I've read old textbooks on the subject while doing research on the development of the theory of plate tectonics. Your claims about TPTB is simply a
rubbish claim to gloss over your failed research.

I still don't see how a map with such major mistakes such as the location of Zanzibar, which should have been well known at the time, can be trusted to any degree to show that there was a southern continent.
The Magellan expedition of 1519-1522 should have encountered the southern continent if it had its claimed position. No such land was found.

I am curious if you can tell us how you created your maps, how you alter the images or remap the images of the maps to show your overlays. I see differences between the old map and your reconstructions you use in overlays.
So here is my point; Can you tell by looking at the two renderings above of the southern continent that they are virtually the same design? For some it could prove a bit difficult. Obviously it would be much easier if we viewed both designs rendered to the same type of projection.
It's not really possible for someone to do better than guess that they are the same. I see similarities, but they may be very different projections making it difficult to claim that they are the same.
Like I said before, there are some striking errors in the map such as the location of Zanzibar and the fact that Magellan's voyage should have sailed through the continent as indicated on the map.
Also, I see some differences between the map and the reconstruction you have produced. You seem to have done much more than simply remap coordinates since the maps would not overlay. You have changed the size of the continent indicated on the old map.
I thought that was fairly clear. By the time of Magellan's voyage it should have been clear that no southern continent as large as the one on the map could exist.
So now we are at the meat of the matter. How did you come up with your version of the Fine map of a southern continent? Did you do this by hand?
And how did you do this step [resize both modern Antarctica and Finé’s Antarctica to similar sizes]?
Did you do this by trial and error? Did you do this by hand?
I've done lots of projections...
Look at the voyage map. In the middle of the Indian Ocean Magellan is as far south as the Cape of Good Hope. The Fine map shows Antarctica well north of that point.
Was it linear? What sort of scaling did you use?
What sort of data do you have? What program did you use? Can you share the data??
