I must state at the outset: I have not read this book. Thus, I truly have no right to award any stars, so in good conscience I could not award 5 stars although I would very much like to have -- solely on the basis of the Genealogical Chart of characters the book contains.
Those of you who have read even three -- No! even two -- chapters of a "full" translation of "The Tale of Genji," which this is not, must have resorted to making notes and lists of the characters, their various "names" and titles, and their relationships to other charcters. I certainly did, and I started doing so while still in Chapter 1.
It was harrowing work ("Is this the same man as X, but in a different job?", "Does Y have a sister, or just another name?", etc)and prevented me from fully attending to the story itself.
So thank you, Prof Bowring, for this book which I will use, much as a raw Parisian tourist uses his/her tightly grasped guide to the Metro, when I return to my copy of Genji.
