Does Werther or War and Peace have more acts?
War and Peace (opera) War and Peace (Op. 91) (Russian: Война и мир , "Voyna i mir") is an opera in two parts (an Epigraph and 13 scenes), sometimes arranged as five acts, by Sergei Prokofiev to a Russian libretto by the composer and Mira Mendelson, based on the novel "War and Peace" by Leo Tolstoy. Although Tolstoy's work is classified as a novel, the 1812 invasion of Russia by the French was based on real-life events, and some real-life people appear as characters in both the novel and the opera, e.g. Prince Mikhail Kutuzov and Napoleon Bonaparte.
Wär Gott nicht mit uns diese Zeit, BWV 14 Johann Sebastian Bach composed the church cantata Wär Gott nicht mit uns diese Zeit (Were God not with us at this time), BWV 14 , in Leipzig in 1735 for the fourth Sunday after Epiphany and first performed it on 30 January 1735, a few weeks after his "Christmas Oratorio". The cantata, in Bach's chorale cantata format, is based on Martin Luther's hymn "Wär Gott nicht mit uns diese Zeit". Its text paraphrases Psalm 124, focussing on the thought that our life depends on God's help and is lost without it.
