Kublai (Khan) asks Marco (Polo), “When you return to the West, will you repeat to your people the same tales you tell me? “
“I speak and speak,” Marco says, “but the listener retains only the words he is expecting. The description of the world to which you lend a benevolent ear is one thing; the description that will go the rounds of groups of stevedores and gondoliers on the street outside my house the day of my return is another; and yet another, that which I might dictate late in life, if I were taken prisoner by Genoese pirates and put in irons in the same cell with a writer of adventure stories. It is not the voice that commands the story; it is the ear.”
“... And I hear, from your voice, the invisible reasons which make cities live, through which perhaps, once dead, they will come to life again.”
Italo Calvino, Invisible Cities
