This is a worthwhile article from the BBC. I don’t think it requires any commentary from me.
Perhaps one of the most surprising things in Garwood’s book is her revelation that flat earth theory is a relatively modern phenomenon.
Ms Garwood says it is an “historic fallacy” that everyone from ancient times to the Dark Ages believed the earth to be flat, and were only disabused of this “mad idea” once Christopher Columbus successfully sailed to America without “falling off the edge of the world”.
In fact, people have known since at least the 4th century BC that the earth is round, and the pseudo-scientific conviction that we actually live on a disc didn’t emerge until Victorian times. [my emphasis]
