There have been several concave earth books written over the years that I’ve found but as far as I can tell there’s only been two ever written in English. There’s the classic Cellular Cosmogony and a lesser known one called Mechanical Proof the Earth is not a Globe.
I’ve been using deepL to translate Karl Neupert’s Geokosmos, which you can find ln the mega drive collection from this site
The process is slow going but by opening up a pdf in a web browser you get Google’s built in PDF scanning function that lets you click and drag to highlight a page of text then it’s a simple copy and paste in to deepL.
Well it’s almost as simple as that I should say. German doesn’t have a word for word translation into English and after you copy and paste the text, remove all the extra newlines and hyphens, you can translate a page of text in about 30 minutes by clicking on sections and changing grammar from deepL’s drop-down options. Occasionally there isn’t a good option and you have to take the liberty of translating it yourself while maintaining the author’s intent. At 30 minutes a page and 150 pages this book can be translated in 75 hours.
Help me. Take a chapter and let’s split this thing up. There’s at least 4 concave earth books that can be translated in this way and we will have a solid foundation to build a better model on
