Zapf, to whom Fischer’s letter is addressed, had previously communicated to Oberlin his opinion that the types of the Catholicon were the same as those of an _Augustinus de Vita Christiana_, 4to, without date or printer’s name, but having at the end the arms of Faust and Scheffer. In his account, printed at Nuremberg, 1803, of an early edition of “Joannis de Turre-cremata explanatio in Psalterium,” he acknowledged that he was mistaken; thus agreeing with Schwartz, Meerman, Panzer, and Fischer, that no book known to be printed by Faust and Scheffer is printed with the same types as the Catholicon and the Vocabulary. Although there can be little doubt of the Catholicon and the Elfeld Vocabulary being printed with the same types, and of the former being printed by Gutemberg, yet it is far from certain that Bechtermuntze inherited Gutemberg’s printing materials, even though he might be a relation. It is as likely that Gutemberg might sell to the brothers a portion of his materials and still retain enough for himself. If they came into their possession by inheritance, which is not likely, Gutemberg must have died some months previous to 4th November, 1467, the day on which Nicholas Bechtermuntze and Wygand Spyess finished the printing of the Vocabulary. If the materials had been purchased by Bechtermuntze in Gutemberg’s lifetime, which seems to be the most reasonable supposition, Conrad Homery could have no claim upon them on account of money advanced to Gutemberg, and consequently the types and printing materials which after his death came into Homery’s possession, could not be those employed by the brothers Bechtermuntze in their establishment at Elfeld.[III-52] [Footnote III-52: The two following works, without date or printer’s name, are printed with the same types as the Catholicon, and it is doubtful whether they were printed by Gutemberg, or by other persons with his types. 1. Matthei de Cracovia tractatus, seu dialogus racionis et consciencie de sumpcione pabuli salutiferi corporis domini nostri ihesu christi. 4to. foliis 22. 2. Thome de Aquino summa de articulis fidei et ecclesie sacramentis. 4to. foliis 13. A declaration of Thierry von Isenburg, archbishop of Mayence, offering to resign in favour of his opponent, Adolphus of Nassau, printed in German and Latin in 1462, is ascribed to Gutemberg: it is of quarto size and consists of four leaves.--Oberlin, Annales de la Vie de Gutenberg.]
