SECTION V. What circumstances directed the peculiar arrangement of this great belt of sediment in the earliest times, it is not here the place to inquire. It is enough for us to know that from the mouths of the Adige to those of the Piave there stretches, at a variable distance of from three to five miles from the actual shore, a bank of sand, divided into long islands by narrow channels of sea. The space between this bank and the true shore consists of the sedimentary deposits from these and other rivers, a great plain of calcareous mud, covered, in the neighborhood of Venice, by the sea at high water, to the depth in most places of a foot or a foot and a half, and nearly everywhere exposed at low tide, but divided by an intricate network of narrow and winding channels, from which the sea never retires. In some places, according to the run of the currents, the land has risen into marshy islets, consolidated, some by art, and some by time, into ground firm enough to be built upon, or fruitful enough to be cultivated: in others, on the contrary, it has not reached the sea-level; so that, at the average low water, shallow lakelets glitter among its irregularly exposed fields of seaweed. In the midst of the largest of these, increased in importance by the confluence of several large river channels towards one of the openings in the sea bank, the city of Venice itself is built, on a clouded cluster of islands; the various plots of higher ground which appear to the north and south of this central cluster, have at different periods been also thickly inhabited, and now bear, according to their size, the remains of cities, villages, or isolated convents and churches, scattered among spaces of open ground, partly waste and encumbered by ruins, partly under cultivation for the supply of the metropolis.
SECTION VI. The average rise and fall of the tide is about three feet (varying considerably with the seasons; [Footnote: Appendix III, "Tides of Venice.">[) but this fall, on so flat a shore, is enough to cause continual movement in the waters, and in the main canals to produce a reflux which frequently runs like a mill stream. At high water no land is visible for many miles to the north or south of Venice, except in the form of small islands crowned with towers or gleaming with villages: there is a channel, some three miles wide, between the city and the mainland, and some mile and a half wide between it and the sandy breakwater called the Lido, which divides the lagoon from the Adriatic, but which is so low as hardly to disturb the impression of the city's having been built in the midst of the ocean, although the secret of its true position is partly, yet not painfully, betrayed by the clusters of piles set to mark the deep-water channels, which undulate far away in spotty chains like the studded backs of huge sea-snakes, and by the quick glittering of the crisped and crowded waves that flicker and dance before the strong winds upon the unlifted level of the shallow sea. But the scene is widely different at low tide. A fall of eighteen or twenty inches is enough to show ground over the greater part of the lagoon; and at the complete ebb the city is seen standing in the midst of a dark plain of seaweed, of gloomy green, except only where the larger branches of the Brenta and its associated streams converge towards the port of the Lido. Through this salt and sombre plain the gondola and the fishing-boat advance by tortuous channels, seldom more than four or five feet deep, and often so choked with slime that the heavier keels furrow the bottom till their crossing tracks are seen through the clear sea water like the ruts upon a. wintry road, and the oar leaves blue gashes upon the ground at every stroke, or is entangled among the thick weed that fringes the banks with the weight of its sullen waves, leaning to and fro upon the uncertain sway of the exhausted tide. The scene is often profoundly oppressive, even at this day, when every plot of higher ground bears some fragment of fair building: but, in order to know what it was once, let the traveller follow in his boat at evening the windings of some unfrequented channel far into the midst of the melancholy plain; let him remove, in his imagination, the brightness of the great city that still extends itself in the distance, and the walls and towers from the islands that are near; and so wait, until the bright investiture and, sweet warmth of the sunset are withdrawn from the waters, and the black desert of their shore lies in its nakedness beneath the night, pathless, comfortless, infirm, lost in dark languor and fearful silence, except where the salt runlets plash into the tideless pools, or the seabirds flit from their margins with a questioning cry; and he will be enabled to enter in some sort into the horror of heart with which this solitude was anciently chosen by man for his habitation. They little thought, who first drove the stakes into the sand, and strewed the ocean reeds for their rest, that their children were to be the princes of that ocean, and their palaces its pride; and yet, in the great natural laws that rule that sorrowful wilderness, let it be remembered what strange preparation had been made for the things which no human imagination could have foretold, and how the whole existence and fortune of the Venetian nation were anticipated or compelled, by the setting of those bars and doors to the rivers and the sea. Had deeper currents divided their islands, hostile navies would again and again have reduced the rising city into servitude; had stronger surges beaten their shores, all the richness and refinement of the Venetian architecture must have been exchanged for the walls and bulwarks of an ordinary sea-port. Had there been no tide, as in other parts of the Mediterranean, the narrow canals of the city would have become noisome, and the marsh in which it was built pestiferous. Had the tide been only a foot or eighteen inches higher in its rise, the water-access to the doors of the palaces would have been impossible: even as it is, there is sometimes a little difficulty, at the ebb, in landing without setting foot upon the lower and slippery steps: and the highest tides sometimes enter the courtyards, and overflow the entrance halls. Eighteen inches more of difference between the level of the flood and ebb would have rendered the doorsteps of every palace, at low water, a treacherous mass of weeds and limpets, and the entire system of water-carriage for the higher classes, in their easy and daily intercourse, must have been done away with. The streets of the city would have been widened, its network of canals filled up, and all the peculiar character of the place and the people destroyed.
