It is difficult to say if it is Mozart's brilliant music or the absolutely brilliant libretto by Lorenzo da Ponte that is more eminent in the famous dramma giocoso. The story about an incurable lecher is incomparable with the trivial tales which most opera comique works were based on at that time. Da Ponte referred here to Tirso de Molina's play El Burlador de Sevilla, which also inspired Molière's Don Juan. However, one should remember that Don Giovanni's love affairs let the authors build a much more significant plot. The dissolute nobleman disappears in the abyss not because he deluded a thousand and three women but because, mocking Commendatore, he disturbed the order of the world of the dead. It is not a story with a moral: it is a story about an illusion of free will and about the fall of a rebellious angel.
