Book excerpt: Pierre Bonnard was a very private painter who confined his subject matter to his wife, his homes, the surrounding countryside, and his self-portraits. This book provides a concise review of Bonnard's life, key works, and the development of his technique, which began with early work done chiefly in tone, then led to gradual color-enrichment and, finally, to the mastery of light suffusion. Author Nicholas Watkins presents the artist not as a sentimental survivor of Impressionism, as he was often labeled, but as a highly demanding formal artist who transformed light into an emotional atmosphere enveloping the surface within which objects exist.
