New Scientist hat ein Interview mit Önder Bilgi, der in der Türkei 4000 Jahre alte Skalpelle und angeschnitzte Schädel gefunden hat. Operation am offenen Gehirn zu Begin der Bronzezeit! Hell yeah!
You have found what appear to be scalpels.
That's right. We have just found two cutting blades made of obsidian, a volcanic glass that forms a sharp edge when it fractures. The obsidian must have been imported from another region as there is no natural source of it in the area. We found the blades next to a circular clay platform that may have been used for religious ceremonies. The blades are double-sided, about 4 centimetres long, and very, very sharp. They would still cut you today.
What makes you think they were used for surgery?
We have found traces of cuts on skulls in a nearby graveyard. Out of around 700 skulls, 14 have these marks. They could only have been cut with a very sharp tool. At this time, 4000 years ago or more, it could only have been an obsidian blade. The cut marks show that a blade was used to make a rectangular opening all the way through the skull. We know that patients lived at least two to three years after the surgery, because the skull has tried to close the wound.
