To show that it is impossible to think of "Mefistofele" except as a series of disconnected episodes, it suffices to point out that its prologue, epilogue, and four acts embrace a fantastic parody or perversion of Goethe's Prologue in Heaven, a fragment of his Easter scene, a smaller fragment of the scene in Faust's study, a bit of the garden scene, the scene of the witches' gathering on the Brocken, the prison scene, the classical Sabbath in which Faust is discovered in an amour with Helen of Troy, and the death and salvation of Faust as an old man. Can any one who knows that music, even of the modern dramatic type, in which strictly musical forms have given way to as persistent an onward flow as the text itself, must of necessity act as a clog on dramatic action, imagine that such a number and variety of scenes could be combined into a logical, consistent whole, compassed by four hours in performance? Certainly not. But Boito is not content to emulate Goethe in his effort to carry his listeners "from heaven through the earth to hell"; he must needs ask them to follow him in his exposition of Goethe's philosophy and symbolism. Of course, that is impossible during a stage representation, and therefore he exposes the workings of his mind in an essay and notes to his score. From these we may learn, among other things, that the poet-composer conceives Faust as the type of man athirst for knowledge, of whom Solomon was the Biblical prototype, Prometheus the mythological, Manfred and Don Quixote the predecessors in modern literature. Also that Mephistopheles is as inexhaustible as a type of evil as Faust is as a type of virtue, and therefore that this picturesque stage devil, with all his conventionality, is akin to the serpent which tempted Eve, the Thersites of Homer, and--mirabile dictu!--the Falstaff of Shakespeare!
