If you mean would I rely on measurement done by Eratosthenes 2,000-odd years ago, then no. But subsequent discoveries have shown that he had the right idea.

But subsequent discoveries have shown that he had the right idea.You don't have to believe some 'stupid' flat-earther that the experiment was garbage. I know a lot of people put stock in the words of Neil DeGrasse Tyson on these things. Here he is saying the same thing about it being inconclusive.

He's talking the entire video. It's all him with the exception of the commentary words on the screen. So, yes, that's what he says.
Possibly. We'll know for sure one day.
Wouldn't your second sentence indicate a reliance on Eratosthenes?
And that's kind of the point, they didn't know because the experiment was inconclusive at best. Shoddy is a better word.
Ok, gotcha. I’m not sure I’m getting the idea though - is the writer of the captions saying that as there wasn’t an actual third physical well rather than measured angles of shadow in a hypothetical well, the experiment doesn’t offer any proof?
And yet it remains a favorite go-to point, just like the stupid 'ships over the horizon' thing.
The idea of a disk world with a dome over it seems to come from Sumerian mythology.
There actually are.Are there really that many flat earthers here?
Oh, don’t tell me, you explain it away with that stupid vanishing point thing; which has everything to do with artists’ drawings, and absolutely nothing to do with optics.
Not really. It wasn't just Eratosthenes--it's been the standard view for the last 2000 years, and for more reasons than just that. (Aristotle looking at the stars, etc.) It wasn't proven until the first circumnavigation in the 16th century, but it was certainly a correct supposition.
There was no third well. Only two. Or two sticks, whichever version of the story one wants to go with. Tyson adds the third well then makes assumptions on what it might have concluded had their been one.
But there were only two points of measurement, producing results that either results in a distant sun and curved surface or a close and smaller sun and a flat surface. The experiment proved neither conclusively. Therefore, the Greeks didn't 'know' about a round earth since 200 BC.
You've never actually investigated that point, have you? Might want to give it a shot. Think you'll be surprised.
And Hebrew, Norse, Aztec, Egyptian, Hindu, Mayan, etc...
I don’t think that was the whole basis of it - although can’t the angle be calculated from the first 2 wells/sticks? - Phoenicians sailing around Africa made some surviving commentary on the position of the sun that suggests they may have concluded the earth is round earlier. The experiment in this vid isn’t the basis for knowledge about the shape of the earth, just an early record of someone considering the question. It seems evident that in the ancient Near East people assumed for centuries that the earth was flat, just as they assumed that the extent of the earth was much more limited than we now know it to be. Once sea trade became a major enterprise though navigating by the sun and stars would have led to questions about that belief.
Why does that supposed vanishing point manage to relocate itself to the far distance if I climb to the top of a hill? It ought to be a straightforward exercise in geometry, so explanation please.
Not sure they’re all quite the same - ? The point with the Sumerian precursor is that it is the most directly relevant to later Hebrew cosmogony.
