a small chapter of secular canons until 1093, when Hugh, Earl of Chester, converted it into a great Benedictine monastery, with the co-operation of St Anselm, then Prior of Bec, who sent Richard, one of his monks, to be the first abbot. A new Norman church was built by him and his successors. This monastery, though suffering loss of property both by the depredations of the Welsh and the inroads of the sea, prospered, and in the thirteenth, fourteenth, and fifteenth centuries the monks transformed their Norman church into a gothic building. Tudor period The last of the abbots of Chester was John, or Thomas, Clark, who resigned his abbey, valued at £1,003 5s. 11d. per annum, to the king at the time of the Dissolution of the Monasteries. In 1541 Henry VIII, without papal sanction, created six new episcopal sees, one of which was Chester. The archdeaconry of Chester, from the Diocese of Coventry and Lichfield, and that of Richmond, from York, were combined to form the new see, and it was laid down that the abbey church, now the cathedral, was to be served by a dean and six prebends, the former abbot becoming the first dean. At first the diocese was annexed to the Province of Canterbury, but by another Act of Parliament it was soon transferred to that of York. The first bishop was the Provincial of the Carmelites, John Bird, a doctor of divinity who had attracted the king's attention by his sermons preached against the pope's supremacy. Having already been rewarded by appointment as Bishop of Bangor, he was now translated to Chester. On the accession of Mary he was deprived as being a married man, and died as Vicar of Dunmow in 1556. Despite the origins of the diocese, it was recognised by the Roman See for the space of Queen Mary's reign. George Cotes, Master of Balliol and Fellow of Magdalen College, Oxford, and lecturer in theology, was appointed bishop by the Roman See. In 1556 he was succeeded by Cuthbert Scott, an able theologian and Vice-Chancellor of Cambridge University. On the accession of Elizabeth I he was one of the four Roman Catholic bishops chosen to defend Roman Catholic doctrine at the conference at Westminster, and immediately after this he was sent to the Tower and was deprived in 1559. Being released on bail, he contrived to escape to the Continent.
