Opera and Drama (German: Oper und Drama) is a book-length essay written by Richard Wagner in 1851 setting out his ideas on the ideal characteristics of opera as an art form. It belongs with other essays of the period in which Wagner attempted to explain and reconcile his political and artistic ideas, at a time when he was working on the libretti, and later the music, of his Ring cycle.
As the longest of all of Wagner's literary works apart from his autobiography Mein Leben (376 pages long in its English translation), Opera and Drama is perhaps better described by the word 'treatise', as suggested by its translator W. Ashton Ellis. It follows from his earlier writings of the period 1849–50: more particularly "Art and Revolution" (1849), which sets out Wagner's ideals for an artwork that would be appropriate for his ideal society; "The Artwork of the Future" (1849), which sets out ideas for a music drama which would meet such ideals; and "Jewishness in Music" (1850), which (amongst other matters) excoriates commercialism in art.
Wagner wrote the entire book in Zurich in four months between October 1850 and January 1851. He gave public readings of large extracts in Zurich in early 1851, with a dedication to Theodor Uhlig. Parts of it were published in the Monatschrift, an intellectual magazine, and the whole was published in Leipzig later in 1851. A second edition appeared in 1868, with a dedication to the German political writer Constantin Frantz.
The earliest English translation had appeared as early as 1856, but the translation generally used in the English-speaking world is that by W. Ashton Ellis, first published in 1893. Like the original, this is full of complex phrases, grammar and structure, which render the work difficult to absorb. Even Ellis commented that some 'tantalising epithets seemed to group themselves into a coruscation baffling all description.'
