Revelation 13:18 Here is wisdom. Let him that hath understanding count the number of the beast: for it is the number of a man; and his number is Six hundred threescore and six.
Revelation 18:16 And saying, Alas, alas, that great city, that was clothed in fine linen, and purple, and scarlet, and decked with gold, and precious stones, and pearls!
Revelation 18:24 And in her was found the blood of prophets, and of saints, and of all that were slain upon the earth.
What comes to me is this is apocalyptic material. Apocalyptic writing was common in the 2nd BC- 100ad. Highly figurative-highly debatable as what those images mean- not to be taken literal . Numbers highly symbolic. Suggest you read “the Rapture Trap” Apocalypse: Definitions and Related Terms

Preliminary Description of “Apocalypse”:
In popular terminology today, an “apocalypse” is a catastrophic event (e.g., nuclear holocaust).
In biblical terminology, an “apocalypse” is not an event, but a “revelation” that is recorded in written form:
it is a piece of crisis literature that “reveals” truths about the past, present, and/or future in highly symbolic terms;
the revelation often comes in dreams or visions, and usually needs to be interpreted with the help of an angel;
it is usually intended to provide hope and encouragement for people in the midst of severe trials and tribulations.
Caution 1: “The Apocalypse” is an alternate name (used especially by Protestants) for the “Book of Revelation” in the NT.
Caution 2: “The Little Apocalypse” or “The Apocalyptic Discourse” are names sometimes given to Mark 13 (and parallel passages in Matt 24 and Luke 21), containing the teachings of Jesus about the future of Jerusalem and the end of the world.
Scholarly Definition of “Apocalypse”(from the SBL’s “Apocalypse Group”; published in J. J. Collins, Semeia 14 [1979] 9):
" ‘Apocalypse’ is a genre of revelatory literature with a narrative framework,
in which a revelation is mediated by an otherworldly being to a human recipient,
disclosing a transcendent reality which is
both temporal, insofar as it envisages eschatological salvation,
and spatial insofar as it involves another, supernatural world."
Addition to the Definition, incorporating the purpose of the genre, from the suggestions of Hellholm (1982) & Aune (1986):
“.intended to interpret the present, earthly circumstances in light of the supernatural world and of the future,
and to influence both the understanding and the behavior of the audience by means of divine authority.”
Subdivisions or Types of Apocalypses:
Apocalypses can be classified according to features in their CONTENT:
Some apocalypses contain “Otherworldly Journeys” (e.g., the seer is purportedly taken on a tour of heaven)
Others do not contain “Otherworldly Journeys” (e.g., while seeing heavenly things, the seer stays on earth)
Apocalypses can also be classified according to their primary REFERENTS:
Some apocalypses deal with Personal Eschatology (the death and after-life of individuals)
Others focus more on Ethnic or National Eschatology (the end of a nation or empire)
Many others contain Cosmic Eschatology (the ultimate end of the whole world)
