Irial Fáid ("the prophet"), 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).
Geoffrey Keating dates his reign from 1269 to 1259 BC, the
Annals of the Four Masters from 1681–1671 BC.
