Glossary of Literary Theory by Greig E. Henderson and Christopher Brown

Imagism:

A school of poetry prominent in Great Britain and North America between 1909 and 1918. According to T. E. Hulme, poetry should eliminate excess verbiage and concentrate on the absolutely accurate presentation of a concrete and precise image. The objectives of Imagism were accurate description, objective presentation, concentration and economy, new rhythms, freedom of choice in subject matter, suggestion rather than explanation, and the absence of clichés. In Ezra Pound's phrase, the natural object is always the adequate symbol.
