What I thought would be a two-minute google has turned into half an hour of every keyword combination I could think of and still not finding any info on whether there even IS a phenomenon of bodily images impressed on burial shrouds other than the 9999999 articles on the Shroud of Turin, which is supposed to be supernatural adn should not be counted!

WHY CAN I NOT FIND THE INFO

wouldn't the Victorians have been all over this???

I just wanted an academic word for it!

There's a lot of cool stuff about identifying fibers found with remains, decomposition leaving traces in soil, the kind of morbid stuff I know is morbid but still find interesting because they're non-obvious things we humans have managed to figure out about the natural processes we live with

(and to me, knowing is less disturbing than not knowing)

the secret agents reading my search history are going to have a great time today

this is exactly the kind of thing my ma' would have encouraged me to call the reference librarian about

which yes, was pre-internet, but they still exist!

Yeah, I'm 5 frustration points away from trying to contact the Mütter Museum (but would have to try tomorrow when it's open)

Today's search history includes "name of hole in center of gar", followed by "name of hole in center of gear". Two very different mental images. XD;;

(the hole in the center of a gear is its bearing)

Some more fun gear terminology: link

Dear self: this is not the time to learn how to build all historical ballistas in order to know exactly which ones used gear(s) and exactly what the gear(s) did.

"catapult torsion gear"
"catapult ballista axle gear"
"torsion catapult"

yep, fun day.
