The delays and difficulties which Gutenberg encountered in the printing of this edition were great, but no part of the work was done hastily or unadvisedly. He may not have received practical education as a book-maker, but he had the rare good sense to accept instruction from those who had. The _Bible of 42 lines_ was obviously planned by an adept in all the book-making skill of his time. It was laid out in 66 [p420] sections, for the most part of 10 leaves each. To facilitate the division of the book in parts (so that it could be bound, if necessary for the convenience of the reader, in ten thin volumes), some of the sections have but 4, some 11, and some 12 leaves. The book proper, without the summary of contents, consists of 1282 printed pages, 2 columns to the page, and, for the most part, with 42 lines to the column.[263] A wide margin was allowed for the ornamental borders, without which no book of that time was complete, and large spaces were also left in the text for the great initial letters. It was expected that the purchaser of the book would have the margins and spaces covered with the fanciful designs and bright colors of the illuminator. In some copies, this work of illumination was admirably done; in others it was badly done or entirely neglected. The rubrics were roughly made by dabbing a brush filled with red ink over a letter printed in black. On the pages of 40 lines, the summaries of chapters were printed in red ink; on other pages the summaries were written, sometimes in red and sometimes in black ink. [p421] It would seem that it was Gutenberg’s original intention to print all the summaries in red ink, and that he was obliged, for some unknown reason, to have them written in.
