As a belated recognition of Exploration Day, here's Charles C. Mann's piece on the history of the Americas before Columbus: 1491. This piece blew my doors off when I first read it.
Before it became the New World, the Western Hemisphere was vastly more populous and sophisticated than has been thought-an altogether more salubrious place to live at the time than, say, Europe. New evidence of both the extent of the population and its agricultural advancement leads to a remarkable conjecture: the Amazon rain forest may be largely a human artifact.
This article spawned a book of the same name, which is one of my favorite non-fiction reads of the past decade.
A group of citizens is attempting to change Columbus Day to Exploration Day. Columbus Day has always been a weird holiday, what with CC's slavery and genocide and all, so this seems like a good idea to me. Maggie Koerth-Baker makes the case over at Boing Boing.
The logic is quite neat. Columbus Day is about one guy and the (actually untrue) claim that he was the first person to discover America. Inherently, that's pretty Euro-centric, which is a big part of why it sits awkwardly in a pluralistic country. But exploration is inclusive. The ancestors of Native Hawaiians were explorers who crossed the ocean. The ancestors of Native Americans explored their way across the Bering land bridge and then explored two whole continents. If you look at the history of America, you can see a history of exploration done by many different people, from many different backgrounds. Sometimes we're talking about literal, physical exploration. Other times, the exploring is done in a lab. Or in space. But the point is clear: This country was built on explorers. And it needs explorers for the future.
