The dissertation identifies and examines objects of visual culture that shaped socio-legal dynamics in the German-speaking world between c. 1250 and c. 1500. It thematizes the role of tangible objects, artworks, and monuments in establishing legal authority during a period marked by rapid innovation and change in the legal sphere. Drawing on a selection of case studies, the dissertation argues that artifacts and monuments across media assumed active agency in sustaining jurisdictional claims by both territorial lords and municipalities. By showing how law-making depended on material and visual culture, the analysis challenges the prevailing paradigm in accounts of European legal history, which views law primarily as a textual or oral practice, and shows that this approach produces an incomplete understanding of a formative chapter in the history of European law. Through the analysis of primary textual sources, such as vernacular legal codes, the study excavates overlooked emic terminologies and concepts of art, images, and image-making. The prism gained in this part of the study paves the way for understanding how illuminated legal manuscripts, insignia, court furnishings, monuments of punishment, and the urban landscape, among others, were constructed and perceived as meaningful images, which could be strategically employed to shape new legal orders.
