The most common manuscripts of the time, which had hitherto been the cheapest mode of intellectual communication, were especially fitted to be reproduced by the new art; they were those illustrated abridgments of Scriptural history or doctrine, called Biblia Pauperum, or books of the poor preachers, which had long been used in popular religious instruction, in accordance with the mediæval custom of conveying religious ideas to the illiterate more quickly and vividly through pictures than was possible by the use of language alone. In the sixth century Gregory the Great had defended wall-paintings in the churches as a means of religious instruction for the ignorant population which then filled the Roman provinces. In a letter to the Bishop of Marseilles, who had shown indiscreet zeal in destroying the pictures of the saints, he wrote: “What writing is to those who read, that a picture is to those who have only eyes; because, however ignorant they are, they see their duty in a picture, and there, although they have not learned their letters, they read; wherefore, for the people especially, painting stands in the place of literature.”[27] In conformity with this opinion these manuscripts were composed at an early period; they were written rapidly by the scribes, and illustrated with designs made with the pen, and rudely colored by the rubricators. They served equally to take the place of the Bible among the poor clergy—for a complete manuscript of the Scriptures was far too valuable a treasure to be within their reach—and to aid the people in understanding what was told them; for, doubtless, in teaching both young and old the monks showed these pictures to explain their words, and to make a more lasting impression upon the memory of their hearers. These designs, it is worth while to point out, exhibit the immobility of mind in the mediæval communities, guided, as they were, almost wholly by custom and tradition; the designs were not original, but were copied from the artistic representations in the principal churches, where the common people may have seen them, when upon a pilgrimage or at other times, carved among the bass-reliefs or glowing in the bright colors of the painted windows. They were copied without change, the scenes were conceived in the same manner, the characters were represented after the same conventional type, even in the details there was slight variation; and as the decorative arts in the churches were subordinated to architecture, these designs not infrequently bear the stamp of their original purpose, and are marked by the characteristics of mural art. They were copied, too, not only by the scribes from early representations, but they were reproduced by the great masters of the Renaissance from the manuscripts and block-books themselves; Dürer, Quentin Matzys, Lukas van Leyden, Martin Schön, and, in earlier times, Taddeo Gaddi and Orcagna, took their conceptions from these sources.

Of the block-books which reproduced these and similar manuscripts several have been preserved, and some of them have been reproduced in fac-simile, and minutely described. Among the most important of these, the Biblia Pauperum,[28] or Poor Preachers’ Bible, of which copies of several editions exist, deserves to be first mentioned. It is a small folio, containing forty pages, printed upon one side only, with the pale brownish ink used in most early prints, and by means of a rubber. The pages are arranged so that they can be pasted back to back; each page is divided into five compartments, separated by the pillars and mouldings of an architectural design, which immediately recall the divisions of a church window; in the centre is depicted some scene (Fig. 5) from the Gospels, and on either side are placed scenes from the Old Testament history illustrative or typical of that commemorated in the central design; both above and below are two half-length representations of holy men. Various texts are interspersed in the field, and Latin verses are written below the central compartments. It will be seen that the designs not only served to illustrate the preacher’s lesson, but suggested his subject, and indicated and directed the course of his sermon: they taught him before they taught the people.

But, before commenting on this volume, it will be useful to describe first the much more interesting and more famous Speculum Humanæ Salvationis,[29] or Mirror of Human Salvation, an examination of which will throw light on the history of the art. It is a small folio, and contains sixty-three pages, printed upon one side, of which fifty-eight are surmounted by two designs enclosed in an architectural border, which are illustrative or symbolical of the life of Christ or of the Virgin; the designs (Fig. 6) are printed in pale ink by means of a rubber. The text is not engraved on the block or placed in the field of the cut, but is printed from movable metallic type in black ink with a press, and occupies the lower two-thirds of the page, in double columns. The book is, therefore, a product of the two arts of wood-engraving and typography in combination. There are four early editions known, two in Latin, and two in Dutch, all without the name of the printer, or the date or place of publication. They are printed on paper of the same manufacture, with woodcuts from the same blocks, and in the same typographical manner, excepting that one of the Latin editions contains twenty pages in which the text is printed from engraved wood-blocks in pale brownish ink, and with a rubber, like the designs. These four editions, therefore, were issued in the same country.

This curious book has been the subject of more dispute than any other of the block-books, because it offers more tangible facts to the investigator. The type is of a peculiar kind, distinctly different from that used by the early German printers, and the same in character with that used in other early books undoubtedly issued in the Low Countries. The language of the Dutch editions is the pure dialect of North Holland in the first part of the fifteenth century; the costumes, the short jackets, the high, broad-brimmed hats, sometimes with flowing ribbons, the close-fitting hose and low shoes of the men, the head-dresses and skirts of the women, are of the same period in the Netherlands, and even in the physiognomy of the faces Flemish features have been seen. The designs, too, are in the manner of the great Flemish school, renowned as the best in Europe outside Italy, which was founded by Van Eyck, the discoverer of the art of painting in oil, and which was marked by a realism altogether new and easily distinguished; the backgrounds are filled with architecture of the same time and country. The Speculum, therefore, was produced in the Low Countries; it must have been printed there before 1483, and probably was printed some time before 1454. The Biblia Pauperum has so much in common with the Speculum in the style of its art, its costumes, and its general character, that, although of earlier date, it may be unhesitatingly ascribed to the same country.
