Rowbotham's work on the topic is still much more detailed and systematic than any other studies so far.
But...he was wrong, wasn't he?
He's wrong about perspective, that isn't how perspective works at all.
He was wrong about the moon - he said it was translucent for goodness sake, and he said it emits its own light which it demonstrably doesn't.
He was wrong about pretty much everything, his ideas were not accepted by any serious scientists and he has been largely forgotten about by history.
I'd never heard of him till I found this place.
And his motivation for his book is clearly a misguided interpretation of Scripture.
He was not a man of science, he never worked professionally in a science relevant to his writings, I don't believe he has any published peer reviewed papers.
He is not an authority. If he is who your basing your beliefs on then you're in trouble.
