Famous quotes containing the words dark and/or horse:

    “O Rose, thou art sick!
    The invisible worm
    That flies in the night,
    In the howling storm,
    Has found out thy bed
    Of crimson joy:
    And his dark secret love
    Does thy life destroy.”
    —William Blake (1757–1827)

    “The horse stares at its captor, barely remembering the free kicks of youth.”
    —Mason Cooley (b. 1927)
