Rembrandt van Rijn, a famous Dutch painter who lived in Amsterdam long ago and loved painting light and shadow.
A busy group of city guards steps forward together, some carrying flags and drums, ready to march.
Rembrandt finished this huge painting in 1642 for a group of townsmen who each paid to be in it.
He used bright light on a few faces and soft darkness around them, so the scene feels alive and full of movement.
Look for a small girl in a golden dress who seems to glow among the guards, like a bright little light.
You can visit this painting at the Rijksmuseum in Amsterdam, where it hangs in its own special room.
Its name is a little joke, because the painting is really a daytime scene that turned dark from old varnish.
