Final answer:
Dante describes ten levels of Heaven in Paradiso.
Step-by-step explanation:
In Dante's Paradiso, Dante describes there being ten levels of Heaven. Each level, or sphere, corresponds to a different celestial body and is inhabited by different types of souls. The spheres are arranged in a hierarchical order, with the most perfect and divine sphere, the Empyrean, at the top. Dante's journey through these spheres represents his ascent towards the ultimate union with God.
