Famous quotes containing the word arch:

    Thir dread commander: he above the rest
    In shape and gesture proudly eminent
    Stood like a Towr; his form had yet not lost
    All her Original brightness, nor appear’d
    Less than Arch Angel ruind, and th’ excess
    Of Glory obscur’d: As when the Sun new ris’n
    Looks through the Horizontal misty Air
    Shorn of his Beams, or from behind the Moon
    In dim Eclips disastrous twilight sheds
    On half the Nations, and with fear of change
    Perplexes Monarchs.
    John Milton (1608–1674)
