Dante’s reference is the Divine Comedy Dante Alighieri, probably baptized Durante di Alighiero degli Alighieri and often referred to simply as Dante (1265 – 14 September 1321), was an Italian poet, writer and philosopher. His Divine Comedy, originally called Comedìa (modern Italian: Commedia) and later christened Divina by Giovanni Boccaccio, is widely considered one of the most important poems of the Middle Ages and the greatest literary work in the Italian language. Dante was instrumental in establishing the literature of Italy. His depictions of Hell, Purgatory and Heaven provided inspiration for the larger body of Western art and literature. The Divine Comedy is an Italian narrative poem by Dante Alighieri, begun c. 1308 and completed in 1320, a year before his death in 1321. It is widely considered the pre-eminent work in Italian literature and one of the greatest works of world literature. The poem's imaginative vision of the afterlife is representative of the medieval worldview as it had developed in the Western Church by the 14th century. It is divided into three parts: Inferno, Purgatorio, and Paradiso. The narrative takes as its literal subject the state of the soul after death and presents an image of divine justice meted out as due punishment or reward, and describes Dante's travels through Hell, Purgatory, and Paradise or Heaven. Allegorically the poem represents the soul's journey towards God, beginning with the recognition and rejection of sin (Inferno), followed by the penitent Christian life (Purgatorio), which is then followed by the soul's ascent to God (Paradiso). In the poem, the pilgrim Dante is accompanied by three guides: Virgil (who represents human reason, and who guides him for all of Inferno and most of Purgatorio); Beatrice (who represents divine revelation, theology, faith, and grace, guiding him at the end of Purgatorio and for most of Paradiso) and Saint Bernard of Clairvaux (who represents contemplative mysticism and devotion to Mary the Mother, guiding him in the final cantos of Paradiso).
