Danu is one of the oldest Celtic goddess. She is represented by the earth and its abundance. Many place names in Ireland are associated with her, most notable the Paps of Anu in Kerry, which resemble the breasts of a large supine female, part of the land.
Danu is known as the ‘beantuathach’ (farmer) associating her with fertility. Rivers are also associated with her and in general, the fertility and abundance of the land.
Not many stories involving the Danu survive, but she appears is one story about Bile, the god of light and healing. Bile was represented as a sacred oak tree that was fed and nurtured by Danu resulting in the birth of Daghdha.
Danu is associated with the Tuatha Dé Danaan, the people of the goddess Danu. These were a group of people, descended from Nemed, who had been exiled from Ireland and scattered. Danu offered them her patronage allowing them to reunite, learning new magical skills and return to Ireland in a magical mist. The mist is Danu’s symbolic embrace. The Tuatha Dé Danaan are the clearest representatives in Irish myth of the powers of light and knowledge. The Tuatha Dé Danaan were associated with Craftsmanship, music, poetry and magic, as was Danu herself.
