I suspect I could list a bunch of furphies about The Great Wall of China, but the one that I find most amusing is that it can be seen from space.
This is a good furphy because it came to be common knowledge courtesy of a Ripley’s Believe It Or not in 1932. Note that date – somewhat before space travel for us humans.
I grew up learning that The Great Wall could be seen from space. This is kind of odd when you think that people already knew you couldn’t see it by the time I was in school.
Still there is something romantic about the idea of man building things so large that they’d be visible from the moon.
Nowadays you can ‘see’ it, though not that well, from space thanks to photographic technologies, so in a weird way, Ripley’s might eventually be proved right.
