The Shield of Achilles

   

 She looked over his shoulder
       For vines and olive trees,
    Marble well-governed cities
       And ships upon untamed seas,
    But there on the shining metal
       His hands had put instead
    An artificial wilderness
       And a sky like lead.

A plain without a feature, bare and brown,
   No blade of grass, no sign of neighborhood,
Nothing to eat and nowhere to sit down,
   Yet, congregated on its blankness, stood
   An unintelligible multitude,
A million eyes, a million boots in line, 
Without expression, waiting for a sign.
