Binky..you're spot on. I have read books about the epidemic that explain that in some places, more than 80% of the town/area died from cholera. Bodies would be left in the streets for the body gatherers to pick up, but there weren't enough of them to keep up. A lot of the times, there would be dogs and other wild animals feeding on the dead bodies. A horrible time in history.
MIca, At a guess I would say the artist made a cast of those hands then used it for a mould. The cowl is probably a real cowl or an old blanket soaked in something like plaster that hardens as they do with papier mache and placed over a wire frame.
I worked here when it was Cranberry Specialty hospital until 1994. Although this website says it closed in 92. We took care of patients who were all on ventilators. One night there was a fire...since there were so few patients at the end, I was the only respiratory therapist that was on that night. The fireman said they were going to have to cut the power, and I said that would be impossible because all of the patients were not able to breathe on their own. The firemen ended up getting some neighbors to help bag all of the patients while they cut the power. I also remember hearing they did all of their autopsys for plymouth county in the basement, and a coworker bringing me down to the mourge to show me the jars with body parts in them. Scared me to death. It's a shame to see the remnants now. A lot of kids have gotten arrested recently for trying to get in. It is extremely unsafe at this point. There's been so much arson you wouldn't even recognize it looking at these photographs. It wasn't the best looking hospital, but it was hands down my favorite job.
Yes, manhole covers on street-level can be lifted with anything resembling a crowbar-like hook and provide access to the catacombs network, if the shaft has rungs. I suppose they can't be sealed up either because they're used by official inspectors, or the police just don't know of their existence.
They're a bit risky though, as popping covers in the middle of a Parisian street can attract a fair amount of tension. I would think most cataphiles use these in the early morning hours, when streets are more desolate... the time of day doesn't matter once you're underground!
Many bones and sculls have been stacked artistically, carefully and neatly - even into pretty patterns; and wonder why these were just dumped like this.
Pretty brave, Motts, and pretty strange also, to be stepping on Human Bones sounding like twigs when they break.
Awesomeness is just The First Word - I M A G I N E Planning AND Building this - some skills! Underground town for/with Bones! Am still flabbergasted by all this.
