Millet, who was based in Paris, shares the grandeur of his contemporaries Claude and Poussin. But we tend to picture their landscapes as calm and still, tinted with Mediterranean light – in short, “classical”. That moderate atmosphere digusted the Victorian critic John Ruskin, who contrasted such milquetoast stuff with the British romanticism of Turner. Here, however, Millet creates an electrifying storm erupting from a calm day, its gold light and black clouds searing against the cool Alps: a scintillating bolt from the blue.
