There are two rows of dog-tooth moulding round the windows in the aisles of the north transept, but only one in the south.

The clerestory shafts in the aisle of the north transept are bolder than in the south, and the capitals, especially on the east side, are more elaborate and beautiful.

The extra Decorated pillar on the west side of the north transept has already been noted.

The ends of the transepts are, of course, entirely different in arrangement. Purbeck marble is used lavishly all over the transepts; as, for example, alternately with stone in the main piers, on the shafts of the aisles, and in the triforium and clerestory. The main vaulting shafts are altogether of Purbeck.

The arcade at both ends of the transepts is entirely without Purbeck marble.

In the south front the shafts of the lowest row of windows are alternately of Purbeck and stone. The arcading above the door is wholly Purbeck, with dog-tooth mouldings of stone. The shafts of the central windows are Purbeck with alternate dog-tooth mouldings, and there are Purbeck shafts at the side of the rose window.

There are also Purbeck shafts on each side of the door, beginning above the arcade below.

In the north front, the shafts of the five sisters and of the five lancets above them are alternately marble and stone.

As has been said, the proportions of the bays in the transepts are very different to those of the nave. The triforium is much larger, and the clerestory much smaller. The main arches, slightly smaller in proportion than those of the nave, are extraordinarily rich and beautiful in detail. Their mouldings are very complex and deep, and are varied with dog-tooth and billet ornament.

The piers are perhaps too thin, though beautiful enough in themselves. They are made up of alternate shafts of Purbeck marble and stone. Those of Purbeck are ringed half-way up. The Decorated piers are altogether of stone, and not ringed at all. The arrangement of the shafts is not quite so bold and various as in some other Early English work—the choirs of Ely and Worcester, for example.
