Less well off people got slots in the wall that they shared with their family. Poor people were entombed in the floor and were mixed with whatever strangers died around the same time.
When the put bodies in these tombs, they weren't covered or sealed up. They just rotted away in plain view. They did put some oils on them to hold down the smell. At least that's what I think our guide said. He gave the tour in English, but between his mask and accent, I missed a lot of what he said.
I have no clue what this was all about. Maybe it had something to do with an earthquake. Our guide told us about some vial of blood that is usually congealed but liquifies once or twice a year and, when it doesn't liquify, bad things like earthquakes and wars happen.
