Among later Russian symphonic poems, Sergei Rachmaninoff's The Rock shows as much the influence of Tchaikovsky's work as Isle of the Dead (1909) does its independence from it. A similar debt to his teacher Rimsky-Korsakov imbues Igor Stravinsky's The Song of the Nightingale, excerpted from his opera The Nightingale. Alexander Scriabin's The Poem of Ecstasy (1905–08) and Prometheus: The Poem of Fire (1908–10), in their projection of an egocentric theosophic world unequalled in other symphonic poems, are notable for their detail and advanced harmonic idiom.
