One of the first things I did when I started my blog was to read, and write about, Galileo Galilei’s (1564-1642) book Dialogo sopra i due massimi sistemi del mondo [Dialogue Concerning the Two Chief World Systems—Ptolemaic and Copernican], published in May 1632.
Thanks for sharing! It's a great but lengthy read. I didn't know stars have a diameter when seen through a telescope, and that it was only discovered in the 19th century that this was an optical illusion.
It'd be wonderful to hear you address the divisive concept of a flat Earth. I happen to fall on the oblate spheroid side of the discussion, but am not an organized, formal, deep scholar as you and those whose works you plumb (and my brighter brothers) are.
Also, others' articles make reference to an Earth with an unevenly distributed, lumpy, "potato-shaped" gravitational field. Do you have any views or historical scholarship on that? (On an oblate tuber, or something?)
This site is riveting, even to one who understands maybe half of, it on a good day.
Been a few years since I read Schachts model and was fully convinced, especially by the geometric forms of it, and it's similarity to the magnetic field lines along the plane of inertia
I’m sure you’re aware of Michael Flynn’s Great Ptolemaic Smackdown:

Thanks for the link. I was not familiar with Flynn's essay. I'll read it carefully.
