[M2.4backL] [M2.4back] 4 1. The Wall is either the Support of the Roof, or it is Add here the wall for effect of Surface: Aesthetic in the enclosure of privacy: Or it excludes Hostility, building where height does not properly admit of detached one of these Functions it must have: It is either shafts, conf p 14. (2) Support or shelter, or defence. In relation to these three functions; a wall is to be considered either as - a. supporting vertical pressure, Function a; Bearing of Vertical Pressure By general b. supporting lateral pressure, whether from an oblique principle: that the best is that which is done with roof - or external violence; c as a veil, only; least material, and it being evident, etc. Now if the function be to support Vertical pressure only; the wall is {of course} best built where the given pressure is supported with the smallest quantity of material. All redundant material is an offence to the eye: Now it is {evident or if not evident,} mathematically demonstrable that the more solidly the materials are arranged, the more weight they will bear: and also {that} the most compact form in which they can be arranged is that of a succession of cylindrical masses. This there- fore is the best possible form in which vertical support can be attained; and every truly noble building that ever was built, or ever will be, consists {and must consist} so far as {concerns} its verticalsuppressures, of some modification of it: It is the Pillar support which has been the source of grace and strength {in the buildings of all great nations}, from the infancy of the world till now and must be, so long as the laws of gravity remain unchanged.
