At the same time, the neoclassicism that became fashionable in the 1920s is represented by Stravinsky's opera buffa "Mavra" (1922) and his opera-oratorio "Oedipus Rex" (1927). Later in the century his last opera, "The Rake's Progress" (1951), also marks the end of the neoclassical phase of his compositions. Other operas of this period by composers identified as neoclassicists include Paul Hindemith's "Mathis der Maler" (1938), Sergei Prokofiev's "Voina y Mir" (War and Peace, 1941–1943), Bohuslav Martinu's "Julietta aneb snár" (1937) and Francis Poulenc's "Les mamelles de Tirésias" (1945).
