1543. “The Summer Postills,” with a series of sermons on the Epistles. 1545. A pamphlet entitled “The Popedom at Rome Instituted by the Devil.” 1545. Cranach’s Caricatures against Popedom, with brief verses on texts by Luther. 1545. A revised edition of his collected Latin writings. All the above were printed at Wittenberg. The greater number of the pamphlets were issued at once in two editions, one Latin and one German. One of the more important of the earlier pamphlets or _Flugschriften_ of Luther was the _Address to the Nobles of Germany_, which was printed in August, 1520, and of which five thousand copies were sold in five days. Of the pamphlet containing his controversial address against Eck, printed in 1518, fourteen hundred copies were sold in two days at the Frankfort Fair. The popular interest excited by the writings of Luther and his associates brought about a great change in the trade of the book-shops. Editions of the Fathers and of the lives of the Saints were pushed to one side from the counters or the book-shelves, or were stored away in the warehouses, and even the classics were neglected. All the demand was for the writings of the Reformers. The replies of the defenders of the Church found for some years a comparatively slow sale, as the sympathies of the larger book-publishing centres and of the public reached by them were largely with the Protestants. Some few of the leading publishers, including the two most important in Germany, Froben of Basel and Koberger of Nuremberg, remained, however, in the orthodox fold, and Froben, possibly at the instance of Erasmus, gave up printing the writings of Luther.
