The literary movement that championed the use of precise language to create a single evocative mental picture for readers is Imagism.

Key features of Imagism:

* Emphasis on precise language and imagery: Poets sought to use words that evoked clear and vivid images in the reader's mind.

* Conciseness and directness: They valued brevity and avoided unnecessary ornamentation.

* Focus on the concrete and sensory details: Imagist poetry often dealt with everyday experiences and objects, using sensory language to create a strong impression.

* Free verse: Imagists rejected traditional poetic forms and embraced free verse to allow for greater flexibility in expression.

Notable Imagist poets include:

* Ezra Pound

* Amy Lowell

* H.D. (Hilda Doolittle)

* T.S. Eliot (in his early work)

* William Carlos Williams

The apparition of these faces in the crowd;

Petals on a wet, black bough.

This poem captures the essence of Imagism through its vivid imagery, concision, and use of free verse.
