I was reading a National Geographic article about a tomb that was recently discovered beneath a mural in ruins of Bonampak. This was an ancient city of the classical Mayan culture of Central America.
In this article there was a link to a quiz about the ancient Mayan world that proved to be pretty tough. I have read quite alot about ancient civilizations & the Maya in particular, but I missed 8 out of 12 questions- for a 60% on this quiz. >:(
It was very informative, though.
