Lindisfarne became the base for Christian evangelism in the North of England, and also sent a successful mission to Mercia. Monks from the Irish community of Iona settled on the island. Northumbria's patron saint, Saint Cuthbert, was a monk and later abbot of the monastery, and his miracles and life are recorded by the Venerable Bede. Cuthbert later became Bishop of Lindisfarne. An anonymous life of Cuthbert written at Lindisfarne is the oldest extant piece of English historical writing. From its reference to "Aldfrith, who now reigns peacefully", it is considered to date to between 685 and 704. Cuthbert was buried here, his remains later translated to Durham Cathedral (along with the relics of Saint Eadfrith of Lindisfarne). Eadberht of Lindisfarne, the next bishop (and later saint), was buried in the place from which Cuthbert's body was exhumed earlier the same year, when the priory was abandoned in the late 9th century.
