Many of the features in the small metal icons are smooth, from people rubbing them as they worshipped.
I was fascinated by these artworks that combined paintings with detailed metal "covers". Both the paintings and metalwork are so detailed and textured and seeing past the metal to the art beneath is like a little secret.
Here's a different example of a mix of painting and metal. See how the metal pieces on the left above are hinged and sitting slightly above the painting. The painting below also has this interesting mix.
This was something I'd never heard before: That under the cross on which Jesus died were discovered the bones of Adam, the first man. See the detail of the skull and bones at the bottom of the cross.
Loved these wooden monks
Naturally, I was drawn to this colorful plate...
