The play is a study of religious fanaticism and self-serving manipulation based on an episode in the traditional biography of Muhammad in which he orders the murder of his critics. Voltaire described the play as "written in opposition to the founder of a false and barbarous sect".

This book explores how the figure of the Prophet Muhammad was misrepresented in English and wider Christian culture between 1480 and 1735. By tracing the ways in which 'Mahomet' was written and rewritten, contested and celebrated, this study explores notions of identity and religion, and the resonances of this history today.

Heretic and impostor or reformer and statesman? The contradictory Western visions of Muhammad In European culture, Muhammad has been vilified as a heretic, an impostor, and a pagan idol. But these aren’t the only images of the Prophet of Islam that emerge from Western history. Commentators have also portrayed Muhammad as a visionary reformer and an inspirational leader, statesman, and lawgiver. In Faces of Muhammad, John Tolan provides a comprehensive history of these changing, complex, and contradictory visions. Starting from the earliest calls to the faithful to join the Crusades against the “Saracens,” he traces the evolution of Western conceptions of Muhammad through the Reformation, the Enlightenment, and the nineteenth and twentieth centuries, and up to the present day. Faces of Muhammad reveals a lengthy tradition of positive portrayals of Muhammad that many will find surprising. To Reformation polemicists, the spread of Islam attested to the corruption of the established Church, and prompted them to depict Muhammad as a champion of reform. In revolutionary England, writers on both sides of the conflict drew parallels between Muhammad and Oliver Cromwell, asking whether the prophet was a rebel against legitimate authority or the bringer of a new and just order. Voltaire first saw Muhammad as an archetypal religious fanatic but later claimed him as an enemy of superstition. To Napoleon, he was simply a role model: a brilliant general, orator, and leader. The book shows that Muhammad wears so many faces in the West because he has always acted as a mirror for its writers, their portrayals revealing more about their own concerns than the historical realities of the founder of Islam.
