Symphony No. 1, Op. 26 and Prometheus: The Poem of Fire, Op. 60 are orchestral works by Russian composer Alexander Scriabin, composed in 1899 and 1908 respectively. The earlier symphony employs a late-Romantic orchestral language with rich harmonies and expansive forms, while Prometheus advances Scriabin's move towards mystic chromaticism and innovative harmonic colours, representing a transition in his career from conventional Romanticism to a more mystical, colour-oriented musical idiom that contributed to early 20th-century orchestral experimentation.
