On my travels to Cathay, Ian, I have come to believe many things I'd previously doubted. For instance, when I was a boy in Venice, they told me that in Cathay there was a stone that burned. I did not believe, but there is such a stone: I have seen it. And if stone burns, why not a caravan that flies? Birds fly; I have even seen fish that fly. You are asking me to believe that your caravan can defy the passage of the sun? Move not merely from one place to another, but from today into tomorrow, today to yesterday? No Ian, that I cannot believe.
