“One way to sum up the new scholarship is to say that it has begun, at last, to fill in one of the biggest blanks in history: the Western Hemisphere before 1492. It was, in the current view, a thriving, stunning diverse place, a tumult of languages, trade, and culture, a regiin where tens of millions of people loved and hated and worshipped as people do everywhere. Much of this world vanished after Columbus, swept away by disease and subjugation. So thorough was the erasure that within a few generations neither conqueror nor conquered knew that this world had existed. Now, though, it is returning to view. It seems incumbent on us to take a look.”
