     "The Guitar" by Federico Garcia Lorca

       The weeping of the guitar
       begins.
       The goblets of dawn are
       smashed.
       The weeping of the guitar
       begins.
       Useless
       to silence it.
       Impossible
       to silence it.
       It weeps
       monotonously
       as water weeps
       as the wind weeps
       over snowfields.
       Impossible
       to silence it.
       It weeps for distant
       things.
       Hot southern sands
       yearning for white camellias.
       Weeps arrow without target
       evening without morning
       and the first dead bird
       on the branch.
       Oh, guitar!
       Heart mortally wounded
       by five swords.
