You're welcomed! ^_^
Just thought I should add one more thing --> Okay, let's say the horse is real. How come the legs (esp. the left foreleg) and tail are covered? It doesn't make sense to cover up the horse like that and have it trot through a crowd with a rider on its back. It's dangerous because the legs could get tangled in the sheet and the animal could fall down and injure itself. Plus, the rider could also be seriously wounded from such a fall. If the animal is real, it could be the rider is taking a big safety risk as he parades around on the horse. Hmm...
Regarding the long "skirts" shown on the horses, they were known as caparisons, and they were worn over the "barding" (metal horse armor), probably as a way to display a knight's "colors" (heraldry). Below is a quote from wiki. Tip-to-tail and all the way to the ground was apparently not out-of-the-ordinary.
"Barding was often used in conjunction with cloth covers known as caparisons. These coverings sometimes covered the entire horse from nose to tail and extended to the ground. It is unclear from period illustrations how much metal defensive covering was used in conjunction. Textile covers may also be called barding."
