I always thought it was kind of fascinating to think about how much of Hell is actually early Catholic in origin. Most of the bible's descriptions of Hell come from the book of Revelation, which is basically just some guy's drug-trip 100 years after historical Jesus died. The apostles also talk about Hell a little bit, but not really with much description. And they were just people like anybody else.
Historical Jesus barely talks about Hell at all in the bible, and when he does it's somewhat ambiguous whether or not he's talking about an actual literal trash dump not too far outside of Jerusalem's city limit (translation notes on this are fascinating).
Most of the modern concept of Hell really comes from Revelation and from works of art/books written during long after the events of the Bible were supposed to take place.
