Why do people say that the Mona Lisa is Caterina?

Some art historians and researchers suggest that The Mona Lisa may be a portrait of Caterina Sforza, an Italian noblewoman, based on similarities in facial features and historical connections. This theory arises from the fact that Leonardo da vinci had ties to the Sforza family and created the painting during a time when they were influential in Florence. However, the prevailing view is that the painting represents Lisa Gherardini, a Florentine woman, as commissioned by her husband. The debate reflects the complexities and mysteries surrounding the identity of the sitter in this iconic work.
