The genuineness of the inscriptions is, however, confirmed by other evidence which no mere conjecture can invalidate. On the last leaf of this Bible there is a memorandum written by Berthold de Steyna, vicar of the parochial church of “Ville-Ostein,”[III-45] to the sacrist of which the Bible belonged. The sum of this memorandum is that on St. George’s day [23d April] 1457 there was chaunted, for the first time by the said Berthold, the mass of the holy sacrament. In the Carthusian monastery without the walls of Mentz, Schwartz[III-46] says that he saw a copy of this edition, the last leaves of which were torn out; but that in an old catalogue he perceived an entry stating that this Bible was presented to the monastery by Gutemberg and Faust. If the memorandum in the catalogue could be relied on as genuine, it would appear that this Bible had been completed before the dissolution of Gutemberg and Faust’s partnership in November 1455. [Footnote III-45: Oberlin says that “Ville-Ostein” lies near Erfurth, and is in the diocese of Mentz.] [Footnote III-46: Index librorum sub incunabula typograph. impressorum. 1739; cited by Fischer, Typograph. Seltenheit. S. 21, 3te. Lieferung.] Although not a single work has been discovered with Gutemberg’s imprint, yet there cannot be a doubt of his having established a press of his own, and printed books at Mentz after the partnership between him and Faust had been dissolved. In the chronicle printed by Philip de Lignamine at Rome in 1474, it is expressly stated, under the year 1458, that there were then two printers at Mentz skilful in printing on parchment with metal types. The name of one was _Cutemberg_, and the other Faust; and it was known that each of them could print three hundred sheets in a day.[III-47] On St. Margaret’s day, 20th July, 1459, Gutemberg, in conjunction with his brother Friele and his cousins John, Friele, and Pederman, executed a deed in favour of the convent of St. Clara at Mentz, in which his sister Hebele was a nun. In this document, which is preserved among the archives of the university of Mentz, there occurs a passage, “which makes it as clear,” says Fischer, who gives the deed entire, “as the finest May-day noon, that Gutemberg had not only printed books at that time, but that he intended to print more.” The passage alluded to is to the following effect: “And with respect to the books which I, the above-named John, have given the library of the said convent, they shall remain for ever in the said library; and I, the above-named John, will furthermore give to the library of the said convent all such books required for pious uses and the service of God,--whether for reading or singing, or for use according to the rules of the order,--as I, the above-named John, have printed or shall hereafter print.”[III-48]
