> Did Erikson know that there was an entire continent with advanced societies completely seperated from the "old world"? Because that is what Columbus discovered. If knowing it was separate from the Old World is what makes it a discovery, then for all we know Columbus absolutely didn't discover any such thing. He went to his grave convinced he'd found a route to India, which was very much the Old World. Conquered by Alexander and everything; stuff doesn't get much older than that.
