The shrewd and enterprising merchant Fust, by means of whose capital Gutenberg had been able to begin his business operations, would hardly have pressed his suit against his associate, if he had not had confidence in the value of the invention. As soon as, through the decision of 1455, he came into possession of the presses, he at once put these again into operation. He found a practical superintendent or co-worker in Peter Schöffer. Schöffer was a German by birth, but had carried on work in Paris as a scribe or writer of higher class manuscripts, as illuminator, and as a manuscript-dealer. Returning to Mayence in 1454, he had entered the employ of Gutenberg as type-setter and proof-reader. Later, having married the daughter of Fust, he was taken into partnership by his father-in-law, and was able to make a satisfactory organisation and a wide development for the business of the printing-office. The first publication issued by Fust & Schöffer was a psalter printed (in Latin) on parchment, with the great missal type. The second work, undertaken, not at the risk of the printers, but at the cost of two of the Mayence monasteries, was an edition of a great choir-book. This psalter, or rather _psalterium_, is the first printed work in which the name of the printer is given and the date of the publication. It apparently proved possible to secure for this book even with the very inadequate distributing machinery that was available, a remunerative sale, as it was printed again in 1490, in 1502, in 1515, and in 1516. Among the earlier publications of Fust & Schöffer are the _Rationale Divinorum Officiorum_ of the Dominican monk Durandus, which was issued in 1459, the _Codex Constitutionum_ of Pope Clement, issued in 1460, and the _Bull_ of Emperor Frederic III. against Diether von Isenburg, printed in 1461. The most beautiful and most important production of their press was, however, the great Latin Bible issued in 1462, in two folio volumes, and which is known as the “48 line Bible.” The work of the printing-office was, as previously stated, stopped by the sacking of the city, and the two partners appear to have migrated for the time to Frankfort. In 1464, they were again in Mayence, and in that year they published the sixth book of the _Decretals_ of Pope Boniface VIII., and the _De Officiis_ of Cicero. The latter was the first of the German editions of the classics, and remained a favourite book with the German printers, being repeatedly reprinted.
