than by supposing that the card-makers invented the art of block-printing. On the whole, the rudeness of early German block-books must be held to be a result of the unskilfulness and tastelessness of German workmen, rather than an indication that the art was discovered by them. The engraving of the Apocalypse, like all other German work, will bear no comparison with the Netherland engraving, either in refinement, vivacity, or skill. The other block-books, many of which are in themselves interesting and curious, do not elucidate the history of the art, and therefore need not be discussed. It is sufficient to say that they are less valuable than those which have been described, and far ruder in design and execution. Some of them throw light upon the time. The _Ars Memorandi_, a series of designs meant to assist the memory in recalling the chapters of the Apocalypse, is a very curious monument of an age when such a device was useful; and the _Ars Moriendi_, or Art of Dying, in which were depicted frightful and eager devils about a dying man’s couch, is a book which may stir our laughter, but was full of a different meaning for the poor sinner to whose bedside the pious monks carried it to bring him to repentance, by showing him designs of such horrible suggestion, enforced, no doubt, by exhortations hardly more humane. These books were all reproduced many times. This Art of Dying, for example, appeared in Latin, Flemish, German, Italian, French, and English, with similar designs, although there were variations in the text. Once popular, they have long since lost their attraction; few care for the ideas or the pictures preserved in them; the bibliophile collects them, because they are rare, costly, and curious; the scholar consults them, because they reveal the unprofitableness of mediæval thought, the needs and characteristics of the class that could prize them, the poverty of the civilization of which they are the monuments, and because they disclose glimpses of actual human life as it then was, with its humors, its burdens, and its imaginations. The world has forgotten them; but they hold in the history of civilization an honorable place, for by means of them wood-engraving led the way to the invention of printing, and thereby performed its greatest service to mankind.
