Time extracts various values from a painter's work. When these values are exhausted the pictures are forgotten, and the more a picture has to give, the greater it is.
Henri MatisseIf people knew what Matisse, supposedly the painter of happiness, had gone through, the anguish and tragedy he had to overcome to manage to capture that light which has never left him, if people knew all that, they would also realize that this happiness, this light, this dispassionate wisdom which seems to be mine, are sometimes well-deserved, given the severity of my trials.
