Why is this down voted? I don’t see any obvious inaccuracy. It elaborates nicely on Mugasofer’s point.
Edit: and now it isn’t down voted. I’m still confused why it ever was.
Most obviously, ascribing it to Ptolemy seems like a pretty serious error given Eratosthenes’s famed and remarkably accurate calculation of the diameter of the earth centuries before.
Fair enough. But that’s the type of thing a solitary silent down vote will essentially never communicate.
Indeed. The remark about Ptolemy is even accurate, as far as it goes.
