This paper examines some of the Christian allusions in Beowulf. While some of these may be interpolations, the reference to Cain and Abel seems well-intergrated into the poem. On the other hand, the references to a divine flood appear on closer inspection to be grounded in Indo-European rather than Christian myth. I conclude that Beowulf is essentially a ‘Germanic’ story representing a pre-Christian world-view and that the integration of the ‘Cain and Abel’ mythologem into the story does not imply a large-scale adoption of Christian ideas.
