The next document which relates to him as a printer is the lawsuit of 1455, the original transcript of which was recently found at Göttingen. This was brought against him by Fust to recover a loan of 800 guilders. In this lawsuit mention is made of two of Gutenberg’s servants, Heinrich Keffer, afterwards a printer at Nuremberg, and Bertolf von Hanau, supposed to be the same as Bertold Ruppel, the first printer at Basle. Peter Schœffer also appears as a witness. We learn from this suit that somewhere about August 1450, Fust advanced the amount of 800 guilders, and about December 1452 a like amount; but these loans were advanced in the first instance by Fust towards assisting a work of which the method was understood, and we are therefore justified in considering that by that time Gutenberg had mastered the principles of the art of printing.
The first two books printed at Mainz were the editions of the Vulgate, known from the number of lines which go to the page as the forty-two line and thirty-six line Bibles. The forty-two line edition is generally called the Mazarine Bible, because the copy which first attracted notice was found in Cardinal Mazarin’s library; and the thirty-six line edition, Pfister’s or the Bamberg Bible, because the type used in it was at one time in the possession of Albrecht Pfister of Bamberg. On the question as to which of the two editions is the earlier, there has been endless controversy; and before going farther, it will be as well to state shortly the actual data which we possess from which conclusions can be drawn.
The Paris copy of the forty-two line Bible has the rubricator’s inscription, which shows that the book was finished before the 15th August 1456.
The only exact date we know of, connected with the other Bible, is 1461, this date being written on a copy of the last leaf, also preserved in the Bibliothèque Nationale at Paris.
The types of both Bibles were in existence in 1454, for they were used in the thirty and thirty-one line letters of Indulgence printed in that year.
The type of the forty-two line Bible is clearly a product of the Gutenberg-Fust-Schœffer partnership, for it is used afterwards by Schœffer as Fust’s partner, and must therefore have been the property of Fust. Mr. Hessels, who has worked out the history of the types with extreme care and accuracy, says: ‘I have shown above that one of the initials of the thirty line Indulgence is found in 1489 in Schœffer’s office. The church type of the same Indulgence links on (in spite of the different capital P) to the anonymous forty-two line Bible of 1456. This Bible links on to the thirty-five line Donatus, which is in the same type, and has Schœffer’s name and his coloured capitals.[6] This again brings us to the Psalter, which Joh. Fust and Peter Schœffer published together on the 14th August 1457, at Mentz, their first (dated) book with their name and the capitals of the Donatus.’
[6] The colophon of this book says: ... ‘per Petrum de Gernssheym in urbe Moguntina cum suis capitalibus absque calami exaratione effigiatus;’ and Mr. Hessels translates ‘cum suis capitalibus,’ ‘with his capital letters,’ a rendering which is surely impossible.
We may safely say of the forty-two line Bible, that it could not have been begun before about August 1450 (when Gutenberg entered into partnership with Fust), and that it could not have been finished later than August 1456 (the rubricated date of the Paris copy).
As regards the thirty-six line Bible, M. Dziatzko has brought forward, after much patient study, some remarkable evidence. He proves, from an examination of the text, that the thirty-six line Bible was set up, at any rate in part, from the forty-two line Bible. One copy survives which betrays this; for the compositor has passed from the last word of leaf 7 to the first word of leaf 9. In another place he has misread the beginning of a chapter, and included the last two words of the one before, which is explained by the arrangement of the text in the forty-two line edition.
Dziatzko concludes that this latter edition was the product of the Gutenberg-Fust confederation, and that Gutenberg may have produced the thirty-six line Bible more or less pari passu, either alone or in partnership with (perhaps) Pfister. An examination of the paper used in printing the two books points to the conclusion that there were substantial means available for the production of the forty-two line Bible, while the thirty-six line seems to show many separate purchases of small amounts of different papers.
