Ceridwen and Gwion (Gwiawn) Bach’s Transformation.
But a striking instance of rapid transition from one form to another is given in the Mabinogion. The fable of Ceridwen’s cauldron is as follows:—
“Ceridwen was the wife of Tegid Voel. They had a son named Morvran, and a daughter named Creirwy, and she was the most beautiful girl in the world, and they had another son named Avagddu, the ugliest man in the world. Ceridwen, seeing that he should not be received amongst gentlemen because of his ugliness, unless he should be possessed of some excellent knowledge or strength . . . . ordered a cauldron to be boiled of knowledge and inspiration for her son. The cauldron was to be boiled unceasingly for one year and a day until there should be in it three blessed drops of the spirit’s grace.
“These three drops fell on the finger of Gwion Bach of Llanfair Caereinion in Powis, whom she ordered to attend to the cauldron. The drops were so hot that Gwion Bach put his finger to his mouth; no sooner done, than he came to know all things. Now he transformed himself into a hare, and ran away from the wrath of Ceridwen. She also transformed herself into a greyhound, and went after him to the side of a river. Gwion on this jumped into the river and transformed himself into a fish. She also transformed herself into an otter-bitch, and chased him under the water until he was fain to turn himself into a bird of the air; she, as a hawk, followed him, and gave him no rest in the sky. And just as she was about to swoop upon him, and he was in fear of death, he espied a heap of winnowed wheat on the floor of a barn, and he dropped among the wheat and buried himself into one of the grains. Then she transformed herself into a high-crested black hen, and went to the wheat and scratched it with her feet, and found him and swallowed him.”
The tale of Ceridwen, whose fame was such that she can without exaggeration be styled the goddess of witches, resembles in part the chase of the witch-hare by the black dog, and probably her story gave rise to many tales of transformations.
I now come to another kind of transformation. It was believed by the aged in Wales that witches could not only turn themselves into hares, but that by incantation they could change other people into animals. My friend, the
Rev. T. Lloyd Williams, Wrexham, lodged whilst he was at Ystrad Meurig School with a Mrs. Jones, Dolfawr, who was a firm believer in “Rhibo” or Rheibo, or witching, and this lady told my friend the following tales of Betty’r Bont, a celebrated witch in those parts.
