Amphitryon is an English language comedy by John Dryden which is based on Molière's 1668 play of the same name which was in turn based on the story of the Greek mythological character Amphitryon as told by Plautus in his play from ca. 190-185 B.C. Dryden's play, which focuses on themes of sexual morality and power, premiered in London in 1690. Notable innovations in Dryden's adaptation compared to previous plays on Amphitryon included music by Henry Purcell and the character of Phaedra, who flirts with Sosia but is eventually won over by Mercury's promises of wealth.
