Battle Cries

[Dan Diffendale]

"Iuppiter Optimus Maximus resistere atque iterare pugnam iubet" (Livy 1.12)

Now keep in mind that this is what Livy, writing around 27 BC, put into the mouth of Romulus (mythological, but for the sake of argument, 750 BC), that is, 725 years earlier. I'm not saying that you should only use this if you're reenacting Romulus (in fact, that would be far less appropriate), but use with caution. That might be like taking a really great John Wayne line and using it as evidence for 19th century American cavalry commands...

In latin would they really say "the roman empire has no boundries!" I got that from night at the museum.

There's no evidence for that that I know of.
