The Nave as it is (174 feet by 34¼ feet long, 67 feet 7 inches high) is quite unique, and differs considerably from other Norman naves, such as are to be found in the cathedrals at Ely, Norwich, or Peterborough, and in the neighbouring abbey churches at Tewkesbury, and Great Malvern.
The unique features here are the great height of the massive circular columns, fourteen in number, and the consequently dwarfed triforium or gallery running over the main arches. There are traces to be seen of the original Norman clerestory under the Perpendicular windows, and, judging from this, the height of the clerestory, as originally constructed, must have been but little less than that of the piers in the nave.
This Norman clerestory was altered at the same time that the roof of the nave was vaulted—viz. in 1242, in the time of Henry Foliot. This work was done by the monks themselves, who thought, as Professor Willis suggests, that they could do it better than common workmen. Their work is made of a light and porous kind of stone, treated with plaster on the under-side, and it was rendered necessary by the previous roof, which was of wood, having been destroyed by fire in 1190. Of this fire the piers certainly show the traces to this day, all having become reddened and slightly calcined. To make the new clerestory the whole of the original Norman work over the arcade of the triforium was removed, with the exception of the jambs of the side-lights (which extended beyond the arches of the triforium) and the wall between them.
Mr. Gambier Parry has also truly said that this work "was not an artistic success. They cut and maimed the features of the fine old Norman clerestory, and placed their thin weak work too low, destroying all the original grandeur of effect.... Here in this first pointed vaulting was a grievous and irreparable injury, destroying all sense of proportion throughout the building."
The vaulting shafts and the abaci are of Purbeck marble, and the capitals are of stone, as are also the corbels, bases, mouldings, and bosses. All the stonework was formerly painted. Mr Waller, who carried out the repairs to the nave, had excellent opportunities of seeing what was left of the painting underneath the many coats of whitewash; he wrote in 1856: "The painting may be thus generally described. The hollow of the abacus of the capitals was red, the lower member of the same, green; the whole of the bell red, the leaves alternately green and yellow, with the stalks, running down, of the same colours, into the red bell of the capital. The vertical mouldings between the marble shafts were red and blue alternately; the lower shafts green and blue, with red in the hollows, and the foliage on these also is green and yellow. Some of the horizontal mouldings are partly coloured also. The bosses in the groining are yellow and green, as in the capitals. All the colouring, which was very rich, was effected with water colours; in one instance only has any gold been discerned, and that was upon one of the bosses in the roof."
The fourteen piers are 30 feet 7 inches in height, or about twice the height of those at Norwich.[1]
The Norman piers have round or cushioned capitals. Their arches have zig-zag work in the outer moulding, and a double cable in the soffit. A cable moulding runs along just above the arches. The grotesque heads on the arches in the nave are said to represent the various mummeries of the Anglo-Saxon gleemen. A frieze of such may be seen at Kilpeck Church, in Herefordshire. It will be noticed how the cable moulding above the arches passes round some of the western vaulting shafts, and is cut away for those at the eastmost end of the nave.
Martin in his "Natural History of England" says: "The only blemish on the church is the enormous size of the pillars in the body of it, which are much too large in proportion to their height, and would have been reduced to a proper size, chiefly at the cost of the late Bishop (Benson), had it not been thought that it would have weakened them too much."
