Arianrhod (Old Welsh) combines arian (silver) and rhod (wheel). **The Welsh goddess of the silver wheel — the moon, the stars, and the spinning of fate** — whose celestial castle Caer Arianrhod is identified with the constellation Corona Borealis. **Daughter of Dôn, sister of Gwydion**, central figure of the Fourth Branch of the *Mabinogi*. **She placed three curses on her son Lleu Llaw Gyffes** — that he would have no name, no arms, and no wife of any race living — each circumvented by his uncle Gwydion's magic.
Featured in the *Mabinogion*.
Arianrhod reduces to one — the number of silver wheel of fate.
