Pwyll
Pwyll Pen Annwn is a prominent figure in Welsh mythology and literature, the lord of Dyfed, husband of Rhiannon and father of the hero Pryderi. He is the eponymous hero of Pwyll Pendefig Dyfed, the first branch of the Four Branches of the Mabinogi, and also appears briefly as a member of Arthur's court in the medieval tale Culhwch ac Olwen. Pwyll, Prince of Dyfed also carries many similarities to the Mabinogi Branwen.
Origin of Pwyll, Prince of Dyfed
This tale is one of a group found in The Mabinogion, one of the earliest known efforts to form a collection of traditional Welsh tales. Such tales, which date back to circa 1325 C.E., were originally passed from person to person and generation to generation orally. The Celtic oral tradition lasted for several centuries and is a possible reason for the abundance of errors and discrepancies found in The Mabinogion as well as other Welsh literature dating back to the fourteenth century or earlier. Professor Sioned Davies of Cardiff University explains the importance of the Celtic oral tradition, in appreciating Welsh literature, this way; "The Mabinogion were tales to be read aloud to a listening audience--the parchment was "interactive" and vocality was of its essence. Indeed, many passages can only be truly captured by the speaking voice."
