Incorporating aspects of Celtic mythology, the cauldron is associated with the goddess Cerridwen. Welsh legend also tells of cauldrons that were useful to warring armies. In the second branch of the Mabinogi in the tale of Branwen, Daughter of Llŷr, the Pair Dadeni (Cauldron of Rebirth) is a magical cauldron in which dead warriors could be placed and then be returned to life, save that they lacked the power of speech. It was suspected that they lacked souls. These warriors could go back into battle until they were killed again.

In Wicca and some other forms of neopagan or pagan belief systems, the cauldron is still used in magical practices. Most often a cauldron is made of cast iron and is used to burn loose incense on a charcoal disc, to make black salt (used in banishing rituals), for mixing herbs, or to burn petitions (paper with words of power or wishes written on them). Cauldrons symbolize not only the Goddess but also represent the womb (because it holds something) and on an altar it represents earth because it is a working tool.
