Se refiere al estilo y movimiento en la literatura y arte italianos que florecieron en Milan entre 1860 y 1870. El estilo está basado en una enérgica rebelión contra los valores y la complacencia de la clase media. Pintores que trabajan en este estilo, como Filippo Carcano, Eugenio Gignous, y Luigi Conconi, enfatizan los contornos suavizados, pincelada abierta, empaste, una fusión evocativa de figura y fondo, y una interacción de colores que ejemplifican el movimiento filosófico de fusión de las artes.
