He studied theology in Germany and Italy, became chaplain of Franz von Sickingen, and in 1519 was imprisoned by the bishop of Augsburg for preaching and writing in favor of Lutheranism, and was released only on the interposition of the queen of Denmark. He passed several years in Wittenberg as a preacher and teacher, and in assisting in Luther's translation of the Bible. His publications against the Interim, Christ-liches Bedenken auf das Interim and Das In-terim iliuminirt (1548-'9), caused the emperor to otter a high price for his capture.
