The Lady Chapel, due in part to De Lucy and in part to Priors Hunton and Silkstede, is of rectangular shape, the easternmost portions being added about 1524. It should be noticed that in De Lucy's work the central aisle is but little higher than the laterals, which still have their eastern walls, whereas the actual material of the Lady Chapel east wall was erected by Hunton. The north and south walls exhibit De Lucy's Early English arcades and lancets, while they become Perpendicular at the eastern end, and the east window is of the same period. This large seven-light window shows "transom and tracery of a peculiar kind of subordination, or rather inter-penetration of patterns, well worth a careful study" (Willis). The stone work of the interior is quite plain, but a large portion of the wall space is concealed by some richly-carved wooden panelling added by Bishop Fox. Seats, desks, and screen are also of fine workmanship. Where the walls are not hidden by wood-work are the very faint remains of some curious old mural paintings of the miracles of the Virgin, executed under the direction of Prior Silkstede in 1489. These frescoes are decidedly archaic, but they are extremely interesting. Starting from the south side the nineteen pictures represent:—
1. Miracle of an image of the Virgin bending its finger to prevent a young man taking off a ring which he had placed on the image that it might not be lost or injured while he played at ball. By this the young man was won to monastic life.
2. Protection and honour conferred by the Virgin on an ignorant priest, who knew and could sing only one mass, which was in honour of her.
3. Prior Silkstede kneeling before Virgin, saying: "Benedicta tu in mulieribus." Beneath is the following:—"Prior Silkstede also caused these polished stones, O Mary, to be ornamented at his expense."
4. Jewish boy, after receiving the Eucharist, thrown into a furnace by his father, but delivered from the flames by the Virgin.
5. Famous portrait of the Virgin, carried in procession by Pope Gregory to allay a fearful pestilence. During the procession the destroying angel is seen sheathing his sword.
6. A widow receives back her son who had been kidnapped, and thereupon restores the silver image of the child Jesus, which she had taken from the image of the Virgin on losing her son.
7. Virgin assisting woman taken ill on pilgrimage.
8. Virgin enables boys, with ease, to raise that which strong men could not.
