Analysis of Summer Holiday

When the sun shouts and people abound
One thinks there were the ages of stone and the age of
     bronze
And the iron age; iron the unstable metal;
Steel made of iron, unstable as his mother; the tow-
     ered-up cities
Will be stains of rust on mounds of plaster.
Roots will not pierce the heaps for a time, kind rains
     will cure them,
Then nothing will remain of the iron age
And all these people but a thigh-bone or so, a poem
Stuck in the world's thought, splinters of glass
In the rubbish dumps, a concrete dam far off in the
     mountain...
