I’m in the process of collecting similar art for a MLP RPG project I’m working on, a campaign rulebook for using D&D 4th edition to roleplay in Equestria. It will be released here for free, of course, but I’m in the process of looking for suitable artwork. I’m not paying anything, but you will be fully credited and linked-to in the document. If this sounds like something you’d be interested in, please contact me.
Well, in the interest of objectivity, and as a Celtic descendant myself–they absolutely collected slaves themselves, and waged war on each other as a literal sport. Actually, the definition of a barbarian is one who lives outside of a settled urbanized culture, and it’s only derogatory because the Mediterranean civilizations used it as such. Further, religion was not at all a real factor in warfare (outside of the evangelizing Zoroastrians) in Europe until the conversion of Rome to Christianity, and would only become more important after the Fall of Rome. In fact, everyone was happy to live and let live with no more than a little cultural posturing, particularly from the Greeks, now and then. You’re looking at things with “revisionist” eyes, which misses a lot of the truth of a time period that looked at things very differently.
You can thank the Greeks and Romans.
