According to my research there is something behind Mona Lisa's enigmatic smile. The enigmatic smile of Mona Lisa has been the source of inspiration for many and a cause for desperation in others. In 1852, Luc Maspero, a French artist, jumped four floors to his death from a hotel room in Paris. His suicide note explained that he preferred death after years of struggling to understand the mystery behind Mona Lisa's smile. When discussing the mystery behind the smile, art experts often refer to a painting technique called sfumato, which was developed by Da Vinci. In Italian, sfumato means "vanished" or "smoky," implying that the portrait is ambiguous and blurry, leaving its interpretation to the viewer's imagination. This technique uses a subtle blend of tones and colors to produce the illusion of form, depth and volume. Some of the scientist says that its just our vision because the human eye are consists of two regions, the fovea, or central area, and the surrounding peripheral area. They say that the fovea recognizes details and colors and reads fine print, and the peripheral area identifies motion, shadows and black and white. Because when a person looks at the painting, the fovea focuses on her eyes, leaving the peripheral area on her mouth. This is one of the reasons why the painting has remained an enigma to art enthusiasts and perhaps the most famous painting in the world.
Another article that i read says that Mona Lisa is a female version of Leonardo da Vinci. They presumed that Leonardo is homosexual that's why he made himself a female version. They also said that Mona Lisa is a self disguised portrait. Some of the scientists compared Mona Lisa's painting to Leonardo da Vinci's skull. But its still a mystery until now. That's why some scientists spend their whole life solving the mystery behind Da Vinci's painting. Because they believe that Mona Lisa is not just an ordinary painting that Da Vinci did. Because the painting shows some mysterious eyes. smile, hand gestures, the way Mona Lisa sits and the way the painting made. They are really pursuing to unveil the secret behind the painting. Here's a picture of Mona Lisa and Leonardo da Vinci compared.
