silver ornaments, and sacred vessels, such as holy cups and vases, to missals and other devotional books, and to reliquaries; as well as to profane purposes, as adorning the hilts of swords, table utensils, and many kinds of female ornaments. In some kinds of ebony desks and escrutoires it was held in great request, for its little silver statues, and modelled plates, representing figures, histories, and flowers. In the cathedral of Pistoia there still remains a large silver palliotto, adorned in places with plates, on which are figured images in niello, and little scripture histories. The method was to cut with the chisel upon the silver whatever history, portrait, or flowers, was required,[91] and afterwards to fill up the hollow part of the engraving with a mixture of silver and lead, which, from its dark colour, was called, by the ancients, nigellum, which our countrymen curtailed into niello; a substance which, being incorporated with the silver, produced the effect of shadow, contrasted with its clearness, and gave to the entire work the appearance of a chiaroscuro in silver. There were many excellent niellatori, or inlayers, who cast models with this substance, such as Forzore, brother to Parri Spinelli of Arezzo, Caradosso and Arcioni of Milan;[92] and three Florentines, who rivalled each other at S. Giovanni, Matteo Dei, Antonio del Pollaiuolo, and Maso Finiguerra; specimens of whose paci, cut with wonderful accuracy, acquired for them the highest reputation.

We are to attribute to Maso, says Vasari, "the beginning of engraving upon copper," an art, which for the sake of greater perspicuity, I shall distinguish into three different states; the first of which will be found as follows. Finiguerra was in the habit of never filling the little hollows or cuts prepared in the silver plate until he had first made proof of his work. "For this purpose, as in taking a cast, he impressed them with earth, upon the top of which having thrown a quantity of liquid sulphur, they became imprinted, and filled with smoke; which, with the aid of oil, gave him the effect of the work in silver. He also produced the same with moistened paper, and with the same tint or ink, pressing it sufficiently hard with a round roller, with a smooth surface throughout. This gave them not only the effect of being printed, but that of having been designed with ink."[93] So far we quote Vasari in the preface to his Life of Marc Antonio. He adds, that in this plan Finiguerra was followed by Baldini, a Florentine goldsmith; next to whom he mentions Botticelli; and he might have added the name of Pollaiuolo. Finally, he concludes that the invention was communicated from Florence to Mantegna at Rome, and to Martino, called De Clef, in Flanders.

These proofs, the first of their kind, made by Finiguerra, have, for the most part, perished. Some, which are attributed to him, in possession of the fathers of Camaldoli, are not ascertained to be his.[94] We are assured, however, that the sulphur of the pace[95] cut for S. Giovanni in 1452, upon which he represented the Assumption of our Lady, in a variety of minute figures, is from his hand. It was formerly in the museum of the Proposto Gori, who gave a description of it in his Dittici (a treatise upon a peculiar kind of altar-pieces, tom. iii. p. 315), and it is now in the Durazzo cabinet, with a memorandum in Gori's own hand, in which he declares that he had compared it with the original.[96] Of the proofs made on paper none are ascertained to exist, with the exception of that of the Assumption recognized by the Ab. Zani, in the national collection at Paris. It was made known by him in the year 1803; and to this I may add the Epiphany, in an inferior style, but more exactly finished, which I found in the possession of the Senator Martelli, besides a duplicate belonging to S. E. Seratti. It appears from its style, the work of Finiguerra, and to have been executed before the Assumption. It is doubtful whether specimens exist in the ducal gallery, a question which I leave to the solution of abler pens than mine. We have in the Durazzo collection, the proofs or models of many silversmiths, whose names are unknown; and for many more we are indebted to Sig. Antonio Armanno, an excellent connoisseur in prints, to whom I shall have occasion to recur more than once. Following the ideas thrown out by Vasari in the passage cited, he concluded that these impressions might happen to have been confounded with pen designs, owing to the resemblance between them; he therefore sought for them in collections of designs, and, having recognized them, purchased them for Count Giacomo, his patron.

Many of these were met with in the ancient Gadi gallery at Florence; the work of artificers much inferior to Finiguerra, at least if we except two specimens not unworthy even of his hand. To these a number of others were afterwards added from different schools of Italy. Sometimes we may gather their origin from the design; sometimes with more certainty from inscriptions, and other unequivocal signs of the period. For instance, we read the following words in a Presepio,[97] engraved in reversed characters: "Dominus Philippus Stancharius fieri fecit;" where the family which is named, along with other circumstances, shew it to have been executed at Bologna. One small print represents a woman turning towards a cat; and on it is written, also in reverse, "Va in la Caneva;" in another we read Mantengave Dio; both which are either Lombard or Venetian, if we may judge from the dialect. From all this we have a right to conclude that Vasari's words, which ascribe to Finiguerra the practice of proving his works before he inserted the niello, are not to be limited to him only, or to his school. On the contrary, it appears that Caradosso, as well as all the best Italian artificers, considered it as no small portion of their art, and that they only attained correctness in the process of inlaying and modelling by dint of such proofs, and not by mere chance. Nor does Vasari's silence militate against this. He repeatedly complains, in different parts of his work, that he could not obtain sufficiently full and satisfactory information regarding the Venetian and Lombard schools; and if he confesses his ignorance of so many things pertaining to their schools of painting, it is not surprising that he should know less of their engraving.

The proofs, therefore, of the niellatori on paper are to be found in all parts of Italy, and they may be particularly known from the position of the letters, which being written on the original models in the ordinary way, appear in the impression like the eastern characters, from right to left; and in like manner the other part of the impression is seen in reverse; as for instance, a saint is seen standing on the left hand, who, from his dignity, ought to have occupied the right, and the actors all write, play music, and do every thing with the left hand. There are other signs which serve to distinguish them; because, having been pressed by hand, or with a roller, they leave no mark or furrows in the outlines; nor are we to look for that delicacy and precision in the lines that appear in impressions from under the press. They are moreover characterized by their colour, which merely consisted of lamp black and of oil, or of some other very slight tint; though both this and the preceding are dubious signs, as we shall shew. It is conjectured that proofs of a similar[98] nature were made by silver carvers, in regard to their graphic labours, and to others in which the niello was not employed. At all events they preserved them in their studies, and in those of their pupils, to whom they afforded a model; and in this way several have been handed down to our own times.

From these early efforts, the art gradually advanced, as it appears to me, until it attained what I call the second state of the impression. When the pleasing effect of these proofs was seen, the idea was struck out, of forming works in the same delicate and finished taste, and for this purpose to make use of the same means as had been until then adopted for impressions in wood. We might thus observe, that in the workshop of the goldsmith was prepared the art of chalcography, and the first labours were executed upon silver, upon tin, or, as Heineken observes, upon some composition less hard than copper. We may remark, that such was the practice of the Italians, before they cut their subjects in copper; but whatever material the first goldsmiths might adopt, it was not difficult for them to substitute for the shadow they produced by the niello, the shadow of the cut itself, and to execute the subject on the reverse, in order to receive the impression right. From that time, they proceeded gradually to refine the art. Both the roller and the press which they had then in use were very imperfect, and,
