The works must be conceived with fire in the soul but executed with clinical coolness.

Little by little, I've reached the stage of using only a small number of forms and colors. It's not the first time that painting has been done with a very narrow range of colors. The frescoes of the tenth century are painted like this. For me, they are magnificent things.

Never, never do I set to work on a canvas in the state it comes in from the shop. I provoke accidents - a form, a splotch of color. Any accident is good enough. I let the matiere decide. Then I prepare a ground by, for example, wiping my brushes on the canvas. Letting fall some drops of turpentine on it would do just as well. If I want to make a drawing I crumple the sheet of paper or I wet it; the flowing water traces a line and this line may suggest what is to come next.

What I am looking for... is an immobile movement, something which would be the equivalent of what is called the eloquence of silence, or what St. John of the Cross, I think it was, described with the term 'mute music'.

More important than a work of art itself is what it will sow. Art can die, a painting can disappear. What counts is the seed.

I feel the need of attaining the maximum of intensity with the minimum of means. It is this which has led me to give my painting a character of even greater bareness.

I begin painting and as I paint the picture begins to assert itself, or suggest itself, under my brush. The form becomes a sign for a woman or a bird as I work... The first stage is free, unconscious... the second stage is carefully calculated.
