Two Babylons Or the Papal Worship Proved to Be the Worship of Nimrod and His Wife.
Alexander Hislop 1903

The Two Babylons was an anti-Catholic religious pamphlet produced initially by the Scottish theologian and Protestant Presbyterian Alexander Hislop in 1853. It was later expanded in 1858 and finally published as a book in 1919. Its central theme is its allegation that the Roman Catholic Church is a veiled continuation of the pagan religion of Babylon, the veiled paganism being the product of a millennia old conspiracy.
"Is there one who will venture to deny that, from the foundation to the topmost stone, it is essentially a system of Paganism? What, then, is to be the practical conclusion from all this?"
