I am fortunate to own "The Five Keys to the Secret World of Remedios Varo" and it is easily the best book on her and the only one that attempts an interpretation of her paintings. A beautiful book, lavishly illustrated, well bound and printed, and with six informative essays. (Another reviewer has listed the essays and their authors). I'd say if you own this book, the Catalogue Raisonné, and the biography by Janet Kaplan you will own all the books on Remedios Varo worth owning. I wish a more thorough biography would be published giving more information on her life in Mexico. I am amazed at how quickly this book went out of print and how scarce it is. For those seeking the book one suggestion I would have would be to contact the publisher Artes de Mexico. In case you did not know it, this book is actually also an exhibition catalog of sorts, except the exhibition came first and the catalog later. The exhibition was at the Museo de Arte Moderno de México in 2008 and was curated by Tere Arcq. I wish I would have seen it. I was lucky enough to see a retrospective of her art at the American Museum of Women in the Arts in 1999. To see her art in person is a completely different experience than looking at illustrations of it as much of it is built up from the canvas in layers of paint, dust, sand, etc., and has a depth that can not be shown in a book. To me, Remedios Varo is the most important and original 20th Century Mexican painter, which I know is saying a lot. I own many books on the subject particularly like Rivera, Kahlo, O'Gorman and Carrington. There is something about the art of Remedios Varo that goes beyond mere painting. It enters the soul, dreams and other dimensions. Really impossible to describe. Beyond special!
