I think there should be a research thread to compile all of the... well... research. Let's start with static heads for all civs. Here are a couple which could be LH's for Armenia.

Rex Armeniae Levon (Leo) II who was crowned king of the Armenians by the Holy Roman Empire. (Note that he is king of Armenian Cilicia)

King Gagik I Bagratuni, the lost statue, I don't really like this one, but he was a great king of Armenia Proper and not Armenian Cilicia.

I'll see what I can come up with for other civs.

Well, here's a nice image I cut down to be used as a LH for Basil II Bulgaroktonos.

Here is a nice Krum of Bulgaria:

Since I haven't been able to find a Batu Khan, does anyone think using a picture Ogodei Khan (they were both grandsons of Genghis) would be acceptable?

fine, i dont think many people can tell the difference

Caliph Abderraman III, unfortunately the largest picture I could find.

Also, maybe research could also included finding nice pictures that could be used for UU's and maybe more accurate Medieval units? For example, here are a few:

Armenian Late period Heavy Infantry

Armenian Heavy Sepuh Cavalry

Armenian Archers and medium cavalry

Now if we could find some good pictures for other faction's units...;)

Okay, the ones that I really need are Widukind, Umar, and Ashot. If anyone can find these guys or guys that are similar, please post them.

Ashot I Bagratuni

Here ya go. The only picture I could find, it is a modern representation.

Thanks! I couldn't find any pictures of Ashot!
