"The use of the world frame transferred to common language to indicate the relationship between an object and its environmental context gives some idea of the importance of what is commonly referred to as the container with regard to the contained. Just as in the case of a building one notes the harmony with the surrounding landscape or urban framework, so with a painting should one observe how the frame is in tone both with the subject matter of the picture itself and with the surrounding wall, since the frame has the double function of completing the work of art and at the same time harmonizing with the space around it."
