"Die Bulla widder die Turcken", also Printed by Gutenberg, of which One Copy Survives

The Bulla Turcorum of Pope Calixtus III, announcing the conquest of Constantinople by the Ottoman Turks, and seeking funding for another crusade against the Turks, was translated into German by Heinrich Kalteisen and printed by Johannes Gutenberg in the DK type, as Die Bulla widder die Turcken.

Like the Latin edition probably published only days earlier, only one copy survives, in the Staatsbibliothek Preussischer Kulturbesitz, Berlin.
