The southern tower has never been finished. The northern is full of inspiration. It is broken at two stages by double windows, the upper ones of the belfry being crowned by pediments and surmounted by rich, sunk tracery. The piers terminate in hexagonal pinnacles, while the tower, as well as the rest of the front, is finished with a battlement. The later blocking up of this, as well as the superimposed roofing, is very evident and disturbing. All the angles of buttresses, of windows, arches, splays, and pyramids,--those also crowning the bulky piers that meet the flying buttresses,--are characteristically and uniquely decorated with an ornamentation of balls. It softens the hard lines, splashing the surface with infinite series of small, sharp shadows and making it sparkle with life and light. The angles recall the blunt, blue teeth of a saw. The main entrance, as well as the first two bays of the naves underneath the towers, must originally have been of different construction from the present one. Inside the church, these bays are blocked off from nave and side aisles by walls, on top of which they communicate with each other as also with the eastern apse by galleries, probably all necessary for the defense of troops in the early days. Possibly a narthex terminated the nave back of the original entrance portal underneath the present vaulted compartment. The main entrance door is indeed a strange apparition. In its whiteness between the sombre tints of the martial towers, it rises like a spectre in the winding-sheets of a later age. It is distressingly out of place and time in its dark framework. "But in a great house there are not only vessels of gold and of silver, but also of wood and of earth, and some to honor, and some to dishonor."
