I had at home two books related to Bologna, which I decided to bring with me as holiday reads.
The first is a French band dessinée, "Journal d'Italie, Trieste Bologne", by David B. The clue is in the title.
The second is film director Alejandro Jodorowsky's "The Way of the Tarot". Though nobody knows exactly where or when the tarot originated, some academics believe it was in Bologna.
