On God and Art- Marc Chagall Quote:

“When I am finishing a picture, I hold some God-made object up to it – a rock, a flower, the branch of a tree or my hand – as a final test. If the painting stands up beside a thing man cannot make, the painting is authentic. If there’s a clash between the two, it’s bad art.”
