A translated collection of medieval Welsh tales that blends myth, folklore and early Arthurian legend, recounting courtly intrigue, heroic quests and encounters with the Otherworld; central narratives follow figures whose bargains, betrayals and feats—Pwyll’s dealings with the ruler of the Otherworld, the tragic saga of Bran and his sister, Gwydion and Math’s magic and trickery, and the far-ranging quest of Culhwch for Olwen—mix shape‑shifting, enchantment, dream‑vision and folklore into vivid stories rooted in late Celtic Britain.
