“Bill Salus on Mystery Babylon” Christ in Prophecy

So I laid down for a nap and the image of the lady riding a bull entered my mind along with “Europe””Europa”. I know the Greek myth of Europa and Zeus. I also know the image of Europa riding the bull is important in modern Europe. I’m also aware of the whore riding the beast in Revelation. What I’m waiting to understand, is why I was shown this and what I’m supposed to make of it.
