The Mysteries of the Crypt of Sansevero

Now, as to the "black legends" surrounding the Prince of Sansevero, there are many, each stranger than the last.  That he was a mysterious figure, multilingual, an inventor of wonders, a Mason, an artist - to these things we can attest, and speak of publicly. 

But as to the darker rumors - the whispers that he experimented on human subjects, could create blood from nothing, and authored a process by which men could be transmuted into marble - of these things we cannot know.  The path of deeper inquiry is open to you, should your -- unusual curiosities provoke you in that direction.  As for us, we shall retreat to safer climes.  Some stones are best left unturned.
