The Mona Lisa, with her enigmatic smirk and wandering gaze, is probably the most famous painting on the planet.

But there's more to this artwork that meets the eye.

From subtle details to mind-blowing conspiracies, let's investigate some of the best-kept secrets about Da Vinci's masterpiece.

You're listening.

You're listening. You're listening. You're listening. You're listening to be amazed.

Before we get to the crazy hidden secrets of the painting, let's find out why it's so famous.

Leonardo da Vinci created the painting between 1503 and 1507, but it wasn't recognized as an outstanding example of Renaissance artwork until a scandal unfolded centuries later.

The painting was sold to French King Francis I, after Da Vinci's death in 1519 and placed in the Louvre, where it still hangs today.

But in the summer of 1911, a young Italian man named Vincenzo Porterugia,

who was hired by the museum to make protective glass cases,

slipped the painting under his smock and escaped unnoticed,

until officials realized the artwork was missing some 26 hours later.

He intended to return the painting to its Italian homeland,

and the ensuing media frenzy lasted 28 months, including only when the Mona Lisa was

finally apprehended and restored to the Louvre in 1913. 100,000 people showed up to view the

painting in the first two days after its restoration,

and nowadays over 8 million people visit it every year. But very few know just how much mystery this painting holds. Almost anyone can recall the Mona Lisa from memory, with her head turned and

arms crossed coily, but some suggest there's more to this iconic stance than you might think.

Many have speculated that her delicately placed hands might be concealing the fact that she was

pregnant. Although the true identity of Da Vinci's mysterious sitter is hotly debated, the most

well-supported theory is that she was called Lisa Girardini, the wife of Florentine's silk merchant

Francesco del Gio Kondo.
