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.
