the work wholly destroyed, crocketted where before plain,
and the niche added in the place of the small light over the vault shown
in Britton's plate. In the side compartments the Perpendicular
battlementing was removed and the round cannon ball holes gratuitously
inserted.

The two pinnacles at the sides of the west window have since been
removed.

The earlier change in the central compartment of the front from Norman
to Perpendicular was effected by the additions of the door and window
still remaining. Bishop Alnwyck, who was translated to Lincoln in 1436,
added the doorway during his episcopate, and it was probably built right
over and covering the original Norman door and arcading. He also left
provision in his will for the west window, and this was added by Bishop
Lyhart (1446-72), to throw additional light on to the vaulting and
sculptures of the nave; from the inside it will be seen that it
completely fills the width of the nave, and follows the line of the
vault up.

The north side of the cathedral lies within the gardens of the bishop's
palace, which can be entered from the interior of the cathedral, through
a small door in the north aisle of the presbytery; the eastern end of
the cathedral also lies within a private garden, but permission to enter
it can usually be obtained.

#Exterior of Nave.#--Those portions of the precincts near the western
end of the cathedral are known as the Upper Close; and, walking round
the exterior of the cloisters, we come to the Lower Close. The nave on
the south side can be seen well either from the upper or lower Close,
and can be better examined in detail from the interior of the cloisters.
Its elevation consists of fourteen bays divided by flat Norman
buttresses. In height it is composed of what, at first sight, appears a
bewildering confusion of arches, arcades, and windows. Over the aisle
windows, hidden by the north walk of cloisters, comes a Norman wall
arcading; and over this the Norman triforium windows blocked up, and
again, above the later Perpendicular triforium, superimposed on the old,
and finished with a battlemented parapet. Behind this come the triforium
roof, and then beyond the original Norman clerestory, each bay with a
triple arch formation, the centre arch pierced for a window. And then
above all, the lead roof over nave vault.

The radical changes that have taken place since the nave was built by
Bishop Eborard (1121-45) consist of the insertion in t
