Of The Thing And Not On It

A branch of a tree, not a picture on a wall. Wright refers to harmony of forms as part of his Organic Architecture. To quote that page:

ORNAMENT is to architecture what efflorescence of a tree or plant is to its structure. Of The Thing And Not On It. Ornament is the character of structure revealed and enhanced. If not well conceived, architecture is destroyed by ornament.
