Cethlenn

In Irish mythology, Cethlenn (Old Irish) or Cethleann (Modern Irish) 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.
