This is an amazing resource for teachers of the Divine Comedy produced by the Institute for Advanced Technology in the Humanities at the University of Virginia. The site contains pages dedicated to images, music, timelines, popular culture references, and maps that help broaden your understanding of Dante's works. The interactive maps and fully searchable texts are essential when thinking about in-class exercises, assignments, and presentations. There is a special section dedicated to resources for teachers. If you only have time for one stop on the Internet, this is your place.
