Not "big" - they'd probably have ridden something more like Norwegian Fjord or the Gotland - I mean, were the Vikings known for their cavalry?
Or the Icelandic Horse - which claims to be the only true Viking horse.
Were the horses in the movie Icelandic horses?
I've seen Fjord horses, which are neat and yes, big pony-sized. (And have crests instead of manes, IIRC). I'm probably thinking of later-developed Belgians and whatnot as coldbloods.
Cute Icelandic horses -- trying to imagine fully armored type people riding these guys. But the armor from that era isn't the same as the later knights with the Great Horses, right?
Cute Fjord Horse pics with the crest and the stripe down the back onto the tail, too.
Picturing Karl Urban riding one of those horses, wearing, for example, his Rohirrim armor from Lotr is amusing.
I'll stop now. But Fjord foals are the cutest thing EVAR. Now I
really really
want a pony.
They just got a Fjord up at the barn (his name is Finn, and I made a lot of Dead Parrto jokes). He's damn cool-looking. Kinda short and squat, with a giant heat. And his mane is light with a black stripe down the middle, all the way down the length of his neck.
If this was the inspiration for Pathfinder, they're obviously planning on using this for the sequel.
