Perhaps the most famous verse of Fitzgerald's Rubaiyat, and with good reason - it is hard to think of any way in which it could possibly be improved.
That's one of the things I most like about short poems, actually - at their best, they can attain a self-contained, gemlike perfection that longer pieces are hard-pressed to match, and the Rubaiyat definitely take their place among the best of the breed.
The individual rubai are untitled, of course; I've just followed the standard practice of using the first line as the title.(5:5) In the same hour came forth fingers of a man's hand, and wrote over against the candlestick upon the plaister of the wall of the king's palace: and the king saw the part of the hand that wrote.(5:6) Then the king's countenance was changed, and his thoughts troubled him, so that the joints of his loins were loosed, and his knees smote one against another.Quoting sections from the King James Version: (5:1) Belshazzar the king made a great feast to a thousand of his lords, and drank wine before the thousand.(5:2) Belshazzar, whiles he tasted the wine, commanded to bring the golden and silver vessels which his father Nebuchadnezzar had taken out of the temple which was in Jerusalem; that the king, and his princes, his wives, and his concubines, might drink therein.
