There is now evidence that Mona Lisa is not da Vinci's first work of drawing a mysterious smile . According to researchers at Sheffield Hallam University (UK), this painting technique was first used in La Bella Principessa painting (Beautiful Princess).

The new La Bella Principessa in 2012 was confirmed by da Vinci, born before the Mona Lisa in the late 15th century. Mona Lisa himself.

Looking straight into the mouth, it seems that Mona Lisa is pursing her lips, improving sadness or not caring. However, if the eyes were to look at details other than the face and hair, she was smiling.

" The Mona Lisa analysis results reinforce the assumption that the visual illusion effect is also used in the portrait of La Bella Principessa," said Soranzo, who works in Psychology.

"Although it is not possible to explain whether da Vinci intentionally used this technique in the La Bella Principessa, but it can be said that he is a master in visual illusion techniques and deliberately uses it in the Mona Lisa. , Soranzo said. "This is consistent with Leonardo's maxim that, portraits must reflect the 'chaotic mind' of the character."
