Further to what I said above..here's a pic I did a few years ago, using the 'charger' horse. It's not a great pic, I'll admit..but to me, it comes reasonably close to what I envision a Norman Knight circa 1070 could look like. I was (and still am) pretty much a poser nebie when I did this pic..so I know there are lots of errors :)
