The Corona Borealis (Northern Starcrown) is named Caer Arianrhod in Welsh
- the self-same constellation which is associated with Ariadne, a Greek resonance of Arianrhod. It was thought as the palace of Arianhrod, while she herself was the moon.

She is often represented by silver, wheels, and a sheaf of wheat.
Caer Arianrhod is the circumpolar stars, to which souls withdraw between incarnations; she is thus a Goddess of reincarnation.

Among the Celts of Wales, She was a Goddess of Childbirth, the Moon, Fertility and Fate. She derives Her name from the Milky Way and/or the zodiac and the Moon."
