Leonardo da VinciThe color of the object illuminated partakes of the color of that which illuminates it.
Leonardo da VinciWhen you look at a wall spotted with stains...you may discover a resemblance to various landscapes, beautiful with mountains, rivers, rocks, trees. Or again, you may see battles and figures in action, or strange faces and costumes, and an endless variety of objects which you could reduce to complete and well-drawn figures.
