"Burnt Umber" is a very unconventional novel for several reasons. First, its protagonists are two unrelated real life twentieth century artists whose work was far overshadowed by that of their contemporaries. Second, in place of normal chapters, this book is composed of microchapters, few longer than three pages. Third, although the story unfolds primarily through narration, some microchapters are epistolary and others are in the form of a screenplay. Finally, neither artist is shown to be larger than life or even to be especially likable.
In spite of (or, more likely, because of) these unusual aspects, "Burnt Umber" succeeds splendidly in evoking the lives and art of Franz Marc and Harold Baer(the real name of the latter artist was Harold Paris). For example, the use of microchapters and of alternative narrative voices creates an impression not unlike that of glass shards: the fragments do not fit neatly together but nonetheless they can be pieced together into a recognizable whole.
At the center of this work are Marc, an early twentieth century co-founder (with Kandinsky) of Der Blaue Reiter school and Baer, a mid-century Berkeley sculptor. We are given a unique entree to the imaginations and to the creative processes of these two artists, who see the world quite differently than the rest of us. To be sure, both artists are self-centered, monomaniacal cads. However, Greene's unsentimental approach lends this work a flinty verisimillitude.
As topping on the cake, this novel introduces the reader to several dusty corners of the twentieth century: Munich on the eve of World War I; the trenches as seen from the German side; and Paris in the late 1940s.
Two criticisms: This book would have benefitted greatly from the inclusion of pictures of the art that these men created. In addition, I sometimes found Greene's imagery and descriptions to be overly redolent and, on the whole, to be less effective than his unadorned narration. Nonetheless, "Burnt Umber" is a remarkable achievement.
