Famous quotes containing the words clouds and/or wall:

    While fortune smiles, you’ll count your friends by scores;
    If the sky clouds over, you will be alone.
    Ovid (Publius Ovidius Naso)

    Once more unto the breach, dear friends, once more,
    Or close the wall up with our English dead.
    In peace there’s nothing so becomes a man
    As modest stillness and humility,
    But when the blast of war blows in our ears,
    Then imitate the action of the tiger.
    Stiffen the sinews, conjure up the blood,
    Disguise fair nature with hard-favoured rage.
    William Shakespeare (1564–1616)
