““Art—at least great art—by its very nature has varying levels, or layers, of meaning. In fact, a masterpiece comes to be considered a masterpiece because we know instinctively, even subconsciously, that there is much more to the work than meets the eye. We don’t love the Mona Lisa because she is beautiful (in fact, in today’s aesthetic, she would be considered plain by many), but because she is mysterious. That is the key to the world’s fascination with her for the last five centuries. We know that there is something else there beneath the surface, beneath that smile, and we can’t quite figure it out.””
