Nor is this interior without effect on the minds of the people. At every hour of the day there are groups collected before the various shrines, and solitary worshipers scattered through the darker places of the church, evidently in prayer both deep and reverent, and, for the most part, profoundly sorrowful. The devotees at the greater number of the renowned shrines of Romanism may be seen murmuring their appointed prayers with wandering eyes and unengaged gestures; but the step of the stranger does not disturb those who kneel on the pavement of St. Mark's; and hardly a moment passes from early morning to sunset in which we may not see some half-veiled figure enter beneath the Arabian porch, cast itself into long abasement on the floor of the temple, and then rising slowly with more confirmed step, and with a passionate kiss and clasp of the arms given to the feet of the crucifix, by which the lamps burn always in the northern aisle, leave the church, as if comforted....
It must therefore be altogether without reference to its present usefulness, that we pursue our inquiry into the merits and meaning of the architecture of this marvelous building; and it can only be after we have terminated that inquiry, conducting it carefully on abstract grounds, that we can pronounce with any certainty how far the present neglect of St. Mark's is significative of the decline of the Venetian character, or how far this church is to be considered as the relic of a barbarous age, incapable of attracting the admiration, or influencing the feelings of a civilized community. Now the first broad characteristic of the building, and the root nearly of every other important peculiarity in it, is its confessed incrustation. It is the purest example in Italy of the great school of architecture in which the ruling principle is the incrustation of brick with more precious materials. Consider the natural circumstances which give rise to such a style. Suppose a nation of builders, placed far from any quarries of available stone, and having precarious access to the mainland where they exist; compelled therefore either to build entirely with brick, or to import whatever stone they use from great distances, in ships of small tonnage, and for the most part dependent for speed on the oar rather than the sail. The labor and cost of carriage are just as great, whether they import common or precious stone, and therefore the natural tendency would always be to make each shipload as valuable as possible. But in proportion to the preciousness of the stone, is the limitation of its possible supply; limitation not determined merely by cost, but by the physical conditions of the material, for of many marbles pieces above a certain size are not to be had for money. There would also be a tendency in such circumstances to import as much stone as possible ready sculptured, in order to save weight; and therefore, if the traffic of their merchants led them to places where there were ruins of ancient edifices, to ship the available fragments of them home. Out of this supply of marble, partly composed of pieces of so precious a quality that only a few tons of them could be on any terms obtained, and partly of shafts, capitals, and other portions of foreign buildings, the island architect has to fashion, as best he may, the anatomy of his edifice.
HOW THE OLD CAMPANILE WAS BUILT[48]
BY HORATIO F. BROWN
The wide discrepancy of the dates, 888 to 1148, may perhaps be accounted for by the conjecture that the work of the building [the Campanile] proceeded slowly, either with a view to allowing the foundations to consolidate, or owing to lack of funds, and that the chroniclers recorded each resumption of work as the beginning of the work. One point may, perhaps, be fixt. The Campanile must have been some way above ground by the year 997, for the hospital founded by the sainted Doge, Pietro Orseolo, which is said to have been attached to the base of the tower, was consecrated in that year. The Campanile was finished, as far as the bell-chamber at least, in 1148, under the Doge Domenico Moresini, whose sarcophagus and bust surmount the portal of the San Nicoll del Lido.
The chroniclers are at variance among themselves as to the date of the foundation, nor has an examination of the foundations themselves led to any discovery which enables us to determine that date; but one or two considerations would induce us to discard the earlier epochs. The foundations must have been designed to carry a tower of the same breadth, tho possibly not of the same height, as that which has recently fallen. But in the year of 888 had the Venetians such a conception of their greatness as to project a tower far more massive than any which had been hitherto constructed in Italy? Did they possess the wealth to justify them in such an enterprise? Would they have designed such a tower to match St. Mark's, which was at that time a small church with walls of wood? It is more probable that the construction of the Campanile belongs to the period of the second church of St. Mark, which was begun after the fire of 976 and consecrated in 1094.
The height of the Campanile at the time of its fall was 98.60 meters (322 ft.), from the base to the head of the angel, tho a considerable portion of this height was not added till 1510; its width at the base of the shaft 12.80 meters (35 ft. 2 in.), and one meter (3 ft. 3 in.) less at the top of the shaft. The weight has been calculated at about 18,000 tons.
Thanks to excavations at the base of the tower made by Com. Giacomo Boni, at the request of Mr. C. H. Blackall, of Boston, U. S. A., in the year 1885, a report of which was printed in the Archivio Veneto, we possess some accurate knowledge about a portion of the foundation upon which this enormous mass rested.
The subsoil of Venice is composed of layers of clay, sometimes traversed by layers of peat, overlying profound strata of watery sand. This clay is, in places, of a remarkably firm consistency; for example, in the quarter of the town known as Dorsoduro or "hard-back," and at the spot where the Campanile stood. A bore made at that point brought up a greenish, compact clay mixed with fine shells. This clay, when dried, offered the resisting power of half-baked brick. It is the remarkable firmness of this clay which enabled the Venetians to raise so ponderous a structure upon so narrow a foundation.
