Canaletto's Views of Venice

The Rio dei Mendicanti, 1723-24, by Canaletto, Ca' Rezzonico, Venice
Given the number of paintings of his native city that Canaletto (1697-1768) churned out during his long career as the premier vedutista of his day, it comes as a surprise to many people to discover that only two of his views of Venice are on public display in the city. 
The Grand Canal, 1723-24, by Canaletto, Ca' Rezzonico, Venice
The two paintings are to be found in the Ca'Rezzonico. They are both early works and exceptionally fine examples of his art. 
The Rio dei Mendicanti (detail) by Canaletto, Ca' Rezzonico, Venice
My favourite of the two is The Rio Mendicanti and, as I was looking at it the other day, I noticed for the first time the detail of the man in the bottom left corner. Given what he is up to, there clearly wasn't a pissotta next to the church.
