Perfect example:
Revelation 17 describes a thoroughly despicable woman via a series of cryptic allusions that don't make a lot of sense on the surface.
These allusions, however come together on the obverse side of the Vespasian coin, where we see a female figure seated on the seven hills of Rome just as she's described.
This was Dea Roma, (The personification of Rome as a goddess) which the Jews absolutely despised. They saw Rome as a greater Babylon and Dea Roma as the symbol of their servitude. The called her the "mother of whores" and scrawled obscene graffiti about her in public places when they could get away with it.
Everyone at the time would have been familiar with this symbology. And that's why Revelation was copied and circulated because it made sense to the people at the time
