The New Yorker, of all things, has an article on "Decoration Myths." As you can expect, it's very erudite. However useful it may or may not be to you, here:
Start in the Met’s entrance hall, where the massive, banal urns that are routinely filled with bouquets of fresh flowers have been replaced, for now, with Woodmans: cylindrical vases fronted with flat, jaggedly cut out slabs bearing glazed and painted, shattered representations of vase forms. When I was there (the arrangements change, week to week), masses of cherry blossoms, lilies, and subtly accenting blue-green eucalyptus complemented such opulent hues as, in a vase titled “Portugal,” an indigo like an organ chord, at once rumbling and clarion. It’s only décor, but what décor!
