of Britonia for a long time, doubtless because the great distance from Toledo made it impossible for them to assist at the councils. In 633 Metopius, Bishop of Britonia, assisted at the Fourth Council of Toledo, presided over by St Isidore of Seville. Sonna, his successor, was one of the bishops who signed at the Seventh Council of Toledo (646) and sent a representative to the Eighth Council of Toledo (16 December 653). When Britonia was invaded and destroyed by the Saracens, the bishop and priests took refuge in Asturias. In 899, during the reign of Alfonso III of Asturias, Theodesimus, Bishop of Britonia, assisted with other prelates at the consecration of the church of Santiago de Compostela. It may also be noted that, in the repartition of the parishes, the church of San Pedro de Nova was assigned as the residence of the bishops of Britonia and Orense, when they should come to assist at the councils of Oviedo. By that time, however, the See of Britonia had been translated to the town of Mondumetum and the church of St. Martin of Dumio, or Mondoñedo. The diocese has since been most generally known by this name, although the episcopal residence has again changed. After the time of St. Martin it was transferred to Villamayor de Brea, from which it derived the name of Villabriensis, and afterwards to Ribadeo, but it was nevertheless known as Mindoniense, as a document of the year 1199 bears witness. At first, its patron was St. Martin of Tours, but St. Martin of Dumio was afterwards chosen patron. The diocese of Valabria, corresponding to the diocese that had its seat at Villamayor de Brea, is included in the Catholic Church's list of titular sees.
