My last attempt

DR didn’t answer my question earlier. But, that’s ok.

I just want to state that there is no consensus whatsoever among serious students of the Bible about what the book of Revelation is even about, let alone what each symbol refers to. Anyone who claims to be an “expert” in bible prophecy almost certainly isn’t. But I get the feeling most people here have already figured that out.

That's not exactly true. The early Christian (and Catholic) point of view is that Revelation mirrors the sacrifice and celebration of the Eucharist in the mass. Scott Hahn does a great job explaining this in easy to digest language if you're interested.
