The Mona Lisa's Smile is Not as Enigmatic as You Think - Apparently.
The Mona Lisa's smile is not a result of Leonardo da Vinci's artistic skill, but rather a clever trick of light and shadow. In fact, the painting was varnished multiple times over the centuries, which has significantly altered its appearance. According to the Louvre Museum, the original varnish applied by da Vinci has largely been stripped away, revealing a more subtle and less enigmatic smile than the one we see today.
