With Dürer, at the latter end of the fifteenth century, the Book was no more than a pretext for engravings. Thausing, his biographer, says that the great artist felt the necessity of designing an Apocalypse at Rome at the time that Luther was premeditating his religious revolution in face of the worldly splendours of the pontifical court. The "Apocalypse," published in 1511 in Latin, with Gothic characters, was an album of fifteen large wood engravings. The Four Horsemen is the best of these plates, and the boldest; but in this gross fancy, in these poor halting old hacks, the fantastic and grand idea which the artist meant to convey can hardly be seen. It may be said the genius of Dürer was little adapted to vignettes, however large they were, and did not easily lend itself to the exigencies of a spun-out subject. The title of his "Apocalypse" is of its kind a curious example of German genius, but, in spite of its vigour, it does not please like an Italian headpiece or like a French or Flemish frontispiece. The other works of Dürer published in the fifteenth century, "The Life of the Virgin" and "The Passion," were also sets of prints that received a text in the sixteenth century. [Illustration: Fig. 21.--Title of the "Apocalypse," by Albert Dürer, printed in 1498.

Engraving from the "Ship of Fools."] For the rest of his illustrations Dürer belongs to the sixteenth century, and we shall have occasion to recur to his works. At present it remains to speak of a curious work printed at Basle by Bergman de Olpe in 1497, which appears to be the first comic conception of fifteenth century artists: the _Navis Stultifera_, or "Ship of Fools," of Sebastian Brandt. This work of the school of Basle lacks neither originality nor vigour. At the time when it was published its success was immense, from the strange tricks of its clowns, with fools' caps, with which every page was adorned. Alas! the best things fall under the satire of these jesters, even the Book and the lover of books, if we may judge by the sarcasms against useless publications volleyed by the personage here reproduced. "I have the first place among fools.... I possess heaps of volumes that I rarely open. If I read them, I forget them, and I am no wiser." Brunet sees in these humorous caricatures more art than is really to be found in them. Their value is owing more to their spirit and humour than to any other artistic merit. Even the engraving is singularly fitted to the subject, with its peculiar cutting, somewhat executed in hairlines. The designer was certainly not a Holbein, but he is no longer the primitive artisan of the first German plates, and his freedom is not displeasing.
