Mona Lisa contains two faces?

Art researcher Silvani Vinceti questioned the artist Leonardo da Vinci who used two models for the painting Mona Lisa, one male and one female.

The Daily Newspaper The Telegraph quoted Vinceti as saying that he used infrared technology to study the work Mona Lisa, or La Joconde, on display at the Louvre museum in Paris. Accordingly, the picture was modeled by two people.

He explained: "I believe this work demonstrates Leonardo da Vinci's long-standing passion for bisexualism. For da Vinci, the perfect beauty of man must be a combination of men and women." .

Vinceti said the first model was a sad, beautiful Mona Lisa face without a smile. The female model that many historians agree on is the face of Lisa Gherardini, the wife of a silk merchant in Florence.

Men, according to Vinceti, seem to be da Vinci's long-time assistant named Gian Giacomo Caprotti (also called Salai or Little Devil). Venceti came to this conclusion by comparing the face in the Mona Lisa with other Caprotti-made paintings - including the famous St. John the Baptist by Leonardo da Vinci.

Vinceti said it was possible to clearly identify the image of Caprotti, especially the forehead, nose and smile in the Mona Lisa.

However, there are also some who oppose Vinceti's hypothesis. Art historian Martin Kemp declares: "Infrared images cannot support that argument. Vinceti's theory is a mess of known things, things that have not been clarified and end with thought. statue".
