Well, I'm glad I decided to stop and think about my story some more. A big plot hole opened up on me - now plugged. I'll be on a firmer foundation to carry on, as well. The only new words I wrote were notes, but they will surely prove to be some of the more important words regarding this project.
I've also uploaded some more pictures onto my website, of St. Peter's, the Vatican and the Vatican Museum, where every ceiling is something to see.
