Prior to Asín's "La Escatologia" it was assumed that Dante drew from the long poem the "Aeneid" by the ancient Roman poet Virgil for the inspiration to create the memorable scenes of the afterlife. In his "Divina Comedia", Dante himself plays the leading role; he is guided by the deceased poet Virgil as they travel through the "Inferno" and the "Purgatorio". Asín remarks that the addition of the Muslim sources in no way detracts from Dante's achievement, and that Dante remains a luminous figure and his poem retains its exalted place in world literature.
