Crimthann Nia Náir (nephew of Nár), son ofLugaid Riab nDerg, was, according to medieval Irish legend and historical tradition, aHigh King of Ireland. Lugaid is said to have fathered him on his own mother,Clothru, daughter ofEochu Feidlech.[1] Clothru was thus both his mother and his grandmother.
TheLebor Gabála Érenn says he overthrew the High KingConchobar Abradruad, but does not say he became High King himself - Conchobar was succeeded byCairbre Cinnchait.[2]Geoffrey Keating[3] and theAnnals of the Four Masters[4] agree that Crimthann succeeded Conchobar as High King and ruled for sixteen years. He is said to have gone on a voyage with his aunt Nár, a fairy woman, for a month and a fortnight, and returned with treasures including a gilded chariot, a goldenfidchell board, a gold-embroidered cloak, a sword inlaid with gold serpents, asilver-embossedshield, aspear and asling which never missed their mark, and two greyhounds with a silver chain between them. Soon after he returned he fell from his horse and died atHowth. Keating says he was succeeded by his sonFeradach Finnfechtnach, theAnnals of the Four Masters by Cairbre Cinnchait.
TheLebor Gabála places him in the reign of theRoman emperorVespasian (AD 69–79). The chronology of Keating'sForas Feasa ar Éirinn dates his reign to 12 BC – AD 5, that of theAnnals of the Four Masters to 8 BC – AD 9.
