Famous quotes containing the words ray and/or casting:

    I paint what cannot be photographed, that which comes from the imagination or from dreams, or from an unconscious drive. I photograph the things that I do not wish to paint, the things which already have an existence.
    —Man Ray (1890–1976)

    All we know
    Is that we are a little early, that
    Today has that special, lapidary
    Todayness that the sunlight reproduces
    Faithfully in casting twig-shadows on blithe
    Sidewalks. No previous day would have been like this.
    John Ashbery (b. 1927)
