Wykeham's successor, Beaufort, was far less a bishop of Winchester than an English statesman. His contributions to the architecture of his see are very small. He did indeed so add to the hospital of St Cross as to make it almost a new foundation; but in the cathedral he only left one monument, though this Milner styles the "most elegant and finished chantry in the kingdom," lying on the south side of the retro-choir. Waynflete, who followed him, left another fine chantry in a corresponding position to the north. Under Bishops Peter Courtenay and Thomas Langton, the latter of whom has his chapel at the east end, next the Lady Chapel, considerable additions were made to the architecture of the cathedral, though most of the credit is due to the priors Hunton and Silkstede, who seem to have been chiefly responsible for the new work. This included a prolongation of De Lucy's Lady Chapel, carried out in all probability between the years 1470 and 1524; and the erection of the present side aisles of the presbytery, in place of the original Norman aisles. In the latter year (1524) the side screens of the presbytery were added by Bishop Fox, whose motto can be read on them. The work of Fox, whose chapel is behind the reredos to the south, began in 1510, and was carried out under early Renaissance influence. He found the choir and presbytery converted, to a great extent, to the Decorated style, though the Norman aisles remained. He completed the transformation, adding the above-mentioned screens, together with a wooden vaulting. He would probably have also replaced with his own work De Lucy's additions at the east end and the Norman transepts, had he but had the time. This, however, he did not live long enough to do, for he died in 1528. Roughly speaking, his work lies between the transepts and the Early English east end.
