Webheart: "Those are monkeys"

If those are monkeys, they appear to have prehensile tails. Only New World monkeys have prehensile tails, and the New World had not been discovered in the 14th century...

A curled tail does not suggest a prehensile tail. But they don’t seem similar to medieval monkey drawings that I’ve seen. Then again, I haven’t seen much in the way of Georgian medieval art, which for all I know could have very separate artistic heritage, given Georgia’s remote-from-the-West location.

Depends on who you ask. :D
