'Amphitryon' is a French-language three-act by Molière which is based on the story of the Greek mythological character Amphitryon as told by Plautus. The plot can be summarized as follows. After his wedding night with beautiful Alcmene, Amphitryon leaves to participate in a war. Jupiter, who is fascinated by Alcmene's beauty, comes to earth under the appearance of Amphitryon, accompanied by Mercury who has taken the appearance of Amphitryon's servant Sosie. Amphitryon is successful in war and sends Sosie back home to report this. Sosie is greeted by his look-alike Mercury, who beats him and convinces him that Mercury is the real Sosie. The real Amphitryon meets Alcmene and is naturally confused and shocked by her account of an amorous night.
