This interdisciplinary collection sets the cultural transformation of early medieval Ireland and Anglo-Saxon England in the context of its inheritance from Late Antiquity and engagement with the wider Medieval world. Honoring the work of Jennifer O'Reilly, this exciting volume brings together new research on a range of patristic and medieval texts and visual materials. It testifies to the imaginative ways in which scholars and artists in these islands assimilated and creatively re-interpreted the Christian and Mediterranean culture they encountered through the coming of Christianity.
