Both authors present a similar style by the time in which they lived. The 20th century poetry consisted of imaginary writing style becoming popular, as well as how it was related to the world war. Furthermore, the process of making the poetry sound biblical and remark the women’s rights became a popular tendency on literature at that time.
On the one hand T. S. Eliot considered a very important modernism poet, used to work with themes that rejected the traditional 19th norms and was orientated modernism through the use of fragmentation, free verse, contradictory illusions, metaphors as a poetic device, and multiple views on feeling by giving unanimated objects voice and perspectives as it can be appreciated in his poem “Rhapsody on a Windy Night”. Also, he worked with Victorian and romantic writing tones that can be noticed in “The Love Song of J. Alfred Prufrock” and “The Waste Land.”
On the other hand, Carl Sandburg, also implies different metaphors as poetic devices in his poems, in conjunction with Eliot, with the use of free verse, imagination, and comparisons by giving voice to objects and nature components, such as rivers and mountains. For instance, Carl's idyllic style emerged from numerous different artists on account of its absence of frame and structure. The greater part of his lyrics appear as though he's coolly portraying a theme. As appeared in the lyric "Passing Snips Proud Men", Sandburg utilizes a considerable measure of easygoing word use and slang.
This free verse and lack of a structure, along with the imaginary use of metaphors and reality are the points were both authors meet each other’s writing style.
