The first use of the title "Emperor of the Gael" was credited to the king's amanuensis, Máel Suthain. The Annals of Ulster, under the year 1005, recorded that Brian donated 20 ounces of gold to the monastery at Armagh, where he was named Emperor, and where he declared Armagh the religious capital of Ireland.
