There was the most sharp but hidden conflict between human and nature in his calm canvas. Some people have criticized Millet colors, but Millet was never a color painter. His art source was from Michelangelo and Poussin, who were never color painters. They focused more on "style" and would sacrifice color without any hesitation in order to shape what they wanted, since the color had too much temptation.
We can imagine such an artist who was so simple like the clay and strongly adhered to his own artistic principles could not get the understanding and love from his fellows. God put him in the wrong place. He was incompatible with the French spirit. Millet was misunderstood by both sides from his friends and enemies. But this farmer in wooden shoes never cared and needed to be understood. What he needed to do was painting.
In later posts, let's talk about Ivan Aivazovsky paintings.
