At last we rolled out of Catania. There were in the diligence, besides myself, two men and a woman, Sicilians of the secondary class. The road followed the shore, over rugged tracts of lava, the different epochs of which could be distinctly traced in the character of their vegetation. The last great flow (of 1679) stood piled in long ridges of terrible sterility, barely allowing the aloe and cactus to take root in the hollows between. The older deposits were sufficiently decomposed to nourish the olive and vine, but even here the orchards were studded with pyramids of the harder fragments, which are laboriously collected by the husbandmen. In the few favored spots which have been untouched for so many ages that a tolerable depth of soil has accumulated, the vegetation has all the richness and brilliancy of tropical lands. The palm, orange, and pomegranate thrive luxuriantly, and the vines almost break under their heavy clusters. The villages are frequent and well-built, and the hills are studded, far and near, with the villas of rich proprietors, mostly buildings of one story, with verandas extending their whole length. Looking up towards Etna, whose base the road encircles, the views are gloriously rich and beautiful. On the other hand is the blue Mediterranean and the irregular outline of the shore, here and there sending forth promontories of lava, cooled by the waves into the most fantastic forms.
We had not proceeded far before a new sign called my attention to the mountain. Not only was there a perceptible jar or vibration in the earth, but a dull, groaning sound, like the muttering of distant thunder, began to be heard. The smoke increased in volume, and, as we advanced farther to the eastward, and much nearer to the great cone, I perceived that it consisted of two jets issuing from different mouths. A broad stream of very dense white smoke still flowed over the lip of the topmost crater and down the eastern side. As its breadth did not vary, and the edges were distinctly defined, it was no doubt the sulphureous vapor rising from a river of molten lava. Perhaps a thousand yards below a much stronger column of mingled black and white smoke gushed up in regular beats or pants from a depression in the mountain-side, between two small extinct cones. All this part of Etna was scarred with deep chasms, and in the bottoms of those nearest the opening I could see the red gleam of fire. The air was perfectly still, and as yet there was no cloud in the sky.
When we stopped to change horses at the town of Aci Reale, I first felt the violence of the tremor and the awful sternness of the sound. The smoke by this time seemed to be gathering on the side towards Catania, and hung in a dark mass about half-way down the mountain. Groups of the villagers were gathered in the streets which looked upward to Etna and discussing the chances of an eruption. “Ah,” said an old peasant, “the Mountain knows how to make himself respected. When he talks, everybody listens.” The sound was the most awful that ever met my ears. It was a hard, painful moan, now and then fluttering like a suppressed sob, and had, at the same time, an expression of threatening and of agony. It did not come from Etna alone. It had no fixed location; it pervaded all space. It was in the air, in the depths of the sea, in the earth under my feet, everywhere, in fact; and as it continued to increase in violence I experienced a sensation of positive pain. The people looked anxious and alarmed, although they said it was a good thing for all Sicily; the last year they had been in constant fear from earthquakes, and an eruption invariably left the earth quiet for several years. It is true that during the past year parts of Sicily and Calabria have been visited with severe shocks, occasioning much damage to property. A merchant of this city [Messina] informed me yesterday that his whole family had slept for two months in the vaults of his warehouse, fearing that their residence might be shaken down in the night.
As we rode along from Aci Reale to Taormina, all the rattling of the diligence over the rough road could not drown the awful noise. There was a strong smell of sulphur in the air, and the thick pants of smoke from the lower crater continued to increase in strength. The sun was fierce and hot, and the edges of the sulphureous clouds shone with a dazzling whiteness. A mounted soldier overtook us, and rode beside the diligence, talking with the postilion. He had been up to the mountain, and was taking his report to the governor of the district.
The heat of the day and the continued tremor of the air lulled me into a sort of doze, when I was suddenly aroused by a cry from the soldier and the stopping of the diligence. At the same time there was a terrific peal of sound, followed by a jar that must have shaken the whole island. We looked up to Etna, which was fortunately in full view before us. An immense mass of snow-white smoke had burst up from the crater, and was rising perpendicularly into the air, the rounded volumes rapidly whirling one over the other, yet urged with such impetus that they only rolled outward after they had ascended to an immense height. It might have been one minute or five, for I was so entranced by this wonderful spectacle that I lost the sense of time, but it seemed instantaneous (so rapid and violent were the effects of the explosion), when there stood in the air, based on the summit of the mountain, a mass of smoke four or five miles high, and shaped precisely like the Italian pine-tree.
Words cannot paint the grandeur of this mighty tree. Its trunk of columned smoke, one side of which was silvered by the sun, while the other, in shadow, was lurid with red flame, rose for more than a mile before it sent out its cloudy boughs. Then parting into a thousand streams, each of which again threw out its branching tufts of smoke, rolling and waving in the air, it stood in intense relief against the dark blue of the sky. Its rounded masses of foliage were dazzlingly white on one side, while, in the shadowy depths of the branches, there was a constant play of brown, yellow, and crimson tints, revealing the central shaft of fire. It was like the tree celebrated in the Scandinavian sagas, as seen by the mother of Harold Hardrada,—that tree whose roots pierced through the earth, whose trunk was of the color of blood, and whose branches filled the uttermost corners of the heavens.
The outburst seemed to have relieved the mountain, for the tremors were now less violent, though the terrible noise still droned in the air, and earth, and sea. And now, from the base of the tree, three white streams slowly crept into as many separate chasms, against the walls of which played the flickering glow of the burning lava. The column of smoke and flame was still hurled upward, and the tree, after standing about ten minutes,—a new and awful revelation of the active forces of nature,—gradually rose and spread, lost its form, and, slowly moved by a light wind (the first that disturbed the dead calm of the day), bent over to the eastward.
We resumed our course. The vast belt of smoke at last arched over the strait, here about twenty miles wide, and sank towards the distant Calabrian shore. As we drove under it, for some miles of our way, the sun was totally obscured, and the sky presented the singular spectacle of two hemispheres of clear blue, with a broad belt of darkness drawn between them. There was a hot, sulphureous vapor in the air, and showers of white ashes fell from time to time. We were distant about twelve miles, in a straight line, from the crater, but the air was so clear, even under the shadow of the smoke, that I could distinctly trace the downward movement of the rivers of lava.
This was the eruption, at last, to which all the phenomena of the morning had been only preparatory. For the first time in ten years the depths of Etna had been stirred, and I thanked God for my detention at Malta, and the singular hazard of travel which had brought me here, to his very base, to witness a scene the impression of which I shall never lose to my dying day. Although the eruption may continue, and the mountain pour forth fiercer fires and broader tides of lava, I cannot but think that the first upheaval, which lets out the long-imprisoned forces, will not be equalled in grandeur by any later spectacle.
After passing Taormina, our road led us under the hills of the coast, and although I occasionally caught glimpses of Etna, and saw the reflection of fire from the lava which was filling up his savage ravines, the smoke at last encircled his waist, and he was then shut out of sight by the intervening mountains. We lost a bolt in the deep valley opening to the sea, and during our stoppage I could still hear the groans of the mountain, though farther off and less painful to the ear. As evening came on, the beautiful hills of Calabria, with white towns and villages on their sides, gleamed in the purple light of the setting sun. We drove around headland after headland, till the strait opened, and we looked over the harbor of Messina to Cape Faro and the distant islands of the Tyrrhene Sea.
