One of the principal poems of Ossian, in eight books, so called from the royal residence of the kings of Connaught. Cairbar had usurped the throne, having killed Cormac, a distant relative of Fingal; and Fingal raised an army to dethrone the usurper. The poem begins from this point with an invitation from Cairbar to Oscar, son of Ossian, to a banguet. Oscar accepted the invitation, but during the feast a quarrel was vamped up, in which Cairbar and Oscar fell by each other's spears. When Fingal arrived a battle ensued, in which Fillan, son of Fingal, the Achilles of the Caledonian army, and Cathmor, brother of Cairbar, the bravest of the Irish army, were both slain. Victory crowned the army of Fingal, and Ferad-Artho, the rightful heir, was restored to the throne of Connaught.
