Méphistophélès, less an intellectual "principle of negation" than a devilishly attractive magician, draws his attention to Marguerite - and Faust is delighted. A deal is quickly struck: the devil serves Faust on earth, and after Faust's death it is to be the other way around. Marguerite is also not unimpressed by what Méphistophélès has to offer: material luxury and sensual pleasure, often musically illustrated by Gounod with a waltz. But the relationship between Faust and Marguerite remains an episode, as Faust is drawn to new attractions, while Marguerite remains pregnant, only to see her unfaithful lover kill her brother.
