of intersection between the transept and the nave the supports of the
central tower rose. Between this and the west end there were eight
arches in each of the arcades opening north and south from the nave
into the aisles. Beyond the crossing towards the east there were three
similar arches in the arcades which connected the apse with the large
piers of the central tower. These three bays, together with the apse,
enclosed the chancel; and this comprised the sanctuary, which was that
part within the apse itself, and also the presbytery, or choir of the
priests, which occupied the remaining space between the apse and the
arch into the transept beneath the tower. At a later date the
accommodation of the choir was increased by making it occupy part of
the space farther to the west. Possibly it projected into the nave. At
the west end of each of the aisles of the nave a tower was placed, and
between these two towers was the chief public entrance to the church.
From the subsequent history of the structure it would appear that the
two western towers had been built up and finished, so far, at least,
as was necessary to allow of the completion of the nave with its
aisles and roofs. The same may be concluded of the central tower.

This latter probably rose only just above the ridge of the roofs. To
carry it up so far would have been dictated to the builders by
structural reasons; for such a height would be required to help the
stability of the piers and arches below, since they had to resist a
variety of opposed thrusts. But even this tower, low as it no doubt
was, like others of the same date, did not survive the dedication more
than about twenty-six years. The whole building was covered with a
high-pitched wooden roof over the nave, transept, and chancel; and
beneath the outer roof there was a flat inner ceiling of wood formed
between the tie beams, similar to those now to be seen at Peterborough
and S. Albans. The north and south aisles of the nave were protected
