Mona Lisa

Leonardo da Vinci painted this portrait between 1503 and 1519, and it has become the most famous painting in the world. The woman in the painting is believed to be Lisa Gherardini, a merchant's wife from Florence, though her identity sparked debate for centuries. What makes her so captivating is that mysterious smile, which seems to change depending on where you look. Da Vinci used a technique called sfumato, blending colors and tones so softly that there are no harsh lines, giving her face an almost dreamlike quality.

The landscape behind her is just as intriguing, with winding paths, a distant bridge, and mountains that seem to exist in another realm entirely. Notice how the horizon line doesn't quite match up on both sides, adding to the painting's subtle strangeness. The work was never delivered to whoever commissioned it. Instead, Leonardo kept it with him for years, continuously refining it until his death. That dedication, combined with the painting's theft from the Louvre in 1911 and subsequent recovery, turned the Mona Lisa into a cultural icon that draws millions of visitors each year.
