the column, there is
no proper base. Each column has a shaft at the front and another at the
back, the former carrying the rim of the arch and having a stilted
polygonal base but no capital, while the latter has capital as well as
base (both polygonal), and helps to carry the aisle-vault. The spandrels
of these arches are filled with panelling, in which are several shields
(one bearing the arms of Pigott). The triforium again shows in each bay
a round arch; indeed, no better example than this choir could be found
of the truth that the form of the arch is not a safe guide to the date
of a building, but was often dictated by convenience; for here in the
triforium are round arches, of which some belong to the twelfth, others
to the thirteenth, and others to the sixteenth century. The fact that
the distance between the string-courses was already settled by the
Transitional bays, compelled the later builders to make their arches
round, as a pointed arch of the requisite width would have been too
tall. Here the round arch, which is again flanked by two panels,
comprises three cinquefoil lights, and the mullions are carried up
through the head. The panels are pointed and divided each into two
cinquefoil divisions. The Perpendicular clearstorey windows have their
rims moulded, but are not splayed. The vaulting-shafts resemble those in
the Decorated bays, but their corbels are polygonal and have the sides
slightly hollowed, and the abacus of the capital is a half-lozenge. The
string-courses have not been made to match either the Transitional or
the Decorated. The whole of this Perpendicular work is of very late
character, and justifies the belief that it was the last important
alteration in the fabric before the dissolution. Moreover, where it
meets the tower there seems to be a 'straight joint,' which indicates
that these bays are at any rate later than the tower piers.

East of the Perpendicular pillars the next column is Archbishop
Roger's, and perhaps the next also, with the exception of its capital,
which has two rings upon the necking, with the rectangular top imposed
directly upon them and chamfered beneath, while the abacus (which is of
limestone) is convex.[93] The respond against the east wall is again of
the old pattern, but without the circular plinth, and its capital
resembles that just described. In the westernmost of these southern
Decorated bays three styles meet. The lower order of the arch seems
again to be Tr
