While the preserved remains of mummies are generally found in states of rigor mortis-like petrifaction, incorruptible corpses are pretty pliable. Their skin is supple, even years after their deaths. They appear, for all intents and purposes, to be sleeping or only recently dead. What’s more, these corpses don’t show signs of having been embalmed
This is a quote from a fascinating article about incorruptible corpses, or bodies of religious figures apparently preserved by godly intervention. This article, published on Cogitz.com, is very interesting and presents quite a few pictures and videos about such bodies.
I'd suggest taking a look at the other articles on the website if you have time, they all present weird and macabre stories, which are sure to delight the gothic and the curious.
