Atlas Obscura has the odd and fascinating story of how a Venetian named Nicolò Zeno created an island in the middle of the North Atlantic called Frisland, in an apparent attempt to claim that Venetian explorers had discovered the New World. After it appeared on Zeno’s 1558 map, it persisted on other maps for a century afterward (it was even claimed for England in 1580), and the existence of Frisland itself was not fully debunked for a long time after that. “The answer to Zeno’s enduring success lies not with his works, but with his audience. For centuries, people believed Zeno because they wanted to believe him. That was Zeno’s true stroke of genius. He created a story too tantalizing for people to ignore.”
