Jan van Eyck, a master painter from the Low Countries who was famous for his amazing, glowing details.
A huge painting made of many panels that fold open like a giant book, full of angels, people, and a peaceful lamb.
Van Eyck and his brother finished this great altarpiece in 1432 for a cathedral, and it is still treasured today.
He used oil paints to show tiny details, from sparkling jewels to single hairs, so everything looks real and shiny.
When the panels are open, you can count many green plants and flowers, each one painted like a real garden.
You can see it in Saint Bavo's Cathedral in the city of Ghent, in Belgium, where it has stayed for centuries.
This painting has quite an adventure story, as it was stolen and hidden many times but always came back home.
