I saw a documentary when I was very young (in the early 80s) about the Mount of Olives, talking about how people so wanted to be buried there that they had to create catacombs underneath. But even those were pretty full, and the filmmakers walked through the catacombs filming some of the bodies. I remember that there was a shot of a corpse with a crown on her head, and they said that there was more than one and the crown indicated something.
I’m not sure we had cable at the time. It may have been a Nova thing, and it’s quite likely it was on PBS.
