The bulk of Pound's work on The Cantos began after his move to Italy. Like all the other great epics, it is the story of good and evil, a descent into hell and progress to paradise. Its hundreds of characters fall into three groups: those who enjoy hell and stay there; those who experience a metamorphosis and want to leave; and a few who lead the rest to paradiso terrestre. He began work on it in 1915, but there were several false starts and he abandoned most of his earlier drafts, beginning again in 1922. The subject matter ranges from Odysseus, Troy, Dionysus, Malatesta Confucius, and Napoleon, to Jefferson and Mussolini, Chinese history, Pisa, and usury, relying on memories, diaries, jokes, hymns, anecdotes, ideogrammic translation, and up to 15 different languages. Allen Tate, who supported Pound for the Bollingen Prize for the sections of The Cantos known as the Pisan Cantos, writes that the poem is not about anything, and has no beginning, middle, or end. He argues that Pound was incapable of sustained thought and was "at the mercy of random flights of 'angelic insight,' Icarian self-indulgences of prejudices."
