Hieronymus Bosch, a Dutch painter known for wild, dreamlike scenes full of surprising creatures.
A giant painting in three panels, showing a peaceful garden, a busy crowd of people, and a darker, spookier world.
Painted around 1505, it folds shut like a cabinet and opens to reveal one of the most imaginative pictures ever made.
Bosch filled every corner with tiny figures and playful details, so you can look for a long time and keep finding new things.
Look for the funny mixed-up creatures, like birds as big as people and fruits used as little houses to play in.
You can see this enormous artwork at the Prado Museum in Madrid, Spain.
Someone once found a little tune painted on the picture, and musicians have played it to hear how it might have sounded.
