Dürer executed for the Emperor a series of most fantastic and grotesque pen-drawings, on the borders of his prayer-book, now in the Munich town-library. Alongside the solemn sentences of the breviary are whimsical monkeys and pigs, Indians and men-at-arms, satyrs and foxes, screeching devils and saints, hens and prophets, martyrs and German crones, mingled in a weird wonderland, and not inappropriate according to mediæval ideas of taste. "The Great Column" is another quaint and inexplicable engraving, which Dürer did for the Emperor in 1517, and is composed of four blocks 5-1/3 feet high. It shows two naked angels holding a large turnip, from which springs a tall column with two horrible female monsters at the base, and a horned satyr at the top, holding long garlands. The marvellous "Triumphal Arch of Maximilian" is composed of ninety-two blocks, forming an immense woodcut ten and a half feet high and nine feet wide. It shows three great towers, under which are the three gates of Praise, Nobility, and Honor and Power, with the six chained harpies of temptation, and two vigilant Archdukes in armor, and figures holding garlands and crowns. The great genealogical tree rises above the figures that represent France, Sycambria, and Troy, and bears portrait-like half-figures of the twenty-six Christian princes from whom Maximilian claimed descent, with pictures of himself and his family. There are also twenty-four minutely delicate cuts, showing the most remarkable events in the Emperor's life, accompanied with rugged explanatory rhymes by the poet-laureate. Dr. von Eye says that "the extent and difficulty of the task appear to have called forth the powers of the artist to their highest exercise. In no work of Dürer's do we find more beautiful drawing than there is here. Each single piece might be taken out and prized as an independent work of art." The master drew these very elaborate and intricate designs between 1512 and 1515; and the enormous work of engraving them was devolved upon Hieronymus Rösch of Nuremberg. During its progress the Emperor frequently visited Rösch's house in the Fraüengässlein; and it became a town saying, that "The Emperor still drives often to Petticoat Lane." On one of his visits, a number of the artist's pet cats ran into his presence; whence, it is said, arose the proverb, "A cat may look at a King." In 1516 Dürer painted a fine portrait of Wohlgemuth, now at Munich, showing a wrinkled old face lit up by bright eyes, and inscribed, "This portrait has Albert Dürer painted after his master Michael Wohlgemuth, in the year 1516, when he was 82 years old; and he lived until the year 1519, when he died, on St. Andrew's Day, early, before the sun had risen." About the same period he designed and partly executed the Pietà, which is now in the St. Maurice Gallery at Nuremberg; and carved a Virgin and Child standing on the crescent moon, similar to the one which he had engraved three years before.
