Bourdin, Maurice antipope, a native of Limousin, accompanied, in 1095, Bernard, archbishop of Toledo, who made him his archpriest, and gave to him the bishopric of Coimbra. In 1110 he succeeded St. Geraud, archbishop of Braga, and was sent by Pascal II to settle the difficulties which existed between him and the emperor Henry V. He proved false to the interests of Pascal,.who caused him to be excommunicated at the Council of Benevent. This pontiff died soon after, and Henry succeeded in electing Maurice, who took the name of Gregory VII; but his election was soon declared null, and he fell into disgrace and died in prison at Fumone, near Alatri, in 1122.
