Sorry to burst your bubble but Islam was not until 600 AD. By then, Christians had so muck it up there was an East and West Empire. Two Popes and two Emperors. The Christians got an in with Constantine, and created the menace of Islam as a backlash against East Orthodox, Iconography. Islam may not depict all these saints to worship, the Icons. Orthodox still does, but for the Catholics it is somewhat toned down. Who else rejects the Icons? Jews. Rome was very, very secular. You could worship it all, or none of it. Change every hour, for luck, consult various oracles, etc. What broke up Rome was the Jew's Cult of the Way of Jesus. They nailed up that guy Peter, the homo, because he was preaching that the women of Rome should renounce sex, and serve his cult. The End of Days claptrap, they still talk about. That is what rotted Rome to me. Superstition over some new GOD. And everything they did to purge it just made it worse. Martyrdom. After a while the Christians became powerful, denounced the Jews and raised hell. Then the Emperor of the East, said, fuck it, I will just use this superstition symbol for my war craft, paint it on the shields. Then he had a guy write up all the old stories of this superstition and call it the....how about the Bible? Worked for the Constantine so it became the State religion. Then Gutenberg, much later, understanding the assault of Islam, and Jews, came up with a way to print the Bible. A Bible was the very first thing printed. That more than anything was the downfall of Rome, I believe. They were ruthless, but had a weakness. The Christians brought in the concept of self-Doubt. Rome fell for the flim-flam, the snake oil of a higher power, seems to me. And the race for mass production of Religion Tech was won by the Bible crowd and here WE are.
