Ezra Weston Loomis Pound (30 October 1885 – 1 November 1972) was an expatriate American poet and critic, and a major figure in the early modernist poetry movement. His contribution to poetry began with his development of Imagism, a movement derived from classical Chinese and Japanese poetry, stressing clarity, precision and economy of language. His works include Ripostes (1912), Hugh Selwyn Mauberley (1920) and the unfinished 120-section epic, The Cantos (1917–1969). Pound worked in London during the early 20th century as foreign editor of several American literary magazines, and helped discover and shape the work of contemporaries such as T. S. Eliot, James Joyce, Robert Frost and Ernest Hemingway.[a] Angered by the carnage of World War I, Pound lost faith in Great Britain and blamed the war on usury and international capitalism. He moved to Italy in 1924 and throughout the 1930s and 1940s embraced Benito Mussolini's fascism, expressed support for Adolf Hitler, and wrote for publications owned by the British fascist Sir Oswald Mosley. During World War II, he was paid by the Italian government to make hundreds of radio broadcasts criticizing the United States, Franklin D. Roosevelt and Jews, as a result of which he was arrested in 1945 by American forces in Italy on charges of treason. He spent months in detention in a U.S. military camp in Pisa, including three weeks in a 6-by-6-foot (1.8 by 1.8 m) outdoor steel cage, which he said triggered a mental breakdown: "when the raft broke and the waters went over me". The following year he was deemed unfit to stand trial, and incarcerated in St. Elizabeths psychiatric hospital in Washington, D.C., for over 12 years. Pound began work on sections of The Cantos while in custody in Italy. These parts were published as The Pisan Cantos (1948), for which he was awarded the Bollingen Prize in 1949 by the Library of Congress, leading to enormous controversy. Largely due to a campaign by his fellow writers, he was released from St. Elizabeths in 1958 and returned to live in Italy until his death. His political views ensure that his work remains as controversial now as it was during his lifetime; in 1933 Time magazine called him "a cat that walks by himself, tenaciously unhousebroken and very unsafe for children". Hemingway wrote: "The best of Pound's writing—and it is in the Cantos—will last as long as there is any literature."

At last, a definitive, paperback edition of Ezra Pound's finest work.

Ezra Pound's The Pisan Cantos was written in 1945, while the poet was being held in an American military detention center near Pisa, Italy, as a result of his pro-Fascist wartime broadcasts to America on Radio Rome. Imprisoned for some weeks in a wire cage open to the elements, Pound suffered a nervous collapse from the physical and emotional strain. Out of the agony of his own inferno came the eleven cantos that became the sixth book of his modernist epic, The Cantos, themselves conceived as a Divine Comedy for our time. The Pisan Cantos were published in 1948 by New Directions and in the following year were awarded the Bollingen Prize for poetry by the Library of Congress. The honor came amid violent controversy, for the dark cloud of treason still hung over Pound, incarcerated in St. Elizabeths Hospital for the Criminally Insane. Yet there is no doubt that The Pisan Cantos displays some of his finest and most affecting writing, marking an elegaic turn to the personal while synthesizing the philosophical and economic political themes of his previous cantos. They are now being published for the first time as a separate paperback, in a fully annotated edition prepared by Richard Sieburth, who also contributes a thoroughgoing introduction, making Pound's master-work fully accessible to students and general readers.
