The poem
On the sea-shore, smell of iodine, and square as in Sicily, and dancing.
An intellectual that came from the common people, preparing himself to be Rosencrantz. He decides to serve Claudius and therefore spy on Prince Hamlet from the fountain.
All over the world — the prison. At the world's end a certain John plays the piano.
Already darkness, and the end is in sight : Ophelia crying in an empty hut. And Hamlet walks to and fro with white headband, in order to be recognized by the Ghost in the gloom.
