Why the physical effort, and then to leave the evidence so clearly on the paintings? Matisse wanted to fight in the war but was rejected because of his influenza. poor eyesight and age. He spoke (or wrote?) about fighting the war in his own way, on his canvases, and so he did, I believe. But who was he fighting against? Not the Tradition, which he loved, but Himself. He fought to paint a different way from how he painted before. All that he upheld, prized, identified with, all that had to be thrown down. In overcoming himself, he became a force that cannot be dismissed.
