This pamphlet, published in Naples in 1920, contains three large pull-out charts outlining the entire Divina Commedia. The chart representing the Inferno, for example, has columns for all the circles of the Inferno, the main "spirits," the order of the dammned, the types of punishments, the monologues and moral discourses, and even the hours at which each significant event on Dante's journey occurred. Note the brief dedication appearing on the cover from the author, Antonino Giordano, to Guido Mazzoni.
