Arguably the most famous image in the art world, “Mona Lisa” was painted by Renaissance master Leonardo da Vinci (1452-1519) in 1507.  Also known as “La Giaconda” referring to the last name of the model who posed for the painting, it is analyzed for its beauty, technique and style, but it is perhaps most famous for the enigmatic look and smile on Mona Lisa’s face.  Her expression and the meaning behind it have survived for 500 years as one of the greatest mysteries in art history.
