The Social Network of Dante’s Inferno

“The first product coming out from this crazy idea was “The Social Network of Dante’s Inferno“, presented in the 2010 edition of the “Arts, Humanities and Complex Networks” symposium of NetSci and then published in a 2011 special issue of the Leonardo journal. In this work we were moved by the question: is a network of characters following some particular predictive patterns? If so: which ones?

“So we took a digital copy of Dante’s Inferno, where all interactions and characters were annotated with extra information (who the character was, if she was a historic or mythological figure, when she lived, …). We then considered each character as a node of the network. We created an edge between two characters if they had at least a direct exchange of words. Normal people would call this “a dialogue”.

“The double-focus point of the Commedia emerges quite naturally, as Dante and Virgilio are the so-called “hubs” of the system. It is a nice textbook example of the rich-get-richer effect, a classic network result. But contrary to what the title of the paper says, we went beyond that. There are not only “social” relationships. Each character is also connected to all the information we have about her. There is another layer, a semantic one, where we have nodes such as “Guelph” or “Middle Ages”. These nodes enable us to browse the Commedia as a network of concepts that Dante wanted to connect in one way or another. One can ask some questions like “are Ghibelline characters preferably connected to historic or mythological characters?” or “what’s the centrality of political characters in the Inferno as opposed to the Purgatorio?” and create one’s own interpretation of the Commedia.” […]    Michele Coscia, Michele Coscia, 12 December, 2013
