bishop and abbot. Born in Galicia of a noble family, he seems to have been consecrated bishop of Mondonedo (Dumium) at an early age. He founded Celanova abbey in 942, becoming a monk there and in 959 its abbot. Called on to administer the see of Compostela (960–7), he is said to have repelled in battle both Northmen and Saracens. He founded other abbeys, insisting on the Rule of St Benedict like other reformers of his time. He died at Celanova with a widespread reputation for wisdom. In 1195 after the usual enquiry into his life and numerous miracles he was canonized. Feast: 1 March; translation, 1 November (recalling the event in 1601).
