The battle of Cenn Abrat forms part of the story known as The Battle of Mag Mucrama and is told in §§ 10-14 of Stokes' edition (RC 13, 440). It is recorded in the Annals of Tigernach (RC 17, 10) and by the Four Masters, A.D. 186. There is, however, a longer account which appears as a separate story and is preserved in two manuscripts, The Book of Lecan (15th century) and RIA C i 2 (15th-16th centuries.) The occasion of the battle is not mentioned here, but according to the tradition of the Battle of Mag Mucrama, a dispute arose between Lugaid Mac Con and his foster brother Éogan son of Oilill Ólom, king of Munster, about a fairy musician they had found, each of them claiming the musician for himself. The king decided in favour of Éogan, and Lugaid said that it was a false judgement.
