doorways and of the east aisle, there is carved in each bay an engrailed cross, the one limb running along the crown of each arch, and the other downwards from this on each side. But in the north and south aisles, in the three bays west from the doorways, the engrailed band is only continued along the crown of the arch, the other limb being omitted, which may possibly be meant to distinguish the more sacred part of the edifice.
The eastern chapels are the only part of the building in which there is groined vaulting. The compartments are oblong, and have pointed cross arches (Fig. 1083), the diagonals meeting at the apex. Elaborately carved pendants, about 4 feet long, occupy the place of the usual boss; while at the springing of the arches, against the east wall, great projecting horns, resting on curved corbellings or cones above the caps of the wall shafts, radiate outwards and downwards, one horn to each rib, so that they are in groups of three.

The object of these curved cones, with their projecting horns, may be explained as follows:—It will be seen on referring to the Plan (see Fig. 1070) that the centre line of the east chapels is not in the centre of the space between the two eastmost buttresses, and consequently not in line with the centre of the north and south windows between those buttresses. In order to make the centre line of the vaulting coincide with the centre of the windows, it was necessary to introduce some kind of support for the foot of the east arches, at a distance of about 2 or 3 feet from the east wall. The above cones and horns were introduced for this purpose, and from them the vaulting on the east side springs. In connection with this arrangement, the late David Roberts, R.A., contended that the "east wall of Rosslyn had been pulled down and set further back, to give 3 feet more room."[1] But this supposition finds no warrant whatever from an
