The transformation from Cauldron to Grail is a theme that occurs throughout Celtic Mythology – from the Cauldrons of the Dagda and Cerridwen to the Holy Grail of King Arthur. In one part of the Mabinogion, which is the cycle of myths found in Welsh legend, Cerridwen brews up a potion in her magical cauldron to give to her son Afagddu (Morfran). She puts young Gwion in charge of guarding the cauldron, but three drops of the brew fall upon his finger, blessing him with the knowledge held within. Cerridwen pursues Gwion through a cycle of seasons until, in the form of a hen, she swallows Gwion, disguised as an ear of corn. Nine months later, she gives birth to Taliesin, the greatest of all the Welsh poets.
The Cauldron of Knowledge
Cerridwen’s magical cauldron held a potion that granted knowledge and inspiration — however, it had to be brewed for a year and a day to reach its potency. Because of her wisdom, Cerridwen is often granted the status of Crone, which in turn equates her with the darker aspect of the Triple Goddess (as envisaged in modern paganism). As a goddess of the Underworld, Cerridwen is often symbolized by a white sow, which represents both her fecundity and fertility and her strength as a mother. She is both the Mother and the Crone; many modern Pagans honour Cerridwen for her close association to the full moon.
