What are some literary devices within the poem "Chicago" in Sandburg's Chicago Poems?
In Sandburg's poem "Chicago," the entire first stanza uses personification, as well as an extended metaphor as the writer compares the city to the things people do:
Hog Butcher for the World,
Tool Maker, Stacker of Wheat,
Player with Railroads and the Nation's Freight Handler;
Stormy, husky, brawling,
City of the Big Shoulders...
Personification gives human characteristics to non-human things. Chicago is a place (a thing) that cannot do human things such as "brawling" or have physical characteristics such as "Big Shoulders."
The extended metaphor makes a comparison that continues throughout several lines. It is defined as:
...a metaphor developed at great length
It lists professions that people have, but assigns those professions to the city, rather than to people. The city, for example, cannot be a hog butcher or toolmaker: only its people can, thereby supplying to the needs of the nation or even the world.
Similes are comparisons of dissimilar things that share similar qualities, using "like" or "as" in the comparison. The poem has several similes:
Fierce as a dog with tongue lapping for action, cunning as a savage pitted against the wilderness...
In these similes, Chicago is compared to dogs and savages. Here are examples of personification, as are the closing lines of the poem. However, these closing lines use brilliant imagery to provide a picture of diverse aspects of Chicago with such clarity, that Sandburg's personification brings alive the spirit of the city, one which he obviously admires.
In these lines, the words form images in the reader's brain. Sensory details or descriptive details are used—details that appeal to one or more of the senses: in this case, visual senses.
[The five senses] are our primary source of knowledge about the world. Therefore, writing which incorporates vivid, sensory detail is more likely to engage and affect the reader.
To make his writing more engaging, Sandburg uses impressive sensory details: here is the image of a "dusty mouth" contrasted with "white teeth."
Under the smoke, dust all over his mouth, laughing with white teeth...
Under the terrible burden of destiny laughing as a young man laughs,
Laughing even as an ignorant fighter laughs who has never lost a battle...
Sandburg brings to mind the essence of the city, the life it seems to have—directing the reader's attention to the part of its "body" that refer to the most caring aspects of a human being:
Bragging and laughing that under his wrist is the pulse, and under his ribs the heart of the people,
There is joy in the city; it has a pulse that infers it has a life of its own; and it has a heart—but not of its own: it houses "the heart of the people" and an element of the goodness the author feels it is imbued with, found in the word "Laughing!"
