Purgatorio, region in Dante's “Commedia” intermediate between the Inferno, region of lost souls, and the Paradiso, region of saved souls, and full of all manner of obstructions which the penitent, who would pass from the one to the other, must struggle with in soul-wrestle till he overcome, the most Christian section, thinks Carlyle, of Dante's poem.
