The ribs of the vaulting are square. The vaulting supports have abaci/capitals of the profile square, flat, square, hollow chamfer, beading (or nailhead, Leask, 1960, 37) between fillets, followed by an overhanging plain impost. The supports die into the wall with foliage terminals. In place of keystones the masonry at the apices is composed of a series of symmetrical blocks.
