Note 52 — Chapter I · THE CONTRIBUTION OF THE ANCIENT WORLD
Reading edition
See Thalamas, Géogr. d’Ératosthène, 1921, pp. 162–163. Konrad Miller, Erdmessung, 1919, pp. 5–6, argued that Eratosthenes calculated the circumference at 252,000 stades, not 250,000. Even if, as Cleomedes tells us, he calculated it at 250,000 stades, it seems probable that it was Eratosthenes himself and not some later scientist who arbitrarily raised it to 252,000 in order to obtain a figure divisible by 60 or perhaps by 360.
