What are the motifs in Hugh Selwyn Mauberley by Ezra Pound?

WW1 is a recurring idea. World War I was a cataclysmic event in Pound's early career, although he barely mentioned it while the war was taking place in either his correspondence or his literary work. Imagism's harsh attacks on late Victorian poetry and the frankly violent language of the Vorticist movement headed by Pound seemed ridiculous when the real slaughter began. Eventually and inevitably, Pound lost friends in the conflict. He even wrote a book about one of these friends, a French sculptor named Henri Gaudier-Brzeska, who had carved a "Hieratic Head of Ezra Pound" out of a discarded chunk of marble Pound found for him under a London bridge.
