Of these palaces, certainly the most striking by far are the Ca’ Loredan, the Ca’ Farsetti, and the Fondaco de’ Turchi. They all agree singularly in the general idea of their design, and consist of a grand scheme of arcading over the entire front. Divided generally into two stories in height, they are again divided in a marked manner in width into a centre and wings. This division is effected solely by a great difference in the spans of the arches forming the arcades, which in the wings are much narrower than in the central division. In the upper arcade the spaces between the columns, and indeed the whole arrangement, are often studiously unlike those in the lower range; but, at the same time, there is so very much similarity in the detail of the whole, that this variety, far from being perceived as an irregularity or a fault, does in truth just suffice to give force and vitality to what might otherwise appear to be monotonous and too often repeated, and recalls to mind not a little the very similar kind of difference between the upper and lower order of shafts already described in the west front of S. Mark’s. We cannot do better than take, as an example of the finest type of a Byzantine palace, the magnificent, though now desolate, decaying, and ruined façade of the Fondaco de’ Turchi, once the palace of the Dukes of Ferrara. The whole front of this was originally cased with a thin facing of marble, like the coeval works at S. Mark’s--a kind of decoration which, neglected as this fine relic has been for years, we cannot be surprized to find almost altogether destroyed; small fragments do, however, still here and there remain to tell of the original magnificence of the work. The lower stage of the Fondaco consists of a continuous arcade of ten open arches, with three narrower arches at either end, forming the wings, so to speak; the upper stage has eighteen arches in the centre, and four in each wing. In the wings the piers supporting the arches are, I think, all moulded pilasters; in the centre all the arches rest upon columns; and throughout the whole building the arches, which are all semicircular, are considerably stilted. The entire building is constructed in brick, which was originally, as I have before said, covered all over with a thin veneer of marble; in the spandrels of all the arches this is relieved by small circular medallions delicately carved, and over the upper stage is a string-course, above which there would seem to have been a long series of slightly sunk panels with round-arched heads, filled in with delicately arranged and beautifully sculptured patterns in marble. These panels are immediately below the eaves of the roof. Many of the abaci and string-courses, and all the thin pieces of marble which form the soffeits of the arches, have their projections finished either with a nail-head or dentil moulding, and between the shafts of the upper stage there are traces of balconies.[42]
