Legend of the Invisible City of Kitezh

The Legend of the Invisible City of Kitezh and the Maiden Fevroniya (Russian: Сказание о невидимом граде Китеже и деве Февронии, romanized: Skazániye o nevídimom gráde Kítezhe i déve Fevrónii ) is an opera in four acts by Nikolai Rimsky-Korsakov. The libretto was written by Vladimir Belsky, and is based on a combination of two Russian legends: those of Saint Fevroniya of Murom and of the city of Kitezh, which became invisible when attacked by the Tatars. The opera was completed in 1905, and the premiere performance took place at the Mariinsky Theatre in St. Petersburg, on February 7, 1907, the last in Rimsky-Korsakov's lifetime.
