Dore Ashton knew Rothko and used this knowledge and access to his work to write this book about him. It is therefore useful material for anyone wishing to understand more about Rothko than his paintings can tell us face to face. Rothko was a difficult and tortured man, and his painting and lifestyle reflect that. Ashton gives a thorough and comprehensive guide to this world and his work, but it can sometimes make for hard reading. Whether this is the fault of the author, or the fact that they had difficult material to work with is hard to say, but although I would recommend it as a useful book, I wouldn't say that it was an engaging book.
