Famous quotes containing the word arch:

    Men seem anxious to accomplish an orderly retreat through the centuries, earnestly rebuilding the works behind them, as they are battered down by the encroachments of time; but while they loiter, they and their works both fall prey to the arch enemy.
    Henry David Thoreau (1817–1862)

    Dark accurate plunger down the successive knell
    Of arch on arch, where ogives burst a red
    Reverberance of hail upon the dead
    Thunder like an exploding crucible!
    Allen Tate (1899–1979)

    Concord’s little arch does not span all our fate, nor is what transpires under it law for the universe.
