The glass of the east window, and of those on each side of it, is fourteenth-century work (_circa_ 1330). The east window is very fine, and is a Jesse window, showing the genealogy of our Lord from the "Stem of Jesse," with figures of kings and prophets, the Virgin, and finally the Crucifixion and the Judgment. In the north-east window is a figure of St. George. The _South Choir Aisle_ is of the same character as the choir; the windows are Decorated. Here is the famous monument of Bishop Bytton (1274), who was canonised, and whose tomb was much resorted to by pilgrims, especially by those who suffered from toothache. This is the most ancient example of an incised slab in England. Near the saint lie Bishop Beckington (1464), (who did so much for this Cathedral), and Bishop Hervey (1894). Below the effigy is a skeleton-like figure, which was intended to proclaim the moral maxim, _memento mori_. The iron-work should be noticed. Here also are the tombs of Bishop Harewell (1386), Bishop Hooper (1727), and Bishop Lake (1626). In the Chapel of St. John the Evangelist are buried Dean Gunthorpe (1498), the builder of the Deanery, and Dean Jenkyns (1854), who was responsible for the "restoration" of the choir. There is a fine Decorated piscina here. The _Retro-Choir_ is very beautiful. Slender piers of Purbeck marble support the fine vault. The carving of the capitals and bosses is very excellent. All is in the Decorated style. The _Lady Chapel_ is of the same date and style, finished in 1326. Its shape is pentagonal, and it is of rare beauty. The glass is of the same date as that of the choir, but has been restored. Angels bearing the instruments of the Passion appear in the east window, and in the tracery of the other windows are the Evangelistic emblems and heads of patriarchs and saints. At the south-east corner of the retro-choir was St. Catherine's Chapel. The glass is old and rich. There is a monument by Chantrey of John Phelips, and that of Bishop Drokensford (1329), who was bishop during the building of the Lady Chapel, and part of the choir is a graceful structure. At the opposite corner is St. Stephen's Chapel, and then we enter the north-east transept or Chapel of St. John Baptist, which contains Bishop Creyghton's tomb (1672), also monuments of John de Myddleton (1337), Bishop Berkeley (1581), Dean Forrest (1446). The _North Choir Aisle_ has the tomb of Bishop Ralph (1363), and an effigy, attributed to Bishop Giso (1088). Bishop Jocelyn caused several of these effigies to be executed, in memory of his predecessors. On the north is a door leading to a vaulted passage, which conducts us to the crypt of the chapter-house. Notice the curious carved heads in this passage. There is a curious stone lantern in the wall near the inner door. This crypt or undercroft is on the same level as the floor of the church, and was used as a treasury. It was finished about 1286, and is Late Early English.
