The project, developed for the Book Fair of Turin, gave the possibility to its visitors to interact with 3D virtual Dante. The 'Sommo Poeta' answered in tercets any question raised by the participants. The system had been loaded with the content of the Divine Comedy as well as (with the help of some medievalists) with the customs of Florence from Dante’s time. Once the A.I. engine decoded the question, it was able to find the most appropriate answer to show to its interlocutor.
