Hi,
I think there is an error in the verse that you provided, because I'm greek and as far as I know, there is no such word as "παχτων". Most probably it should be "πάντων". In that case the translation would be:
Because Triballus takes down together with himself his own (people/soldiers) most of all (enemies).
By the way, this verse is not 14th century, but most probably ancient script before Christ ;-)
However, I do speak ancient greek, and I'm an American College graduate, so my english is pretty good as well. Moreover, I love history ;-)
Thanks for looking at my bid.
