The Book of Revelations plays heavily on reversing the various elements of the story of Eden. For example, every snake would be thrown out of Eden, according to the book of Revelations. The book interprets the snake curse in Genesis, offering us the so famous, and so uniquely Christian, snake burning option. According to Revelations, the way you deal with that problem of having a snake up the tree in Eden is that you just burn the snake. Problem solved.
If you were looking for that snake in those days it would be found ‘outside' to use the terminology of Revelations, and this represents another of the reversals of Genesis found in the book, in that ‘outside' is a parallel to the place where Adam and Eve found themselves. In Revelations, Adam and Eve, after undergoing terrible ordeals, symbolized in this book by the worst of all systems, the inhumane, expansionist, totalitarian tyrant state, well, after going through hell on earth, which people do when things that evil happen to them, Adam and Eve finally made it back to Eden, only to find that rather than going into agriculture as before, they were going to find a castle waiting for them, while the snake did that thing of going ‘outside', which in Revelations, is where snakes can wait for snake burning time.
You can understand how the book of Revelations would have to be the least favorite book for a snake, or for a tyrant and his friends in a tyrant state, given the way they have to read through the end of that thing and get to that terrible sounding stuff about waiting outside for snake burning time, not likely to be the most pleasant or well liked reading material by any snake I am sure. Those snakes must be reading something else, because this book wouldn't offer them much in the way of lifting their spirits or giving them any encouragement whatsoever, what with the author being so horribly ruthless in implementing that snake burning policy.
