Konstantin Alekseyevich Korovin (1861 – 1939) was a leading Russian Impressionist painter. Konstantin's relative Illarion Pryanishnikov was also a prominent painter of the time and a teacher at the Moscow School of Painting, Sculpture and Architecture. In the beginning of the 20th century, Korovin focused his attention on the theater. He moved from Mamontov's opera to the Mariinsky Theatre in St. Petersburg. Departing from traditional stage decor, which only indicated the place of action, Korovin produced a mood decor conveying the general emotions of the performance.
