There are two things in the painter, the eye and the mind; each of them should aid the other.

Everything in nature takes its form from the sphere, the cone and the cylinder.

There is a logic of colors, and it is with this alone, and not with the logic of the brain, that the painter should conform.

To paint is not to copy the object slavishly, it is to grasp a harmony among many relationships.

My nervous system is enfeebled, only work in oils can sustain me.

Drawing and color are not separate at all; in so far as you paint, you draw. The more color harmonizes, the more exact the drawing becomes. When the color achieves richness, the form attains its fullness also

One had to immerse oneself in one's surroundings and intensely study nature or one's subject to understand how to recreate it.
