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.
Minna von Barnhelm Minna von Barnhelm or the Soldiers' Happiness (German: "Minna von Barnhelm oder das Soldatenglück" ) is a "lustspiel" or comedy by the German author Gotthold Ephraim Lessing. It has five acts, was begun in 1763 and completed in 1767 – its author put the year 1763 on the official title page, presumably to emphasize that the recent Seven Years' War plays a major part in the play, which is set on 22 August 1763. It is one of the most important comedies in German literature .
