included the eastern bays and aisles of both transepts. The style of the
architecture speaks for itself, "the stones tell their own tale," and
the most careful study, and the most painstaking investigations, have
failed to detect the slightest break in the continuity or character of
the work. This applies to the whole of the eastern part of the
transepts, excepting of course the alterations that were made in later
times. As Martin remained abbot till 1155, it is probable that he went
on with his building after the choir had been opened, and that this work
in the transepts was done in the latter part of his abbacy, but there is
no record of it.

Of Abbot William of Waterville (1155-1175) we are told that in his time
were erected the transepts (_ambæ cruces_) and three stages of the
central tower (_tres ystoriæ magistræ turris_). This does not contradict
what has been said above as to the eastern part of the transepts being
built in Abbot Martin's time. For the walls and aisles to the east only
would be in position; and his successor might well be credited with the
erection of the transepts, if he built the ends and western walls, and
roofed in the whole. It is tolerably clear also that this same abbot
must have built the two bays of the nave adjoining the central tower. A
tower of three stages, presumably of the massive character that marks
all large Norman towers, must have had some western supports. Two bays
of the nave would act as buttresses; and it is easy to see the
difference between these two bays and the rest of the nave. Apart from
many minute points of difference which only an expert architectural
student could fully appreciate, there is one conspicuous variation which
all can see. This is in the tympanum of the triforium arches; in all
four instances we notice rugged ornamentation here which occurs nowhere
else in the nave.
