So it can be "metaphoric" Jerusalem but not a "metaphoric descriptor" which describes who the harlot is. The Harlot is ALL FALSE RELIGION of All Time. Now I will rove you to have been in error the whole time.
The Vision
Rev. 17:3 So he carried me away in the spirit into the wilderness: and I saw a woman sit upon a scarlet coloured beast, full of names of blasphemy, having seven heads and ten horns. 4 And the woman was arrayed in purple and scarlet colour, and decked with gold and precious stones and pearls, having a golden cup in her hand full of abominations and filthiness of her fornication:
5 And upon her forehead was a name written, Mystery, Babylon The Great, The Mother Of Harlots And Abominations Of The Earth. 6 And I saw the woman drunken with the blood of the saints, and with the blood of the martyrs of Jesus: and when I saw her, I wondered with great admiration.
So, this woman sits with these 7 Heads and 10 horns, of which we know 5 HAVE FALLEN (do you think 5 hills have fallen? come on) which were Egypt. Assyria, Babylon, Persia, and Greece, she sit with Rome who WAS and another who has NOT YET COME (the one whose 10 kings kill her off, the E.U. forbids all religion save Beast worship). She was dressed Purple and Scarlet, and all one has to do is google purple and scarlet and it will tell you these colors were associated with Religious Orders and Government Royalty. These colors were very, very expensive to create, one came from a seed whose plant only grew in a few places, and the other came from a rare insect smushed up. So, when we see scarlet and purple the clue means Religious orders (FALSE RELIGION) and Governments Royalty.
On her FOREHEAD (street harlots back in the day practiced in the city square, the ones who set them up with a client would tell the to look for so and so, and that name would be on her forehead. So, those THREE NAMES not four, were Babylon the Great, Mother of Harlots & Abominations of the Earth. So, if one is trying to identify the harlot what good is Mystery? It is not a part of the description of the Harlot, the MYSTERY in the vision is God saying I am going to explain this heretofore Mystery/Secret. Then the angels shows John three names that solves the puzzle, as I stated before, its means ALL FALSE RELIGION of All Time.
Verse 6 however proves your understanding to be in error, in full. All the Saints (Jewish Saints) blood were on her hands, and all of the Christian Martyrs blood were also on her filthy hands. Well, all of the blood of God's peoples means in NO WISE can the just be ONE CITY, that just common sense my friend. All God peoples were not murdered in Jerusalem, nor Rome, nor Greece, nor Egypt, some are being killed today in Africa and in Muslim nation by what? A FALSE RELIGION called Islam. God true servants never kill God's holy followers, be they Jews of old or Christians, only those who are of FALSE RELIGION kills the Saints & Martyrs, and that in different and varied places all over the whole world, that's why she sits on MANY WATERS. So, nothing you say fits the scriptures, where do you guys come up wit stuff like this? Other men, or Men's Traditions is all it is.
There were many GREAT CITIES, that means a City of renown, that's all. That is very bad Eschatology my friend. I weigh out all the facts, without pre drawn conclusions.
