An early morning mist is lifting as the water-bus begins to trace the serpentine loops of the Grand Canal. Vaporetto Number Five, the public Circolare, is departing on a course that encircles this ancient city. Aboard the Vaporetto, Venice is seen as a stage, a curving marble corridor of palaces and monuments. and then, rounding the canal, the view opens and the perspective of Canaletto is there for you. Like pearls strung along the lagoon, the remains of her vanished role, Rialto, Accademia, San Marco and on, they appear, pass and appear, in the wake of the Circolare, an endless flow of the souvenirs of Venice.
