This is an experimental section where John James is attempting to identify the carvers though the use of common templates and/or a recognisable manners of carving. Such a large-scale analysis of all the capitals in these buildings has not been attempted before. As an ongoing enterprise that is still in its infancy, we seek your input. John believes this has the potential to increase our understanding of how they worked and to provide a more solid basis for dating than we have had.
Choir foundations to bases of eastern towers with apse sills like St-Denis and thin buttresses angled to centre, possibly for flyers; plans for buttresses altered near floor level suggesting a significant delay and with a joint at chapel drips; the original single-light windows to the chapels are also like those at Saint Denis. The capitals suggest a date after Saint Denis and before Senlis, some time in the mid-1140s.
Eastern tower bases to vaults, in which the bases indicate that the EN1 and ES1 piers that support the eastern towers were erected after the walls of the chapels, and from such poor stone that the majority of their capitals have had to be replaced; bases have square rib plinths that were designed to support aa,f,r,f,d, and as work progressed the north tower remained a few courses more advanced than the south
Choir gallery and arcade arches were supported on the old church because the capitals on the gallery jambs are earlier in manner to the ambulatory drums underneath, as in st Remi and Noyon; and as chapel and ambulatory vaults were built together, both would have been built at this time.
