(iv) In August, 1456, Heinrich Cremer, vicar of the collegiate church at Mainz, recorded his completion of the rubrication and binding of a magnificent printed Bible in two volumes, now preserved in the Bibliotheque Nationale at Paris, the type of which used to be thought identical with the larger type of the thirty-line Indulgence mentioned above, but is now considered to be only closely similar. For this last undoubted date of rubrication, August, 1456, German bibliographers have lately substituted a reference to a manuscript date, 1453, in another copy of this printed Bible, now preserved in the Buchgewerbe-Museum at Leipzig, formerly owned by a well-known German collector of the last century, Herr Klemm. While, however, this date appears to have been written at a period approximating to that of the production of the book, its relevance as evidence of the date of printing is highly disputable, more especially as there appear to be signs of erasure near it. Its owner, Herr Klemm, preserved a discreet silence as to its existence, and it is certainly not obligatory at present to accept it as valid evidence. In a work which does not pretend to the dignity of a history of printing it is impossible to discuss, or even to enumerate, the different theories as to the events of the years 1453-6, which have been formulated to account for these facts. The edition of the Bible of which Heinrich Cremer rubricated the copy now at Paris is so fine a book and so great a landmark in typographical history, that the desire to regard it as the production of the man who is credited with the invention of printing, Johann Gutenberg, easily becomes irresistible. To refuse to call it the Gutenberg Bible may, indeed, appear almost pedantic, though its old name, the "Mazarine Bible," which it gained from the accident of the copy in the Mazarine Library at Paris being the first to attract attention, still survives, and it is also known among bibliographers as the "Forty-two Line Bible," a safe uncontroversial title based on the number of lines in most of its columns. Whoever printed it appears to have been possessed of ample means and to have been a master of detail and an excellent organizer. Under the minute examination to which it has been subjected the book has yielded up some of its secrets, and we know that it was printed simultaneously on six different presses, that the body of the type was twice reduced, forty-two lines finally occupying slightly less space than the forty which had at first formed a column, that after the printing had begun it was resolved to increase the size of the edition, and that there is some reason to think that eventually a hundred and fifty copies were printed on paper and thirty on vellum,[20] and that the paper was ordered in large quantities and not in small parcels as it could be paid for. To the present writer it appears that if Gutenberg had possessed the financial means, the patience and the
