The Salt Man

http://commons.wikimedia.org/wiki/File:Saltman1.jpg

In winter 1993 workers in a salt mine in western Iran uncovered the body of a man with long hair and a beard. He had been buried in the middle of a 45-meter tunnel.

Carbon dating showed he had been lying there for 1700 years. It appears he was of high rank and had been struck in the head, but no one knows who he was or how he came to be there.
