Isolated, like the ducal cities of Italy, from the desolating wars of the great powers of Europe, and like them also growing rapidly in wealth and cultivation, Nuremberg afforded a secure refuge for Art and its children. In Dürer's day the great churches of St. Sebald, St. Lawrence, and Our Lady were finished; Peter Vischer executed the exquisite and unrivalled bronze Shrine of St. Sebald; and Adam Kraft completed the fairy-like Sacrament-house, sixty feet high, and "delicate as a tree covered with hoar-frost." Intimate with these two renowned artificers was Lindenast, "the red smith," who worked skilfully in beaten copper; and their studies were conducted in company with Vischer's five sons, who, with their wives and children, all dwelt happily at their father's house. Vischer lived till a year after Dürer's death, but there is no intimation that the two artists ever met. Another eminent craftsman was the unruly Veit Stoss, the marvellous wood-carver, many of whose works remain to this day; and there was also Hans Beheim, the sculptor, "an honorable, pious, and God-fearing man;" and Bullman, who "was very learned in astronomy, and was the first to set the Theoria Planetarum in motion by clockwork;" and he who made the great alarm-bell, which was inscribed, "I am called the mass and the fire bell: Hans Glockengeiser cast me: I sound to God's service and honor." What shall we say also of Hartmann, Dürer's pupil, who invented the measuring-rod; Schoner, the maker of terrestrial globes; Donner, who improved screw machinery; and all the skilful gun-makers, joiners, carpet-workers, and silk-embroiderers? There was also the burgher Martin Behaim, the inventor of the terrestrial globe, who anticipated Columbus by sailing Eastward across the Pacific Ocean, passing through the Straits of Magellan and discovering Brazil, as early as 1485. In Germany, as in Italy, the studio of the artist, full of pure and lofty ideals, had hardly yet evolved itself from the workshop of the picture-manufacturer. Nuremberg's chief artists at this time were Michael Wohlgemuth, Dürer's master; Lucas Kornelisz, also called Ludwig Krug, who, though a most skilful engraver, was sometimes forced to adopt the profession of a cook in order to support himself; and Matthias Zagel, who was expert in both painting and engraving. Still another was the Venetian Jacopo de' Barbari, or Jacob Walch, "the master of the Caduceus," a dexterous engraver and designer, whom Dürer alludes to in his Venetian and Netherland writings. The art of engraving had been invented early in the fifteenth century, and was developing rapidly and richly toward perfection. The day of versatile artists had arrived, when men combined the fine and industrial arts in one life, and devoted themselves to making masterpieces in each department. The northern nations, unaided by classic models and traditions, were developing a new and indigenous æsthetic life, slow of growth, but bound to succeed in the long run.
