Between 1529 and 1670, Protestants published around 55 commentaries on the Ethics and around 15 on the Politics, several of these in numerous editions. In academies and universities in Lutheran and Reformed territories throughout the Reformation and post-Reformation era, the exposition of these works continued to form the backbone of moral and political education. This tradition has, however, largely flown under the radar and is now for the first time presented in a comprehensive way. Offering a discussion of the medieval context and debt to Renaissance Aristotelianism, Svensson maps the relationships between these commentaries and their authors, presenting their shared understanding of practical philosophy in its relation to the Christian faith and offering in-depth discussions of key ethical and political concepts.
