Image of the feature "IV. Interior Features: 4. Vaulting/Roof Supports: c. Nave: Nave aisle" at Cambridge.

A tunnel vault divided into quadripartite bays by transverse arches of various profiles rising from the imposts at the back of the nave arcade piers and falling onto half-round responds with 12thc. capitals. The diagonal ribs are plain and square in all bays except (i) and (ii). Here they are decorated with two rows of frontal soffit chevron (quirked rolls) separated by a half roll. The arrangement of the diagonal ribs is unusual in that they do not fall on the same respond capitals as the transverse ribs, nor anywhere near them. Instead they rest on 19thc. corbels to L and R of the respond capitals, and linked to them by sections of chamfered string course. The diagonal rib corbels are clearly not original and are not described, although they all appear in the photographs.
