The dice are cast...

The phrase you're thinking of is "The die is cast", presumably uttered by Caesar upon crossing the Rubicon. The Latin was provided by fivejedjon already: alea iacta est. It means we've crossed the point of no return.

I don't think Caesar was stamping metal while marching on Rome. But if you have some new information, this might be a revolutionary dissertation in History and Classics.
