This translation was done by me, a one-and-a-half-year Independent Study Latin student. It is not official; it is not professional. At the same time, it's not online translation engine stuff either. I put a lot of thought into my translations (and often double/triple-checked myself against the dictionary and verb/noun charts all over the place), but I still may have made mistakes.
(I have to say, I was very disappointed in Immediate Music/Globus and their treatment of Latin here. It's like they just pulled stuff straight from the dictionary, fiddled with a few words just to alter the sounds they made, and left it at that.
Preliator is much the same.)
I would like to note a provision under Fair Use for educational purposes. I did this as part of my Latin Final Project for the semester, and I'm sharing it both so that I have a fallback if my file fails to play on my instructor's computer and so that others who enjoy this song/language might be able to see my work and either learn from it or critique it.
