Bianchi was a contemporary of Il Macchiaioli, a proto-impressionist movement centered around Florence. Bianchi seems to have spent his career in the Milan and Venice areas, so while he was surely aware of the Macchiaioli, he wasn't active in the group. But his style of painting strikes me as being in the same spirit.
I don't consider Bianchi to be a great painter. However, he was very good at times, so I find it a shame that he is not well known outside Italy.
"After the Duel," an early painting; one source has it 1866, another as 1868.
Bianchi briefly visited Paris around 1869 and might have returned later, because this rainy scene was done 15 years afterward.
An old part of Milan.
A source has this as from around 1890, but the style suggests that it might be earlier.
Note that in both paintings, the horizon line is tilted down towards the right for some reason.
But here Bianchi gets the horizon as horizontal.
More Macchiaioli than impressionist. Chioggia, by the way, is an interesting port town at the south end of Venice's lagoon.
A casually impressionist portrait sketch.
I like this painting. Freely done, yet tighter where it matters.
