Leonardo da Vinci's Mona Lisa (also known as the Gioconda) is perhaps the most famous work of art in the world. Believed to be Lisa Gherardini, wife of Francesco del Giocondo, it was painted between 1503-1506 on a poplar panel. Now in the Louvre Museum in Paris, it was purchased by King Francis I of France. The painting's appeal lies in the mysterious expression of its subject, its complex composition and innovative techniques such as sfumato, which avoids sharp contours. “Mona Lisa“ refers to the Italian honorific “Madonna“ meaning “my lady“. This name goes back to the description of Giorgio Vasari. The painting shows a woman similar to the image of the Virgin Mary of the Renaissance, symbolizing the feminine ideal of the era. She sits upright with her arms folded, radiating a reserved demeanor, with a gaze that captivates the audience. Her three-quarter profile echoes late 15th-century styles influenced by Flemish art and Italian artists such as Lorenzo di Credi. Leonardo's innovative use of a spacious landscape background and aerial perspective heightens the painting's mystique. Notably, there are no visible eyebrows or eyelashes on the woman's face, although later studies show that they were originally painted. Over time, various adjustments were made to the picture, including changes in the size and direction of the face. The mysterious landscape and model of the work caused a lot of speculation. Some argue that the landscape was inspired by Chinese art, while research shows parallels with the landscape of the Italian region of Montefeltro. Additionally, research suggests that Mona Lisa's elusive smile may be the result of human visual perception.
