Endofmysteries,
While you research eschatology, one book I recommend is:
"A History of the End of the World: How the Most Controversial Book in the Bible Changed the Course of Western Civilisation", by Jonathan Kirsch.
I suggest that in your research, you include the impact of Emperor Constantine: his acceptance of one form of Christianity as his religion affected Western civilisation even more than has the book of Revelation. Naturally, Emperor Athanasius' action in 381 CE is almost as important. If these guys had not acted in the way they did, you would not have this Christian eschatology to research.
