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. It is impossible to assign any date for the commencement of the thirty-six line Bible. Fust had clearly nothing to do with it, and the type may have been made and some sheets printed before the partnership for printing the forty-two line Bible was entered into in 1450. The largeness of the type and consequent lesser number of lines to the page points to an early date, for the tendency was always to increase the number of lines to the page and economise paper. Thus we find that when the first gathering of the forty-two line Bible had been printed, which has only forty lines to the page, the type was recast, so as to have the same face of letter on a smaller body; and with this type the page was made to contain forty-two lines to the page. The workmanship and the appearance of the type would also lead us to suppose that the thirty-six line Bible was printed earlier than the _Manung widder die Durcke_, which, being an ephemeral publication applicable only to the year 1455, must presumably have been printed in 1454. We can therefore probably put both Bibles earlier than 1454.
