Here's why:
* Emphasis on sensory experience: HD uses highly evocative imagery to create a vivid picture of the pool and its surroundings. The poem is rich with visual details ("the water, green, and the pool, blue," "The water, green, was filled with the sky"), tactile sensations ("the rough, white stones," "the sand, smooth and cool"), and auditory elements ("the sound of the water falling, falling").
* Objectivity and precision: Her imagery is presented in a detached, almost objective manner, avoiding personal emotions or interpretations. This approach is characteristic of Modernist poetry, which sought to capture reality directly and avoid sentimentality.
* Symbolism: While HD doesn't explicitly explain the meaning of the images, she uses them symbolically to evoke ideas of time, change, and the passage of life. The pool itself can be seen as a symbol of the cycle of nature, while the falling water represents the relentless flow of time.
* Minimalist language: HD uses a concise, direct language, avoiding unnecessary ornamentation or elaborate metaphors. This focus on simplicity and clarity is another hallmark of Modernist poetry.
While other techniques like free verse and fragmentation are also present in the poem, imagery is the most prevalent and defining characteristic of HD's style in "The Pool."
