Note 87 — Chapter XXVII

The reader must always remember that a cornice, in becoming a capital, must, if not originally bold and deep, have depth added to its profile, in order to reach the just proportion of the lower member of the shaft head; and that therefore the small Greek egg cornices are utterly incapable of becoming capitals till they have totally changed their form and depth. The Renaissance architects, who never obtained hold of a right principle but they made it worse than a wrong one by misapplication, caught the idea of turning the cornice into a capital, but did not comprehend the necessity of the accompanying change of depth. Hence we have pilaster heads formed of small egg cornices, and that meanest of all mean heads of shafts, the coarse Roman Doric profile chopped into a small egg and arrow moulding, both which may be seen disfiguring half the buildings in London.
