In this struggle of rival national claims the schools of the Low Countries are entitled to their share of glory. It is quite possible that their claims, so generally ignored towards the end of the last century, should in the present day be accounted the most valid of all; and that, in this obscure question of priority, the presumption may be in favour of the country which supplied an art closely connected with engraving with its first elements and its first examples. It would be unbecoming in every way to pretend to enter here on a detailed history of the origin of printing. The number of exhaustive works on the subject, the explanations of M. Léon de Laborde, M. Auguste Bernard, and more recently of M. Paeile, would render it a mere lesson in repetition or a too easy parade of borrowed learning. Anyhow, the discovery of printing with type is so intimately connected with the printing of engravings, and the practical methods in both are so much alike, that it is necessary to mention a few facts, and to compare a few dates. We shall therefore, under correction, reduce to the limits of a sketch the complete picture drawn by other hands. If printing be strictly understood to mean typography, or the art of transferring written matter to paper by means of movable and raised metal types, there can be no doubt that its discovery must date from the day on which there was invented at Mayence the process of casting characters in a mould previously stamped in the bottom by a steel die bearing the type to be reproduced. Gutenberg, with whom the idea of this decisive improvement originated, is in this sense the earliest printer. His "Letters of Indulgence" of 1454 and his "Bible" are the oldest examples of the art with which he is for ever associated. In a general sense, however, and in a wider meaning of the word, it may be said that printing was known before Gutenberg's time, or at least before he published his typographical masterpieces. People previously knew both how to print broadsides from characters cut on a single block, and how to vary the arrangement of the text by using, in place of an immovable row of letters, characters existing as separate types, and capable of various combinations. On this point we must trust to the testimony of one of Gutenberg's workmen, Ulrich Zell, the first printer established in Cologne. Far from attributing to his master the absolute invention of movable type, he merely contrasts with the process known and practised in the Low Countries before the second half of the fifteenth century "the far more delicate process" of cast type "that was discovered later." And Ulrich Zell adds, "the first step towards this invention was taken in 1440 in the printing of the copies of Donatus,[5] which were printed before this time in Holland (_ab illis atque ex illis_)."
