t of each of these mouldings forms about three-quarters
of the circumference of a circle. The characteristic Early English
dog-tooth ornament is carved round the moulding of the central light,
those round the other lights are not thus decorated. The whole group is
surrounded by a label following the curves of moulding, with carved
heads at its terminations and points of junction. The six cusps of the
moulding are ornamented by bosses of carved foliage.

To the south side of the presbytery, between the south window and the
Beaufort tomb, the triple #Sedilia# and the #Piscina# are situated: each
of these is covered by a canopy of fourteenth-century work. These were
extensively repaired at the time of the restoration. The Beaufort altar
tomb is the finest monument in the church. On it are two recumbent
figures carved in alabaster, and although there is no inscription it is
certain that they represent John Beaufort, Duke of Somerset, and his
wife Margaret. John Beaufort was son of another John Beaufort, Earl of
Somerset, who was brother of the celebrated Cardinal Beaufort, and son
of John of Gaunt by his mistress Catherine Swynford, a family afterwards
legitimatised by Parliament. This second John Beaufort distinguished
himself in the French wars of Henry IV., who in 1443 gave him a step in
the peerage, creating him Duke of Somerset. His wife Margaret was, when
he married her, widow of Oliver St John, and it is thought that after
the death of her second husband in 1444 she married again. This John and
Margaret, Duke and Duchess of Somerset, are famous on account of their
daughter the Lady Margaret, so well-known for her educational endowments
and for the fact that after her marriage with Edmund Tudor, the Earl
of Richmond, she became the mother of that Henry Tudor who overthrew
Richard III. at Bosworth, and was crowned King as Henry VII. Here
on this altar tomb their effigies remain in a wonderful state of
preservation, their right hands clasped together, angels at their heads,
his feet resting on a dog, hers on an antelope. He is completely clad
in armour, the face and right hand only bare--the gauntleted left hand
holds the right hand gauntlet, which he has taken off that he may hold
the lady's hand. She is clad in a long close-fitting garment. Each of
the two wears around the neck a collar marked with the letters SS. At
the apex of the arch above their tomb ha
