The académie de peinture et de sculpture was like a big school for artists who wanted to paint and sculpt really well. It was set up a long, long time ago in France by the king to help make sure that all the art looked really, really good.
At this school, the artists learned different techniques like how to draw the human body just right and how to create really cool looking sculptures. They also learned about different art styles like Baroque and Rococo, which are fancy names for different ways of making art look super cool.
The académie de peinture et de sculpture was a really important place for artists to go to because it was known all over the world for being the best school for becoming a really, really talented artist!
