Rosalia Lombardo

I watched the documentary from 2009 about Rosalia. She died from pneumonia and all her organs are intact as well as her skeletal structure thanks to Alfredo Salafia's embalming technique(which they discovered). Her coffin was placed in a hermetically sealed glass enclosure with nitrogen gas to prevent decay. It's said that when her eyes open,(because they sometimes do) it reveals a perfectly intact iris. They say it's blue, but I'm not sure.
