Mona Lisa

The painting is a half-length portrait and depicts a woman whose facial expression is frequently described as enigmatic.[2][3] Others believe that the slight smile is an indication that the subject is hiding a secret. The ambiguity of the subject's expression, the monumentality of the composition, and the subtle modeling of forms and atmospheric illusionism were novel qualities that have contributed to the continuing fascination and study of the work.[1] In 1911, it was stolen and copied; the copies were sold as the genuine painting. It was recovered in 1913.

Leonardo used a pyramid design to place the woman simply and calmly in the space of the painting. Her folded hands form the front corner of the pyramid. Her breast, neck and face glow in the same light that models her hands. The light gives the variety of living surfaces an underlying geometry of spheres and circles. Leonardo referred to a seemingly simple formula for seated female figure: the images of seated Madonna, which were widespread at the time. He effectively modified this formula in order to create the visual impression of distance between the sitter and the observer. The armrest of the chair functions as a dividing element between Mona Lisa and the viewer.
