the plain parapet has over it a pierced battlement.

The #East End#, as it now stands, is some 110 feet beyond the original
Norman termination, and presents a square face, projecting with a flat
parapet beyond the high gable over the actual east window. The Norman
apse was demolished about 1320 in all probability, and the present
polygonal end substituted for it. It seems that originally the aisles of
the Norman presbytery continued round this apse, which was flanked by
two small towers. The eastern chapel may have been dedicated to the Holy
Trinity as at Canterbury, and probably extended as far as the western
arch of the present Lady Chapel. The central gable of the old
termination, rather acute in form, is richly decorated with panels and
crocketting, and is crowned by a tabernacle wherein Bishop Fox is
represented leaning on the pelican. "Three of the panels in the centre
are pierced and glazed, forming a small square-headed window; and under
it is a door opening upon an _alura_, behind a crenelated, panelled, and
pierced parapet, over a cornice with bosses, at the base of the gable,
and just above the east window" (Woodward). The Perpendicular east
window has seven lights, and resembles, in the form of its head,
Wykeham's windows. A portrait bust of Fox has been discovered on the
north corbel of the hood-mould of this window, and the flying-buttresses
(which, as Willis pointed out, the jointing of the masonry proves to be
later insertions into the clerestory walls) have the pelican carved on
them. The whole gable is flanked by richly canopied octagonal turrets,
on which the flying-buttresses abut. The lower part of the east window
cannot be seen from below, being lost behind the roof of the chantry
aisles.

The whole of the eastern arm of the cathedral is curiously mixed in
style, furnishing examples of Early English, Decorated, and
Perpendicular architecture. Beyond the main east gable just described
projects a low Early English structure of three nearly equally high
aisles, of which the central or Lady Chapel has received a further
Perpendicular addition. There has been apparently a slight subsidence of
the Early English walls, which has caused the irregular look of the
arches in the interior of the southern retro-choir aisle (see page 69).
Above the plain string-course of the retro-choir there is in each
compartment, under a level parapet, an
