“The sea breaks slowly on the sandy beach... On it architecture stays. And the sea and its waves break with slow, constant, inexorable movements, like a bewitching, continual, eternal melody... And gradually architecture is dematerialized... it turns back into sand... nature... and the sea breaks.” (G.P.)

The staging of the performance, as described above by Pettena and documented by him in its entirety with a film as well as with various images, returned to the theme of the relationship between architecture and nature tackled several times in the works of those years. Never straying far in his thought from architecture, from which all his artistic reflection takes its inspiration, he refers to nature with adjectives like ‘inexorable’ or ‘eternal’ which make it abundantly clear that environmental art, and the fascination of the tools that nature provides him with, are by now a more familiar language for him than architecture, although it has long hung on in the comparison, at least in his intentions.
