Culhwch and Olwen

Culhwch and Olwen (Welsh:Culhwch ac Olwen) is a Welsh tale that survives in only two manuscripts about a hero connected with Arthur and his warriors: a complete version in the Red Book of Hergest, ca. 1400, and a fragmented version in the White Book of Rhydderch, ca. 1325. It is the longest of the surviving Welsh prose tales. Certain linguistic evidence indicates it took its present form by the 11th century, making it perhaps the earliest Arthurian tale and one of Wales' earliest extant prose texts. The title is a later invention and does not occur in early manuscripts.
