Famous quotes containing the words ringed and/or space:

    “Not ringed but rare, not gilled but polyp-like, having sprung up
    overnight—

    These mushrooms of the gods, resembling human organs uprooted,
    rooted only on the air,”
    —William Jay Smith (b. 1918)

    “The secret ones around a stone
    Their lips withdrawn in meet surprise
    Lie still, being naught but bone
    With naught but space within their eyes....”
    —Allen Tate (1899–1979)
