with the drizzling ashes, which pretty thickly covered our heads and shoulders....
