It is a morning of alternate sun and shadow. The clouds are flying low across the city, so that now one dome and now another flashes into light and the orange groves shine green and gold among the square white houses. All the high range of the Sorrento mountains lies in shadow, but on the sea the colours are glowing warm and bright, here a tender blue, there deepening into grey, and again, nearer into shore, a marvellous rich tint which has no name, but is azure and emerald in a single moment. Away across the crescent of the gulf a crowd of fishing boats are putting forth from Torre del Greco or Torre dell' Annunziata. Even at this distance one can see how they set their huge triangular sails and scatter, some one way, some another, searching each perhaps for his favourite volcanic shoal; for the largest fish lurk always in the hollows of those lava reefs which have from time to time burst out of the bottom of the bay. Some, perhaps, are sailing for the coral fishery upon the coast of Africa, to which great numbers go still in this month of April out of all the harbours beneath Vesuvius, though the profits are not what they were, and the trade is falling upon evil days. As for the mountain, he has cleared himself of clouds, and from his summit a heavy coil of smoke uncurls itself lazily and spreads like a pennant stretching far across the sky.

All these things and more I have time to notice while I trudge along above the housetops of the city, those flat roofs named astrici which are such pleasant lounges on the summer evenings when the blue bay is dotted over with white sails and the shadows deepen on the flanks of Vesuvius or the distant line of the Sorrento coast. At length the road approaching the ridge of hill whose point forms the headland of Posilipo drops swiftly, and I find myself in face of a short ascent leading to the mouth of the very ancient grotto by which, these two thousand years and more, those who fared from Naples unto Pozzuoli have saved themselves the trouble of the hill.

It is absolutely necessary to pause and consider this hill, to which so much of the rare beauty of Naples is to be attributed. For the moment I set aside its legends and traditions, and turn my attention to the eminence itself. It is a cliff of yellow rock, whose consistency somewhat resembles sandstone, evidently worked without much difficulty, since it has been quarried out into vast cavities. The rock is tufa. It is a volcanic product, and forms the staple not only of the headland, but also of all the site of Naples and the rising ground behind it up to the base of the blue Apennines, which are seen continually towering in the distance beyond Vesuvius.

Thus at Naples one may distinguish between the eternal hills and those which have no title to the name. Of the latter is Posilipo, formed as I said out of volcanic ash. That ash was ejected underneath the sea, and having been compacted into rock by the action of the water was upreared by some convulsion long since forgotten. It is an intrusion on the landscape—a very ancient one, certainly—but it has nothing to do with the great mountain-chain which hems in the Neapolitan Campagna and ends at last in the Sorrento peninsula and Capri. All the most fertile plain which lies within that barrier was once beneath the sea, which flowed up to the bases of the mountains. There is no doubt about it. The rock of Posilipo contains shells of fish now living in the bay. From Gaeta to Castellammare stretched one wide inlet of the sea. But underneath the water volcanic ash was being cast out, as it is still at certain spots within the bay; the heaps of ash and pumice stone grew into shoals and reefs, were uplifted into hills, the sea flowed back from its uptilted bed, and the coasts of Naples and of Baiæ assumed some outline roughly similar to that which they possess at present.

Of course all this is very ancient history, far beyond the ken of written records, or even the faintest whisper of tradition, unless, indeed, in the awe with which ancient writers alluded to the Phlegræan fields, fabled in old time to be the gate of hell, we may detect some lingering memory of the horrible convulsion which drove back the sea, and out of its deserted bed reared up this wilderness of ash and craters. But speculations of this kind are rather idle. We had better turn towards the grottoes, which are, at least in part, the work of men whose doings on this earth are known to history. The one, of course, is wholly modern, a construction of our own age for the accommodation of the steam tramway; but the other, through which one walks or drives, is certainly as old as the Emperor Augustus, and has sometimes been supposed to possess an antiquity far greater than that.

It seems remarkable that the Romans should have esteemed it easier to bore through the cliff than to make a road across the headland. Indeed, there were villas on Posilipo, and there must surely have been a road of some sort from very early times, though it must be admitted that the founders of Naples did not go to Pozzuoli by the coast as we do. The old road climbed up directly from the city to Antignano, in the direction of Camaldoli, and kept along the ridge as far as possible. The coast road began to be used when the tunnel had been made. Still there must have been at least a track across the headland, and one wonders why the Romans did not improve it, in preference to boring underground. The ease with which the soft stone can be worked may account partially for their choice; but it is not to be forgotten that numberless caves, whether natural or artificial, exist in the cliffs at Posilipo and Pizzofalcone, giving occasion to the quick fancy of the Neapolitans to devise wild tales of buried treasure and of strange fierce beasts which guard it from the greed of men. The old legends of the Cimmerians who dwelt in dark caverns of the Phlegræan fields present themselves to mind in this connection, and without following out this mysterious subject further into the mists which envelope it, we may recognise the possibility that some among these caverns are far older than is commonly believed. Of course the preference of the Romans for tunnelling is explained at once, if we may suppose that by enlarging existing caverns they found their tunnel already partly made.
