Just a sideline to the notion that Europeans in the 15th century may  have 
believed that the world was flat , in Capt. Joshua Slocum’s “Sailing Alone 
Around the World” he mentions his meeting with President Kruger – the President 
of the Transvaal in South Africa.

 

Upon being presented to the President as one who was on a voyage around the 
world, Slocum discovered that President Kruger firmly believed that the world 
was flat and made a point of “correcting” the matter.

 

This was in 1897!

The idea that Europeans thought the Earth was flat until the 15th century is 
one of the great myths of modern history, apparently invented and perpetuated 
by some 19th century writers.

 

It’s a fascinating story about how it actually made it into history books. I 
have a book somewhere that tells the story.

 

Most historians believe that educated people, from the time of the Greeks, 
always knew the Earth was spherical.

 

Columbus’ problem was that he didn’t believe the ancient Greeks who used the 
horizon to make a pretty good guess about the size of the Earth. He thought it 
was much smaller.

 

An interesting belief that was prevalent, however, was that Antarctica was a 
large, temperate continent with millions of people living there. Some ambitious 
early explorers actually returned and told tall tales about visiting there.

Greeks and Arabs were aware of a round earth back in 400BC. 

After the Greek epicycle fiasco, they probably figured out about the earth 
rotating about the sun.

Given the Arabs early knowledge of navigation, they might well have known this 
also but Europe didn't always have knowledge of their early science; even to 
today.  Their astrolabe seemed to have a lot of info.  I haven't figured out 
anything more than its basic angle measurement.

Staffs and backstaffs predate the sextant for measuring and of course, the 
knotted string/wood dowel also.  Quadrant in Columbus' time.
Europe on board with heliocentric theory about 1500AD; completely abandoned 
flat earth finally around 1500AD, probably some much earlier.

Polynesians were seafarers, would be interesting to know their theory of the 
celestial relationship.

Was the sextant invented before we knew the difference?

Yes, that's common knowledge; but the process of doing celestial navigation 
actually presumes that the earth (or your location on it) is fixed, and the sun 
is doing the moving.

 

Here's one of the more concise books on the topic:

Is it not common knowledge that the sun essentially remains fixed for all
