Medieval Heresies: On A Less Trodden Path

How did "heretical" ideas travel in medieval society across linguistic, cultural and geographical boundaries, and how was such religious deviation understood? This edited volume invites readers to reconsider medieval heresies not as isolated or marginal phenomena, but as part of a dynamic and interconnected religious landscape that extended far beyond local or regional settings. Rather than approaching heresy through fixed categories or rigid typologies, the volume highlights the diversity of practices, beliefs, and intellectual traditions that shaped religious nonconformity between the seventh and the fifteenth centuries. By bringing together perspectives from different regions of Europe and the eastern Mediterranean, the book shows how ideas circulated across long distances, were adapted to local contexts, and were continually reinterpreted over time. The volume also demonstrates the value of comparative approaches in uncovering connections between seemingly distant societies and revealing patterns of cultural and religious exchange. A central concern of the volume is the lived reality of religious dissent. Attention to local practices, social environments, and historical circumstances allows for a more nuanced understanding of how heterodox beliefs emerged, functioned, and were perceived. At the same time, the book situates these local expressions within broader networks of transmission that connected Latin, Byzantine Greek, and Slavic cultural spheres. Contributors examine both textual and material evidence, from manuscripts to social practices, showing how ideas moved not only through intellectual circles but also through communities and everyday life. The contributions combine methods from history, philology, intellectual history, and comparative analysis to reassess established narratives and open new perspectives on medieval religious culture. By crossing linguistic and disciplinary boundaries, the volume challenges long-standing assumptions and demonstrates the value of interdisciplinary research. It offers readers tools to think critically about how knowledge, belief, and cultural norms are transmitted and transformed over time. By making this research openly accessible, the volume aims to reach not only specialists but also a wider readership interested in the history of religion, cultural exchange, and intellectual diversity. It offers fresh insights into how societies negotiate difference and beliefquestions that remain highly relevant today. Furthermore, the volume underscores the importance of collaborative scholarship, showing how bringing together scholars from East and West enriches understanding and fosters dialogue across historical and contemporary divides.
