It has the peculiarity of two double doors; and the large rose window composed of eight octofoiled circles surrounding a ninth, is of rare beauty. It is to be prized the more, too, because in the fourteenth century there was a plan for its removal, of which we have curious evidence: one of the side jambs and part of the arch of a large middle-pointed window having been inserted by cutting away the wall close to a buttress in such a way as to disturb very little of the original work, and yet to afford us a very curious evidence of the way in which alterations of this kind were made by the mediaeval masons, without the introduction of a single shore or support of any kind. Fortunately the alteration was stopped just where it ought to have been, after it had afforded evidence of the customs of the masons, but before it had destroyed a perfect first-pointed façade; and I suppose that by this time we have outlived the rage for middle-pointed work so far that it would be difficult indeed to find any one so wrong-headed as not to be grateful for the stoppage of the alteration at the point at which we see it now. Of the western façade I can say but little. It has been my fortune to see it twice, but an evil fate has so covered it with scaffolding at one time, and taken down and rebuilt so much at another, that I have only been able to guess at its general effect. The western doorways are adorned with sculpture, and this is almost the only place in the church in which figure sculpture still remains; but the whole exterior of the church is remarkable for the fine architectural character of the sculpture of foliage, which is used with special lavishness along almost all the string courses. I hardly know any finer work of its kind, but it is altogether conventional in its treatment, and arranged with very particular reference to architectural effect, the foliage in each bay being very nearly identical in its design. A peculiarity in the external effect of the church is the lighting of the triforium with separate windows, so that we have three heights of windows in the elevation belonging to the aisle, triforium, and clerestory.
