In the course of his work John Gutenberg returned to Mayence. The idea of publishing a Bible, the Book of books, had taken possession of his heart. The _Spiegelmacher_ of Strasbourg was on the road to loss. The cutting of his types had ruined him, and on his arrival in his native town, his stock in trade, transported by him, was of no great weight: some boxes of type, an inconvenient forme, and perhaps an ordinary press, a wine-maker's press, with a wooden screw. The idea of using this unwieldy instrument for the impression of his formes had already occurred to him; but would not the _frotton_ serve still better? The force of the blow from the bar would break the miserable type, the raised parts of which could not resist the repeated strokes. In this unhappy situation, Gutenberg made the acquaintance of a financier of Mayence, named Fust, who was in search of a business, and who put a sum of eleven hundred florins at his disposal to continue his experiments. Unfortunately this money disappeared, it melted away, and the results obtained were absolutely ludicrous. It is certain that John Fust did not enter on the engagement without protecting himself. From the first he bound his debtor in a contract for six per cent. interest, besides a share in the profits. In addition he stipulated repayment in case of failure. Gutenberg, improvident, as is the way of inventors, had signed away all that he possessed to procure funds. It is presumed, besides, that during the continuance of his investigations, he composed some current books with the resources at his disposal, that served a little to lighten his debts. But the printing house of the Zum Jungen at Mayence was far from shining in the world, because the association of Fust concerned itself only with the publication of a Bible, and not at all with the _Speculums_ and _Donatuses_ that were so much in vogue at this time. Besides, the money-lender made a point of pressing his debtor, and did not allow him any leisure to labour outside the projected work. About this time a third actor enters on the scene. Peter Schoeffer, of Gernsheim, a writer, introduced into the workshop of Gutenberg to design letters, benefited by the abortive experiments, and taking up the invention at its deadlock, conducted it to success. John of Tritenheim, called Trithemius, the learned abbot of Spanheim, is the person who relates these facts; but as he got his information from Schoeffer himself, too much credence must not be given to his statements. Besides, Schoeffer was not at all an ordinary artisan. If we credit a Strasbourg manuscript written by his hand in 1449, he was a student of the "most glorious university of Paris." In the workshop of Gutenberg, his industrious and inventive intellect found a fecund mine, and this caligraphist dreamt of other things than shaping letters for the use of wood engravers. Gutenberg, arrested in his career by the wants of life, the worries of
