In regards to how people commonly designate separate ages of a civilization, if this way of thinking was applied to the inhabitants of the New World just before the Europeans arrived, in what age would they have been considered? Specifically, what age of the eight eras of history (featured in "History of the World") would author and historian J.M. Roberts consider them in? (Pre-History, First Civilizations, Classical, or Medieval?)
There's always room for discussion, but perhaps this previous topic will answer your inquiry.
