This indifference or want of perception seems inexcusable, but it was not altogether without cause. The readers of that time were somewhat familiar with printed impressions in the form of block-books, and the _Bible of 42 lines_ may have seemed to them but a block-book of larger size and of higher order. Knowing that engraving, ink, paper, and impression upon surfaces in relief, were used in both processes, the ordinary book-buyer could have inferred that type-printing was the natural outgrowth of the older and well-known art of block-printing. According to this view, Gutenberg invented little or nothing; he did but little more than combine some old and well-known processes; he distinguished himself more by the great size of his books than by the novelty or merit [p445] of his process. It is but proper to expose this sophistry, for it is perpetuated to this day in several books on typography. This grave error did not originate with the first printers, who knew the full difference between type and block-printing. They knew that Gutenberg was indebted to the earlier block-printers for a great deal of his knowledge, but they knew as well that his system of printing was a great and an original invention, for they clearly understood, what the ordinary book-reader did not, the value of its characteristic feature. And here it may be repeated, for the error is common and it is necessary to be emphatic, that the merit of Gutenberg as an inventor is not based upon his supposed discovery of the advantages of movable types, but upon the system by which he made the movable types. All the printers of that period recognized the fact that Gutenberg’s method of making the types, or the type-mould, with its connections, was the proper basis or starting-point of the invention. Schœffer, who first printed a notice of the new art, speaks of it as the “masterly invention of printing and also of type-making,” implying that the art of printing was inseparably connected with that of type-making. John Gutenberg, in the _Catholicon_, has not a word to say about isolated types, nor about a combination of types: the admiration which he invokes for the masterly invention should, in his view of the matter, be bestowed on its system of making the types, or on the “admirable proportion, connection and harmony of the punches and matrices.” Gutenberg made no effort to secure for himself his rightful honors as the inventor of printing, but his friends who knew the nature and value of his services were not neglectful. We have abundant evidence that Gutenberg was the man, and Mentz the place, where printing was invented. Trithemius, from information furnished by Peter Schœffer, said, in a book written before 1490, “About this time (1450), the admirable and then unheard-of art of composing and printing books, by means of types, was conceived and invented at Mentz, by a citizen of Mentz, named John Gutenberg.” [p446]
