How did ancient people know that the earth was round?
In: 37
Most of it was determined the same way the sundial came into existence, object placed and using the sun to calculate positioning, determined that the shadow was not directly above, with movement being non-linear. Wasn’t even that long ago either in relation to history, maybe 500 BC? What made it more obvious was when lunar eclipse happened, and people were like…..AHA! If shadow round, we must be round!
