Question: Which was written first, Boris Godunov or La vida breve?
Context: "Viva la Vida" ( ; ] ) is a song by the British rock band Coldplay.  It was written by all members of the band for their fourth album, "Viva la Vida or Death and All His Friends" (2008), and was released as the second single from the album.  On the album, this song segues directly into the next track, "Violet Hill".  "Viva la Vida" is Spanish for "Long Live Life" or "Live (the) Life".  It is recognized as one of Coldplay's signature songs. Boris Godunov (Russian: Борис Годунов , "Borís Godunóv") is an opera by Modest Mussorgsky (1839–1881).  The work was composed between 1868 and 1873 in Saint Petersburg, Russia.  It is Mussorgsky's only completed opera and is considered his masterpiece.  Its subjects are the Russian ruler Boris Godunov, who reigned as Tsar (1598 to 1605) during the Time of Troubles, and his nemesis, the False Dmitriy (reigned 1605 to 1606).  The Russian-language libretto was written by the composer, and is based on the drama "Boris Godunov" by Aleksandr Pushkin, and, in the Revised Version of 1872, on Nikolay Karamzin's "History of the Russian State". La vida breve (Spanish "Life is Short" or "The Brief Life") is an opera in two acts and four scenes by Manuel de Falla to an original Spanish libretto by Carlos Fernández-Shaw.  Local (Andalusian) dialect is used.  It was written between August 1904 and March 1905, but not produced until 1913.  The first performance was given (in a French translation by Paul Millet) at the Casino Municipal in Nice on 1 April 1913.  Paris and Madrid performances followed, later in 1913 and in 1914 respectively.  Claude Debussy played a major role in influencing Falla to transform it from the number opera it was at its Nice premiere to an opera with a more continuous musical texture and more mature orchestration.  This revision was first heard at the Paris premiere at the Opéra-Comique in December 1913, and is the standard version. Nuria Pomares is a dancer.
