Amadeus is the title of a stage play written in 1979 by Peter Shaffer, loosely based on the lives of the composers Wolfgang Amadeus Mozart and Antonio Salieri. Amadeus was inspired by Mozart and Salieri, a short play by Aleksandr Pushkin (later adapted into an opera of the same name by Nikolay Rimsky-Korsakov), and was itself later adapted into the film Amadeus.
