What is the description of the Mona Lisa by Leonardo Da Vinci?

Who is Mona Lisa? It is for a biography on Leonardo Da Vinci?

• I am writing a Biography on Leonardo Da Vinci and I was wondering who is Mona Lisa? Because she is like his most famous painting.

• Answer:

  The true answer is probably, "Nobody really knows". But scholars today accept that it is almost certainly a woman whose name is the title of the painting in the Musée du Louvre in Paris, France with the title "Portrait of Lisa Gherardini, wife of Francesco del Giocondo". "Mona Lisa is named for Lisa del Giocondo, a member of the Gherardini family of Florence and Tuscany and the wife of wealthy Florentine silk merchant Francesco del Giocondo. The painting was commissioned for their new home and to celebrate the birth of their second son, Andrea." Whether it was originally commissioned by him, Leonardo worked on the portrait for years, and carried it with him to France, and worked on it for years after, and kept it himself for the rest of his life as his favorite painting. So,if he did accept the commission, he never delivered it, and spent years completing it. The sitter's identity was ascertained at the University of Heidelberg in 2005 by a library expert who discovered a 1503 margin note written by Agostino Vespucci. Scholars had been of many minds, identifying at least four different paintings as the Mona Lisa and several people as its subject. Leonardo's mother Caterina in a distant memory, Isabella of Naples or Aragon, Cecilia Gallerani, Costanza d'Avalos—who was also called the "merry one" or La Gioconda, Isabella d'Este, Pacifica Brandano or Brandino, Isabela Gualanda, Caterina Sforza, and Leonardo himself had all been named the sitter.] Today the subject's identity is held to be Lisa, which was always the traditional view."
