The title is a little misleading. When I read it, I was expecting at least some translations of the existing document in the British library. Given my reading experience with other monographs and more robust works dealing with manuscripts, it didn't seem an unreasonable assumption.
The author discusses Medieval Muslim Horsemanship in only a passing way. It's really a study of the manuscript itself and the descriptions of what the riders and horses are wearing or carrying, and occasionally what is happening in the various plates.
At 36 pages, a quarter of which are plates, it's obviously not an exhaustive study, but I think it was the author's goal to have other interested students pick up the baton and perhaps do a more thorough study or translation.
Bibliography is short and mostly secondary in nature.
A nice book for the student of classical equestrian studies.
