Note 22 — PART I THE LOST CHAPEL

The great breadth of the footings of the rectangular part of Edgar's Chapel—about 6 feet 6 inches on the north and south walls—might easily have inspired a wrong opinion as to the substance of the walls themselves. But students of the work of this date are familiar with the fact that the flat and heavy fan-vaulted stone roofs of the Tudor period require, in addition to their external buttresses, a certain amount of interior support, which is given by building the walls as a series of hollow bays, the windows occupying the recesses, and the intermediate masses being brought out inwards, as piers or counterforts, the same being architecturally treated, so that the description elsewhere given of "piers as panellæ" is quite probably accurate, as a description of such features.—F.B.B.
