Goddess Danu is considered the most ancient of all Celtic Deities. Her name means knowledge, wisdom, teacher, wealth and abundance. She is also known as Dana and as her Welsh equivalent, Don.Some references have her as so ancient that she is both goddess and god and refer to Danu as an all-encompassing Divine Source. This multi-faceted aspect of the Divine Feminine is experienced as the air we breathe, as the river that nourishes all of life, as the bounty and abundance of earth and as the cosmic energy of universal wisdom.
