Chapter XXXI: Section XLV: That masonry changes at the centre of the eighth arch from

the sea angle on the Piazzetta side. It has been of comparatively small stones up to that point; the fifteenth century work instantly begins with larger stones, "brought from Istria, a hundred miles away." [Footnote: The older work is of Istrian stone also, but of different quality.] The ninth shaft from the sea in the lower arcade, and the seventeenth, which is above it, in the upper arcade, commence the series of fifteenth century shafts. These two are somewhat thicker than the others, and carry the party-wall of the Sala del Scrutinio. Now observe, reader. The face of the palace, from this point to the Porta della Carta, was built at the instance of that noble Doge Mocenigo beside whose tomb you have been standing; at his instance, and in the beginning of the reign of his successor, Foscari; that is to say, circa 1424. This is not disputed; it is only disputed that the sea facade is earlier; of which, however, the proofs are as simple as they are incontrovertible: for not only the masonry, but the sculpture, changes at the ninth lower shaft, and that in the capitals of the shafts both of the upper and lower arcade: the costumes of the figures introduced in the sea facade being purely Giottesque, correspondent with Giotto's work in the Arena Chapel at Padua, while the costume on the other capitals is Renaissance-Classic: and the lions' heads between the arches change at the same point. And there are a multitude of other evidences in the statues of the angels, with which I shall not at present trouble the reader.
