The choir, both internally and externally, is remarkably symmetrical, the bays being all of the same dimensions, with only slight differences in the carving, which do not affect the general design. Thus (Fig. 1071) all the buttresses rise unbroken by set-offs to the wall head of the aisles, where the cornice continues round them, and they have all on the face canopies of the same size and style. Above the cornice on the ten buttresses on the north and south sides of the choir there rise on each two massive pinnacles, connected by a small flying buttress between them (Fig. 1072). The outer pinnacles, which are flush with the face of the buttresses, are square on Plan, and are decorated according to two alternate patterns (Fig. 1073), viz., canopied niches in the one, and large rosettes set in hollows in the other. The inner pinnacles (Fig. 1074), which rest on the thickness of the wall, are all practically alike. They are oblong on Plan, and are so placed as to offer most resistance to the flying buttresses, which are thrown across the aisles and rest upon them. The pinnacles are ornamented with rosettes on the angles, and crockets on the sloping top. The back of these pinnacles and the lower parts, where not seen from below, are left plain, without any ornament. The flying arches abutting against the pinnacles are carved with a revived Norman-like chevron. The pinnacles (Fig. 1075) on the buttresses of the east chapels are naturally somewhat different, as they have no thrusts from flying buttresses to counteract. There is only one pinnacle on each of these buttresses, and although they are all of different design, their effect corresponds with that of the outer pinnacles of the aisles of the choir. The back of these pinnacles is left unfinished (Fig. 1076), like those at the sides, but the portions visible are very elaborately carved. The windows of the aisles (see Fig. 1072) are all of two lights, and [Illustration: FIG. 1072.--The Collegiate Church of Rosslyn. North Doorway and Buttresses, &c.] [Illustration: FIG. 1073.--The Collegiate Church of Rosslyn. South Side of Choir, looking East.] have the same mouldings and orders of decoration both in the inside and outside of the wall, each jamb having two beaded shafts with carved caps. These beads are continued round the arches, and a large hollow [Illustration: FIG. 1074.--The Collegiate Church of Rosslyn.
