In these statements all is supposition and contradiction. That which is certain--and the dates are there to prove it--is the enormous progress in the productions of Peter Schoeffer. In 1459 he published his third book, Durand's _Rationale Divinorum Officiorum_, in folio. As in the Psalter, Schoeffer employed initial letters printed in red, which the rival workshop could not do in the _Catholicon_, the rubrics of which are painted by hand, as in manuscripts. In time he put forth a second edition of the Psalter, always with Fust's name joined to his own. A great number of types were broken at the beginning, but he dreamed of doing yet better. In 1460 he gave the _Constitutiones_ of Pope Clement V., with a gloss and commentaries by John André; here was the first example of a process much employed in manuscripts, but of which the typographical composition was very difficult. Again, in 1462 a new Latin Bible issued from their workshops in two folio volumes. It is the first dated edition. The first volume has two hundred and forty-two folios in double columns, the second two hundred and thirty-nine. It commences with an epistle of St. Jerome, and on the last leaf of the second volume is the colophon on the preceding page. This book, one of the first worthy of the name, and which is called by preference the Mayence Bible, appeared in one of the most troubled epochs that the episcopal city had had to go through. Subject to its archbishops, who were at the head of all the lay lords and fighting men, the city found itself in 1462 the prey of two prelates of equal title who refused to give way to one another: Thierry of Isembourg and Adolph of Nassau-Wiesbaden. Adolph surprised Mayence on the 27th October, 1462, pursuing his adversary, who scaled the walls with a rope to escape quicker, and the city was sacked and pillaged from its foundations. In the middle of this turmoil, what became of the obscure persons who were then the printers of the Bible? Doubtless their insignificance saved them from disaster, but as it was long before peace was re-established, and the entire edition of their last volume could not be kept back, we incline to believe that they were for a time going about the country as itinerant booksellers. Paris was to them a well-indicated point of travel--Paris, toward which all German commerce tended. The university where Peter Schoeffer was instructed in letters, and that truly passed for the first in Europe, appeared to them a market of the first order. If we may believe Walchius (_Decas fabularum generis humani_: Strasbourg, 1609, 4to, p. 181), John Fust himself went to that city, where he put books on sale from sixty crowns a copy, then fifty, then forty, according to the prevailing system in matters of discount. Fust was above all things a merchant; he led it to be believed that he had the marvellous establishment of a copyist beyond the Rhine, and he had disposed of many copies, when the corporate scribes of the university,
