I am going to have a little fun with your chart. I will respond based on your literal approach to Revelation:
1.) You believe the Vatican is a Great harlot that sits upon many waters.
Last I hear that the Vatican sits on Apostolic Palace in Vatican City somewhere in Rome, 31km from the nearest sea which is one water. Okay!
2.) You said that there were no crowns upon the heads and horns during the first century with first 6 heads represented the six Roman leaders, yet when 7th head as "little horn" show up some 1,800 years later, ALL heads AND the horns suddenly have crowns despite the fact that the first 6 emperors had long died? Okay!
3.) You said that Rome is (or sit upon) seven mountains? Ahem... do you know what is God's definition for the word, mountain, in Scripture? Do you realize that the beast has seven kingdoms? Not literal mountains?
4.) You said that the ten horns will destroy the harlot with Fire? Hold on, do you realize there are something more to the judgement of the harlot? You need to read the Scripture:
Revelation 17:16-17 KJV
[16] And the ten horns which thou sawest upon the beast, these shall hate the harlot, and shall make her desolate and naked, and shall eat her flesh, and burn her with fire.
[17] For God hath put in their hearts to fulfil his will, and to agree, and give their kingdom unto the beast, until the words of God shall be fulfilled.
Now tell me. Exactly who are the Ten Horns? If you think she is Vatican City, then tell us how will the ten horns make her naked? desolate? Her flesh being eaten? And burn with fire? Take your time and explain these biblically!
