To put it to the test of experiment, however, Picart chose some designs of the earlier painters, which had not been engraved, worked at them in secret, stamped some of them on old paper, and dispersed them quietly; and no one ventured to doubt but that they had been both engraved and printed in Italy. Having by this artifice sufficiently disproved the validity of those assertions which tended to depreciate the modern engravers, M. Picart collected in one volume all the plates he had so circulated, and they were afterwards published under the name of “Picart’s innocent Impostors.” Goltzius, a celebrated engraver of an earlier period, had recourse to a somewhat similar artifice, to convince the world of the malevolent detraction of certain rival artists, who, to humble Goltzius, were accustomed to say that his works were not to be compared with those of Albert Durer, or Lucas of Leyden. He, therefore, engraved the Circumcision, after the manner of Albert Durer, stamped below with his own name and mark; some impressions were taken off on old and discoloured paper, and his name was burnt out, or otherwise effaced. This plate went thus in masquerade to Rome, Venice, and Amsterdam, and was received by all the amateurs and curious with astonishment and pleasure, and was purchased at a very high price by those who esteemed themselves too happy to have found an opportunity of possessing themselves of an engraving by Albert Durer. Soon after, the same plate appeared entire, and freshly stamped with the name and mark of Goltzius; the connoisseurs were of course greatly confused and extremely angry, and the malevolent jealousy of his rivals was exposed to the world. Marc Antonio Raimondi raised himself into notice in the following manner: many engravings by Albert Durer were brought to Venice for sale, and Raimondi was so much struck by the style and execution, that he purchased them, and set to work to copy them, counterfeiting Albert Durer’s mark, A. D. These copies appeared so similar, that they were believed to be the genuine works of Albert, and, as such, were exposed to sale, and became speedily purchased. This made Albert so indignant, that he quitted Flanders, and came to Venice, to make a complaint against Raimondi to the government; and he was forbidden in future to make use of Albert’s name or mark. The engraving of the Burgomaster Six, the patron of Rembrandt, was so much valued, and so scarce, that Beringhen could not obtain it for any money; and he, therefore, procured a copy of it to be made with a pen, and afterwards washed with Indian ink, which was in the French king’s cabinet at the time M. Gersaint wrote Rembrandt’s life, and was so excellent an imitation, that it deceived several good judges.
