This volume provides edited selections, together with an introduction, notes, and glossary, from the lengthy and entertaining thirteenth-century Welsh epic, Ystorya Bown o Hamtwn. A hugely popular tale, Ystorya Bown is drawn from the Anglo-Norman epic Geste de Boeve de Haumtone (which was itself translated not only into Welsh, but also Middle English, Old Norse, and Early Modern Irish), and it relays a story of heroic Christian fortitude that offers contemporary readers fascinating insights into its cultural transmission and the worldview of its audiences.
