Famous quotes containing the words grey and/or gold:

    “On the grey rock of Cashel I suddenly saw
    A Sphinx with woman breast and lion paw,
    A Buddha, hand at rest,
    Hand lifted up that blest;
    And right between these two a girl at play
    That, it may be, had danced her life away....”
    —William Butler Yeats (1865–1939)

    “There is too much sour grapes for my taste in the present American attitude. The time to denounce the bankers was when we were all feeding off their gold plate; not now! At present they have not only my sympathy but my preference. They are the last representatives of our native industries.”
    —Edith Wharton (1862–1937)
