The Blessed Rudesind was the son of a Count Gutierre da Mendenez, in Gallicia. His mother is said to have had a foretoken of the sanctity of the child that was about to be given her, whilst praying in the Church of S. Salvador on Mount Corduba. When the child was born, she desired to have him baptised in the church, but as there was no font there, one had to be brought up the hill in a cart. The cart broke down, says the popular legend, however, the font continued its journey without it. The child grew up to be a good man, and he was appointed to the bishopric of Dumium, a see which has ceased to exist. His kinsman, Sisnand, bishop of Compostella, was a scandal to the Church, "spending all his time in sports, excesses, and vanities, and paying no attention to his duties." Wherefore, at the request of the king, Sancho, and the nobles and people, Rudesind undertook the government of it, and Sancho put Sisnand in prison. During the absence of the king against the Moors [the Muslims of North Africa and Spain], the Normans invaded Gallicia, whereupon the bishop called together an army, marched against them, and drove them back to their ships, and then turned his arms against the Moors, and routed them. On the death of Sancho, Sisnand escaped from prison, attacked Rudesind on Christmas night, whilst engaged with the canons in the sacred offices, and threatened him, sword in hand, unless he resigned the see. Rudesind at once laid aside his office, and retired into a monastery, where he assumed the habit, and after some years was chosen abbot.
