the German Universities. He had stayed a day or two in the town longer than ordinary, to take the measures of several empty spaces that had been cut in the sides of a neighbouring mountain. Some of them were supported with pillars formed out of the rock, some were made in the fashion of galleries, and some not unlike amphitheatres. The gentleman had made to himself several ingenious hypotheses concerning the use of these subterraneous apartments, and from thence collected the vast magnificence and luxury of the ancient Chateaudunois. But upon communicating his thoughts upon this subject to one of the most learned of the place, he was not a little surprised to hear that these stupendous works of art were only so many quarries of free-stone, that had been wrought into different figures, according as the veins of it directed the workmen. About five miles from the grotto of Pausilypo lie the remains of Puteoli and Bajæ, in a soft air and a delicious situation. The country about them, by reason of its vast caverns and subterraneous fires, has been miserably torn in pieces by earthquakes, so that the whole face of it is quite changed from what it was formerly. The sea has overwhelmed a multitude of palaces, which may be seen at the bottom of the water in a calm day. The Lucrine lake is but a puddle in comparison of what it once was, its springs having been sunk in an earthquake, or stopped up by mountains that have fallen upon them. The lake of Avernus, formerly so famous for its streams of poison, is now plentifully stocked with fish and fowl. Mount Gaurus, from one of the fruitfullest parts in Italy, is become one of the most barren. Several fields, which were laid out in beautiful groves and gardens, are now naked plains, smoking with sulphur, or encumbered with hills that have been thrown up by eruptions of fire. The works of art lie in no less disorder than those of nature, for that which was once the most beautiful spot of Italy, covered with temples and palaces, adorned by the greatest of the Roman commonwealth, embellished by many of the Roman emperors, and celebrated by the best of their poets, has now nothing to show but the ruins of its ancient splendor, and a great magnificence in confusion. The mole of Puteoli has been mistaken by several authors for Caligula's bridge. They have all been led into this error from the make of it, because it stands on arches. But to pass over the many arguments that may be brought against this opinion, I shall here take away the foundation of it, by setting down an inscription mentioned by Julius Capitolinus in the life of Antoninus Pius, who was the repairer of this mole. Imp. Cæsari. Divi. Hadriani. filio. Divi. Trajani. Parthici. Nepoti. Divi. Nerve. pronepoti. T. Act. Hadriano. Antonino. Aug. Pio. &c. quod super cætera beneficia ad hujus etiam tutelam portús, Pilarum viginti molem cum sumptu fornicum reliquo ex Erario suo largitus est. It would have been very difficult to have made such a mole as this of Puteoli, in a place where they had not so natural a commodity as the earth of Puzzuola, which immediately hardens in the water, and after a little lying in it, looks rather like stone than mortar. It was this that gave the ancient Romans an opportunity of making so many encroachments on the sea, and of laying the foundations of their villas and palaces within the very borders of it, as Horace has elegantly described it more than once. About four years ago they dug up a great piece of marble near Puzzuola, with several figures and letters engraven round it, which have given occasion to some disputes among the antiquaries. But they all agree that it is the pedestal of a statue erected to Tiberius by the fourteen cities of Asia, which were flung down by an earthquake; the same that, according to the opinion of many learned men, happened at our Saviour's crucifixion. They have found in the letters, which are still legible, the names of the several cities, and discover in each figure something particular to the city, of which L. 2. O. 18. L. 3.0. 1. L. 3. O. 24. Epist. l. 1. b Vid. Gronovium, Fabretti, Bulifon, &c. it represents the genius. There are two medals of Tiberius stamped on the same occasion, with this inscription to one of them, Civitatibus Asia Restitutis. The emperor is represented in both sitting, with a patera in one hand and a spear in the other. It is probable this might have been the posture of the statue, which in all likelihood does not lie far from the place where they took up the pedestal; for they say there were other great pieces of marble near it, and several of them inscribed, but that nobody would be at the charges of bringing them to light. The pedestal itself lay neglected in an open field when I saw it. I shall not be particular on the ruins of the amphitheatre, the ancient reservoirs of water, the Sibyl's grotto, the Centum camera, the sepulchre of Agrippina, Nero's mother, with several