The Economist points out some propaganda paintings showing blue skies and sun in Venice:
THE sun always shines in Venice; the sky is always blue. This is how visitors like to remember that most beautiful island city. Not coincidentally, that is how Canaletto most often painted the place. His clients, after all, were Grand Tourists, many of them back home in dark English country houses, worrying about farm rents. They longed for the gorgeous, licentious place their memories turned into paradise.
The fact is that in the 18th century and today, Venice would win the title of bronchitis capital of the world if such a contest existed.
Damn right. I remember Venice as being smelly, wet, rainy, and incredibly overpriced. I saw it once, and I have no desire to go back. It's sunnier at the Venetian in Vegas.
