This study examines Exeter riddles, Anglo-Saxon biblical poems (Exodus, Andreas, Judith) and Beowulf in order to uncover the poetics of spolia, an imaginative use of recycled fictional artefacts to create sites of metatextual reflection. Old English poetry famously lacks an explicit ars poetica. This book argues that attention to particularly charged moments within texts - especially those concerned with translation, transformation and the layering of various pasts - yields a previously unrecognised means for theorising Anglo-Saxon poetic creativity. Borrowed objects and the art of poetry works at the intersections of materiality and poetics, balancing insights from thing theory and related approaches with close readings of passages from Old English texts.
