Famous quotes containing the word spiral:

    What is art,
    But life upon the larger scale, the higher,
    When, graduating up in a spiral line
    Of still expanding and ascending gyres,
    It pushes toward the intense significance
    Of all things, hungry for the Infinite?
    Art’s life,—and where we live, we suffer and toil.
    Elizabeth Barrett Browning (1806–1861)

    The spiral is a spiritualized circle. In the spiral form, the circle, uncoiled, unwound, has ceased to be vicious; it has been set free.
    Vladimir Nabokov (1899–1977)

    Year after year beheld the silent toil
    That spread his lustrous coil;
    Still as the spiral grew,
    He left the past year’s dwelling for the new,
    Stole with soft step its shining archway through,
    Built up its idle door,
    Stretched in his last-found home, and knew the old no more.
    Oliver Wendell Holmes, Sr. (1809–1894)
