Final answer:
MacLeish's 'Imagery' fuses closed form with Modernist imagery, reflecting its time's artistic tensions, while Lowell's 'Summer Rain' employs free verse indicative of the Modernist movement's psychological depth and introspection.
Step-by-step explanation:
Archibald MacLeish's poem 'Imagery' and Amy Lowell's poem 'Summer Rain' offer rich examples of how poems can combine elements of closed form poetry with free verse, reflecting the transition of poetic styles over different time periods. MacLeish's 'Imagery' is a sonnet, which adheres to a strict, closed poetic form with a fixed rhyme scheme and meter, a reflection of the early 20th-century Modernist tendencies to bridge traditional structures with evocative imagery. However, MacLeish infuses this traditional form with modernist aesthetics, using images to evoke rather than tell, much like the Imagist poets of his time aimed to achieve.
In contrast, Lowell's 'Summer Rain' utilizes free verse, marked by a lack of consistent rhyme and meter but still resonating with rhythm through the use of repetition and onomatopoeia, characteristic of the Imagist movement. This free verse structure reflects the early 20th-century shift towards Modernism and an emphasis on the freedom to express, where traditional constraints are loosened to capture the cadence of natural speech and psychological complexity. Her work reflects a time when literary expression was becoming more introspective and form was evolving to accommodate the personal voice.
