The finest of Dürer's works in portraiture was executed in 1526, and represents the grand old Jerome Holzschuher, one of the chief rulers of the city, with all the strength and keenness of his heroic nature lighting up the canvas. Enormous sums have been offered for this work; but it is still faithfully preserved in Nuremberg, and retains its original rich and vivid coloring. Another fine portrait, "like an antique bust," now in the Vienna Belvedere, shows Johann Kleeberger, the generous and charitable man who was known abroad as "the good German." Still another portrait of this year was that of the Burgomaster Jacob Müffel, a well-modelled and carefully executed likeness of one of the master's best friends. Two very famous engravings of this date portray Erasmus of Rotterdam and Philip Melanchthon. Erasmus is represented as a venerable scholar, sitting at a desk, with a pen in his hand and a soft cap on his head; and the engraving is remarkable for its admirable execution and strong character. Still, the old philosopher was not pleased with it, and sent to Sir Thomas More his portrait by Holbein, which, he said, "is much more like me than the one by the famous Albert Dürer." When Erasmus first saw the picture he said, "Oh! if I still resemble that Erasmus, I may look out for getting married," as if it gave him too young an appearance. In 1526 the wise and noble-hearted Melanchthon came to Nuremberg to establish a Protestant Latin school, and formed a close intimacy with the master, whose tender and dreamy spirit was so like his own. During their constant intercourse, the artist became strengthened and comforted in the mild and pure doctrines of the true reformation, and was quietly yet strongly influenced to abandon even the forms of Catholicism which still remained. Dürer published a fine engraving of this friend of his last years on earth, showing delicately-chiselled features, with large and tender eyes and a lofty forehead. Melanchthon wrote that in one of his frequent conversations with Dürer, the artist explained the great change which his methods had undergone, saying, "In his youth he was fond of a florid style and great combination of colors, and that in looking at his own work he was always delighted to find this diversity of coloring in any of his pictures; but afterwards in his mature years he began to look more entirely to nature, and tried to see her in her simplest form. Then he found that this simplicity was the true perfection of art; and, not attaining this, he did not care for his works as formerly, but often sighed when he looked at his pictures and thought of his incapacity."
