Brónach ollamh déis a rígh
Irish bardic poem ascr. to Mac Coisi, i.e. Urard mac Coise (d. 983 x 1023), but composed well after his life-time. It laments the death of one Fergal ua Ruairc, a king whose grave at Clonmacnoise the poet is said to be visiting, and refers to the circumstances of the battle of Clontarf (1014). The king in question has been identified with Fergal ua Ruairc, king of Connacht, who died in c. 966 and is nevertheless depicted in Cogad Gáedel re Gallaib as having fought in the battle alongside Brian Bóruma.
