When first published in 1926 this book aroused much controversy. The theory expounded in the book was that Islamic sources in general, and the writings of Ibn al-`Arabi in particular, formed the basis of Dante’s poem Divine Comedy, the poem which symbolised the whole culture of medieval Christianity. The book shows how fundamental Muslim legends of the nocturnal journey and of the ascension of the Prophet Muhammed appear in Dante’s writings.

Dante put Muhammad in one of the lowest circles of Hell. At the same time, the medieval Christian poet placed several Islamic philosophers much more honorably in Limbo. Furthermore, it has long been suggested that for much of the basic framework of the Divine Comedy Dante was indebted to apocryphal traditions about a “night journey” taken by Muhammad. Dante scholars have increasingly returned to the question of Islam to explore the often surprising encounters among religious traditions that the Middle Ages afforded. This collection of essays works through what was known of the Qur’an and of Islamic philosophy and science in Dante’s day and explores the bases for Dante’s images of Muhammad and Ali. It further compels us to look at key instances of engagement among Muslims, Jews, and Christians.

Describing Dante's descent into Hell midway through his life with Virgil as a guide, Inferno depicts a cruel underworld in which desperate figures are condemned to eternal damnation for committing one or more of seven deadly sins. As he descends through nine concentric circles of increasingly agonising torture, Dante encounters doomed souls including the pagan Aeneas, the liar Odysseus, the suicide Cleopatra, and his own political enemies, damned for their deceit. Led by leering demons, the poet must ultimately journey with Virgil to the deepest level of all. For it is only by encountering Satan, in the heart of Hell, that he can truly understand the tragedy of sin.
