Erard (Eberhard)
a Bavarian bishop, lived about 679. He was the brother of St. Hidulphus, archbishop of Treves, and assisted him in the administration of his see. He was consecrated originally bishop of Ardagh, in Ireland, but finally of Ratisbon, yet without a stationary location. He is often given the title of the Blessed, and is commemorated Jan. 8 (also January 6, February 9, April 14, and October 8). See Hoefer, Nouv. Biog. Generale, s.v.; Smith, Dict. of Christ. Biog. s.v;
