Burial of horses and horse-elements occurred throughout Europe during the first millennium AD. These burials are prevalent in northwest Europe and are perhaps more significant in Britain than previously realised. This article explores the position and value of the horse within Britain during this period and why the burials are likely to represent ritual deposition. Both horse and human-horse burials, are linked to non-Christian burial and sacrificial practices of the Iron Age and Early Medieval period and are particularly associated with Anglo- Saxon and Viking Britain. Some of the traditions appear to reflect the culture described in the Icelandic Sagas, Beowulf, and other legends and chronicles. Archaeologically, the human-horse burials are also linked with high status individuals and ‘warrior graves’, while complete-horse and horse-element burials may represent ritual feasting and/or sacrificial rites which are probably linked with fertility, luck, and the ancestors.
