Royal Persian painting is a type of art where people in Asia paint pictures of important things like animals and people. It's called "Royal Persian" because it comes from a country called Iran, which used to be called Persia a long time ago.
The people who make these paintings use special materials like brushes made of animal hair and pigments made of crushed rocks or minerals. They also use special paper or cloth to paint on.

These paintings are very special because they often tell stories or show important events from long ago. They are also very valuable and people collect them because they are so beautiful and rare.
