Famous quotes containing the words grey and/or gold:

    “I’ll walk where my own nature would be leading:
    It vexes me to choose another guide:
    Where the grey flocks in ferny glens are feeding;
    Where the wild wind blows on the mountain-side.”
    —Emily Brontë (1818–1848)

    “That is coupled to foul thraldom.
    But if he had assayed it,
    Then all perquer he should it wit;
    And should think freedom more to prize
    Than all the gold in world that is.”
    —John Barbour (1316?–1395)
