The germs of the invention which, in spite of Carlyle's somewhat slighting reference, has proved itself hardly less momentous in the world's history than the conception of the idea of writing, are to be found in the stamps with which the ancients impressed patterns or names upon vases or other objects, or in the device and name-bearing seals which were in common use among the nations of antiquity. But these stamps and seals could be used only to impress some plastic material, not to make ink or other marks upon paper; and for the first example of printing, as we understand the word, we must look to China, where, it is said, as early as the sixth century, A.D., engraved wooden plates were used for the production of books. The Chinese, however, kept their invention to themselves, or at any rate it spread no further than Japan, until many years later; and although in the tenth century the knowledge of printing was carried as far as Egypt, Europeans seem to have made the discovery for themselves, quite independently of help from the East, both as regards block-printing and the use of moveable type.

In Europe, as in China, the first printing was done by means of a block, that is, a slab of wood on which the design was carved in relief, and from which, when inked, an impression could be transferred to paper or other material. This process is known as block-printing, and in Europe was principally used for the production of illustrations, the text, which came to be added later, being accessory and subordinate to the picture.

The first European block-prints are pictures of saints, roughly printed on a leaf of paper and usually rudely coloured. Heinecken, whose IdÉe general d'une Collection complette d'Estampes (1771) is still a standard work, is of opinion that pictures of this class were first executed by the old makers of playing-cards, and that the playing-cards themselves were printed from wood and not drawn separately by hand. In this case the cards should rank as the earliest examples of block-printing, or wood-engraving. Heinecken has not been alone in entertaining this opinion, but, on the other hand, there are some who consider that the portraits represent the first woodcuts, and that the early playing-cards were drawn and painted by hand.

The single-leaf portraits of saints were produced chiefly, or perhaps solely, in Germany, and examples are now rare. It is curious that most of those which have survived to the present day have been found in German religious houses, pasted inside the covers of old books, and thus shielded from the destruction to which their fragile nature rendered them liable. One specimen, which has the reputation of being the earliest extant with which a date can be connected, is the well-known St Christopher, which represents the saint carrying the child Christ over a stream, after an old legend. This specimen bears the date 1423, and was discovered pasted in the cover of a mediÆval manuscript in the monastery at Buxheim, in Swabia, and is now in the John Rylands Library at Manchester. The date, however, may be only that of the engraving of the block, and not the year of printing. A theory was put forward by Mr H.F. Holt, at the meeting of the British Archaeological Association in 1868, that this St Christopher, so far from being the earliest known specimen of printing of any sort, belonged to a period subsequent to the invention of typography, and that the date 1423 refers only to the jubilee year of the saint, and not to the execution of the print. He also held that the block-books, to which we refer below, were not the predecessors of type-printed books, as they are usually considered to be, but merely cheap substitutes for the costly works of the early printers. But these theories, though not disproved, do not receive the support of bibliographers in general.

Another early woodcut is the Brussels Print, which is in the Royal Library at Brussels. It is ostensibly dated 1418, but although this date is accepted by some, it has most probably been tampered with, and therefore the position of the print is at least doubtful. It is of Flemish origin, and represents the Virgin and Child, accompanied by SS. Barbara, Catharine, Veronica and Margaret. Other prints exist which are not dated, and it is quite possible that some of these may be older than the St Christopher, though no definite statements as to their date can be made. It is certain, however, that the art of block-printing was known in the closing years of the fourteenth century, and that it was practised thenceforward until about 1510, that is, some years after the invention of typography. In many manuscripts of the period, printed illustrations were inserted by means of blocks, either to save time, or because the scribe's skill did not extend to drawings.

These early woodcuts were the forerunners of the better known block-books, which also, according to Heinecken, were at first the work of the card-makers. Block-books consisted of prints accompanied by a descriptive or explanatory text, both text and illustration being printed from the same block. Since they were intended for the moral instruction of those whose education did not fit them for the study of more elaborate works, they generally deal with Scriptural and religious subjects. The earliest of all the block-books was the Biblia Pauperum, or “Bible of the Poor,” so called because it was designed for the edification of persons of unlearned minds and light purses, who could neither have afforded the high prices demanded for ordinary manuscript copies, nor have read such copies had they owned them. The Biblia Pauperum, however, exactly met their want. It is not so much a book to read, as a book to look at. It has a text, it is true, but the text is subordinate to the pictures.

The Biblia Pauperum is on paper, as paper was cheaper than vellum and considered quite good enough for the purpose. One side only of each leaf was printed, two pages being printed from one block, and the sheets folded once and arranged in sequence, not “quired” or “nested.” The resulting order was that of two printed pages face to face, followed by two blank pages face to face. The illustrations are of scenes from sacred history, and portraits of Biblical personages, accompanied by explanatory Latin or German texts in Gothic characters. The original designer and compiler of this favourite block-book is unknown, but he certainly worked on lines laid down by some much older author and artist, for manuscript works of similar nature existed at least as early as the beginning of the fourteenth century. The earliest known instance of a composition of the kind, however, is a series of enamels on an antependium or altar-frontal in the St Leopold Chapel at Klosterneuburg, near Vienna, which originally contained forty-five pictures dealing with Biblical subjects, arranged in the same order as in the Biblia Pauperum, and which were executed by Nicolas de Verdun, in 1181. Some attribute the inception of the Biblia Pauperum to Ansgarius, first Bishop of Hamburg, in the ninth century, others to Wernher, a German monk of the twelfth century, but it seems unlikely that the point will ever be decided. The Biblia Pauperum is usually supposed to have been first printed xylographically in Holland, and type-printed editions were issued later from Bamberg, Paris and Vienna.

To modern eyes the illustrations of this book are strange and wonderful indeed. “The designer certainly had no thought of irreverence,” says De Vinne, “but many of the designs are really ludicrous. Some of the anachronisms are: Gideon arrayed in plate-armour, with mediÆval helmet and visor and Turkish scimitar; David and Solomon in rakish, wide-brimmed hats bearing high, conical crowns; the translation of Elijah in a four-wheeled vehicle resembling the modern farmer's hay-wagon. Slouched hats, puffed doublets, light legged breeches and pointed shoes are seen in the apparel of the Israelites who are not represented as priests or soldiers. Some houses have Italian towers and some have Moorish minarets, but in none of the pictures is there an exhibition of pointed Gothic architecture.”
