Note 96 — BOOK I. (continued 2)

In this edition I ought to mention another zolfo (a sulphur cast) of the same pace of S. Giovanni, in possession of his excellency the Senator Prior Seratti. This, when compared with the model, corresponds line for line; there is a full display of the very difficult character of Maso's heads, and what is still more decisive, is, that it is cut, or indented, an effect that must have been produced according to the manner already described. The zolfo Durazzo, as appears from the impression, does not correspond so well; some of the flowers and ornaments of drapery are wanting; it is not equally finished, and it seems smooth on the surface. This does not derogate from its genuineness, for as several proofs were taken of the same pace, which was cut by degrees, if we find less completeness in the Durazzo proof, it is only an indication of its having been taken before the rest. And if the impressions of the cuts are not so plainly traced as in the other, I do not, therefore, conjecture that they do not exist. The zolfi of the fathers of Camaldoli already cited, seem as if they were printed, and smooth. A fragment breaking off, highly polished on the surface, the cuts were then discovered, even to the minutest lines, as many professors, even the most experienced in the art of printing, to their surprise, have witnessed; and they conjectured that the ocular illusion might arise, 1st, from the fineness of cut made with the style, or possibly with the graver, which was diminished in proportion as it passed from the sheet to the earthen mould, and from this to the zolfo; 2d, from the density of the ink, when hardened between the cuts or hollows of the zolfo; 3d, from a coat of bluish colour laid on the work, of which there remain traces, and from that which time produces both in paintings and on cards. I have not a doubt, that, if the experiment were tried on the Durazzo zolfo, the result would appear exactly the same. The extrinsic proofs of its origin, also adduced by Gori, together with the aspect of the monument, which is fresh in my memory, do not authorize me to suspect the existence of a fraud.
