Walter Map’s De nugis curialium is a strange work, comprising a series of humorous anecdotes, with some serious satire, particularly of the monastic orders. Despite the attention it has drawn in modern times, it seems not to have been widely known and is preserved only in Bodleian MS Bodl. 851.

The book’s final chapter argues that the various elements of fairy belief as we might recognise it, including belief in an underground otherworld inhabited by sometimes pygmy-sized otherworlders, the connection between fairies and fate, and the sexual aspects of fairy activity, were brought together as a direct result of the Norman Conquest. The key role played in the Conquest by Breton nobles who felt a cultural affinity with the Cornish and Welsh, combined with the Normans’ desire to escape the English past, resulted in the crafting of a new ‘British’ identity for the whole island of Great Britain by authors with a Brittonic cultural background such as Geoffrey of Monmouth, Gerald of Wales and Walter Map. These authors united elements of English and Brittonic folklore to fashion a new fairy world that was subsequently adopted as the setting for literary romances and became the background to late medieval popular belief.
