Emperor Domitianus
Long believed to be a hoax, recent archaeological discoveries have apparently now verified the actual existence of "Emperor Domitianus," a Roman renegade who ruled Britain, or tried to, back in 271 AD. They have found coins bearing his image, more than one, from multiple locations.
The first one was found over a century ago, and was the only one of its kind. The finding of the second coin from the second site seemingly proves its legitimacy.
It's funny. As with most subjects, when it comes to history, what we don't know always exceeds what we think we know. Gotta love it.
I always find it odd that we humans can be somewhere, do something, and then forget that it ever happened. It should seem that everything we have ever known or done should be recorded somewhere and easily readable. Of course, it isn't true...

Possibly the origin of the Domino Theory, Quite.
I suspect that when we get faster-than-light travel and really good telescopes, we're going to find out lots of interesting and surprising things about our own history.
