The Mona Lisa Mystery
Every year, about 6 million people visit the Musée du Louvre in Paris to see Leonardo Da Vinci's famous portrait, Mona Lisa. An oil painting on poplar wood, the portrait was started by Da Vinci in 1503 and took about four years to complete, although he is believed to have continued working on it even after that. For centuries afterward, his talent and ingenuity sparked many debates and a multitude of theories in an effort to uncover the mysteries behind the Mona Lisa. The two biggest mysteries are her identity and the nature of her smile.
Who is Mona Lisa?
Many questions arose over the years as to the true identity of the woman in the portrait. The Italians call her La Gioconda, which means "the lighthearted woman." The French version, La Joconde, carries a similar meaning, provoking many thoughts and theories about the Mona Lisa. Most experts now believe that she is Lisa del Giocondo, the third wife of a wealthy Florentine silk merchant named Francesco del Giocondo.
The title Mona Lisa is discussed in Da Vinci's biography, written and published by Giorgio Vasari in 1550. Vasari identified Lisa del Giocondo as the subject of the painting and pointed out that mona is commonly used in place of the Italian word madonna, which could be translated into English as "madam." Hence, the title Mona Lisa simply means "Madam Lisa." In addition, a note written by an Italian government clerk named Agostino Vespucci in 1503 identified Lisa del Giocondo as the subject of the painting.

Still, some experts believe that Lisa del Giocondo actually was the subject of another painting, leaving the identity of the woman in Mona Lisa in question. One popular theory suggests that she is the Duchess of Milan, Isabella of Aragon. Da Vinci was the family painter for the Duke of Milan for 11 years and could very well have painted the Duchess as the Mona Lisa.

Other researchers have stated that the painting could depict a mistress of Giuliano de' Medici, who reigned in Florence from 1512 to 1516, or various other women. A more recent thought is that it is the feminine version of Da Vinci himself. Digital analysis has revealed that Da Vinci's facial characteristics and those of the woman in the painting are almost perfectly aligned with one another.
