Research Statement

My current project (Crafting Knowledge in the Early Medieval West: Glosses, Learning and Culture, circa 800-1050) investigates glosses for insight into crafting knowledge in the Carolingian age. It examines glosses on Virgil and the Psalms. I am also co-organising a public exhibition at the McClay Library entitled Ciphers, Codes and Notes: Crafting Knowledge in the Medieval and Modern Worlds, which comprises panels containing reproductions of medieval manuscripts with glosses, diagrams, illuminations, ciphers and mystic writing. These sit alongside modern examples of notetaking and debate. The modern examples are drawn from the works of literary figures connected with Belfast (C.S. Lewis, Seamus Heaney and Helen Waddell), figures whose work was deeply indebted to the medieval past.
