Arturo Ferrari was an Italian painter active in the late 19th and early 20th centuries.
He spent much of his career painting the streets and buildings of Milan, focusing on the older parts of the city and rendering his subjects with a wonderfully blocky, painterly quality that recalls the pioneering work of the Macchiaioli painters.
Though there isn’t much of Ferrari’s work available on line, some of the images, particularly those on Wikimedia Commons, and this one on Google Art Project, have large versions or detail crops that let you see his fascinating approach.
