In watching Marco Polo there are a few things that have come up which I questioned the accuracy of and was hoping you could resolve :
Kahn comments that his father drank until his liver burst. Were they aware of anatomy as such and the impact that things like drinking had on it? I'd expect knowledge of the critical organs like heart or lungs but were they aware of things like liver or kidneys etc?
One character mentions being of the "third sex". I've heard of this in places like Thailand or the Philippines but was that a thing in places like ancient Mongolia? Also how would this " third sex" be defined by them?
Kahn always seems to be drinking a white liquid that appears to be milk. Would that be drank so often as opposed to tea? If so how would they prevent it from spoiling?
If anyone else is watching I'd be open to hearing things you may have noticed as well.
I was just looking into this and I think the white drink was Kefir, a kind of fermented milk popular in Northern and Eastern Europe. Apparently the real Marco Polo recounted trying it in his writings.
