Portrait of David Urquhart David Urquhart,  The pillars of Hercules (1850)

“ The types which I found in nature or in practice are of the stalactitic, dome, and arch,—the horseshoe arch, the tracery on the wall, the diversified colouring of that tracery, the half-globe dome upon the cube; and these, in fact, are the modifications that the architecture of Judæa received, and by which it has been converted into the Moorish.
On the material the system of architecture depended, and it is wholly different from the classic. The great styles of antiquity depended, not on the adhesion of the stones, but their form and weight, and by science alone they obtained arches.

“ This arcade of heavy columns carrying absurdly disproportionate arches is their only motive, and applied inside between aisles and nave, and outside in successive stories rising one above another. As the masons begin better to understand their art, the span of the arch increases, though a large arch for some time does duty merely as a discharging arch, and has smaller arches beneath and within it. ”
