Famous quotes containing the word sun:

    As the shade went up
    And the ambulance came crashing through the dust
    Of the new day, the moon and the sun and the stars,
    And the iceberg slowly sank
    In the volcano and the sea ran far away
    Yellow over the hot sand, green as the green trees.
    John Ashbery (b. 1927)
