That is Rich ! Can't tell the difference between a goat and a horse ? Like WOW MAN ! A goat weighs very little compared to an average horse, is way smaller, head is a different size and shape etc...... At least I got good laughs and lulz from that one.
Well, yeah. Look closer at the tapestries. The animal there is really more goat shaped and has the goat features. But the perspective makes it look larger than it should be. That was one of the sources that changed the animal into the mythical creature.
I spent more time on farms and less time analyzing Medieval tapestries when I had the chance as I had scant interest in primitive Medieval art.
