Fan vaulting, Peterborough Cathedral

On a recent visit to Peterborough we made a brief visit to the cathedral. I've said elsewhere in this blog that it is one of the most overlooked and least well-known of our major medieval cathedrals, a building of exceptional architecture that deserves to be much more widely recognised.

One of Peterborough's glories is the fan-vaulting of the retrochoir that is every bit as good as the more celebrated example at Gloucester. I've photographed and written about Peterborough's on more than one occasion on this blog, so I won't repeat myself here. On our recent visit the fall of the light and the visitors reminded me of the etchings and woodcuts of cathedral views popular in publications of the late eighteenth and early nineteenth centuries. These frequently show small, relatively insignificant people dwarfed by the enormous columns and arches. This effect is heightened by naves empty of seating, something that is seen only occasionally today. However, the retrochoir is usually seat-free, and though it is a smaller space with a lower roof, the visitors here reminded me of those early illustrations. It took a few shots, a few changes of position and a wait for people to populate the scene before I got the image I wanted.

The fan vault

The builders of our medieval cathedrals and churches were men of great ingenuity. The structural problems that they had to overcome - spanning ever greater spaces, erecting ever taller buildings, bringing light into the centre of wide buildings - were challenges familiar to architects today. The difference is that now we use computers, man-made materials, electricity and high technology in designing and building: in the middle ages it was muscle power, wood, stone and chisels that did the work.

Go into any major church and look up. The chances are that somewhere in the building you'll see vaulting. Springing from the forest of columns will be arches of stone that spread across naves, chancels, aisles and transepts. Often they will form star-like patterns across the ceiling, and if you look carefully you'll see the spaces between these ribs filled with carefully crafted pieces of stone. From the humble barrels and groins of the eleventh and twelfth century, through the quadripartite, sexpartite, tiercerons, liernes and stellar vaults of subsequent centuries, the progress of English Gothic vaulting is a story of increasing complexity and beauty, the final flowering of which is the stunning fan vault of the late fifteenth century.

This type of vaulting is peculiar to English Gothic architecture, with no parallels on the continent of Europe. It seems to have developed in the cloisters of Gloucester Cathedral around 1350. The best examples of the fully developed form are to be found in King's College, Cambridge, in Christ Church, Oxford, in Bath Abbey and in the retrochoir of Peterborough Cathedral (seen in today's photograph). Fan vaults differ from earlier vaulting in not comprising ribs and infilling, but rather halved concave cones with blind tracery carved on their surfaces. The organic forms and complexity of the decorative patterns make the experience of walking into a space roofed in this way incomparable!
