I bought this book years ago and read it without realizing it was the companion to a BBC series in 1988. My post on the book is here. When I ran across the latter on Amazon Video on Demand I picked it up and watched it. It wasn't the enthralling story that Byzantium: The Lost Empire was, but then nothing is. I did learn a bit more about the history of the Bible, though - more than I did reading the book, I think.
