I first read this book some 6o years ago. It entranced me then and I re-read it several times. As in all his best books (The Dancing Floor; The Courts of the Morning; The Far Islands; possibly Greenmantle) in Prester John there is a captivating sense of ancient, hidden knowledge ... meretricious, of course, but seductive. There is also clean prose and the bite of a well written thriller. My reason for re-reading it was to see if nowadays its inherent racialist snobbery made it intolerable. Interestingly, it does not. It had no effect on me as a child and, if you feel your way back into the strangely innocent mind-set of the imperialist elite, it is something you may observe with curiosity ... and gain historical understanding. Naturally, the thrill of the story has faded a bit with longer experience and a more jaded palate - but it is still a darn good tale.
