In a 1745 letter recommending the play to Pope Benedict XIV, Voltaire described Muhammad as "the founder of a false and barbarous sect" and "a false prophet". Voltaire wrote: "Your holiness will pardon the liberty taken by one of the lowest of the faithful, though a zealous admirer of virtue, of submitting to the head of the true religion this performance, written in opposition to the founder of a false and barbarous sect. To whom could I with more propriety inscribe a satire on the cruelty and errors of a false prophet, than to the vicar and representative of a God of truth and mercy?" His view was modified slightly for "Essai sur les Moeurs et l'Esprit des Nations", although it remained negative. In 1751, Voltaire performed his play "Mohamet" once again, with great success.
