Claude Monet, a French Impressionist painter who loved painting the same place over and over in different light.
The tall stone front of a great cathedral in the town of Rouen, glowing with the colors of daytime.
In the 1890s Monet painted this cathedral more than thirty times to show how it looked at different hours and in different weather.
He used thick, rough dabs of paint so the stone almost looks like it is shimmering in the sunlight.
Depending on the hour, the same wall can look golden, blue, or pink, even though the building never changed.
Several of these cathedral paintings hang in the Musee d'Orsay in Paris, and others are in museums around the world.
Monet worked on many canvases at once, switching to a new one each time the light changed.
