"Annuit Coeptis Novus Ordo Seclorum" is Latin for "Announcing the birth of the New World Order".
Uh, no it isn't.
They are actually two mottos and both are taken from Vergil. "Annuit Coeptis" comes from the Aeneid and means "He favors our (daring) undertakings". In the Aeneid, it referred to Jupiter, but here there is no subject, although many think the 'eye of providence' is the subject.
"Novus Ordo Seclorum" does not mean "New World Order", but "New Order of the Ages". It comes from one of Vergil's Eclogues and relates to a prophecy of a child that comes from the heavens and starts a new order of the ages. This was commonly thought to refer to Christ, which is why Vergil's work has survived better than many Roman literature. The Christians didn't destroy it.
"Novus Ordo Mundi" is "New World Order"
