Characters of arthurian legend
Gwion
The son of Gwreang who was left by Ceridwen to stir her cauldron. Drops from it landed on his finger which he sucked and at once understood everything that had happened or was to happen. He fled to avoid Ceridwen, both pursuer and pursued changing into different shapes. Gwion eventually changed himself into a grain of wheat and she changed herself into a hen and swallowed him. She became pregnant with him and bore him as Taliesin. All this may represent an initiatory process, as C. Matthews suggests.
