Did you know that Genghis (or Jenghis) Khan's tomb is deliberately lost? Those who buried him were all slaughtered upon their return so that the location of the tomb would never be known. And that his epitath is said to read "If I were alive many would not be happy."

I've always wondered how they knew what his epitath said.

Or maybe I'm thinking of Attila, whose name is said not to be pronounced "AH-tilla", but "AT-tilla".

Anyway, it was either these guys or maybe Tamerlane.
