Following the interest in recent years in Celtic spirituality, Paul Cavill's book looks at the impact of Christianity on the pagan Germanic peoples who invaded Britain from the 5th century onwards. Drawing on historical and archeological evidence, he paints a vivid picture of Anglo-Saxon culture and belief, contrasting this with the Celtic world view, and explaining how the powerful warrior code of the Anglo-Saxon peoples became merged with new Christian values. Quotes from Anglo-Saxon literature include the epic "Beowulf", and "The Dream of the Rood" along with Caedmon's "Hymn to Creation", a translation of Psalm 136 and numerous miracle stories.
