Canaletto's views of Venice: not only a matter or art.
Canaletto is the view painter par excellence, known all over the world for his Venice and Grand Canal's views. But the great value of his paintings isn't only a matter of art. In the last few years they have proved to be fundamental in analyzing Venice's sea level, as "acqua alta" is a pressing problem in the lagoon.

Photographs before photography
Canaletto used 'camera obscura' technique to fully create photographic paintings. In fact, his reproductions of Venice are so accurate they can be used as scientific evidence—photographs before photography was even invented.

A tour among the ancient canals
Publication of the prints put Canaletto’s paintings in a fixed sequence. The inimitable experience of fluidity gliding along the Canal may even have suggested the arrangement that appears in Canaletto’s paintings. No earlier published set of printed views provides a similar re-creation of the sequential spacing experience of moving through an urban setting.
We could even see this arrangement as a precursor of modern Google Street View.
Street View ahead of time
Canaletto’s paintings offer a sequential trip up and down the Grand Canal that starts at, and then returns to, Rialto.
Visit Venice like a tourist of the past
This arrangement was adopted because, when visitors first came to Venice, they often began exploring it from that point. Such was the case with Johann Wolfgang von Goethe, who visited in 1786.

The secrets hidden in the artworks
By looking at the algae belt on buildings facing the Grand Canal in his paintings, Italian researchers Dario Camuffo and Giovanni Sturaro collected a huge amount of previously unknown data.
The sea level
They have been able to understand how the sea level has changed over the last three centuries.
Natural changes and human impact
The comparison of the data from the ancient paintings with those gathered today through much more modern techniques (such as satellite derived measurements) is of invaluable help to distinguish between natural and human impact on subsidence and other phenomena.
A city at the forefront
Venice is the symbol of the critical sea level rise, an issue being faced by many cities and countries around the world. Historically, the city has always been at the forefront in addressing the matter and finding new ways of understanding it and challenging it.
Fighting the climate change
Even today, Italian researchers and engineers are inspiring the international community in the common defense against the consequences of climate change.
