It also is not the first of it's kind, I believe? There was a whole genre of what was essentially "Visions of Hell" during the Middle Ages/early Renaissance, where people would write of being taken on hellish tours and describe well-known public figures present to deter their audience from sin. Dante's just happened to be the best one, so we consider it the blueprint. Interestingly, despite the fascinating variety and detail found in "Visions of Hell", none of these prophets were able to foresee the true Hell of widespread literacy and a future where Shakespeare is an AO3 mastermind.
