Matisse worked on his painting BATHERS BY THE RIVER over the course of 8 years.
Now because of technology you can see the stages in between and how he revised. Take a look here.
Seems like it's a process of distilling. Like writing. Stripping away and stripping away. Someone said writing is revising. The art of simplicity--to eliminate the unnecessary that the necessary make speak.
"Matisse: Radical Invention, 1913-1917" opens at MOMA next week.
