How did Ezra Pound use free verse and exact images in Lustra?

In his collection Lustra, Ezra Pound utilized free verse and exact imagery to move away from the sentimental, ornate language of his earlier work toward a style characterized by economy, brevity, and clarity.1

By this stage in his career, Pound had adopted a "drier" intellectual approach, treating poetry with the precision of metal. He employed free verse to compose in the sequence of the musical phrase rather than following the rigid, metronomic patterns of traditional meter. This allowed him to capture concentrated moments of experience with an observing intelligence that felt natural and unforced.12

Pound’s use of exact visual images was central to his Imagist principles, which emphasized the direct treatment of the "thing" and the avoidance of any superfluous words. In Lustra, he applied these techniques to address a wide range of human activities and emotions efficiently, often concluding poems with perfectly paced, evocative lines. By stripping away unnecessary adjectives and focusing on concrete details, Pound ensured that each image served as a total poetic statement, reflecting his belief that it is better to present one clear image than to produce voluminous, less focused work.213
