I have seen here [in London] a play on Faust, the most diabolic thing imaginable. The Mephistopheles is a masterpiece of caricature and intelligence. It is Goethe's 'Faust', but adapted; the principle features are preserved. They have made it into an opera mixed with comedy and with everything that is most sombre.

Proportion applies to sculpture as to painting; perspective determines the contour; chiaroscuro gives relief through the disposition of lights and shadows in their relationship with the background; color gives the appearance of life.. .The colorists, the men who unite all the phases of painting, have to establish, at once and from the beginning, everything that is proper and essential to their art. They have to mass things in with color, even as the sculptor does with clay, marble or stone; their sketch, like that of the sculptor, must also render proportion, perspective effect, and color.

The landscape [in the painting 'The Bathers', 1853, by Courbet ] is of an extraordinary vigor, but Courbet has done no more than enlarge a study exhibited there, near his large canvas; the conclusion is that the figures [the two bathers in the painting] were put in afterwards and without connection with their surroundings. This brings up the question of harmony between the accessories and the principal object, a thing lacking in the majority of great painters, [15 April 1853]
