Artuir was probably a war leader fighting Picts at the northern and eastern borders of the kingdom.
Artuir is mentioned in three medieval sources: in Adomnan's Life of St. Columba,[2] written c. 700; in the genealogical section of The History of the Men of Scotland,[3] originally compiled in the seventh century; and his death is also mentioned in the Annals of Tigernach, which date from around 1088.
Columba then predicts the deaths of Artuir, Eochaid Find, and Domangart while fighting their father's battles.
Adomnan adds " Artuir and Echoid Find were slain a little while later, in the battle of Miathi mentioned above.
Domangart was killed in a rout of battle in England", illustrating the fulfillment of Columba's prophecy.
