modern counties of Norfolk, Suffolk and Cambridgeshire, which later were to form the diocese of Norwich. He was succeeded in turn by Thomas in 647, Brigilsus (died about 669) and Bifus. Upon the death of Bifus, in 673 Theodore, the Archbishop of Canterbury, divided the see between Dunwich and Elmham. The see of Elmham came to an end in about 870, after the East Anglian king Edmund and the bishop Humbertus were murdered by the Danes. East Anglia was ravaged, the churches and monasteries destroyed, and Christianity was only practised with difficulty. Wilred, Bishop of Dunwich seems then to have reunited the dioceses, choosing Elmham as his see. The line of his successors at Elmham then descended to Herfast, a chaplain to William the Conqueror, who removed his see to Thetford Priory and died in 1084. Herbert de Losinga obtained his appointment in 1091 by means of a simoniacal gift to King William Rufus to secure his election, but being subsequently struck with remorse went to Rome in 1094 to obtain absolution from the pope. Herbert founded a priory in Norwich in expiation for his sin and at the same time moved his see there from Thetford in 1094 under William. The See of Thetford was formed when Herfast moved the episcopal see from Elmham to Thetford in 1075. This short-lived see continued until it was moved to Norwich in 1094. The chapter of secular canons was dissolved and monks took their place. The foundation-stone of the new cathedral at Norwich was laid in 1096, in honour of the Blessed Trinity. By the time of his death in 1119, Herbert de Losinga had completed the choir, which is apsidal and encircled by a procession path, and which originally gave access to three Norman chapels. His successor, Everard, completed the long Norman nave so that the cathedral is a very early twelfth-century building, modified naturally by later additions and alterations. The chief of these is the Lady Chapel (c. 1250, destroyed by the Protestant Dean Gardiner 1573–1589); the cloisters (c. 1300), the West Window (c. 1440), the rood screen, the spire and the vault spanning the nave (c. 1450). The cathedral suffered much from iconoclasm during the Reformation and the civil wars. The Norwich diocese consisted of Norfolk and Suffolk with some parts of Cambridgeshire, being divided into four archdeaconries: Norfolk, Norwich, Suffolk, and Sudbury. At the end of the seventeenth
