The letter included this fact that stuck in Eratosthenes' mind, and the fact was that the writer said, at noon on the solstice, when he looked down this deep well, he could see his reflection at the bottom, and he could also see that his head was blocking the sun.
Pismo je uključivalo činjenicu koja se zaglavila u Eratostenovu umu, i činjenica je bila da je pisac rekao da u podne na solsticiji, kad pogleda u svoj duboki bunar, može vidjeti svoj odraz na dnu, i da također  može vidjeti da je njegova glava blokirala sunce.
