What is the full name of the author of Dante's Inferno?
As you might have already guessed, "Inferno" is just a part of the work of this classical author. So the part mentioned above (Inferno) happens to be the first of three existing ones as the poem describes three other sides: Inferno, Purgatorio, Paradiso.
It's also an interesting fact that the original title of the work was just "Comedy" - the "Divine" attachment appeared more than 200 years after the poem had been written.
