It has been stated that the pillars are placed in the centreof the meeting of four cross arches ; therefore, as shown inseveral preceding cases, they stand firm. They, however, pos-sess other advantages, with respect to their stability, by beingsquare, and placed with their diagonal line against the outwardthrust of the arches ; in consequence of which their stability isincreased equal to one fourth of their height.
