Note 275 — Irregular Four-Part Vaulting of Durham Cathedral

Ribs rising in a somewhat similar manner are to be found in the south of France, in the crypt of the church of Saint Gilles (Gard.) (Ill. in Lasteyrie, p. 263, Fig. 253) or the chapel of the Pont Saint-Benezet at Avignon (Vaucluse), where they mark the intersection of two flattened tunnel vaults.
