business, and perhaps also the fatigues of his labours, may have let the new-comer know something of his experiences. One cannot know, but it is certain that, shortly after, John Fust was so fascinated by Schoeffer, so attracted by his youth and his application, that he resolved to put new capital into the business. He did more: to permanently attach him, he gave him his grand-daughter in marriage, not his daughter, as was thought until M. Auguste Bernard rectified this mistake. We have now come to 1453, the year preceding the first dated monument of printing in movable types: _the letters of indulgence_. It may be acknowledged that the sudden affection of Fust for his workman depended on some interested motive, and not at all on attraction of the heart. Had this former student of the university of Paris found the means of rapidly founding metallic types, the search for which had cost Gutenberg many sleepless nights? Had he completed it by applying to it the matrix and punch which had then and for centuries served the makers of seals and the money-coiners? Perhaps, as was most probable, the two associates had agreed, and putting their experiences together, had conquered hitherto insurmountable difficulties. The year 1454 witnessed the diffusion throughout Christendom of letters of indulgence, accorded by Pope Nicholas V., who wished to aid in funds the King of Cyprus against the Turks. These circular letters, scattered by thousands to every corner of the world, employed numerous copyists. Arrived at Mayence, the distributers found a workshop ready prepared to furnish copies in the shortest possible time. They set to work and brought together all the type they possessed, cast or engraved, to set up these famous letters. Among the impressions was that of which we give a reproduction, which belongs to the edition called that of thirty-one lines. The original was delivered for a consideration to Josse Ott von Mospach on the 31st of December, 1454. It is not without interest, for the history of the Book and of printing, to note here that these letters of indulgence, the clandestine traffic in which was largely accelerated by rapidity of production and the small cost of each copy, formed one of the causes of the religious reform of Martin Luther. They afforded a means of raising money, and were so generally resorted to that in the register of the Hotel de Ville of Paris preserved in the Archives Nationales (H 1778) it may be seen that the sheriffs requested the Pope to allow them to employ them in the reconstruction of the bridge at the Hotel de Ville.
