Paradise by Dante Alighieri

Paradiso (Italian for "Paradise" or "Heaven") is the third and final part of Dante's Divine Comedy, following the Inferno and the Purgatorio. It is an allegory telling of Dante's journey through Heaven, guided by Beatrice, who symbolises theology. In the poem, Paradise is depicted as a series of concentric spheres surrounding the earth, consisting of the Moon, Mercury, Venus, the Sun, Mars, Jupiter, Saturn, the Fixed Stars, the Primum Mobile and finally, the Empyrean. It was written in the early 14th century. Allegorically, the poem represents the soul's ascent to God.
