The Mona Lisa at the Louvre in Paris attracts more than six million fans each year, prompting the question of the strange power of the painting to attract so many tourists.

The American magazine Readers Digest reviewed the secrets and mysteries about the painting that explains its international fame and unveils the many mysteries related to it:

The first puzzle: the identity of the painting
Over the past century, the magazine reported that the story of the painting was that the Mona Lisa was a noble woman known as Isabella d'Este Marquiza Mantua or Costanza de Avalos, Duchess of Francavilla.

Stare at the strange features, some noticed that they saw the face of a man - perhaps Leonardo da Vinci himself - or the man he had been his assistant for 20 years, or perhaps his beloved Gian Giacomo Caprotti.

Another theory suggests that the picture may have been inspired by reality and that Leonardo worked on it over the years to evolve into an abstract vision of the feminine example. Most experts now agree that the Mona Lisa is the image of Lisa Gerardini del Gocondo - wife of a Florentine silk merchant named Francesco del Gocondo. - (hence the name in Italy and France, the Gyokanda or Jokanda).

It is said that the Mona Lisa accepted to be painted by Leonardo da Vinci in about 1503 when she was about 24 years old, and that she took the position of opposition so that her body away from the angle of view of the viewer and her head forward to represent admiration and is transferred by Leonardo's contemporaries.

The second puzzle: the first hidden characters
Silvano Vincetti, president of the Italian National Committee for Cultural Heritage in 2010, claimed that the Mona Lisa's eyes, such as the letters "L" and "V" (the first two letters of Leonardo da Vinci's name) in the right eye and possibly "C" or "E" or " My "in the left.

The Louvre's response was that the Venetian characters were simply microscopic cracks in the paint.

The third puzzle: the broken background
A closer look at the rear view shows that the right side of the Mona Lisa's head is higher than the left side.

It is hard to imagine how the scene would be consistent as the Mona Lisa looks taller and more upright when a person's gaze deviates to the left compared to when it is on the right.

The fourth puzzle: the charming smile
In 2000, scientists at Harvard University in the United States proposed a neural explanation for the elusive Mona Lisa smile. When the viewer looks at her eyes, the mouth is in the peripheral vision that appears in black and white.
Shadows stand out in the corners of her mouth at the time, making the smile look wider, but that smile diminishes when you look at it directly.

The contrast in her smile, which changes when you look at it from afar, makes the painting look like she's alive and adds to the mystery surrounding her story.

The fifth puzzle: the unknown bridge
The background of the Mona Lisa may seem unrealistic, but it is likely to return to the bridge known by Leonardo, who is said to be Ponte Tuscany, in the province of Tuscany, Italy.However, a researcher claimed in 2011 that it was the Bubio bridge over the flooded river of Tripia in 1472.

Mystery Six: The Da Vinci Mania
Da Vinci painted the painting at successive intervals for more than four years and took it wherever he traveled, but did not sign or date it was necessary until the end of his life in France when it became in the possession of his last patron King François I.

It was not publicly available until 1804 at the beginning of the Louvre, but it did not receive special attention until the mid-19th century, when Leonardo began to be known as one of the great Renaissance artists such as Michelangelo and Raphael.

Mystery VII: Was the Mona Lisa sick?
An Italian doctor examined the swelling around the eyes of the Mona Lisa in 2010 and pointed to high cholesterol in her diet and attributed to other cases such as facial paralysis, deafness and syphilis, and the appearance of satisfaction on her face indicates that she is pregnant.

The dentists also put forward the hypothesis that she has gnashing teeth and said that the line around her upper lip indicates that her front teeth are missing and that there is a slight scar effect on her lip that may indicate that she may be a victim of domestic violence, while analytical psychology sees the Mona Lisa as a prominent representation of the female side hidden in The human.
