Famous quotes containing the words open, game and/or license:

    The Moor is of a free and open nature,
    That thinks men honest that but seem to be so,
    And will as tenderly be led by the nose
    As asses are.
    William Shakespeare (1564–1616)

    The savage soul of game is up at once—
    The pack full-opening various, the shrill horn
    Resounded from the hills, the neighing steed
    Wild for the chase, and the loud hunter’s shout—
    O’er a weak, harmless, flying creature, all
    Mixed in mad tumult and discordant joy.
    James Thomson (1700–1748)

    Nature is mythical and mystical always, and works with the license and extravagance of genius. She has her luxurious and florid style as well as art.
    Henry David Thoreau (1817–1862)
