Mona Lisa
The painting is thought to be a portrait of Lisa Gherardini, the wife of Francesco del Giocondo, and is in oil on a white Lombardy poplar panel. It is believed to have been painted between 1503 and 1506; however, Leonardo may have continued working on it as late as 1517. It was acquired by King Francis I of France and is now the property of the French Republic, on permanent display at the Louvre Museum in Paris since 1797.
The subject's expression, which is frequently described as enigmatic,[4] the monumentality of the composition, the subtle modelling of forms, and the atmospheric illusionism were novel qualities that have contributed to the continuing fascination and study of the work.
