  2. The machine behind the messageDescribe how movable type, a press, paper, and German translation changed the audience for Luther’s argument.Printing separated a local university dispute from its first venue, allowing anonymous printers and translators to multiply and redirect it.
  3. From Latin argument to public controversyTrace how editions, vernacular writing, and competing interests turned a scholarly text into a mass controversy.The Theses moved through print networks, while Luther’s accessible German prose and supporters’ commercial choices widened the movement’s reach.
