I hope this image goes through OK.
It's an Easterling Chariot I did in CAD (It still needs a few things done to it to "finish" it out, like the details on the cross-bar, and I need to re-model the wheel-hubs and bosses).
It's a Light Chariot. I have a Heavy Chariot in the works.
The arched bar in the center of the car of the Chariot is also supposed to hold a couple of large quivers of arrows, for the "crew" (It will be a three man crew. A couple of Archers and a Driver, or an Archer, a guy with a Halberd, and a Driver).
The Heavy Chariot will have a seven or eight man crew. Maybe nine-man.
Both will use the Cataphract horses as the horses pulling it. That's one of the things I need to finish on the cross-bar: rigging and tack that connects the cross bar to the horses, which will connect via the hole in the back of the cataphracts.
