Seems to deliver on its promise, to the nth degree, by analyzing every permutation of notable works, the change of angle, addition of boats, etc. I've had a fascination with his one major work, per my notes, but somehow I would have wanted that painting analyzed for its absolute, not comparative merits. If much of the harrowing effect is down to Seurat's development of an innovative colour theory, am not certain the book reveals how that theory works in the specific work, though there was certainly a general discussion. The biographical details were revelatory in showing how meticulous and slightly cold Seurat was as a person and how that might be reflected in his highly structured art. I'd have read it more thoroughly if I hadn't lost it in storage like so many things.
