Famous quotes containing the word stain:

    She comes to meet death,
    To stain the altar of the goddess,
    To hold her girl-throat
    Toward the knife-thrust.
    Hilda Doolittle (1886–1961)

    The nightingales are singing near
    The Convent of the Sacred Heart,

    And sang within the bloody wood
    When Agamemnon cried aloud,
    And let their liquid siftings fall
    To stain the stiff dishonored shroud.
    —T.S. (Thomas Stearns)

    There is rust in my mouth,
    the stain of an old kiss.
    Anne Sexton (1928–1974)
