In Irish mythology, Caitlín (Old Irish: Cethlenn, Cethleann, Ceithlenn, Ceithlionn) was the wife of Balor of the Fomorians and, by him, the mother of Ethniu. She was also a prophetess and warned Balor of his impending defeat by the Tuatha Dé Danann in the second battle of Magh Tuiredh. During that battle she wounded the Dagda with a projectile weapon. She was also known by the nickname Cethlenn of the Crooked Teeth.[1]
