almost grotesque excess of representing the shaft as broken in the middle! The favourite treatment of the Norman wall was to boast of its thickness exactly as the Doric shaft boasted of its supporting power--that is, by throwing away some portion of it. The face of the wall was recessed in panels, which were often filled with blind arcades. Modern builders often recess walls in this way in order to save material, leaving the wall thickest where it has most work to do; but the Norman and Lombard architects had no such economy in view. The windows and other apertures in the wall showed, by their shafted and moulded chamfers, the reality of thickness so great that the panelling and blank arcading was seen to _be_ no sacrifice, though it was a delicate and effective suggestion of one. This arcaded panelling is not only on one plane of the wall-surface. The recessed plane is again recessed in the same way, and yet again, arcade within arcade; and finally, in the higher portions of the wall, open galleries are worked in its thickness. In apertures the constructive rule which requires that the bevel or chamfer should slant inwards, to give the better light, is sacrificed to the opportunity of showing the mass of the wall; and the chamfer is external, and is so treated in its decoration as to increase in every possible way the appearance of thickness. The treatment of the doorway, which is the point from which the expressional idea may be best enforced upon every beholder, is very peculiar. When there is no advanced porch, a deep arch is practised through a great part of the wall, and the thickness is emphasised by an elaborate perspective of shafts and mouldings. Within this deeply recessed arch the actual doorway is often worked as a horizontal-headed aperture in a plane face of wall without chamfer; the remaining thickness of the wall, not shown by the recessed arch, being thus left to be measured by the imagination, which has already been excited by the display of thickness within thickness of decorated archway. The Norman architects, in order still further to increase this effect, had sometimes recourse to a device that can scarcely be justified by strict architectural principles, which should never falsify construction in order to heighten expression. A face of wall was advanced in front of the main wall of the building, in order to obtain a much greater depth of masonry for showing off the multitudinously moulded entrance-arch. This projection did not form a real advanced porch, having its proper ecclesiastical purposes, but was nothing but a boast and display of mass in the masonry which really had no existence, the advanced face of wall concealing the fact that there was only mass enough behind it to allow of this misleading display. It may be said that the Gothic spire is constructed simply for display. It is quite true; but it is avowedly so constructed, and there was no concealment about it.
