sely corresponds with the Dean's Chapel on the
north side of the church. In general style there is also some resemblance,
but the vaulting of the roof is quite different; it is described by
Professor Willis as "as a complex lierne vault of an unusual pattern, but
resembling that of the north transept of Gloucester Cathedral, which dates
from 1367 to 1372." The exact date and the name of the builder of this
chapel are alike uncertain, but it probably replaced the old Chapel of St.
Michael at some time towards the end of the fourteenth century, and Willis
comes to the conclusion that it is most probable that its erection may be
ascribed to Prior Chillenden, and that "it formed part of the general
scheme for the transformation of the western part of the church."

A curious effect is presented by the tomb of Stephen Langton, who was
archbishop from 1207 to 1228, and is famous as having compelled King John
to sign the Great Charter, and also as having divided the Bible into
chapters. His tomb, shaped like a stone coffin, is half in the chapel and
half under the eastern wall, and Professor Willis considers that it was
originally outside the wall, in the churchyard; "and thus the new wall,
when the chapel was rebuilt and enlarged in the fourteenth century, was
made to stride over the coffin by means of an arch." The reverence in
which Langton's memory was held is attested by the fact that his remains
must have lain under the altar of the chapel, a most unusual position
except in the case of celebrated saints. In the middle of the chapel is a
very beautiful and interesting monument erected by Margaret Holland, who
died in 1437, to the memory of her two husbands and herself. The monument
is of alabaster and marble, and represents the lady reposing with her
first spouse, John Beaufort, Earl of Somerset, and son of John of Gaunt,
on her left, and Thomas, Duke of Clarence, her second husband, on her
right. The latter was the second son of Henry IV., and, so, nephew of John
of Somerset the first husband; he was killed at the battle of Bauge in
1421. Leland thinks that this chapel was built expressly for the reception
of this tomb: "This chapel be likelihood was made new for the Honor of
Erle John of Somerset," but it is probably of rather earlier date than
would be allowed by this theory. The figures of Margaret and her two lords
are very fine and are interesting examples of fifteenth century costume.
As such they may be contrasted wi
