“ In the modern pastiches that one made of the Gothic buildings, it is extremely rare to see gargoyles which bind fortunately to architecture: they or are badly placed, or heavy, or too hails, or soft of form, the poor of invention, without character; they do not have this so remarkable real aspect in the old examples; they are impossible, ridiculous beings often, coarse caricatures deprived of style. Certain limestones of the basin of the Seine, like hard limestone-cliquard, marvelously lent themselves to the sculpture these long pieces of projecting stone on constructions. ”
