Famous quotes containing the word arch:

    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)

    Prayer is the fair and radiant daughter of all the human virtues, the arch connecting heaven and earth, the sweet companion that is alike the lion and the dove; and prayer will give you the key of heaven. As pure and as bold as innocence, as strong as all things are that are entire and single, this fair and invincible queen rests on the material world; she has taken possession of it; for, like the sun, she casts about it a sphere of light.
    HonorĂ© De Balzac (1799–1850)

    Concord’s little arch does not span all our fate, nor is what transpires under it law for the universe.
    Henry David Thoreau (1817–1862)
