The vertical section of the keep, upon a line east and west, looking south, and here given, shows on the ground floor “Little Ease,” and the lower store-room; on the first floor, the chapel crypt, and the upper store-room. On the second floor is the chapel nave and aisle, and the lower armoury; on the third floor, the chapel triforium and space above the vault, and the upper armoury or council-chamber. The chapel, dedicated to St. John the Evangelist, is a rare, if not a singular example of such an apartment, so large and so complete, in the original and interior arrangements of a Norman keep. It is in plan a rectangle, 40 feet by 31 feet, terminating eastward in a semicircular apse of its full breadth; its extreme length, therefore, with this addition, being 55 feet 6 inches. It is divided into a nave and aisles, the latter being continued as a chevet round the apse. [Illustration: THE KEEP.—VERTICAL SECTION, EAST AND WEST.] The nave, 14 feet 6 inches broad, and 40 feet long, has an eastern apse, giving 7 feet 3 inches additional for the altar. It is divided from the aisles by four columns, and a western respond or half-column, on each side; and by four columns which contain the apse. The whole support thirteen arches. The columns are cylinders of 2 feet 6 inches diameter, and 6 feet 6 inches high, with plain torus bases resting upon a square stone of two stages, giving, with the base, an additional 20 inches. The capitals vary in pattern, some being plain cushion, others a combination of four cushions, giving a scalloped or indented outline in the elevation; others, again, are chamfered at the angles; and others finished with a stiff rude volute of an Ionic aspect. The capitals of the eight eastern columns are unfinished, having a block in the form of a Tau, or cross-potent, upon each face, evidently intended to be carved into the usual central flower of a Corinthian capital; and the astragal is set round with a row of stiff upright feathers, like a plume. Each capital has a plain abacus, with varieties of the half-round, ogee, and hollow mouldings, excepting the western responds, of which the faces of the abaci are cut into the star-pattern found in early Norman work. Beneath is a light cable bead. These capitals vary from 34 inches to 40 inches square, and are 22 inches high, so that from the floor to the top of each is 10 feet. Each capital is a single block, and each abacus a single slab. The thirteen arches springing from these capitals in the nave are 7 feet, and in the apse 2 feet 9 inches, diameter. The five apsidal arches are stilted, the rest semicircular, the crowns of all being level. The whole are perfectly plain openings in a 22-inch wall, without chamfer or rib.
