Pilaster Treatment
As the Pilaster is used structurally in order to give support, so its treatment in interior decoration must conform to architectural requirements, and the decoration should be symmetrical on a central axis and vertical in direction.
When flutes are employed to decorate the pilasters, they should be unequal in number—seven being a favourite number. The flutes may be further decorated by cabling, though this should extend to only one-third of the height. The cabling can be elaborated into a series of husks which may arise from the base or be pendant from the top of the pilaster. In either case the general rule must be observed that the cabling shall occupy only a third of the total height.
