Eugène Viollet-le-Duc,
Dictionary of French Architecture from the 11th to 16th Century…
“ There is a Gothic flora which has its laws, its harmony, its reason to exist so to speak, like the natural flora; one finds it in the stringcourses, in the capitals, and especially in these florets of crownings, if visible, being often detached on the sky, whose contour, modelled, the pace, can spoil a monument or give him an attractive aspect. The variety of the florets of the XIII E century is infinite, because, although our buildings of this time are covered with it, one does not know two of them which were carved on the same model. ”
