Arianrod
Heroine of the fourth branch of the Welsh Mabinogi. Her name means “Silver Wheel”. She is the daughter of Dôn and the sister of Amaethon and Gwydion.
Through an incestuous relationship with Gwydion she gives birth to two sons: Dylan Eil Ton and Lleu Llaw Gyffes. She abandons the first and refuses to acknowledge the second, whom she curses. But Gwydion, through cunning, manages to counteract the curse. Arianrod is the image of the woman who rejects motherhood.
The expression Caer Arianrod, used by Welsh poets, designates the constellation Corona Borealis.
