IIRC from visiting Biltmore lots of the rooms were replicas or were the actual rooms disassembled and shipped from Europe and rebuilt on site, I think that pool is a copy of a Roman bath, I am trying to confirm that currently if the pool was based on somewhere else.
I noticed the ropes, tied in loops. I also noticed the rust coloration at the crease in the bottom of the pool near the drains.
This looks like a place where you’d hang game for exsanguination.
You put this with the bound children in the painting, with the lines near their necks, and it was my stomach turning (not my mind) that led me to that particular possible conclusion.
This could be a place where ‘game’ is hung and bled prior to dressing and butchering. I’m getting sick writing these words.
