The authoritative works on Canonical Law were issued from the Koberger Press, together with the series of Papal Decretals of Gregory IX., Boniface VIII., and Clement V. A much smaller measure of attention was given by him to classic writers, but his list included an edition of _Selections from the Teachings of Plato_, prepared by Alkinous, and the _Introduction to Aristotle_ of Porphyry. A work which has retained a longer vitality than any of the writings of the above formidable series of scholars is the collection of monkish tales, probably compiled in the thirteenth century, and known as the _Gesta Romanorum_, the first printed edition of which was issued by Koberger in 1494. In the year 1518 (that is, five years after the death of Anthoni), there was published from the Koberger Press the _Germania_ of Franciscus Irenicus, which included a special chapter on Nuremberg, contributed by Conrad Celtes. Hase speaks of this as the first noteworthy attempt to present German national history from a popular and patriotic standpoint. The catalogues of nearly all of the publishers whose work was done within the half century succeeding Gutenberg were devoted to what would to-day be described as “heavy” literature. The most noteworthy exception to this statement is the list of publications issued by Caxton in London, between 1476 and 1492, a list which included hardly any “solid” books. The long lists of folios of scholastic writings give to the student of to-day the impression that these first publishers felt a very serious responsibility indeed in connection with the use of this “God-given art” of printing, and would have considered the use of the printing-press for frivolous literature as a kind of breach of trust. This description would, however, apply with exceptional force to the undertakings of the first Koberger, whose name appears to have been associated with no work more trifling than the famous _Gesta Romanorum_, which, while indeed to be described as fiction, was fiction of a very pious character and purpose. The catalogue of Koberger constituted, in fact, a very good representation of the foundations of scholarly Catholicism. The Catholic teachers, who rested their contention for the supremacy of the Roman Church upon history and tradition as interpreted for fifteen centuries by the scholars of the Church, depended for the material of their teachings upon such folios as those produced by Koberger. Weighty as were these folios, and assured as appeared to be the foundations upon which the great structure of ecclesiasticism had been raised, their instruction was undermined, and their authority, for a large portion at least of the community, was overthrown a little later by the influence of the widely circulated pamphlets and sheets, the _Flugschriften_, which brought to the people the teachings of the Reformers.
