Experts from a US museum believe it could be one of the oldest examples of advanced surgery. The Museum of Osteology in Oklahoma said the skull is reported to have been that of a man who was injured in battle before undergoing surgery to implant a piece of metal in his head to repair a fracture.
But there was no link to any article so who are these experts? I wasn’t seriously suggesting they had molten metal poured on them, it was just my dumb way of asking for more info.
