Christopher Columbus is born in Genoa

Columbus was born in Genoa in late October 1451, and he spent years selling a bad calculation to anyone who would listen. His estimate of the earth's circumference was wrong and the Portuguese court knew it was wrong, which is why they turned him down. Spain funded him anyway because the upside on a shortcut to Asia was worth the risk on the math. He never reached Asia and he never accepted that he had not. I keep him on this timeline as a person rather than as an event because the personhood is the point. This was not an inevitable force of history. It was a specific man with a specific error and a specific set of investors, and the four hundred years that followed on this island were the compound interest on that transaction.
