Between two immense pillars at the entrance to the nave were the heavily ornamented gilded brass tombs of the Bishops who founded the Cathedral. That on the left was Geoffroi d'Eu, who died in 1236, and on the right was that of Evrard de Fouilloy, who died in 1223. Each shows a recumbent figure in full robes inclosed in Gothic canopies with pointed arches, and sustained by lions. The great organ loft was beneath the magnificent "rose de mer" window which was filled with the arms of the house of Firmin de Coquerel. In the choir were one hundred and ten carved stalls, said to have been designed and made by local artists of Amiens, and these alone would have made any cathedral noteworthy. According to that eminent authority, Mr. Francis Bond, the height of the nave and the aisles is three times their span, and this feature gave the effect for which the architect worked, that is, a splendid blaze of luminosity shining down into gloomy and most mysterious shadow. This blaze of light and color came not only from the clerestory, but also from the triforium, in which the superb blue glass shone with celestial splendor. The meaning of the word "triforium" is perhaps somewhat obscure to all save architects. Herbert Marshall * defines the word as "Applied to the ambulatory or passage, screened by an arcade, which runs between the pier arches and clerestory windows and is considered to refer to the three openings, or spaces, 'trinae fores,' into which the arcading was sometimes divided. It probably has nothing to do with openings in multiples of three, nor with a Latinised form of 'thoroughfare' as suggested by Parker's Glossary, although the main idea is a passage running round the inside of a church, either as at Westminster, in the form of an ambulatory chamber, or of a gallery pierced through the main walls, from whence the structure may be inspected without the trouble of using ladders. M. Enlart in his 'Manuel d'Archéologie Française' derives the word from a French adjective, 'trifore,' or 'trifoire,' through the Latin 'transforatus,' a passage pierced through the thickness of the wall; and this idea of a passageway is certainly suggested by an old writer, Gervase, who, in his description of the new cathedral of Canterbury, rebuilt after the fire, alludes to the increased number of passages round the church under the word 'triforia.' 'Ibi triforium unum, hie duo in Choro, et in alâ ecclesiae tercium.'" * "Gothic Architecture in England."
