Last weekend I was reading on Wikipedia about some of the biggest misconceptions in history, and one of them was the Christopher Columbus and Earth round vs. flat discussion. Back then, many people agreed with the round Earth concept, but most of them disagreed with Columbus's assessment about the distance needed to reach India from Europe the other way around (and they were right). Some years ago, I visited the city Palos de la Frontera in Spain, and I had the opportunity to see some replicas of the caravels he used to navigate all the way to America. I remember thinking back then that I was able to understand why there was a rebellion just before they arrived at La Hispaniola. Maybe it’s not so clear in the picture, but they were tiny for such an immense trip.
