This volume investigates the historical development and cultural significance of the cult of St. Swithun, a 9th-century bishop of Winchester, through a comprehensive analysis of primary source texts. Michael Lapidge, a distinguished scholar of Anglo-Saxon literature and history, utilizes decades of research to provide definitive editions of the hagiographical and liturgical texts associated with the saint. By examining these documents, the author reconstructs the evolution of Swithun's veneration and its broader implications for understanding the religious and political landscape of medieval England and Europe.

Experts and academic reviewers recognize this work as a foundational and definitive resource for the study of Anglo-Saxon hagiography. Scholars frequently highlight the rigorous editorial standards and the clarity Lapidge brings to complex, multi-layered medieval source material.
