The Divine Comedy is a long Italian narrative poem by Dante Alighieri, begun c. 1308 and completed in 1320, a year before his death in 1321. It is widely considered to be 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 world-view as it had developed in the Western Church by the 14th century. It helped establish the Tuscan language, in which it is written (also in most present-day Italian-market editions), as the standardized Italian language. It is divided into three parts: Inferno, Purgatorio, and Paradiso.
