Did Dante Alighieri, author of "The Divine Comedy" as a young man in Florence sleep with Beatrice Portinari before and after her marriage? Did the poet travel after her death through Hell to find her again? The clues to this academic detective story, writes Mark Jay Mirsky, lie not only in Dante's earlier poetry, "The New Life", or in "The Divine Comedy", but in the "Zohar of Moses de Leon", a Jewish text written some years before and based on Neoplatonic ideas similar to those that inspired Dante. "Purgatorio" and "Paradiso", the second and third volumes of the "Commedia", are inaccessible to most reader unfamiliar with the boldness of Dante's use of the philosophical debate in the Middle Ages. Does Dante's "Commedia" hint at his hope of intimacy with Beatrice in the Highest Heaven? Mirsky distinctively traces the influence on Dante of Provencal poets, mediaeval theologians, Dante's personal life, and the sources of his classical education to propose a radical reading of Dante. The text compounds the riddles of dream, poetry, philosophy and Dante's concealed autobiography in his work. It treats the "Commedia" in the spirit of its title, as a hopeful and comic version of the other world.
