Apparently miners in South Africa have been finding strange metal spheres with grooves etched around them... The kicker is that the layers they've been found in are Precambian -- billions of years old!

That would be the Antikythera mechanism. There are mentions of similar devices in records originating from that period, so while rare, it wasn't necessarily unique. Mostly it means that the ancient Greeks were better at clockwork than we'd been assuming (clockwork was known, but most mechanisms weren't this sophisticated).

That'd be my thought too-- not enough to say 'omg time travelling Victorians visited ancient Greece' for me. };)

Yes, that was it, thank you for the link.

And Lynx, I also remember something about electroplating via small jars of some sort from ancient Babylon.
