Famous quotes containing the words sound and/or image:
“The spotted hawk swoops by and accuses me, he complains of my gab and my loitering.
I too am not a bit tamed, I too am untranslatable,
I sound my barbaric yawp over the roofs of the world.”
—Walt Whitman (1819–1892)
“An image of its state;
The wings half spread for flight,
The breast thrust out in pride
Whether to play, or to ride
Those winds that clamour of approaching night.”
—William Butler Yeats (1865–1939)
