The coloured glass was inserted to the east window in 1868, the south window in 1870, the west window in 1881. That in the east and south is by Hardman, in the west by Clayton & Bell. The glass in the south window forms a memorial to Adam Sedgwick, Professor of Geology at Cambridge, and canon of the cathedral for many years.
The room over the St. Luke's Chapel is used as the Treasury and Muniment Room.
The Bauchon Chapel—corrupted to Beauchamp—dedicated to St. Mary-the-Less, projects to the south of the third bay of the presbytery aisle past the tower, (marked B on [plan]). It was founded in the fourteenth century and the vault added in the fifteenth century. Its bosses represent the Life, Death, and Assumption of the Virgin. The chapel is now used as the consistory court. The bishop's throne, erected by Dean Lloyd late in the eighteenth century in the choir, has found a resting-place here.
A chapel, founded by Bishop Wakering, and which is said to have been used as the chapter-house after the demolition of that structure, came between the Bauchon Chapel and the east wall of the south transept. Its exact position is, however, doubtful. Harrod, quoting Blomfield, speaks of another chapel that was dedicated to St. Osyth, and which was paved in 1398.
The South Transept.—The screen and doorway filling the Norman arch between the south aisle of presbytery and the south transept should be noticed; it is an interesting piece of work of late Perpendicular design. There is a tradition that the Puritans disliked especially any tracery that took the form of this piece of screen work, calling windows in which it occurred "wicked windows." The intersection of the lines of the tracery made the monogram of the Blessed Virgin; and the fanatics destroyed such work wherever noticed. The tale is interesting, though we cannot vouch for its truth.
At the time the whitewash and paint covering the south transept was cleaned off a range of small arcading was discovered immediately under the line of the vault, as in the north transept, walled-up evidently when the vault was added.
The south transept had in Norman times a circular chapel projecting eastward similar to that remaining to the north transept. This was replaced by a later sacristy during the fifteenth century, and the line of this roof can be seen from the outside.
Across the south end there was formerly a stone screen built by Bishop Lyhart (1446-72) communicating with the vestry on the east side, and on the west with the staircase to rooms above the east walk of cloisters. These rooms, as we have before noted, were in all probability the dormitories of the monks, placed that they might so conveniently gain access to the cathedral for the services.
