The author discusses the life and work of Ulrich Zasius (1461-1535), who is known primarily as the "restorer of Roman law" because of his desire to guide Roman law out of its methodical isolation and his support for returning to original sources. The use of original sources should be strictly guided by the needs of legal practice.
The author also describes Zasius's defence of canon law in the period starting with the German Reformation, and his opinion about baptizing Jewish chidren.
