A sensual libertine, like the Duke in
Don Giovanni's pleasure in seducing women is not sensual but arithmetical; his satisfaction lies in adding one more name to his list which is kept for him by Leporello. Everything possible, therefore, should be done to make him as inconspicuous and anonymous in appearance as an FBI agent. If he is made handsome, then his attraction for women is a bias in his choice, and if he is made ugly, then the repulsion he arouses in women is a challenge.

Has it not, in fact, been Leporello all along who was really the master and Don Giovanni really his servant? It is Leporello who keeps the list and if he lost it or forgot to keep it up-to-date or walked off with it, Don Giovanni would have no
