The Mona Lisa by Leonardo Da Vinci

From my first book:
However an audience incorporates and assimilates information gained from perceiving a work of art, each member of the audience will structure the information in order to create interpretation. The wide scope of interpretation evolves with the audience's perception of the art form, which characterizes the multiple associations within a singular work of art.
For example, the interpretation of Mona Lisa's eyes from each subsequent century since her debut has rested on her ambivalent countenance. Although content remains fixed, the historicity of the audience determines the variety of interpretations of any work of art. (Lakatos 19)
