Muimne, Luigne and Laigne, sons of ÃÂrimón by his wife Odba, were, according to medieval Irish legends and historical traditions, joint High Kings of Ireland following the death of their father. They ruled for three years, until Muimne died of plague at Cruachan, and Luigne and Laigne were killed by their cousins ÃÂr, Orba, Ferón and Fergna, sons of ÃÂber Finn, in the Battle of ÃÂrd Ladrann, leaving no heirs. The Lebor Gabála ÃÂrenn synchronises their reign with the last year of Mithraeus and the first two years of Tautanes as kings of Assyria (1192-1189 BC, according to Jerome's Chronicon). Geoffrey Keating dates their reign from 1272 to 1269 BC, the Annals of the Four Masters from 1684 to 1681 BC.
