They certainly left the place looking a mess...!
Yeah, they probably fired the maid or something. Another good reason for using arthroscopic and robotic techniques for exploring these sites is, the Mayans also used a contact poison (the name escapes me for the moment), such that some of the stuff that’s “painted” red will actually kill you in a short time after you, say, steady yourself by placing your hand against a wall. :’) Take that, Doctor Jones.
It’s cinnabar. Oh, and it’s not quite so deadly as that. A good handwashing will generally save ya. ;’) Unless you’ve got a cut on your hand, then it could be bad.
