Diego Velazquez, a great Spanish painter who worked for the king of Spain in the royal palace.
A little princess stands in the middle of a room, surrounded by her helpers, a dog, and the painter himself.
Velazquez painted this in 1656 and even included himself standing at a big canvas, brush in hand.
He painted the light and air so cleverly that the room feels deep and real, as if you could step inside.
Look at the small mirror on the back wall, where the king and queen appear as tiny reflections.
You can see this painting at the Prado Museum in Madrid, one of Spain's most loved treasures.
Many people wonder who the painter is really looking at, which makes the picture feel like a fun puzzle.
