I've had a DVD from Prometheus Entertainment/History Channel sitting on my desk for a year and a half, and I had almost forgotten why I had it by the time I finally sat down to watch the DVD. The DVD is of the show "Angels & Demons Decoded," which aired on the History Channel on May 10, 2009.
While I was watching a part about Bernini's artwork, I noticed a photo of the 'West Ponente' direction marker in St. Peter's Square very similar to mine at 1:08:12 — this wasn't my photo, but was close enough a match to warrant further inspection.
Towards the end of the documentary, when the narrator was talking of the interaction between faith and science in the Church, I found my image at about 1:28:35:
Whoever did the matte on that image (a) had a lot of patience, and (b) is quite good at it! I don't think I've ever attempted to cut out such an intricate photo.
You can view the original photo on Flickr here: Eucharistic Adoration - Monstrance.
I'm glad I was finally able to sit down and watch the show. I also watched Angels & Demons (the actual movie) on Netflix, and thought it was a heck of a lot better (all around) than The Da Vinci Code. But it's still not a greatly historically-accurate film, in my opinion; like most Hollywood flicks, the director and producers played fast and loose with many theories and historical fact. But I don't let it ruffle my feathers :)
