organizing power needed to push through this heavy piece of work in the way described, it is difficult to perceive any reason why the capitalist Fust should have quarrelled with him, or to imagine how Gutenberg exposed himself to such an action as that which Fust successfully carried against him. On the supposition that the Bible was completed in or soon after 1453 the difficulty becomes almost insuperable, for it is inconceivable that if Gutenberg had produced the book within a few months of receiving his second loan from Fust he should not, by the autumn of 1455, have paid his creditor a single guilder, either for principal or interest. After his quarrel with Fust, Gutenberg apparently had dealings with two other men, with Albrecht Pfister who is found in possession of a later casting of the heavier fount of type in which the Astrological Calendar attributed to 1448 had been printed, and with a Dr. Homery. He ended his days as a pensioner at the court of the Archbishop of Mainz, while Fust, with the aid of Peter Schoeffer, whom he made his son-in-law, developed a great business. The inventor who lacks organizing power and whose invention never thrives till it has passed into other hands is no unfamiliar figure, and such a conception of Gutenberg perhaps accords better with the known facts of his career than that of a living incarnation of heroism and business ability such as his German eulogists love to depict. According to a theory developed by the present writer in an article in _The Library_ for January, 1907 (Second Series, Vol. VIII), though no originality is claimed for it, the key to the situation lies in the assertion[21] made on behalf of Peter Schoeffer that his skill in engraving had enabled him to attain results denied to the two Johns, Johann Gutenberg and Johann Fust.
