piazza it has four arches on the ground story, which is divided from the next stage by an arcaded string-course. This second stage has three windows only over the four arches below; and another very noticeable irregularity is, that one of these windows, and that not the central, has a pedimental canopy above its arch, and has more shafts than the others. The central window has been modernized to some extent, but this was the Ringhiera, and the balcony still remains, though looking more modern than the rest of the front. Some of the arches of these windows are very noticeable; for though they are semicircular, the back of the stones which form them is cut with a different sweep, so as to produce an outer pointed line, and thus to leave an impression on the eye of absolutely pointed windows. Another arcaded corbel-table finishes the façade, or rather ought to finish it, for above this some barbarian has added another stage, nearly to the destruction of the effect of the building.[78] North of this façade a great plain tower of rough stone recalls to recollection those of Bergamo and Brescia; it boasts of an immense clock and some faint traces of painting, and is left unfinished at the top. The whole of this façade (with the exception of the campanile) is built of red, white, and dark grey marbles, which are very carefully and effectively contrasted in their arrangement; the courses are very irregular in their widths, and apparently arranged upon no systematic rule. The opposite (east) side of the Broletto is very similar, but one of its windows is remarkable for the way in which the shafts are knotted together in the centre. This is not at all an uncommon feature in Italian pointed, and I have often wondered how it is that the eye is not at once disgusted with it, instead of being, as it usually is, pleased. I take it to be a justifiable device on some such ground as this: it takes much labour and skill to cut several shafts out of one block of marble, but all this labour and skill is unthought of, if they are entirely separated, or held together by a band which might perchance be made of some other material; this knot therefore is devised as the only means of explaining to us that the shafts so carved have really been accomplished with a very great expenditure of time and patience and skill, and do not depend upon any artificial band for the firmness with which they are all united in one. The capitals of all the columns in this Broletto are very well carved.
