Diarmaid of Armagh (diedc. 852) was Abbot and bishop ofArmagh.
In the medieval Irish church, the abbot of Armagh also served as bishop. In 834, Diarmait was named Bishop to succeed Eógan Mainistrech mac Ainbthig.[1]
He was driven from his see by the usurper Foraunan in 835.[2] However, he claimed his rights and collected hiscess inConnacht, in 836.[3] He brought with him theBachal Isu (the reputed staff of Jesus), theBook of Armagh, andSt. Patrick's Bell. The first two were considered important symbols of the office and authority of the Bishop of Armagh.[4] With the support ofFedelmid mac Crimthainn, Diarmaid was installed at Armagh in 839, though the see continued to be contested.
During his bishopric, theScandinavian rovers underTurgesius seizedArmagh in 841 and leveled the churches.[3]
By 848 Diarmaid was in sole control. In 851 he attended the meeting betweenMáel Sechnaill mac Máele Ruanaid andMatudán mac Muiredaig where Máel Sechnaill was acknowledged as High King by the men of Ulster.[1]
TheAnnals of Ulster describe him as one of "the wisest of the doctors of Europe".[5] He is also known as Saint Dermot, and hisfeast is celebrated on 24 April.[2]
