@TheVulgarTongue@histodons This is fascinating. I recently read Marcus Rediker on pirates and he mentions that the skeleton on many jolly Roger flags was called "an anatomy" but doesn't go into detail.
That's helped me find it with a double T: “The vulgar word for a skeleton.” and also a verb:
“ To be ottomised; to be dissected. You'll be scragged, ottomised, and grin in a glass case: you'll be hanged, anatomised, and your skeleton kept in a glass case at Surgeons' Hall.’
