"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."
