FROM PARIS ET VIENNE. (PARIS, JEHAN TREPEREL, C. 1495.)] [Sidenote: THE MAINZ PSALTER.] Another early printed book is the Mainz Psalter. It is printed on vellum, and comes from the press of Fust and Schoeffer in 1457. It is remarkable not only as the first printed psalter and as the first book printed with a date, but also as being the first example of printing in colours. The initial letter B is the result of this method, and it affords a wonderful instance of true register. The blue of the letter fitted cleanly into the red of the surrounding ornament with a precision which puzzles our modern printers, and it is difficult to understand how such perfection could have been attained. Mr. Emery Walker has suggested to me that the blue letter itself might have been cut out, inked, and dropped in from the back of the red block when that was in the press, and so the two colours printed together. If this could be done with sufficient precision, it would certainly account for the exactitude of the register. Apart from this interesting technical question, however, the page is a very beautiful one, and the initial, with its solid shape of figured blue, inclosed in the delicate red pen-like tracery climbing up and down the margin, is a charming piece of page decoration. The original may be seen in one of the cases in the King's Library, British Museum. We have here an instance of the printer aiming at directly imitating and supplanting by his craft the art of the calligrapher and illuminator, and with such a beauty and perfection of workmanship as must have astonished them and given them far more reason to regard the printer as a dangerous rival than had (as it is said) the early wood engravers, who were unwilling to help the printer by their art for fear his craft would injure their own, which seems somewhat extraordinary considering how closely allied both wood engraver and printer have been ever since. The example of the Mainz Psalter does not seem to have been much followed, and as regards the application of colour, it was as a rule left as a matter of course to be added by the miniaturist, who evidently declined as an artist after he had got into the way of having his designs in outline provided for him ready-made by the printer; or, rather, perhaps the accomplished miniature printer, having carried his art as applied to books about as far as it would go, became absorbed as a painter of independent pictures, and the printing of books fell into inferior hands. There can be no doubt that the devices and decorations of the early printers were intended to be coloured in emulation of illuminated and miniatured MSS., and were regarded, in fact, as the pen outlines of the illuminator, only complete when filled in with colours and gold. It appears to have been only by degrees that the rich and vigorous lines of the woodcut, as well as the black and white effect, became admired for their own sake--so slowly moves the world!
