I figure I would add some links to what I think is some really fabulous poetry composed for some famous works of art. Enjoy!
To H'suan Tsung's "Kittens"
To Henri Rousseau's "The Waterfall"
To Hieronymus Bosch's "Death and the Miser"
To Marc Chagall's "The Juggler"
To Saint Longinus
To Jean Chardin's "House of Cards"
