Florentine artist Leonardo da Vinci painted Mona Lisa (1503-1506, Louvre, Paris) in oil on a wood background. Originally, he portrayed the subject in a loggia with columns on either side, but in the end the artist decided to simplify the content. This painting is remarkable for many things, among them the way that the images are created with tones rather than lines and the impeccable use of chiaroscuro (light and dark).