SECTION VII. The reader may perhaps have felt some pain in the contrast between this faithful view of the site of the Venetian Throne, and the romantic conception of it which we ordinarily form; but this pain, if he have felt it, ought to be more than counterbalanced by the value of the instance thus afforded to us at once of the inscrutableness and the wisdom of the ways of God. If, two thousand years ago, we had been permitted to watch the slow settling of the slime of those turbid rivers into the polluted sea, and the gaining upon its deep and fresh waters of the lifeless, impassable, unvoyageable plain, how little could we have understood the purpose with which those islands were shaped out of the void, and the torpid waters enclosed with their desolate walls of sand! How little could we have known, any more than of what now seems to us most distressful, dark, and objectless, the glorious aim which was then in the mind of Him in whose hand are all the corners of the earth! how little imagined that in the laws which were stretching forth the gloomy margins of those fruitless banks, and feeding the bitter grass among their shallows, there was indeed a preparation, and the only preparation possible, for the founding of a city which was to be set like a golden clasp on the girdle of the earth, to write her history on the white scrolls of the sea-surges, and to word it in their thunder, and to gather and give forth, in world-wide pulsation, the glory of the West and of the East, from the burning heart of her Fortitude and Splendor.
CHAPTER III. — TORCELLO.
[SECOND OF SECOND VOLUME IN OLD EDITION.]
SECTION I. Seven miles to the north of Venice, the banks of sand, which near the city rise little above low-water mark, attain by degrees a higher level, and knit themselves at last into fields of salt morass, raised here and there into shapeless mounds, and intercepted by narrow creeks of sea. One of the feeblest of these inlets, after winding for some time among buried fragments of masonry, and knots of sunburnt weeds whitened with webs of fucus, stays itself in an utterly stagnant pool beside a plot of greener grass covered with ground ivy and violets. On this mound is built a rude brick campanile, of the commonest Lombardic type, which if we ascend towards evening (and there are none to hinder us, the door of its ruinous staircase swinging idly on its hinges), we may command from it one of the most notable scenes in this wide world of ours. Far as the eye can reach, a waste of wild sea moor, of a lurid ashen gray; not like our northern moors with their jet-black pools and purple heath, but lifeless, the color of sackcloth, with the corrupted sea-water soaking through the roots of its acrid weeds, and gleaming hither and thither through its snaky channels. No gathering of fantastic mists, nor coursing of clouds across it; but melancholy clearness of space in the warm sunset, oppressive, reaching to the horizon of its level gloom. To the very horizon, on the north-east; but, to the north and west, there is a blue line of higher land along the border of it, and above this, but farther back, a misty band of mountains, touched with snow. To the east, the paleness and roar of the Adriatic, louder at momentary intervals as the surf breaks on the bars of sand; to the south, the widening branches of the calm lagoon, alternately purple and pale green, as they reflect the evening clouds or twilight sky; and almost beneath our feet, on the same field which sustains the tower we gaze from, a group of four buildings, two of them little larger than cottages (though built of stone, and one adorned by a quaint belfry), the third an octagonal chapel, of which we can see but little more than the flat red roof with its rayed tiling, the fourth, a considerable church with nave and aisles, but of which, in like manner, we can see little but the long central ridge and lateral slopes of roof, which the sunlight separates in one glowing mass from the green field beneath and gray moor beyond. There are no living creatures near the buildings, nor any vestige of village or city round about them. They lie like a little company of ships becalmed on a far-away sea.
SECTION II. Then look farther to the south. Beyond the widening branches of the lagoon, and rising out of the bright lake into which they gather, there are a multitude of towers, dark, and scattered among square-set shapes of clustered palaces, a long and irregular line fretting the southern sky.
Mother and daughter, you behold them both in their widowhood,—TORCELLO and VENICE.
