Judy sent me a detail shot and more info. It's pretty interesting! She says:
"Just wanted to give you a follow-up on the church door. The heads represent the 6 bishops of Ljubljana overlooking the body of Christ. The shiny knob is the result of thousands of hands entering the church and "rubbing it shiny". I'm sending a different view to show it a little better. "
Interesting, indeed. You should be able to click the photo and see it larger.
Now I'm going to reveal the practical part of myself. Perhaps it's because I live in Texas where any standing water = mosquitos. Mosquitos that could carry West Nile virus which no one wants. I look at the large vessel in the lower right (an amphora if I'm not mistaken) and the bishops' miters (hats) and I wonder if they were designed in such a way as to not collect water. I can't help myself - I'm spending at least as much time wondering about the water as I am about the story that is being depicted. Does anyone else ever wonder about this sort of thing?
