John Chambers, who was the abbot of _Peterburgh_ before these changes commenced, conformed to the new order of things, and was retained in office by the king,--the monastery being converted into a cathedral, and the abbot into a bishop. The new establishment consisted of a Bishop, a Dean, and six canons; besides these the statutes directed that there should be six Minor Canons chosen, among other good qualifications, for their skill in singing, by whom the services in the Cathedral, were to be conducted, according to the usage of the old Cathedrals. Of these, one was to be chosen as Precentor, to whom the other Minor Canons, the Organists, Lay Clerks, and Choristers, were to be subordinate. The chancel of Thomas a Becket's Chapel, already spoken of, was then converted into a school-room, in which the Choristers, and a certain number of other boys, were to receive a classical education at the hands of one of the Minor Canons appointed, for his superior learning, to the office of schoolmaster. Chambers governed 15 years in his new office. There is some dispute amongst the historians of this church about the time of his death, but it is generally agreed that the tablet to his memory is dated wrong, and that he died in 1556. There were two monuments erected to him, by his own orders, before his death; and this circumstance may account for the error in the date upon the tablets. One of the monuments was a beautifully executed statue of himself, in white chalk, but it was destroyed in 1643. The bishop adorned the doors of the church with carved images and hieroglyphics, one of which at the west front represents a sinner tormented by devils, though it is now much defaced. From the death of Bishop Chambers to the accession of Richard Howland, in 1584, nothing of importance occurred. It was during his rule that the unhappy queen of Scots fell a victim to the vanity and jealousy of Elizabeth, in the castle of Fotheringhay.[17]
