The Expulsion of the Dessi (Author: Unknown)
paragraph 17
Then Ethne the Dread advised her mother's kinsfolk to go to the chief counsellor of Munster, the seer-judge of Cashel, Lugaid Laigde Cosc. He by his wisdom and prudence helped them. He was judge to the Corco Laigdi. For there had been an interchange between the Corco Laigdi and the Eoganacht in Cashel (from the time of Darfine and Dercthine), to wit, whenever there was a king of the Corco Laigdi, there was a judge of the Eoganacht. Oengus, son of Nadfraich, was king at that time, and Lugaid Laigde Cosc was judge.
