You must use methods familiar to the times in which you live, otherwise you will not be understood, and you will not live. This languages of another … - Eugène Delacroix

It is one of the saddest things in life that we can never be completely known and understood by any one man. (9 June 1823)

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.

Criticism, like so many other things, keeps to what has been said before and does not get out of the rut. This business of the 'Beautiful' some see it in curved lines, some in straight lines, but all persist in seeing it as a matter of line. I am now looking out of my window and I can see the most lovely countryside; lines just do not come into my head: the lark is singing, the river sparkles with a thousand diamonds, the leaves are whispering; where, I should like to know, are the lines that produce delicious impressions like these? They refuse to see proportion or harmony except between two lines: all else they regard as chaos, and the dividers alone are judge.
