Irial Fáid ("the prophet"),[1] the youngest son of Érimón by his wife Tea, according to medieval Irish legends and historical traditions, became High King of Ireland after killing Ér, Orba, Ferón and Fergna, sons of Éber Finn, in the Battle of Cul Martha, in revenge for their killing of his brothers Luigne and Laigne.
He cleared twelve plains, dug seven royal forts, and fought four battles against the Fomorians.
Having ruled for ten years, he died at Mag Muaide, and was succeeded by his son Ethriel.
The Lebor Gabála Érenn places his death during the reign of Tautanes in Assyria (1191–1182 BC according to Jerome's Chronicon).
