the crater. From one vast rent in the soil a towering pillar of white smoke pours out with a loud hissing noise, and blows away in wreaths and coils over the dark surface of the cliff.
There is something curiously arresting in this quick passage from a green glade carpeted with flowers to the calcined ash and the grey desolation of this broken hillside. Of vegetation there is almost none, except a stunted heather which creeps hardily towards the blast hole. A little way off, towards the right, lies a level space sunk beneath the surrounding land, not unlike the fashion of an asphalt skating rink, so even in its surface that it resembles the work of man, and one strolls towards it to discover with what purpose anyone had dared to tamper with the soil in a spot where so thin a crust lies over bottomless pits of fire. But when one steps out upon the level flat, it reveals itself at once to be no human work. The guide stamps with his foot, and remarks that the sound is hollow. It is indeed, most unpleasantly so. He jumps upon it, and the surface quivers. You beg him to spare you further demonstrations, and walking gingerly on tiptoe, wishing at each step that you were safe in Regent Street once more, you follow him out towards the middle of this devilish crust, which rocks so easily and covers something which you hope devoutly you may never see. Midway in the expanse the fellow pauses in triumph—he has reached what he is confident will please you. He is standing by a hole, just such an opening as is made in a frozen lake in winter for the watering of animals. From it there emerges a little vapour and a curious low sound, like that which a child will make with pouting lips. The guide grins, crouching by the opening; you, on the other hand, hang back, in doubt whether the crust may not break off and suddenly enlarge the hole. You are encouraged forwards, and at last, peering nervously down the hole, you see with keen and lively interest that the crust appeared to have about the thickness of your walking-stick, at which depth there is a lake of boiling mud. The grey mud stirs and seethes in the round vent-hole, rising and falling, while on its surface the gas collects slowly into a huge bubble, which forms and bursts and then collects again.
For my part I do not deny that the sight fascinated me, but it deprived me of all wish to tread further on that shaking crust, and I sped back as lightly as I might, wishing all the way for wings, to where there was at least sound, green earth for a footing, in place of pumice stone and hardened mud, which some day, surely, will fly into splinters, and leave the seething, steaming lake once more open to the heavens.
POZZUOLI.
From the hillside just beyond the gate of the Solfatara one gazes down on the town of Pozzuoli, brown and ancient, looking, I do not doubt, much the same unto this hour as when the Apostle Paul landed there from the Castor and Pollux, a ship of Alexandria which had wintered in the Island of Melita. But if the town itself, the very houses clustered on the hill, preserve the aspect which they bore twenty centuries ago, so much cannot be said for the sea-front, which is vastly changed. Pozzuoli in those days must have rung with the noise of ships entering or departing. Its quays were clamorous with all the speeches of the East; its great trade in corn needed long warehouses near the water's edge; its amphitheatre was built for the games of a people numbering many thousands. But now the little boats which come and go are too few to break the long silence of the city, and there are scarce any other noises in the place than the shout of children at their games, or the loud crack of the vetturino's whip as the strangers rattle through the streets on their way to Baiæ.
It was the fall of Capua which made the trade of Pozzuoli, and it was the rise of Ostia that destroyed it. Capua, long the first town of Italy by reason of its commerce and its luxury, lost that pre-eminence in the year 211 B.C., when the Romans avenged the adhesion of the city to the cause of Hannibal. That act of punishment made Rome the chief mart of merchants from the East, and the nearest port to the Eternal City being Pozzuoli, the trade flowed thither naturally. Naples no doubt had a finer harbour; but Naples was not in Roman hands, while Pozzuoli was. Ostia, before the days of the Emperor Claudius, who carried out great works there, was a port of smallest consequence. Thus the harbour of Pozzuoli was continually full of ships. They came from Spain, from Sardinia, from Elba, bringing iron, which was wrought into fine tools by cunning workmen of the town; from Africa, from Cyprus, and all the trading ports of Asia Minor and the isles of the Ægean. Thither came also the merchants of Phœnicia, bringing with them all those gorgeous wares which moved the prophet Ezekiel to utter so great a chant of glory and its doom. "Tarshish was thy merchant by reason of the multitude of all kinds of riches; with silver, iron, tin, and lead they traded in thy fairs. … These were thy merchants in all sorts of things, in blue clothes and broidered work and in chests of rich apparel, bound with cords and made of cedar among thy merchandise. The ships of Tarshish did sing of thee in thy market. Thou wast replenished and made very glorious in the midst of the seas." All that most noble description of the commerce of Tyre returns irresistibly upon the mind when one looks back on the greatness of Pozzuoli, where the Tyrians themselves had a mighty factory and all the nations of the East brought their wares for sale. Most of all the town rejoiced when the great fleet hove in sight which came each year from Egypt in the spring. Seneca has left us a description of the stir. The fleet of traders was preceded some way in advance by light, swift sailing ships which heralded its coming. They could be known a long way off, for they sailed through the narrow strait between Capri and the mainland with topsails flying, a privilege allowed to none but ships of Alexandria. Then all the town made ready to hasten to the water's edge, to watch the sailors dancing on the quays, or to gloat over the wonders which had travelled thither from Arabia, India, and perhaps even far Cathay.
Well, all this is an old story now—too old, perhaps, to be of any striking interest—yet here upon the shore is still the vast old Temple of Serapis, the Egyptian deity whom the strangers worshipped. One knows not by what slow stages the Egyptians departed and the ancient temple was deserted. The only certain fact is that at some period the whole inclosure was buried deep beneath the sea, and after long centuries raised up again by some fresh movement of the swaying shore.
COLUMNS IN THE SERAPEON, POZZUOLI.
Strange as this seems to those who have not watched the perpetual heavings and subsidences of a volcanic land, the testimony of the fact is unmistakably in sight of all. For the sacred inclosure once hallowed to the rite of Serapis is still not allotted to any other purpose; and the visitor who enters it finds many of the ancient columns still erect. It is a vast quadrangle, once paved with squares of marble. There was a covered peristyle, and in the centre another smaller temple. Many of the columns of fine marble which once adorned the abode of the goddess were reft from her in the last century, when the spot was cleared of all the soil and brushwood which had grown up about it; but three huge pillars of cipollino, once forming part of the pronaos, are still erect; and what is singular about them is that, beginning at a height of some twelve feet from the ground and extending some nine feet further up, the marble is honeycombed with holes, drilled in countless numbers deep into the round surface of the columns.
There is no animal in earth or air which will attack stone in this destructive manner; but in the sea there is a little bivalve, called by naturalists "lithodomus," whose only happiness lies in boring. This animal is still found plentifully in the Bay of Baiæ. His shells still lie in the perforations of the columns; and it is thus demonstrated that the ancient temple must have been plunged beneath the sea, that it lay there long ages, till at length some fresh convulsion reared it up once more out of the reach of fish. Surely few buildings have sustained so strange a fate!
The holes drilled by the patient lithodomus, as I have said, do not extend through the whole height of the column, but have a range of about nine feet only, which is thus the measure of the space left for the operations of the busy spoiler. Above the ring of perforations one sees the indications of ordinary weathering, so that the upper edge of the holes doubtless marks the level of high water, and the summit of the columns stood up above the waves. But one does not see readily what protected the lower portion of the marble. Possibly, before the land swayed downwards something fell which covered them.
In the twelfth century the Solfatara broke forth into eruption for the last time. The scoriæ and stones fell thick in Pozzuoli,
