The Diary of a Madman is a one-act chamber opera by the composer Humphrey Searle. It is based on the short story of the same name by Nikolai Gogol. The opera was premiered in 1958 in Berlin. The libretto is by the composer.
The work, which is the first of Searle's operas, was commissioned by Hermann Scherchen, then the director of the Berlin Festival. Scherchen gave Searle complete choice of subject, stipulating only that the orchestra be of no more than 15 players, and that there should be no more than four singing roles. Searle had recently written incidental music for a radio production of Gogol's story, starring Paul Scofield, and decided to choose the story for his opera, providing completely new music.
The libretto was written by the composer, based on the translation of Gogol's story by D. S. Mirsky. The opera is scored for an orchestra of single strings, woodwind and brass, with two percussionists. An electronic tape is also specified to produce particular sound effects. The voices of two dogs are directed to be sung by the same performer, using a loudspeaker. The opera was written in London and Amalfi between April and June 1958, and was premiered at the Berlin Festival on 3 October 1958, with Scherchen conducting.
The action takes place in St. Petersburg in 1833. The opera is in five continuous scenes, each corresponding to a date in the diary, which is projected onto the backcloth, and following the outline of Gogol's story. In Scene 1 ("October 3") we meet the feckless government clerk Popristchin, short of money and in love with Sophie, the daughter of his boss. His sanity is clearly in question as he overhears a conversation between Sophie's poodle and a dachshund belonging to a passing girl (highlighted, as in most of Popritschin's future delusions, by the accompaniment of prepared electronic effects on tape).Scene 2 ("October 4"), finds Popritschin reprimanded by his boss for his inefficiency, and for his hopeless dreams of Sophie. In Scene 3 ("October 5") the increasingly demented Popritschin seeks to retrieve the correspondence which he imagines to exist between the two dogs. He believes that he has found it and that it describes Sophie's forthcoming marriage to a Gentleman of the Chamber, and also contains some rude comments about Popritschin himself.Scene 4 is dated "43 April 2000 A. D." Popritschin is now suffering from delusions of grandeur and believes himself to be King Ferdinand VIII of Spain. Turning up to his office he creates chaos before the astonished Sophie.Scene 5, dated "Madrid, Martober 86", finds Popritschin incarcerated and taunted in a lunatic asylum.
