Does Werther or War and Peace have more acts?
Werther Werther is an opera ("drame lyrique") in four acts by Jules Massenet to a French libretto by Édouard Blau, Paul Milliet and Georges Hartmann (who used the pseudonym Henri Grémont). It is loosely based on the German epistolary novel "The Sorrows of Young Werther" by Johann Wolfgang von Goethe, which was based both on fact and on Goethe's own early life. Earlier examples of operas using the story were made by Kreutzer (1792) and Pucitta (1802).
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.
