From Washington Post

Or this manifesto of aesthetic self-identification: “I’m a son of the north: my hues are the hammered gold of autumn, the silver-grey of the undersides of leaves in rainy springtime, the khaki shine of chilly summer beaches and the winter sea’s rough purples, its acid virescence.”

From Project Gutenberg
