Shortly after the death of Anthoni Koberger, we begin to find more frequent references in the correspondence of the publishers of Germany to compensation for original literary work. Boniface Amerbach had recommended to Froben the _Lucubrations_ of Zasius, and writes in 1518 concerning the author: “Zasius thinks that he ought to be paid for this work, and speaks of thirty florins as a proper price. I should, however, not assent to any such demand. He is anxious to get his book into print, and had said before that he should expect to be paid well if it succeeded, and should be quite ready to accept little or nothing if it failed to sell, a result which, however, he could not believe possible.”[82] In 1524, Hans Koberger arranged with Zasius, through Dr. Roth, for the publication of the _Intellectus Juris_. He first offered as honorarium fifty or sixty copies of the book. To this suggestion Zasius replied: “I must have my honorarium in hard cash.... I have had an enormous amount of labour and pains in getting this material into shape, and I ought to receive not less than fifty guldens.” This was an early instance of the very natural, though not very reasonable, expectation or requirement on the part of the author that his compensation ought to be based upon the extent of the labour given to the book, instead of upon the return that the public was willing to make for the book itself. Koberger did not come to terms for the _Intellectus Juris_, and it was finally published by Cratander, who paid for it twenty florins. Zasius does not appear, however, to have got along very well with Cratander, for we find him a little later breaking away from him with the word, “The devil take the printers [_zum Teufel mit deinen Drückern_], who never have treated me decently.”[83] Zasius appears to have had his full share of the _genus irritabile_. Some expressions in his correspondence recall the references made by Martial to his four publishers. He was a near friend of Zwingli, and a number of the letters preserved in the _Epistolæ_ were addressed to Zwingli. Zasius was in sympathy with the earlier efforts of the Reformers against the abuses that had crept into the Church, but he held with Erasmus that the duty of Christians was to reform and not to destroy or to divide the Church.
