in the same city in 1491. The distinction of the Nuremberg chronicle does not consist in any superiority of design which can be claimed for it in comparison with other books of the same sort, but in the fact that here were printed, for the first time, woodcuts simply in black and white, which were looked on as complete without the aid of the colorist, and were in all essential points entirely similar to modern works. This change was brought about by the introduction of cross-hatching, or lines crossing each other at different intervals and different angles, but usually obliquely, by means of which blacks and grays of various intensity, or what is technically called color, were obtained. This was a process already in use in copperplate-engraving. In that art—the reverse of wood-engraving since the lines which are to give the impression on paper are incised into the metal instead of being left raised as in the wood-block—the engraver grooved out the crossing lines with the same facility and in the same way as the draughtsman draws them in a pen-and-ink sketch, the depth of color obtained depending in both cases on the relative closeness and fineness of the hatchings. In engraving in wood the task was much more difficult, and required greater nicety of skill, for, as in this case the crossing lines must be left in relief, the engraver was obliged to gouge out the minute diamond spaces between them. At first this was, probably, thought beyond the power of the workmen. The earliest woodcut in which these cross-hatchings appear is the frontispiece to Breydenbach's Travels, published at Mayence in 1486, which is, perhaps, the finest wood-engraving of its time. In the Nuremberg chronicle this process was first extensively employed to obtain color, and thus this volume marks the beginning
