Famous quotes containing the words counterfeit and/or pen:

    I can counterfeit the deep tragedian,
    Speak, and look back, and pry on every side,
    Tremble and start at wagging of a straw,
    Intending deep suspicion. Ghastly looks
    Are at my service like enforced smiles,
    And both are ready in their offices
    At any time to grace my stratagems.
    William Shakespeare (1564–1616)

    To give an accurate and exhaustive account of that period would need a far less brilliant pen than mine.
    Max Beerbohm (1872–1956)
