Aleksandr Blok is a major Russian poet of the Silver Age who lived through the revolutions of 1905 and 1917 and responded to his times both as a poet and essayist. He is generally associated with the second generation of Symbolists, but after 1917 he also worked with the Bolshevik regime until his death in 1921. Blok’s character tended towards extreme moods that ranged from a religious yearning for the divine to an embracing of demonic and destructive forces, and these poles characterise the sharp contrasts found in his work. Although he is known primarily as a lyric poet, he also wrote essays, reviews, and lyric dramas; the latter were performed in the experimental theatres of the Silver Age and early Revolutionary period.
