Such, as will be seen by the views with which, I doubt not, almost all my readers must be familiar, is the general idea of the Gothic palaces in Venice, and it admits of very slight modification. Occasionally, as in the Ca’ d’Oro, the windows are inclosed within a square line of delicate moulding, the space within which is encrusted with marble, and entirely distinct from the string-courses, so as to give very much the impression of a plain wall veneered here and there with a window; or, again, sometimes the whole central division of the first and second stories is veneered on to a façade in which the other windows are treated constructionally but in all cases from first to last (except, as we shall see, in the Ducal Palace, and for this exception there is some explanation in its vast size and other reasons), the distinction between the centre and the wings was never lost sight of, and never forgotten. This was the great idea of all these buildings, and most perseveringly was it reproduced down to the last, when, gradually losing even the life which beautiful detail had once lent, it sank through successive stages, until at last, easily and well-nigh imperceptibly, it succumbed, without a struggle, to the rise of the Renaissance feeling, giving only in revenge to its successor, the curse of an obligation still to go on building to the last, for whatever want or on whatever occasion, with the conviction that a centre and two wings must ever be necessary to a grand façade. It so happens that, in addition to the large and purely Byzantine palaces in which this arrangement is preserved,—in a delicate manner, it is true,—there still remains one remarkable example of the period of transition from Byzantine to Gothic, in a house which forms one side of the Corte del Remer (facing the Grand Canal just above the spot where it is spanned by the Rialto), which serves to shew clearly the first attempt at translation of this Byzantine idea into Gothic.
In the principal story of this house the central feature is the entrance doorway, whose finely ornamented arch of markedly horseshoe outline is very conspicuous. On either side of this, and connected with it in one group, are two windows divided by shafts and with arches of very singular shape; it is as though a stilted semicircular arch had been suddenly turned up in the centre, not with the graceful ogee curve of later days, but with simple, hard, straight lines. Beyond these windows, one of later date, but probably inserted in the place of the original window, completes the similarity which the arrangement of the openings in this house bears to that common in all the later Gothic palaces. The arches which support the staircase in front of this house are entirely executed in brick, and are probably later in date than the house itself, though it is noticeable that they are of a very early and pure type, and that here, as generally throughout the North of Italy, the pointed arch was first used in construction, and then, some time after its first introduction, and very generally in some modified form, for ornamentation also.
And now, having so far cleared the way, let me ask my readers to go with me to the Ducal Palace, and there undertake a somewhat careful examination of its very famous design.
I shall not enter into a general description of the entire building, because, as this has undergone prodigious alterations since its first erection, it is unnecessary to do much more than refer to the two fronts, which still retain, nearly without alteration, their mediæval design, and to those portions only of the interior and courtyard which have not been altered.
