The study deals with the iconoclastic argumentation of Leo Jud at the Second Zurich Disputation in 1523. It focuses mainly on Jud's interpretation of idolatry: it analyses the arguments, traces the causes and theological context of Jud's identification of the biblical critique of idolatry with the critique of images, in other words, the identification of the image and the idol.
The study also demonstrates the influence and defines the contribution of humanism to the iconoclastic argument in the Zurich Reformation.
