Cerridwen is the shapeshifting Celtic goddess of knowledge, transformation and rebirth. The Awen, cauldron of poetic inspiration, is her main symbol. In part of Welsh legend, she brews a potion to give to her son Morfran. She puts Gwion in charge of guarding the cauldron. Three drops of the brew fall upon his finger, blessing him with the knowledge held within. Cerridwen pursues him until, as a hen, she swallows him. Nine months later, she gives birth to Taliesen, the greatest of Welsh poets.
