A trepanned skull, from Nordisk Familjebok Encyclopedia, found in a very special category on Wikimedia Commons.

Trepanation is a bit of an archaeological mystery, apparently carried out as an elective procedure by prehistoric surgeons – in other words, cavemen knocking holes in each other’s heads for the heck of it. It’s been embraced by certain members of the body modification subculture.
