Don Juan (Spanish) or Don Giovanni (Italian) is a legendary, fictional libertine whose story has been told many times by many authors. El burlador de Sevilla y convidado de piedra (The Trickster of Seville and the Stone Guest) by Tirso de Molina is a play set in the fourteenth century that was published in Spain around 1630. Evidence suggests it is the first written version of the Don Juan legend. Among the best known works about this character today are Molière's play Dom Juan ou le Festin de pierre (1665), Byron's epic poem Don Juan (1821), José de Espronceda's poem El estudiante de Salamanca (1840) and José Zorrilla's play Don Juan Tenorio (1844). Along with Zorrilla's work (still performed every year on November 2nd throughout the Spanish-speaking world), arguably the best known version is Don Giovanni, an opera composed by Wolfgang Amadeus Mozart with libretto by Lorenzo da Ponte, first performed in Prague in 1787 (with Giacomo Casanova probably in the audience) and itself the source of inspiration for works by E. T. A. Hoffmann, Alexander Pushkin, Søren Kierkegaard, George Bernard Shaw and Albert Camus. Don Juan is used synonymously for "womanizer", especially in Spanish slang, and is often used in reference to hypersexuality.
