The west facade of St.-Gilles presents one of the most important sculptural programs of Gaul, but its date remains problematic. Unresolved questions of style are aggravated by physical irregularities in the facade, particularly the figured frieze, that have been attributed to a change of plan. Inconsistencies in individual frieze reliefs have been ignored or interpreted solely according to that theory. The scope of these inconsistencies and their import to the frieze and facade chronology are studied.
