Actually, it was Washington Irving.There are people in the US who still believe Columbus had to prove to the snooty intellectuals of Europe that the world wasn't flat. THAT little gem comes from a children's book, I think.![]()
And it was basically political mudslinging. Irving's goal was to build up Columbus as a hero of the Enlightenment standing up against the old-guard institutions of church, monarchy, etc., and so he ridiculed and caricatured those institutions by depicting them as so stupid that they'd believe something that no remotely observant or educated person would believe, namely that the Earth was flat.
