Set in a primal past, the Mabinogi bridges many genres; it is part pre-Christian myth, part fairytale, part guide to how nobles should act, and part dramatization of political and social issues. This edition of what has become a canonical text provides a highly engaging new translation of the work, an informative introduction, and a set of background contextual materials that help place the Mabinogi in the context of medieval Welsh history and culture.
