Here end the Decretals, most correctly printed in the bounteous city of Rome, queen of the whole world, by those excellent men Master Ulrich Han, a German, and Simon di Niccolo of Lucca: with the ordinary glosses of Bernard of Parma and his additions, which are found in few copies; both printed and corrected with the greatest diligence. Purchase these, book-buyer, with a light heart, for you will find such excellence in this volume that you will be right in easily reckoning other editions as worth no more than a straw.[8]

We find that the Nuremberg Chronicle is the only book which Dr. Pollard can call to mind that gives explicit information as to its illustrators, Michael Wolgemut and Wilhelm Pleydenworff; and finally we come to books where the author takes a hand, and we sometimes have a double colophon, as in the case of the Morte d'Arthur. Here we have Sir Thomas Malory's colophon, requesting the reader's prayer for his deliverance, and for the repose of his soul, and William Caxton's business-like statement as editor, printer and publisher.

The author's struggle with the printer, to obtain his own way, is no new thing, as proved by this late colophon of the musician, Johann von Cleve, affixed to his Cantiones, 1580:

As I come to the end of my task it seems worth while to inform students and amateurs of music that this collection of Motets was in the first place entrusted to Philip Ulhard, citizen and printer of Augsburg, to be printed, and that he (as often happens), being made unreasonably capricious by bodily ill-health, often did not carry out our intention, and compelled me, by leaving out some motets (which however, if life bears me company and God helps, will shortly be published), to abridge the work, and more especially as the same printer, when the work was not yet finished, came to an end of his days, and there upon the work was entrusted to Andreas Reinheckel to be completed, if anything, therefore, is found which might disturb a connoisseur, I pray musicians to bear with it with equanimity. Farewell. In the year of the Lord 1580, in the month of January.

We have noted one rhyming colophon, a mannerism much affected by Italian printers. Another fanciful custom by which the early printers called attention to their colophons was the use of eccentric arrangements of types, by which these final paragraphs appeared in the shape of wedges, funnels, diamonds, drinking glasses and the like.

The earliest known title page is in a Bull of Pius IX, printed in Mainz by Fust and Schöffer in 1463, but it was some twenty years before the custom became common. At first the title only, taking the form of a single sentence, appeared at the top of a title page, but it was not long before, either in the interests of decoration or of advertising, a simple woodcut or the device of the printer appeared below the title. In his A Treatise on Title-pages, 1902, Mr. De Vinne proposes the following ingenious explanation of the evolution of the printer's mark: "It was hoped that the distinctiveness of a peculiar device would be remembered by the book-buyer who had forgotten the name of his preferred printer.

"In the beginning the device was put at the end of the book, above or below the colophon. It was at first a small and simple design ... but the eagerness to have a device that should be striking led to its enlargement and afterward to an entire change of position. When the greater part of the last page was preoccupied by the last paragraph of the text, the device required a separate page. This led to making full-page devices and afterward to the putting of the device on the first page."

As time went on it was only natural that the remaining space at the foot of the title pages should be utilized for brief details of printing and publishing, but the transition was gradual and unsystematic. Indeed, some printers continued to use colophons alone well into the sixteenth century, and there are frequent instances during that century of books containing both title pages and colophons, the latter being a repetition, at the end of the book, of the imprint, as the few business-like lines at the foot of the title page had come to be named.

By the time that title pages were firmly established, publishing had become a separate business, and the publisher was not long in assuming the ascendency, often pushing the printer altogether into the background and appearing alone in the imprint. For a long time the printer modestly tucked in his name wherever he could, sometimes on the verso of the title page, and sometimes at the bottom of the last page, but in a formal manner, without the naive and often delightful and useful details which make the early colophons so interesting.
