It is thus apparent that the edifice was to a great extent remodelled--the north and south aisles of the choir, and the central and recently renewed side aisles and chapels of the nave, being the only portions left untouched. The south aisle of the nave had (as above mentioned) been remodelled some fifty years before, when the five chapels were added to the south of it. The south wall of the south aisle had then been removed, and its place supplied by the pillars which connected it with the five added chapels (Fig. 829); while at the same time both aisle and chapels had been vaulted with finely groined vaults, having numerous moulded ribs springing from corbels inserted above the capitals. 1. The first of the alterations of about 1460, above mentioned, is the lengthening of the choir by one bay. The original east wall, no doubt, [Illustration: FIG. 829.--St. Giles’ Collegiate Church. South Aisle of Nave and South Chapels.] stood where the two eastern free pillars now stand; and, the wall having to be removed, the two new pillars (Fig. 830) were substituted for it. These pillars and the two responds against the east wall tell a very remark-able [Illustration: FIG. 830.--St. Giles’ Collegiate Church. Choir.] [Illustration: FIG. 831.--St. Giles’ Collegiate Church. The East Pillar, South Side of Choir.] and interesting story, and prove beyond doubt the date of the work. Each capital contains four shields (Fig. 831), which are explained by Dr. Laing in the following manner:--The north or, as it is commonly called, the king’s pillar contains in its sculptured cap a series of heraldic emblems of special significance. The shield facing the east contains the royal arms (Fig. 832), with a label of three points, which, no doubt, denotes the infant heir to the throne, James III. The shield facing the west is also carved with the royal lion rampant, with its double tressure; but the top of the shield is unfinished. This is probably the arms of James II.
