Why not trying the bible. Its an astrotheological piece of writing made about people worshiping the sun.
I have to ask, have you read the Bible? Because I have, and what the text lacks is sun worship. I've seen arguments wherein people suggest that the Bible implies sun worship following the ancient Egyptian cult, but these arguments do not account for the history of the text's development. Those arguments, that I have seen anyway, are comparable to conspiracy theories about world government.
Yeah there's a lot of things about the bible you could say. But I will probably not read too deeply into the Bible.
Regardless of your religious beliefs, or lack thereof, the Bible is one of the most influential texts available to mankind. People should read the Bible just as people should read Homer.
