One of the most famous paintings in the whole world is the Mona Lisa.
It was painted by Leonardo Da Vinci, one of the most famous artists of all time.
It might seem like just a nice painting of a woman, but there were many reasons why people liked it so much.
You might notice in the painting that the woman is sitting in front of what looks like a sky and mountains.
She wasn't really sitting in front of that place, Da Vinci drew the background from his imagination.
In the time when Da Vinci was living, people usually only painted pictures of real places they had in front of them.
To paint an imaginary place without something to look at was a very big deal!
Da Vinci painted the woman's face and hands to look very bright compared to her hair and outfit.
When something bright is put up against something dark it is called contrast, and artists sometimes use it to help things stand out more.
The painting also has very dark lines around the woman's hair and body, and the background looks fuzzy and has lighter colors.
This helps make the woman look more important in the picture, and makes the background look far away.
The Mona Lisa also has very good perspective.
That means it looks ike the woman's arms are in front of her body and the painting is behind her.
Even though it is a flat painting, it looks almost like a real person was sitting there.
These days we have 3D movies to go see, but in those days making a painting that looked real was the closest thing they had to 3D.
Da Vinci made this painting about 500 years ago, and even to this day it is one of the most well liked paintings in the world.
