“ At his side his faithful knave, droll Leporello, expostulating with his master very piously sometimes, yet bound to him by potent magnetism, both of metal and of character (for passion like Giovanni’s will be served.) Leporello is the foil and shadow to his master, and adds to the zest of his life-long intoxication by the blending of the comic with this exquisite wild fever of the blood. Throughout the whole he plays the part of contrast and brings all back to reality and earth again, lest the history should take too serious possession of us. ”
