The Nave, notwithstanding the years it took to build, the change of architecture that was coming into use as it was being finished, and the alteration in plan that was decided upon towards the end, is a very complete and almost uniform structure. There are ten bays, all having round arches; in the triforium each large arch has two smaller ones beneath it; and in each bay of the clerestory is one high arch and two smaller ones. The triforium arches in the two easternmost bays, on both sides, have the hatchet ornamentation in the tympanum; this may either mark the limits of the old Benedictine choir, or may simply suggest earlier work. Almost the only indication of distinct later work, as we proceed towards the west, is in the different forms of the bases of the piers. The arcading of the aisles curiously changes towards the west in both aisles, but not at corresponding points; the change consists in the reversing the interlacing of the arches. The third pillars from the west end on either side are not really, strictly speaking, pillars at all. They were built as supports to two western towers which it was intended certainly to erect at this point, even if they were not at least in part built. There are many other little details in the neighbourhood of these piers, all confirming Mr Paley's discovery with respect to these contemplated towers, one at any rate of which he thinks was actually erected. The pillars are cylindrical with numerous attached shafts. In addition to the changed form of the bases, careful observers can detect proofs of later work in the capitals of the shafts in the triforium. In front of each pier a shaft rises to the roof; and on these the original ceiling rested. On some of the piers in the south aisle, near the west end, may be seen several very curious masons' marks. In the nave is a very massive pulpit given in 1873 by the family of Dr James, for forty years Canon, bearing an inscription to his memory. It is from the design of Mr Edward Barry, and was meant to be in keeping with the Norman architecture of the nave. The central shaft is of Devonshire marble, the main body of the pulpit of red Dumfries stone, and some of the smaller pillars are of green Greek marble. At the angles are four large figures of the Evangelists. There is a wooden eagle lectern, carved by the late Rev. R.S. Baker, behind the choir-stalls on the south side.

The Nave Ceiling is very curious and remarkable. If originally flat, and supported on the tall shafts last mentioned, it would be just above the great arch of the central tower before that was altered from the round form. It is supposed that this was the case; and that when the pointed arch was substituted the central compartment of the ceiling was raised, and the two outer ones made to slope as we see it now. But if the Norman roof was flat, its outer compartments would manifestly not be broad enough to fill the space now occupied by the sloping sides. And yet there is no alteration in the style of ornamentation: nor are the diamonds, which are divided by the line where the slope joins the horizontal portion, unduly elongated, as would seem to be necessary in the part nearest the wall. Some change was clearly made when the Decorated arches were built; for above the Norman cornice on which the roof was originally laid, there is now a length of painted wood containing coats of arms obviously of later date than the ceiling. It is not possible to pronounce with certainty on the question. But considering (1), that the whole ceiling was certainly raised in consequence of the superior height of the tower arch (2), that no difference can be detected between the centre compartments and those at the side in the patterns, and (3), that additional height has been secured by the Decorated boarding above mentioned, the most probable solution seems to be that the whole is the original Norman work, practically unaltered, and that it was never flat, but had always sloping sides as at present. All agree that the style of the painting is perfectly characteristic of the period. The divisions are of the lozenge shape; in each lozenge of the central line is a figure, and in each alternate one of the sides. The middle set has more elongated lozenges than the others. The borders are black and white, with some coloured lines, in odd zigzag patterns. The figures, which are mostly seated, are very quaint and strange. Some are sacred, some grotesque. We can see S. Peter with the keys, kings, queens, and minstrels; we find also a head with two faces, a monkey riding backwards on a goat, a human figure with head and hoofs of an ass, a donkey playing a harp, a winged dragon, a dancing lion, an eagle, and other curious devices.

The Font stands between the first and second piers on the north side of the nave; the basin is of a local marble of thirteenth century date, but the lower part is modern. For many years it was used as a flower pot in one of the prebendal gardens, whence it was rescued by Dean Monk and ultimately restored to its original use in the south end of the western transept. It was placed where it is in 1920. Another font had been erected in 1615, as appears by an entry in the cathedral register of that date, when the son of one of the prebendaries was baptized "in the new font in the bodye of the Cathedral Church here."

The West Transept extends beyond the aisles. The huge pointed arches covered with Norman mouldings are very remarkable. The arcading which goes round the lower part of the aisle walls was continued round the east sides and the ends of this transept, but it has all been hacked away, and the walls now are flat. The position of the arcade is very plainly to be seen. The south end in 1921 was again restored to its former use as a chapel by the Dean of Winchester, Dr. Hutton. The north end of this transept is used as a vestry. It is screened off, with the adjacent bays of the north aisle, by some of the woodwork that has been removed from Dean Monk's choir. From these specimens the general character of the whole can be easily gathered.
