The corresponding chapel to the south is #Bishop Langton's Chantry#, though the work is partly De Lucy's, including the walls and the early vaulting shafts. The defaced front-screen and the oak-panelling all round are very rich examples of late Gothic, and the stone vaulting has been compared in point of elaboration with that in the chapel of Henry VII. at Westminster. On the groining, at the junction of the ribs, is carved Bishop Langton's rebus, consisting of the musical sign for a "long" upon a tun, while his motto _Laus tibi Christe_ also occurs. It is supposed that the magnificent carved vine on the upper part of the oak-panelling which runs round the chapel originally formed the rebus of Langton's see, the tun from which it sprang being now lost. The woodwork, which is certainly one of the most striking things in the cathedral, is unfortunately mutilated, as is also part of the heraldic work on the entrance door. At the east end of the chapel above the former altar there is a row of seven tabernacles, under which is a cornice which was originally gilt and painted. The statues which once occupied the tabernacles are no longer extant. The central tomb here is that of Bishop Langton himself. Queen Mary's chair now stands in this chapel; it is in a wonderful state of preservation for its age, and the woodwork is still sound. The entrance to the #Crypts# is in the north transept, as was noted above. They are three in number, the main division stretching from the eastern tower-piers to the first piers of the retro-choir. It consists of a central room divided by a row of five columns in the middle, with an apsidal eastern termination, and is flanked by two aisles with square eastern ends. The well here is said to be considerably older than the building above it. From this opens out a narrower crypt, which also has five columns down the centre, while its apse reaches to the eastern end of the retro-choir. These crypts cannot, as some have supposed (and the tradition still survives), form part of the old Saxon church, since it has been fairly established that the site of this was not that of the present building. The plan of the chambers is in perfect accord, as Willis says, with that of Norman churches in general. The main crypt shows by its circular apse what was the form of the east end in the old Norman church. The actual work is strikingly like that of the transepts, the peculiar thin square abacus, combined with a round capital, being a noteworthy point in both these portions of the building. The third crypt, which is narrow like the second, is rectangular in shape, and its vaulting rests on columns. It is Early English in architecture, and is contemporary with De Lucy's work in the upper part of the church. In 1886 the crypts were to a great extent cleared out to their original level, a vast quantity of rubbish being removed. Many fragments of early work still remain, though in too mutilated a form to indicate where they originally stood.
