Celtic mother goddess of water, earth, and according to some sources, fertility. Not much is known about Danu's original role in legend. Some believe her to be a representation of the Danube river. I often celebrate her on Imbolc and Ostara. I feel her most when I am near the river. Although the legends surrounding her are vague she has a very strong presence. She is sort of mother earth personified and she is just as beautiful and kind and volatile and harsh as the earth can be. I asked her for help one Spring when there was bad flooding in my area. I found her by looking up deities associates with rivers. The Spring I started working with her, my grandparents cottage was the only one on their road that wasn't damaged in the flood. I give her offerings every summer.
