In this poem I have found one example of personification.
1. “From her beacon hand glows world-wide welcome; her mild eyes command The air bridged harbor that twin cities frame.
This is personification because eyes, being nonhuman, are given the ability to command.
In this poem I have also found one example of a metaphor
1. “A mighty woman with a torch whose flame is imprisoned lightning, and her name is Mother of Exiles.”
This is a metaphor because it is comparing a flame and imprisoned lightning.
I believe this poem is about the powerful message behind The Statue of Liberty.
When the poem talks about not being like the brazen giant of Greek frame, I believe it is talking about how the Statue of Liberty not being like a typical Greek figure that is looked up to. Also, when the poem talks about the sea washed, sunset gates will stand A mighty woman with a torch, I believe this talks about the how The Statue of Liberty stands on Ellis Island, and sea water washes on shore. I believe the poet calls Lady Liberty the Mother of Exiles because Ellis Island was were immigrants would be admitted into America, or their freedom.
The poet seems to refer to a golden door. I believe this golden door is the freedom that America allows, and how it is a door to freedom. When the poet gives the Statue a quote about giving her poor and huddled masses that yearn to breathe free, I believe this talks about the immigrants, who came to America for the purpose of being free.
