Prophecy can only be fulfilled in history and the only reliable connection is with numbers and colors. Start with a big number like "a thousand years" where they reigned with Christ in Chapter 20 of the Apocalypse. The Byzantine Empire was a Christian empire and it did last a thousand years. Constantinople, the capital, has all the characteristics of Babylon the Great. It has many waters, seven hills, merchants, fallen twice, and can be found no more at all. It is also a mystery. All we need now is to identify the seven heads and ten horns. Daniel will help us do this.
