Please tell me that you're kidding about Brown's "serious & accurate research". Here's a hint for you. The Minor Doxology, used by Christians since the second century AD, is "Glory to the Father and to the Son and to the Holy Spirit. As it was in the beginning, is now, and always, in all ages of ages. Amen." What's that in Latin? GLORIA Patri, et Filio, et Spiritui Sancto. Sicut erat in principio, et nunc, et semper, et in saecula saeculorum. Amen. Now I think that those Christians who spoke Latin natively knew a bit more about "saeculum" then Dan Brown.
The word on the dollar bill is "seclorum".
Now I know it sort of looks like the word saeculorum, but the word "paper" sort of looks like the word "pauper".
That isn't exactly a trusty translation method.
I'll stick to Dan Brown thanks.
