That's a link to a review of what looks like an interesting book. It's on my "must read" list.
As you know, the Gospel of "Mark" was the first Gospel, if you discount the mysterious "Q". The other Gospels are derivative of Mark. According to this book, many of the accounts of Jesus are plagiarized, even if reversed, from the Iliad, a book that the Greek authors of the Gospels knew well.
Here's a tasty video on the subject: http://www.youtube.com/watch?v=tTJT67kgsfc
I'm not saying this is THE story of the NT, just an interesting thought. What say you?
