Famous quotes containing the word lucifer:

    Now the runaways would run no more and never
    again would their hair be tangled into diamonds,
    never again their shoes worn down to a laugh,
    never the bed falling down into purgatory
    to let them climb in after
    with their Lucifer kicking.
    Anne Sexton (1928–1974)
