Famous quotes containing the words additional and/or images:

    “Dog. A kind of additional or subsidiary Deity designed to catch the overflow and surplus of the world’s worship.”
    —Ambrose Bierce (1842–1914)

    “What images are these
    That turn dull-eyed away,
    Or shift Time’s filthy load,
    Straighten aged knees,
    Hesitate or stay?
    What heads shake or nod?”
    —William Butler Yeats (1865–1939)
