Thus does the engraver vindicate his art. But nobody can examine a choice print without feeling that it has a merit of its own, different from any picture, and inferior only to a good picture. A work of Raphael, or any of the great masters, is better in an engraving of Longhi or Morghen than in any ordinary copy, and would probably cost more in the market. A good engraving is an undoubted work of Art; but this cannot be said of many pictures, which, like Peter Pindar’s razors, seem made only to sell. Much that belongs to the painter belongs also to the engraver, who must have the same knowledge of contours, the same power of expression, the same sense of beauty, and the same ability in drawing with sureness of sight, as if, according to Michel Angelo, he had “a pair of compasses in his eyes.” These qualities in a high degree make the artist, whether painter or engraver, naturally excel in portraits. But choice portraits are less numerous in engraving than in painting, for the reason that painting does not always find a successful translator. The earliest engraved portraits which attract attention are by Albert Dürer, who engraved his own work, translating himself. His eminence as painter was continued as engraver. Here he surpassed his predecessors,--Martin Schoen in Germany, and Mantegna in Italy,--so that Longhi does not hesitate to say that “he was the first who carried this art from infancy, in which he found it, to a condition not far from flourishing adolescence.”[149] But while recognizing his great place in the history of engraving, it is impossible not to see that he is often hard and constrained, if not unfinished. His portrait of Erasmus is justly famous, and is conspicuous among the prints exhibited in the British Museum. It is dated 1526, two years before the death of Dürer, and has helped to extend the fame of the universal scholar and approved man of letters, who in his own age filled a sphere not unlike that of Voltaire in a later century. There is another portrait of Erasmus by Holbein, often repeated; so that two great artists have contributed to his renown. That by Dürer is admired. The general fineness of touch, with the accessories of books and flowers, shows the care in its execution; but it wants expression, and the hands are far from graceful. Another most interesting portrait by Dürer, executed in the same year with the Erasmus, is Philip Melanchthon, the Saint John of the Reformation, sometimes called “The Teacher of Germany,”--_Preceptor Germaniæ_. Luther, while speaking of himself as rough, boisterous, stormy, and altogether warlike, says, “But Master Philippus moves gently and quietly along, ploughs and plants, sows and waters with pleasure, according as God hath given him His gifts richly.”[150] At the date of the print he was twenty-nine years of age, and the countenance shows the mild reformer.
