there is an astonishing rhythm to adriaen brouwer – few painters achieve it. goya and daumier achieve it – rembrandt takes it to another level but brouwer always has this phenomenal movement across the page – particularly in the face.
he was of the genre painters depicting tavern life, poverty & (in this case) dentistry.
i have yet to find a book on him. the wikipedia page is pretty sparse. maybe someone should write one.
more of this sort of thing here.
