I was doing research and came across this. I think these could be the 4 words on the rings:
PIA
EROS
PHILO
AGAPE
I don't know, but if they used history to come up with the four words, I'm guessing these are it.

well give us a link so we no you didnt make it up

i doubt those are the words

I think they are, but they might change them, I don't know.

Somone correct me if I am wrong, but I believe those words are Greek. All indications are that these rings are Sumerian in origin (or, perhaps from a higher power?). We have had small clues/hints in Sumerian (latinized, of course), which further the notion of the words being Sumerian. Now, what would words that can be translated into "Love" have to do with denying ignorance? Those do not sound like "words of truth" to me.

Regardless, we shall soon learn the first word, and begin the sequence to unlocking the voice against ignorance!
