The original Nuremberg printing of Luther's Ninety-Five Theses. "Martin Luther’s Disputatio pro declaratione virtutis indulgentiarum of 1517, commonly known as the Ninety-Five Theses, is considered the central document of the Protestant Reformation. Its complete title reads in translation: “Out of love and zeal for clarifying the truth, these items written below will be debated at Wittenberg. Reverend Father Martin Luther, Master of Arts and of Sacred Theology and an official professor at Wittenberg, will speak in their defense. He asks this in the matter: That those who are unable to be present to debate with us in speech should, though absent from the scene, treat the matter by correspondence. In the Name of Our Lord Jesus Christ. Amen.” Berlin State Library
