This book explores the changing perception of time and space in avant-garde modernist and contemporary poetry. The author characterizes the works of modern Russian French and Anglo-American poets based on their attitudes towards reality time space and history revealed in their poetics. The author compares the work of major Russian innovative poets Osip Mandelstam Velimir Khlebnikov Vladimir Mayakovsky and Joseph Brodsky with that of W. B. Yeats T. S. Eliot Ezra Pound and in spite of the postmodernist estrangement of reality the author proves that similar traces can be found in the work of contemporary American poets John Ashbery and Charles Bernstein. Both affinities and drastic differences are revealed in the poets' attitudes towards time-space reality and history.
