 Conisborough Castle. 443 rib, of which the laterals are plain rolls, and the central worked in a chevron pattern. The area is thus divided into a western and an eastern half, of which the latter is rather the smaller, and may be taken to represent the chancel. Each division is crossed diagonally by two ribs, in section plain bold rolls, at the intersections of which are bosses of which the stones are big enough to form not only the boss, but about six inches of each of its four ribs, and in one case the division between the ribs is carved with flowers, with good effect. The bosses are carved, that to the west with a sort of cross moline, shown in the drawing, that next the altar with flowers. At the main angles the ribs spring from the shafts, but the triple cross ribs spring from a sort of prolongation of the capital and abacus of CAPITALS OF CENTRE ARCH, NORTH SIDE. the half-shafts. The shafts flanking the altar have capitals more ornate than the rest. The east window is a mere loop 6 inches broad and 2 feet 6 inches high, round-headed, and placed in a splayed recess of which the angles are replaced by a bold roll with foliated bases. This, again, stands within a second and shallower recess, flanked with small nook-shafts of which the capitals, delicately carved, range with those in the flanking angles. The head is cut in chevron pattern. Right and left are two small lights, quatrefoiled, but splayed inwards into circular recesses, 2 feet 8 inches diameter. Outside is a hollow moulding containing knobs or balls scarcely seen from below.