other antiquities of less note, that lie in the neighbourhood of this bay, and have been often described by many others. I must confess, after having surveyed the antiquities about Naples and Rome, I cannot but think that our admiration of them does not so much arise out of their greatness as uncommonness. There are indeed many extraordinary ruins, but I believe a traveller would not be so much astonished at them, did he find any works of the same kind in his own country. Amphitheatres, triumphal arches, baths, grottoes, catacombs, rotundas, highways paved for so great a length, bridges of such an amazing height, subterraneous buildings for the reception of rain and snow-water, are most of them at present out of fashion, and only to be met with among the antiquities of Italy. We are therefore immediately surprised when we see any considerable sums laid out in any thing of this nature, though at the same time there is many a Gothic cathedral in England, that has cost more pains and money than several of these celebrated works. Among the ruins of the old heathen temples they showed me what they call the chamber of Venus, which stands a little behind her temple. It is wholly dark, and has several figures on the ceiling wrought in stucco, that seem to represent lust and strength by the emblems of naked Jupiters and Gladiators, Tritons and Centaurs, &c. sơ that one would guess it has formerly been the scene of many lewd mysteries. On the other side of Naples are the catacombs. These must have been full of stench and loathsomeness, if the dead bodies that lay in them were left to rot in open niches, as an eminent author of our own country imagines. But upon examining them I find they were each of them stopped up without doubt, as soon as the corpse was laid in it. For at the mouth of the niche one always finds the rock cut into little channels, to fasten the board or marble that was to close it up, and I think I did not see one which had not still some mortar sticking in it. In some I found pieces of tiles that exactly tallied with the channel, and in others a little wall of bricks, that sometimes stopped up above a quarter of the niche, the rest having been broken down. St. Proculus's sepulchre seems to have a kind of mosaic work on its covering, for I observed at one end of it several little pieces of marble ranged together after that manner. 'Tis probable they were adorned, more or less, according to the quality of the dead. One would, indeed, wonder to find such a multitude of niches unstopped, and I cannot imagine any body should take the pains to do it, who was not in quest of some supposed treasure. Baja was the winter retreat of the old Romans, that being the proper season to enjoy the Bajani Soles, and the Mollis Lucrinus; as on the contrary, Tibur, Tusculum, Preneste, Alba, Cajeta, Mons Circeius, Anxur, and the like airy mountains and promontories, were their retirements during the heats of summer. Dum nos blanda tenent jucundi stagna Lucrini, Et quæ pumiceis fontibus antra calent, Tu colis Argivi regnum Faustine coloni * Vide Hor. lib. 2. od. 6. MAR. lib. 1. Ep. 116. While near the Lucrine lake, consum'd to death, Then briny seas and tasteful springs farewel, Where fountain-nymphs confus'd with Nereids dwell, The natural curiosities about Naples are as numerous and extraordinary as the artificial. I shall set them down, as I have done the other, without any regard to their situation. The grotto del Cani is famous for the poisonous steams which float within a foot of its surface. The sides of the grotto are marked green, as high as the malignity of the vapour reaches. The common experiments are as follow: A dog, that has his nose held in the vapour, loses all signs of life in a very little time; but if carried into the open air, or thrown into a neighbouring lake, he immediately recovers, if he is not quite gone. A torch, snuff and all, goes out in a moment when dipped into the vapour. A pistol cannot take fire in it. I split a reed, and laid in the channel of it a train of gunpowder, so that one end of the reed was above the vapour, and the other at the bottom of it; and I found, though the steam was strong enough to hinder a pistol from taking fire in it, and to quench a lighted torch, that it could not intercept the train of fire when it had once begun flashing, nor hinder it from running to the very end. This experiment I repeated twice or thrice, to see if I could quite dissipate the vapour, which I did in so great a measure, that one might easily let off a pistol in it. I observed how long a dog was in expiring the first time, and after his recovery, and found no sensible difference. A viper bore it nine minutes the first time we put it in, and ten the second. When we brought it out after the first trial, it took such a vast quantity of air into its lungs, that it swelled almost twice as big as before; and it was perhaps on this stock |
