The Town Square

The Town Square
Canaletto's Campo di Rialto in Venice
Marco Polo enters a city: he sees someone in a square living a life or an instant that could be his; he could now be in that man's place, if he had stopped in time, long ago; or if, long ago, at a crossroads, instead of taking one road he had taken the opposite one, and after long wandering he had come to be in the place of that man in the square.

Traveling, you realize that differences are lost: each city takes to resembling all cities...
