Printed at Strasbourg in 1517, Friedrich Riederer’s Spiegel der waren Rhetoric stands at the meeting point of German humanism, practical rhetoric, legal writing, and the emerging culture of vernacular instruction. First printed at Freiburg in 1493 and reissued only rarely, the work translates and adapts Cicero and other authorities for readers who needed eloquence not as ornament, but as a working skill: for speeches, letters, contracts, petitions, and documentary forms grounded in divine, imperial, and legal authority.
