Answer:
Frederick Douglass used personification and metaphor in his texts to show the oppressive nature of his master and also the ruthless nature of the slavery system that is suffocating his people.
Step-by-step explanation:
Frederick Douglass' memoir "The Narrative of the Life of Frederick Douglass" tells the life story of Douglass as he lives life as a slave in plantations and then get his freedom and work towards the freeing of his fellow black men. This book acts as an important source of knowing about the lives of slaves during the slavery system in America.
Using numerous figurative language in his text, Douglass elicits a deep sense of emotional connection to his readers. Example of such figurative language is the personification and metaphor in the text.
Personification can be seen Chapter X when he personifies "slavery" as a person. He states "there stood slavery, a stern reality, glaring frightfully upon us,—its robes already crimsoned with the blood of millions, and even now feasting itself greedily upon our own flesh", making it seem slavery as a man who is hard on his slaves.
Another is when he uses a metaphor in Chapter IX to compare his master Mr. Thomas Auld with Napoleon, "At times, he spoke to his slaves with the firmness of Napoleon and the fury of a demon ", giving the readers the impression of the ruthlessness of Mr. Auld.
By using these types of figurative languages, he gives an image of power and authority, the oppressive nature of the slavery system and the helplessness of the black people.
