By 1784, Wolfgang Amadeus Mozart was internationally renowned as the composer of The Marriage of Figaro, and consequently received a commission from the Prague Opera House to compose another opera. The resulting product was Don Giovanni, which tells the tale of a criminal and seducer who nevertheless evokes sympathy from audiences, and whose behavior fluctuates from moral crisis to hilarious escapade. While Don Giovanni is widely considered to be Mozart's greatest achievement, eighteenth century audiences in Vienna – Mozart's own city – were ambivalent at best. The opera mixed traditions of moralism with those of comedy – a practice heretofore unknown among the composer's works – creating a production that was not well liked by conservative Viennese audiences. Meanwhile, however, Don Giovanni was performed to much acclaim throughout Europe.
