James Ward, The Principles of Ornament
“ Plain spaces as alternations in design, are the oases in the desert, and may be compared to a refreshing silence after a continuous chatter or deafening noise.It is easier to do too much than to know exactly where to stop. Excess of ornament defeats its own end, there is no foil to set it off, and it must be guarded against. The Saracens, by the relative weight of their ornament, have to some extent obviated this objection. To know the value of plainness is to enhance the ornament used. To have this vividly brought home to you, the best Greek architecture should be compared with late Roman. ”
