Latin phrase saying "The die is cast". Attributed to
Julius Caesar. It means that there is no way back now.
In context with Caesar, he used this when he crossed the Rubicon on his way Rome after his conquests to reclaim his power in the Senate and eventually to demigod status in Roman culture.
After he conquered the rampaging hordes of barbarians, he would use his other trademark phrase: "Veni, Vidi, Vici", meaning "I came, I saw, I conquered".
You have to admire his eloquence. Latin is such a compact language.
