Cyfoesi Myrddin a Gwenddydd ei chwaer
form undefined
Long poem that takes the form of a dialogue or colloquy between Myrddin and his sister Gwenddydd. In response to his sister's questions, Myrddin reveals many details concerning the future of Britain; includes references to Myrddin as a wild man of the woods; Gwenddolau; battle of Arfderydd (570s, Cumbria); includes a regnal list, especially of the Maelgyning kings of Gwynedd, from Rhydderch Hael to Hywel Dda ap Cadell (d. 950) and beyond, at which point the poem becomes obscure. It has been suggested that it was probably originally composed when Hywel Dda reigned supreme over the kingdoms of the Merfynion.
