The Divine Comedy Vol. III: Paradise by Dante Aligheri, translated with an introduction, notes, and commentary by Mark Musa
Having ascended to the top of Mount Purgatory, Dante the Pilgrim is ready to leave Virgil behind and be led by the love of his life, Beatrice, through Heaven. Heaven is divided into concentric spheres, one each for the moon, the five known planets (Mercury, Venus, Mars, Jupiter, Saturn), the Sun (in between Venus and Mars in this schema), the fixed stars, the Primum Mobile, and the Empyrean. As Dante and Beatrice move upwards, they meet holier and ever holier people. The journey ends with Dante beholding the Beatific Vision, i.e. God Himself as He is.
Which is not to say that all the human souls and angels in the lower spheres do not have the Beatific Vision. They are less close in a spatial way but they still have supreme happiness and a full share in the infinite wonder. The souls repeatedly tell Dante that they are content with the level they are at, for they know that it is their proper place and they have complete fulfillment.
The text, like in previous volumes, is clear and straightforward. The notes are thorough and very helpful to understand the points Dante is making. The book makes for fascinating and rewarding reading.
