The great book, on which the printers exercised most care, was the Bible. Many editions were published; but the most important of these, in respect to the history of wood-engraving, was the Cologne Bible (Figs. 8, 9), which appeared before 1475, both because its one hundred and nine designs were, probably, after the block-books, the earliest series of engraved illustrations of Scripture, and were widely copied, and also because they show an extension of the sphere of thought and increased intellectual activity. The designers of these cuts relied less upon tradition, displayed more original feeling, and showed greater variety and vivacity in their treatment, than the artists who had engraved the _Biblia Pauperum_. The latter volume contained, as has been seen, nearly the last impression of century-old pictorial types in the mediæval conventional manner; the Cologne Bible defined conceptions of Scriptural scenes anew, and these conceptions became conventional, and re-appeared for generations in other illustrated Bibles in all parts of Europe; not, however, because of an immobility of mind characteristic of the community, as in earlier times, but partly because the printers preserved and exchanged old wood-blocks, so that the same designs from the same blocks appeared in widely distant cities, and partly because it was less costly for them to employ an inferior workman to copy the old cut, with slight variations, than to have an artist of original inventive power to design a wholly new series. Thus the Nuremberg Bible of 1482 is illustrated from the same blocks as the Cologne Bible, and the cuts in the Strasburg Bible of 1485 are poor copies of the same designs. From the marginal border which encloses the first page of the Cologne Bible it appears that wood-engraving was already looked on, not only as a means of illustrating what was said in the text, but as a means of decoration merely. Here, among the foliage and flowers, are seen running animals, and in the midst the hunter, the jongleur, the musician, the lover, the lady, and the fool--an indication of delight in nature and in the variety of human life, which, simply because it is not directly connected with the text, is the more significant of that freer range of sympathy and thought characteristic of the age. Afterward these decorative borders, often in a satiric and not infrequently in a gross vein, wholly disconnected with the text, and sometimes at strange variance with its spirit, are not uncommon. The engravings that follow this frontispiece represent the customary Scriptural scenes, and the series closes with two striking designs of the Last Judgment and of Hell. In the former angels are hurling pope, emperor, cardinal, bishop, and king into hell, and in the latter their bodies lie face to face with the souls marked with the seal of God--a satire not unexampled before this time, and indeed hardly bolder than hitherto, but of a spirit which showed that Luther was already born.
