Deborah Parker at the Institute for Advanced Technology in the Humanities has apparently spearheaded turning Dante Aligheri's Divine Comedy into a multimedia project called "The World of Dante."
Anybody who's a fan of The Divine Comedy needs to check this website out. Any DM who wants to run a game set in Hell or in Italy should also take a look.
First, you have the art gallery, featuring the works by Gustave Dore and others.
Second, you have the maps of Hell, Purgatory, Heaven, and Italy around the year 1300.
Third, here's the music--yes music--that Dante refers do in the Purgatorio and Paradiso.
Fourth, there's also a timeline of the events in Dante Aligheri's life.
There's also a number of other resources like search engine, stuff for teachers, and so on.
But here's what really fantastic about this website:
Each Canto features both the original Italian and English translations side-by side. There's also a menu on the right that cross references all of the people, monsters, deities, music, and other stuff related to that particular Canto.
I can think of all kinds of uses for this at the gaming table (and, of course, scholarly research).
