Why is mona lisa smiling

In the centuries leading up to the Renaissance, paintings were generally created as idealised images, often religious, to be contemplated and revered.

The Mona Lisa was a real woman who with a smile initiated a dialogue with the viewer that had not existed before; it changed the very nature of the relationship between art and audience. Not as exciting as a code in her clothing , but more useful: the trick of using a question as a clue and a key can be surprisingly useful.

Take one of the queries that has vexed humanity for centuries. What is the meaning of life? Inspiring films, self-help books and clever cartoons have all taken a crack at it, to no avail. So if we consider the question as an endless, fruitless quest, we might reasonably assume that meaning is something we care an awful lot about.

And it is. All these meanings gets instantly arranged in a staggeringly huge personal cosmology of meanings that make up your reality just like in The Matrix. The more they afford you, the more meaning they hold for you.

The train is oddly late. When we look at an object straight on, it appears sharper. When we look at it peripherally, glimpsing it with the corner of our eye, it is a bit blurrier, as if it were farther away.

If you stare directly at the mouth, the retina catches these tiny details and delineations, making her appear not to be smiling.

But if you move your gaze slightly away, to look at her eyes or cheeks or some other part of the painting, you will catch sight of her mouth only peripherally. It will be a bit blurrier. These shadows and the soft sfumato at the edge of her mouth make her lips seem to turn upward into a subtle smile.

The result is a smile that twinkles brighter the less you search for it. Scientists recently found a technical way to describe all of this. They always have a sfumato quality, a veil of mystery.

Leonardo once wrote and performed at the court of Milan a discourse on why painting should be considered the most exalted of all the art forms, more worthy than poetry or sculpture or even the writing of history. One of his arguments was that painters did more than simply depict reality—they also augmented it.

They combined observation with imagination. Using tricks and illusions, painters could enhance reality with cobbled-together creations, such as dragons, monsters, angels with wondrous wings, and landscapes more magical than any that ever existed.

Leonardo believed in basing knowledge on experience, but he also indulged his love of fantasy. He relished the wonders that could be seen by the eye but also those seen only by the imagination. As a result, his mind could dance magically, and sometimes frenetically, back and forth across the smudgy line that separates reality from fantasia. Stand before the Mona Lisa , and the science and the magic and the art all blur together into an augmented reality. While Leonardo worked on it, for most of the last 16 years of his life, it became more than a portrait of an individual.

The Mona Lisa became the most famous painting in the world not just because of hype and happenstance, but because viewers were able to feel an emotional engagement with her. And as this study shows, artists can sometimes manipulate our perception in ways that even they aren't aware of. Leonardo da Vinci had a great scientific mind, but even he couldn't have known the real secret behind the Mona Lisa's smile. The proper understanding of the human visual system was still centuries away.

Still, he knew that he pulled some kind of neat trick; the painting was one of his personal favorites and he gave it to the king of France as a gift. Livingstone's research is based on differences in spatial frequency perception within the eye. Spatial frequency is basically a measure of how detailed an image is.

A good example of spatial frequency is right on your computer. Images on a computer screen are made up of pixels tiny dots of colored light. Pictures with higher spatial frequency in other words, more pixels crammed into every square inch are sharper and more detailed than pictures with lower spatial frequency. The tricky concept here is that different parts of your eye are actually "tuned in" to different spatial frequencies.

Anything you look at has both high and low spatial frequency patterns, layered on top of each other—and what you see depends on how you look at it. To get a sense of this, pick an object in the room, like a picture. Look at it out of the corner of your eye. It's kind of blurry, right? Now look straight at it. In a second experiment the researchers drilled down on the sad images. Using the original as the happiest expression, they presented their subjects with seven intermediate versions of the "Mona Lisa" looking glum, including three from the previous experiment.

In other words, in the presence of other sad image, the participants found all the images sadder overall. The study appears in the journal Scientific Reports.
