To my surprise, I still had my copy of DeMille's original version of The Quest in a 1975 paperback. It has been quite interesting, fun actually, to compare his original with his re-written version.Today's version is substantially revised, most notably by punching up the humor and sarcasm a bit. He also tones down the introspection in this newer version, but not enough for my taste. It still borders more closely to bathos rather than pathos.
As for the plot, it might be well to remember DeMille devised this story well before any of the Indiana Jones movies or any of the similarly themed novels like The DaVinci Code, Katherine Neville's The Eight, and Thomas Gifford's excellent The Assassini. In short, he wrote it before stories about treasure hunting for ancient objects or deciphering medieval mysteries became a cliche.
However, DeMille's best revisions are in his adding more substance to the Kenyan Civil wars, and detail about Coptic Christianity, the Jewish settlements (the Falashas), and the truly barbaric Gallas. He adds depth to my knowledge of the history and culture of Ethiopia that I didn't much pay attention to when I was 25. I greatly enjoy the novels of Richard North Patterson (puhleez, not To be mixed up with the typist, James Patterson) for the same reason.
The most striking distinction between the 1975 version and the 2013 version is the difference of maturity in voice, tone, and plotting. We don't often see an author do a re-write of the same work 40 years later. I wish I had some do-overs in my own personal life. Of course, we would expect a richer voice and more plausible plots from someone who wrote the original work when he was about 32 or 33 years old and is now nearing 70, I think. But that doesn't make it any less interesting in comparison. Heretofore, we've not been able to compare an author's apple to the author's same apple.
In the end, though, I only gave it a 4-star rating because, revisions notwithstanding, there was still a lack of depth to the plot as well as to the characters. It was compelling reading, but not up to my usual expectations of a DeMille novel.
