Quivil's successor was Thomas De Bytton, Dean of Wells. Under his guidance the work of transformation planned by his predecessor was loyally continued, for he faithfully adhered to the original design. Though Bytton appears to have been less active outside his diocese than many of the Exeter bishops, his mode of life must have commended itself to a large circle. A grant of forty days' indulgence was the reward of all those who availed themselves of his spiritual ministrations, or offered prayers for his prosperity during his life and after death. Among the signatures appended to the document notifying this singular privilege are those of numerous archbishops and bishops, among them being those of the archbishops of Cosensa and Jerusalem, and Manfred, Bishop of St. Mark's, Venice. "The seal of Manfred," Dr. Oliver says, "is perfect; he stands robed, with a piece of embroidery on his alb. The crozier is simply curved. His legend is S. MANFREDI. DEI. GRA. EPISCOP. SCI. MARCHI." It was dated at Rome in the year 1300. Possibly Bytton's great learning, by which he had risen to be Professor of Canon Law at Oxford and Pope's Chaplain, was partly the reason of so notable a compliment. But the noble work he was doing in the cathedral church of his diocese, we may hope, had not a little to do with the honour. For to him we owe the entire transformation of the choir with its aisles. Bytton's labours were, indeed, very great. We hear of large quantities of stone procured from Barley, and of sandstone from Salcombe and Branscombe. He also put a good deal of stained glass into the windows; so that in the eleventh year of his episcopate the following item is recorded: "Master Walter le Verrouer for setting the glass of the upper gable and of eight upper windows, and of six windows in the aisles of the new work, in gross, L4 l0s." Bytton was succeeded, in 1308, by Walter de Stapledon, the most famous of all the bishops of Exeter. A younger son of Sir Richard Stapledon of Annery, his appointment was the first of a succession of aristocratic nominations. He, too, had been a professor of canon law at Oxford, was a chaplain to the Pope and precentor of the cathedral church of Exeter. The feast given after his enthronement was unusually splendid, the revenues for a whole year being spent on the festivities. It seems as though, conscious of his great talents, he determined to signalize his accession to the episcopal office by some event of unusual magnificence. It must be remembered that Exeter was at this time one of the largest and richest sees in England. As Professor Freeman has pointed out, "The Bishop of Exeter, like the Archbishop of York, was the spiritual head of a separate people." Stapledon set about expediting the work of transforming the cathedral into the Decorated style in vigorous fashion. The Fabric Rolls record that he himself gave the (then) enormous sum of L1,800 towards defraying the cost. His generosity encouraged others to subscribe liberally
