The nave appears, from the plan of the main piers (see Fig. 543) and the style of the responds against the west towers (see Fig. 550), to have been originally of first pointed work, and to have corresponded with the style of the choir, having no triforium, but a lofty clerestory with passage in the wall similar to that of the choir. Slezer’s view, taken before the destruction of the tower and nave in 1711, shows the clerestory of the nave complete, as above described. The arches of the windows are drawn as if circular, but this is evidently a mistake, those of the choir, which still survive and are pointed, being also drawn as if of circular form. The smaller piers of the outer aisles are evidently much later in style. The outer aisles would appear to have been the result of an alteration made apparently at an early date. Some fragments of the south aisle wall and south porch are apparently of first pointed style, but the outer aisles were undoubtedly restored in the fifteenth century. This is apparent not only from the style of the piers, but also from other indications. Thus, from the water table of the aisle roof against the north-west tower, it is evident that the roof has originally been of the simple shed form usually employed to cover a single aisle; while a second water table or groove has been formed to receive the span roof of the outer aisle. The small portion of the south wall of the nave which survives also confirms this view, as the form and ornament of the traceried windows (Fig. 551) assign them to the middle pointed period. The mode of junction of the outer aisles with the western towers also shows that the former were afterthoughts, as they project beyond the outer face of the tower wall in an awkward manner (see Plan). The junction of the south wall with the transept further indicates that the position of the former has been altered, as the lower part of a buttress has had to be cut away to make room for it, and the upper part of the buttress is left unsupported in mid-air (see Fig. 551). The rebuilding of the nave was, doubtless, carried out during the restoration subsequent to the ruin caused by the “Wolf of Badenoch,” in 1390. This restoration is in the style of the Scottish decorated work [Illustration: FIG. 551.--Elgin Cathedral. South Side of Nave.] which flourished during the fifteenth century. It should, however, be kept in view, as above pointed out, that some of the details of the west window of the south aisle wall and the south porch seem to indicate that the south wall had been extended to its present position in first pointed times. The restoration in the decorated period (after the great destruction of 1390) may, therefore, have proceeded on the earlier lines of the thirteenth century. The traceried windows of the south aisle are clearly of the decorated period. The corbels which carry the arches in the towers, in the bay of the interior next the west doorway, are also of fifteenth century work.
